Fine TTO™ is a patient-specific system intended for tibial tuberosity osteotomies (TTO) in skeletally mature patients.

The device is intended to assist in pre-operative planning and in guiding surgical instruments during the procedure, and should be used only when the anatomical landmarks required for planning can be clearly identified on the patient's radiographic images.

The Fine TTO™ system is designed specifically for tibial tuberosity osteotomies to adjust the alignment and positioning of the tibia for improved knee mechanics in skeletally mature patients. This system uses advanced imaging techniques, such as X-rays and CT scans, to create precise, patient-specific surgical guides. These guides assist surgeons in accurately cutting and repositioning the tibial tuberosity, ensuring the adjustments closely match the pre-surgical planning.

The primary function of Fine TTO™ is to facilitate precise bone cuts and ensure optimal placement according to the surgical plan, which is tailored to the patient's unique anatomy. The scientific concept behind Fine TTO™ relies on biomechanical principles of bone alignment and load distribution in the knee joint, aiming to restore the natural mechanics.

Device design and materials:

• Cutting Guides: Made from medical-grade polymers that are biocompatible and capable of providing the necessary rigidity and precision for bone cutting operations. These guides are designed for single use to ensure sterility and accuracy.
• Implants (Screws): Made from titanium alloy (Ti-6Al-4V ELI), known for its strength, biocompatibility. This material is standard in orthopedic applications and helps in the fixation process post-osteotomy.

Physical and performance characteristics:

• The system's design ensures that the cutting guides fit precisely to the patient's bone structure, reducing the risk of intraoperative errors and improving the predictability of the surgical outcome.
• The titanium screws used in the system provide strong, durable fixation that can withstand the mechanical forces exerted by the body weight and movement, supporting proper bone healing.

Intended Use

CORIOGRAPH Pre-Op Planning and Modeling Services are intended to provide preoperative planning for surgical procedures based on patient imaging, provided that anatomic landmarks necessary for generating the plan are identifiable on patient imaging scans.

Indications for Use

The CORIOGRAPH Pre-op Planning and Modeling Services are indicated for use for the following procedures:

• Unicondylar Knee Replacement (UKR)
• Total Knee Arthroplasty (TKA)
• Primary Total Hip Arthroplasty (THA)
• Primary Anatomic Total Shoulder Arthroplasty (aTSA)
• Primary Reverse Total Shoulder Arthroplasty (rTSA)

Coriograph Pre-Op Planning and Modeling Services (CORIOGRAPH) are Software as a Medical Device (SaMD) that provide pre-operative planning for orthopedic surgical procedures based on patient imaging, surgeon preferences and implant geometry. CORIOGRAPH is comprised of several medical software systems (modules), and these modules share a set of non-medical function software applications called the Case Processing System.

CORIOGRAPH is a Software Medical Device System. The medical function modules share a graphic user interface where the surgeon provides their case preferences and patient imaging, retrieves PDF plans generated by the Pre-Op Plan modules, and launches the Modeler modules.

CORIOGRAPH Pre-Op Plan Modules

Using patient-specific information, patient imaging, and surgeon inputs, a pre-operative plan is generated by Smith+Nephew personnel. The plan provides initial alignment recommendations to the surgeon on implant placement based on the geometries of the implant and of the generated bone models.

CORIOGRAPH Hip Modeler and CORIOGRAPH Shoulder Modeler Modules

CORIOGRAPH Hip Modeler and CORIOGRAPH Shoulder Modeler are web-based software applications intended for surgeons to modify the patient-specific pre-operative plan and to evaluate the impact of the modifications through the impingement analysis tools such as Impingement-free Range-of Motion (ROM) and Activities of Daily Living (ADL) simulations.

The provided text is a 510(k) clearance letter and summary for a medical device called CORIOGRAPH Pre-Op Planning and Modeling Services. It details the device's intended use, indications for use, and a comparison to predicate devices, focusing on the addition of shoulder arthroplasty procedures.

However, the document does not contain the specific information requested regarding acceptance criteria and the detailed study proving the device meets these criteria. It mentions non-clinical bench testing, software verification testing (IEC 62304), credibility evaluation of kinematic models and ADL simulations, and summative usability validation testing (IEC 62366). It states that "Design verification and validation testing demonstrated that CORIOGRAPH Pre-Op Planning and Modeling Services (v 3.0) meets all design requirements and is as safe and effective as its primary and secondary predicate devices." and "The credibility evaluation demonstrated that the kinematic models and Activities of Daily Living (ADLs) simulations utilized in the subject device are clinically relevant."

Crucially, it does not provide:

• Specific acceptance criteria for accuracy, precision, or performance metrics.
• Quantifiable reported device performance against those criteria.
• Sample sizes for test sets used for performance evaluation (other than mentioning "representative users" for usability).
• Data provenance (country of origin, retrospective/prospective) for performance data.
• Details on expert ground truth establishment (number of experts, qualifications, adjudication method).
• Information on MRMC comparative effectiveness studies.
• Standalone (algorithm-only) performance.
• Type of ground truth used (e.g., pathology, outcomes data) for clinical performance, if any.
• Sample size for the training set or how its ground truth was established.

The document is a high-level summary confirming regulatory clearance based on substantial equivalence, implying that the detailed testing data would have been part of the full 510(k) submission, but is not included in this public-facing summary.

Therefore, based only on the provided text, I cannot complete the requested tables and details about acceptance criteria and study proof. The document confirms that testing was done and results met requirements, but does not provide the specifics of those results or the criteria themselves.

The MedCAD® AccuStride™ System is intended to be used as a surgical instrument to assist in preoperative planning and/or in guiding the marking of bone and/or guide surgical instruments in nonacute, non-joint replacing osteotomies in the foot for adult and pediatric patients 12 years of age and older. The MedCAD® AccuStride™ System surgical guides are intended for single use only. The MedCAD® AccuStride™ System surgical guides should only be used when the anatomic landmarks necessary for pre-operative planning can be clearly identified on the patient's radiographic images (i.e., CT).

The MedCAD® AccuStride™ System is a collection of two individual pieces of software and associated additive manufacturing equipment intended to provide a variety of outputs to support non-acute, nonjoint replacing osteotomies in the foot. The system uses electronic medical images of the patient's anatomy or with input from the physician, to manipulate original patient images for planning and executing surgery. The patient specific outputs from the system includes anatomical models, surgical guides, and patient-specific case reports.

Following the MedCAD® Quality System and specific Work Instructions, trained employees utilize Commercial Off-The-Shelf (COTS) software to manipulate 3-D medical Computed Tomography (CT) images to create patient-specific physical and digital outputs. The process requires clinical input and review from the physician during and prior to delivery of the final outputs. It should be noted that the system is operated only by trained MedCAD employees, and the physician does not directly input information. The physician provides input for model manipulation and interactive feedback through viewing of digital models of system outputs that are modified by the engineer during the planning session.

The FDA 510(k) summary for the MedCAD® AccuStride™ System provides information about the device's acceptance criteria and the studies conducted. However, it does not provide detailed acceptance criteria and performance metrics for the software's ability to perform preoperative planning or guide marking, as typically expected for pure AI/ML software. Instead, the performance testing focuses on the physical components (surgical guides and anatomical models) produced by the system.

Here's an attempt to extract and infer the requested information based on the provided text, while also highlighting the limitations:

1. Table of Acceptance Criteria and Reported Device Performance

Important Note: The document focuses on the outputs of the system (surgical guides and anatomical models) rather than the standalone performance of the software in performing planning or marking. The "acceptance criteria" presented here are high-level outcomes of physical tests related to these outputs. There are no explicit metrics for the accuracy or efficacy of the "surgical instrument to assist in preoperative planning and/or in guiding the marking of bone" as a software component itself.

2. Sample Size Used for the Test Set and Data Provenance

• Wear Debris Testing: No specific sample size is provided beyond "Cutting / drilling instruments were used on a worst-case titanium surgical guide."
• Simulated Use Cadaver Validation Testing: No specific sample size is given for the number of cadavers used. It mentions "Guides were created to support bunion and metadductus, metatarsal 2+3, akin, and calcaneal osteotomies," implying a variety of cases were tested.
• Data Provenance: The cadaver validation testing is experimental ("simulated surgeries in cadavers") rather than derived from retrospective or prospective patient data. There is no information on the country of origin.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications

The document states, "The process requires clinical input and review from the physician during and prior to delivery of the final outputs." However, it does not specify the number of experts, their qualifications, or how they established the ground truth for the performance testing. The input and review from physicians appear to be part of the operational process rather than a formal ground truth establishment for a validation study.

4. Adjudication Method for the Test Set

No specific adjudication method (e.g., 2+1, 3+1) is mentioned for the performance testing. The "clinical input and review from the physician" is described as part of the normal workflow.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done

No MRMC comparative effectiveness study is mentioned. The performance testing focuses on the physical guides in a simulated cadaver environment, not on human readers' improvement with or without AI assistance.

6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done

The device description explicitly states: "the system is operated only by trained MedCAD employees, and the physician does not directly input information. The physician provides input for model manipulation and interactive feedback through viewing of digital models of system outputs that are modified by the engineer during the planning session." This indicates that the system is not a standalone AI algorithm without human-in-the-loop. It's a system where trained MedCAD employees (a human element) use software to develop outputs based on physician input and feedback. The performance testing reflects this human-in-the-loop process for generating the physical guides.

7. The Type of Ground Truth Used

• Wear Debris Testing: The ground truth for this test is implicit in "less than that reported in the literature to be safe." This refers to established safety thresholds for wear debris.
• Simulated Use Cadaver Validation Testing: The ground truth for this test appears to be "pre-surgical plans" for angle and position data, and subjective evaluation of "usability and fit." This is an engineering/design validation approach rather than pathology, expert consensus, or outcomes data from clinical cases.

8. The Sample Size for the Training Set

The document does not provide any information regarding a training set size. The system uses "Commercial Off-The-Shelf (COTS) software to manipulate 3-D medical Computed Tomography (CT) images." This suggests the core image manipulation algorithms might be pre-trained components within the COTS software, or the system does not involve machine learning in a way that requires a specifically defined "training set" for the AccuStride™ System's unique functionalities.

9. How the Ground Truth for the Training Set Was Established

Since no training set is described for the MedCAD® AccuStride™ System functionality, there is no information on how its ground truth was established.

The Newclip Patient-matched instrumentation non sterile PSI is indicated to be used as a surgical instrument to assist in pre-operative planning and/or in guiding surgical instruments in High Tibial Medial Opening or Closing Wedge Osteotomy, Distal Femoral Medial or Lateral Closing Wedge Osteotomy, High Tibial Lateral Closing Osteotomy, High Tibial Anterior Closing Osteotomy, Distal Femoral Lateral Opening Wedge Osteotomy and Distal Femoral Medial or Lateral Derotational Osteotomy, when the anatomic landmarks necessary for pre-operative planning can be clearly identified on the patient's radiographic images (i.e., computed tomography (CT)). Each PSI is designed to be compatible with implants from the Newclip High Tibial Osteotomy System or the Newclip Activmotion Range.

The Newclip Patient-matched instrumentation non sterile PSI are patient-matched devices (PSI Guides). The PSI Guides are surgical drilling/cutting guides that are additively manufactured (3D printed) and are designed to match the patient's anatomy. They are intended to assist in pre-operative planning and/or in guiding the marking of bone and/or guiding surgical instruments in non-acute, non-joint replacing osteotomies around the knee. They are single-use devices provided non sterilization by health care professionals before use. The Newclip Patient-matched instrumentation non sterile PSI can be used to facilitate implantation of the Newclip Activmotion Range devices. The purpose of this 510(k) notification is to add PSI Guides for High Tibial Lateral and Anterior Closing osteotomies. Material: Polyamide (PA2200).

The provided document is a 510(k) Summary for the Newclip Patient-matched instrumentation non sterile PSI. It includes information on the device, its intended use, and a comparison to a predicate device (K240415). The document also outlines the performance data used for verification and validation but lacks specific quantitative acceptance criteria or detailed study results for objective efficacy.

Here's a breakdown of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly state quantitative acceptance criteria in a table format for performance metrics. Instead, it describes acceptance in qualitative terms, primarily relying on comparison to the predicate device and satisfactory outcomes in simulated use.

2. Sample Size and Data Provenance

• Test Set Sample Size: The document does not specify a numerical sample size for the "worst-case guide design and manufacture" or the "simulated use" scenarios. It mentions "worst-case guide design" and "worst-case and subject PSI guides." This implies a limited, representative set rather than a large statistical sample.
• Data Provenance: The studies were conducted by Newclip Technics, a French company (Sponsor Address: F-44115 Haute-Goulaine, FRANCE). The studies were internal verification and validation activities. The country of origin of the data subjects (if any beyond the guides themselves) is not specified, nor whether it was retrospective or prospective. Given the nature of a 510(k) submission for mechanical surgical guides, it's likely a laboratory/simulated environment and not involving human patient data directly for performance validation at this stage.

3. Number of Experts and Qualifications for Ground Truth

• Manufacturing Validation: "Three NewClip operators with low, medium, and high levels of experience (novice, intermediate, expert)" were involved in the manufacturing validation. Their specific qualifications (e.g., years of experience, specific certifications) beyond their experience level are not detailed.
• Simulated Surgery: "The same three novice surgeons" performed the simulated use. Their specific qualifications (e.g., years of surgical experience, board certification) are not detailed other than being designated "novice."

4. Adjudication Method

• The document does not describe a formal adjudication method (e.g., 2+1, 3+1) for establishing ground truth or evaluating performance. For the manufacturing validation, it involved comparison of dimensions, design, correction, and placement, presumably against predefined design specifications or an established 'true' state. For the simulated surgery, it seems the observation of the three novice surgeons' ability to achieve the desired outcomes (positioning, correction, hinge preservation) against unnamed criteria formed the basis of acceptability.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• No MRMC comparative effectiveness study was done. The performance data section describes internal verification and validation activities rather than a comparative study of human readers with and without AI assistance. The device is a surgical guide, not an AI diagnostic tool that assists human readers in interpreting images.

6. Standalone Performance Study

• The performance data described focuses on the device itself (manufacturing precision and simulated usability) and its comparison to a predicate device. It is a standalone assessment of the algorithmic design and physical manufacturing of the guides, though its use is demonstrated in a simulated human-in-the-loop context (by surgeons). The "algorithm" here refers to the design software that creates the patient-matched guides.
  • Manufacturing Test: The assessment of "precision and accuracy of design, correction, and manufacture" of the PSI guides can be considered a standalone algorithm/device performance evaluation as it assesses the output of the CAD/CAM process.
  • Simulated Use: This evaluates the physical guides in use by surgeons, which is a human-in-the-loop scenario, but the performance of the guide itself (its fit, its ability to guide instruments correctly) is the primary focus.

7. Type of Ground Truth Used

• Manufacturing Validation: The ground truth for manufacturing precision and accuracy would be the original digital design specifications of the patient-matched instrumentation. The manufactured guides were compared against these known dimensions and design elements.
• Simulated Surgery: The ground truth for the simulated surgery was the planned surgical correction and the expected function of the guide (e.g., correct positioning, preservation of the hinge). This is established based on the pre-operative planning and surgical goals.

8. Sample Size for the Training Set

• The document does not mention a "training set" in the context of an AI/machine learning model. The device (Patient-matched instrumentation) leverages CT images to create customized physical guides, which are then 3D printed. There is no indication of an AI algorithm being "trained" on a dataset in the typical sense. The "training" here would be for the CAD/CAM software to accurately generate the patient-specific geometry based on the CT scan data, which is typically a deterministic process rather than a machine learning one.

9. How the Ground Truth for the Training Set Was Established

• As no training set for an AI/ML model is indicated, this question is not applicable based on the provided text. The "ground truth" for the device's function relies on accurate anatomical segmentation from CT scans and precise mechanical design parameters encoded in the CAD/CAM software.

The Newclip Patient-matched instrumentation non sterile PSI is indicated to be used as a surgical instrument to assist in pre-operative planning and/or in guiding surgical instruments in High Tibial Medial Opening or Closing Wedge Osteotomy, Distal Femoral Medial or Lateral Closing Wedge Osteotomy. Distal Femoral Lateral Opening Wedge Osteotomy and Distal Femoral Medial or Lateral Derotational Osteotomy, when the anatomic landmarks necessary for pre-operative planning can be clearly identified on the patient's radiographic images (i.e., computed tomography (CT)). Each PSI is designed to be compatible with implants from the Newclip High Tibial Osteotomy System or the Newclip Activmotion Range.

The Newclip Patient-matched instrumentation non sterile PSI are patient-matched devices (PSI Guides). The PSI Guides are surgical drilling/cutting quides that are additively manufactured (3D printed) and are designed to match the patient's anatomy. They are intended to assist in pre-operative planning and/or in guiding the marking of bone and/or guiding surgical instruments in non-acute, non-joint replacing osteotomies around the knee. They are single-use devices provided non sterilization by health care professionals before use. The Newclip Patient-matched instrumentation non sterile PSI can be used to facilitate implantation of the Newclip Activmotion Range devices. The primary purpose of this 510(k) notification is to add PSI Guides for closingwedge and derotation osteotomies.

The provided text describes the Newclip Patient-matched instrumentation non sterile PSI, a device used in osteotomy procedures around the knee. The 510(k) summary focuses on demonstrating substantial equivalence to predicate devices, but it does not include explicit acceptance criteria, detailed study designs, or specific performance metrics typically expected for AI/Machine Learning-enabled devices.

The device is described as "patient-matched instrumentation," which implies that the design process involves processing patient imaging data (CT scans) to create custom surgical guides. However, the document does not elaborate on the algorithmic aspects of this patient-matching process or how its accuracy is evaluated in a standalone or comparative study setting.

Given the information provided, here's an attempt to answer the questions, highlighting the limitations due to the lack of specific details concerning AI/ML evaluation as per your request:

1. Table of acceptance criteria and the reported device performance

Based on the provided document, explicit quantitative acceptance criteria for the "Newclip Patient-matched instrumentation non sterile PSI" are not stated. The performance is broadly described in terms of "precision and accuracy" in simulated-use cadaver surgeries. No specific numerical thresholds or target values are provided.

2. Sample size used for the test set and the data provenance

The document mentions "simulated-use cadaver surgeries" for performance verification. However:

• Sample Size for Test Set: Not specified. The number of cadavers or surgical approaches evaluated is not provided.
• Data Provenance: Not specified, but given the nature of cadaver studies, it would be laboratory-based rather than from real-world patient data. The study is described as "simulated-use," suggesting a prospective evaluation within a controlled environment.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

The document states "Surgeon evaluation of precision and accuracy."

• Number of Experts: Not specified.
• Qualifications of Experts: Identified as "Surgeon," but no further details such as specialty (e.g., orthopedic surgeon), years of experience, or specific board certifications are provided.

4. Adjudication method for the test set

The document only states "Surgeon evaluation." There is no mention of an adjudication method (such as 2+1, 3+1 consensus, or independent review) for establishing ground truth or assessing outcomes in the simulated-use cadaver surgeries.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

• MRMC Study: Not mentioned. The study described is a "Surgeon evaluation of precision and accuracy based on simulated-use cadaver surgeries." This focuses on the performance of the device itself in guiding surgical actions, rather than an MRMC study comparing human reader performance with and without AI assistance for tasks like diagnosis or planning.
• Effect Size of AI/Human Improvement: Not applicable, as no such MRMC study is described. The device's role is to guide surgical instruments, not to assist human readers in interpreting images or making diagnostic decisions.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The document describes the "patient-matched instrumentation" as derived from CT images and used to guide surgical instruments. This implicitly means there is computational work done to generate these custom guides. However, no specific standalone algorithm-only performance study results are provided. The evaluation mentioned is "Surgeon evaluation of precision and accuracy based on simulated-use cadaver surgeries," which represents a human-in-the-loop scenario where the surgeon uses the device. A standalone validation of the algorithm's ability to precisely match anatomy or generate optimal guide designs is not explicitly detailed.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc)

For the "precision and accuracy" evaluation in cadaver surgeries, the ground truth or reference standard against which the device's performance was measured is not explicitly stated. It's likely an assessment by the evaluating surgeon(s) based on intra-operative observation or post-operative measurements of the osteotomy characteristics (e.g., angles, cuts) against the pre-operative plan, but the method for establishing this ground truth is not detailed.

8. The sample size for the training set

The document does not provide any information regarding a training set sample size. This suggests that if an algorithm is used for patient-matching guide design, it was either not developed using a distinct "training set" in the machine learning sense, or the details of its development and validation outside of the simulated-use cadaver study are not included in this summary. The process likely involves computational design based on individual patient CT data rather than a generalizable AI model trained on a large dataset.

9. How the ground truth for the training set was established

Not applicable, as no information about a training set is provided.

This service is an additional offering being introduced by Smith & Nephew to allow for preoperative planning for surgical procedures based on patient imaging for total knee arthroplasty (TKA) and unicondylar knee replacement (UKR). The CORIOGRAPH Knee Pre-Op Plans will be generated for specific patients and anatomy by Smith and Nephew personnel using the CORIOGRAPH Knee Pre-Op Plan Software System V1.0, which is the subject of this submission. The CORIOGRAPH Knee Pre-Op Plans will output bone models of the patient anatomy and will generate patient-specific pre-operative plans which may be used on the REAL INTELLIGENCE CORI Surgical System.

The provided text is a 510(k) summary for the CORIOGRAPH Knee Pre-Op Plan. It discusses the device's substantial equivalence to a predicate device and details non-clinical testing. However, it does not contain the specific information required to complete all sections of your request regarding acceptance criteria and a study proving those criteria are met.

Here's a breakdown of what can be answered and what information is missing:

1. A table of acceptance criteria and the reported device performance

The document states, "Verification and validation testing demonstrated the safety and effectiveness of the software applications used in the CORIOGRAPH Knee Pre-Op Plan and demonstrated the safety and effectiveness of the generated CORIOGRAPH Knee Pre-Op Plan when used as an input to the CORI Surgical System. Summative usability testing demonstrated that participating surgeons were able use the subject device safely and effectively in a simulated use environment. Smith and Nephew, Inc. has concluded that all design inputs have been met and that the verification and validation testing performed did not raise any new questions of safety or effectiveness."

This is a general statement of compliance, not a detailed table of specific acceptance criteria (e.g., accuracy metrics, specific tolerances) and their corresponding reported performance values. Therefore, a table cannot be fully constructed.

2. Sample size used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective)

This information is not provided in the text. The document refers to "verification and validation testing" and "summative usability testing" but does not specify the sample size for these tests or the origin/nature of the data used.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g. radiologist with 10 years of experience)

This information is not provided in the text. The document mentions "participating surgeons" in the usability testing, but their number or specific qualifications (beyond being surgeons) are not detailed. It does not mention experts establishing ground truth for a test set in the context of performance metrics.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

This information is not provided in the text.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

The document does not describe an MRMC comparative effectiveness study where human readers' performance with and without AI assistance was evaluated. The device is a "Knee Pre-Op Plan" which suggests it aids in surgical planning, not necessarily in interpretation tasks typically associated with MRMC studies with human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

The document states, "Verification and validation testing demonstrated the safety and effectiveness of the software applications used in the CORIOGRAPH Knee Pre-Op Plan and demonstrated the safety and effectiveness of the generated CORIOGRAPH Knee Pre-Op Plan when used as an input to the CORI Surgical System." This implies standalone testing of the software's output, as well as its interaction as an input to another system. However, specific metrics of "algorithm-only" performance are not provided.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

This information is not explicitly provided in the text. Given the device provides "pre-operative planning for surgical procedures based on patient imaging," the ground truth for evaluating its accuracy would likely be related to the accuracy of anatomical landmark identification, implant positioning, or surgical outcomes, but this is not specified.

8. The sample size for the training set

This information is not provided in the text. The document discusses "software applications" and "planning tools and processes" but does not detail any machine learning models or training sets.

9. How the ground truth for the training set was established

This information is not provided in the text, as no training set details are given.

• If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
• The type of ground truth used (expert consensus, pathology, outcomes data, etc): Not applicable.
• The sample size for the training set: Not applicable.
• How the ground truth for the training set was established: Not applicable.

Based on the provided text, here is what can be extracted regarding the "study" that proves the device meets acceptance criteria:

The "study" or rather the justification for meeting acceptance criteria is a demonstration of substantial equivalence to a previously cleared predicate device.

1. A table of acceptance criteria and the reported device performance

The document does not provide a table of acceptance criteria and reported device performance in the context of a new clinical or non-clinical performance study. Instead, the device's acceptance is based on its substantial equivalence to a predicate device already on the market.

2. Sample sized used for the test set and the data provenance

No new test set was used or described for this 510(k). The regulatory submission relies on the substantial equivalence to the predicate device K231314.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable, as no new test set requiring expert ground truth establishment for performance evaluation is described.

4. Adjudication method for the test set

Not applicable, as no new test set is described.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

No MRMC comparative effectiveness study is mentioned.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done

No standalone algorithm performance study is mentioned.

7. The type of ground truth used

Not applicable, as no new performance study is described. The acceptance is based on substantial equivalence.

8. The sample size for the training set

Not applicable, as no new algorithm development requiring a training set is described. The device is a patient-specific surgical guide system, not an AI/ML algorithm that identifies or diagnoses.

9. How the ground truth for the training set was established

Not applicable.

Summary of "Study" to Prove Acceptance:

The provided document indicates that the Fine Osteotomy™ system (K240066) achieves acceptance (i.e., substantial equivalence to a predicate device) through the following:

• Non-Clinical and/or Clinical Tests Summary & Conclusions (21 CFR 807.92(b)):
  • Verification and validation (V&V) activities included:
    • Mechanical Engineering Analysis of updated and new single-use instruments demonstrating no new worst-case scenarios.
    • Modification of Shelf-Life Referential for Fine Osteotomy Systems.

This implies that the key "study" involved analyzing the updated and new single-use instruments (from an engineering perspective) and reassessing the shelf-life, to confirm that these changes do not alter the fundamental safety and effectiveness demonstrated by the predicate device. The performance data for the core technology is implicitly referenced as that of the predicate device (K231314).

Ask a specific question about this device

The Newclip Patient-matched instrumentation non sterile PSI is indicated to be used as a surgical instrument to assist in pre-operative planning and/or in guiding surgical instruments in High Tibial Medial Opening Wedge Osteotomy and Distal Femoral Lateral Opening Wedge Osteotomy, when the anatomic landmarks necessary for pre-operative planning can be clearly identified on the patient's radiographic images (i.e., computed tomography (CT)). Each PSI is designed to be compatible with implants from the Newclip High Tibial Osteotomy System or the Newclip Activmotion Range.

The Newclip Patient-matched instrumentation non sterile PSI are patient-matched devices. The subject devices are surgical drilling/cutting quides that are additively manufactured (3D printed) and are designed to match the patient's anatomy. They are intended to assist in pre-operative planning and/or guiding surgical instruments in orthopaedic surgery (High Tibial Medial Opening Wedge Osteotomy and Distal Femoral Lateral Opening Wedge Osteotomy). They are single-use devices provided non sterile for sterilization by health care professionals before use. The Newclip Patient-matched instrumentation non sterile PSI can be used to facilitate implantation of Newclip High Tibial Osteotomy System or the Newclip Activmotion Range devices.

The provided text is a 510(k) summary for the Newclip Patient-matched instrumentation non sterile PSI. It does not contain the specific acceptance criteria or details of a study structured to prove the device meets said criteria as requested.

The document states that "Verification and validation (V&V) activities included... Surgeon evaluation of precision and accuracy based on human clinical cases." It further mentions that "Precision and accuracy of the subject device was demonstrated in published human clinical studies by surgeon-users on patients in Europe using Newclip Patient-matched instrumentation non sterile PSI guides." However, it does not provide:

• A table of acceptance criteria and reported device performance.
• Sample size for the test set or data provenance. (It refers to "human clinical cases" and "published human clinical studies" but gives no numbers or details on whether the data was retrospective or prospective, or from which specific countries beyond "Europe.")
• Number and qualifications of experts for ground truth.
• Adjudication method.
• If a multi-reader multi-case (MRMC) comparative effectiveness study was done, or any effect size for human readers improving with/without AI assistance. (This device is a patient-matched surgical guide, not an AI or imaging diagnostic tool, so an MRMC study is unlikely to be relevant in the traditional sense, but the question was asked.)
• If a standalone performance (algorithm only) was done. (Again, not directly applicable as this is a physical surgical guide.)
• The type of ground truth used.
• Sample size for the training set.
• How ground truth for the training set was established.

The document primarily focuses on demonstrating substantial equivalence to a predicate device (SurgiCase Orthopaedics, SurgiCase Connect, SurgiCase Guides). It lists verification and validation activities conducted, but these are described in broad terms rather than as a detailed study report with specific metrics and results.

Therefore, based solely on the provided text, I cannot fulfill the request for detailed information about acceptance criteria and a study proving those criteria were met.

If this were a medical imaging AI device, the lack of such details in an FDA 510(k) summary would be a red flag. However, for a patient-matched surgical instrument, the V&V activities mentioned (surgeon evaluation, precision/accuracy in design/manufacturing, wear testing, cleanliness/sterilization, dimensional verification) are typical, though the specific data from these activities is not included in this summary.
