    AI/ML Overview

    The provided text is a 510(k) summary for a medical device called "MectaScrew Extension." This document outlines the device's characteristics, its intended use, and its comparison to predicate devices to establish substantial equivalence.

    Crucially, the document states: "No clinical studies were conducted." This means there is no study evaluating the device's performance against pre-defined acceptance criteria with human subjects or actual clinical outcomes in the format you've requested.

    Therefore, I cannot provide information on:

    • A table of acceptance criteria and reported device performance (as no clinical performance criteria or results are given).
    • Sample size used for the test set and data provenance.
    • Number of experts and their qualifications used to establish ground truth.
    • Adjudication method for the test set.
    • MRMC comparative effectiveness study or its effect size.
    • Standalone performance.
    • Type of ground truth used (as no clinical ground truth was established from a study).
    • Sample size for the training set (no AI/ML component described).
    • How ground truth for the training set was established (no AI/ML component described).

    The document focuses on non-clinical studies (design validation, performance testing like torque resistance and pull-out strength, MR safety, pyrogenicity, and biocompatibility) to demonstrate substantial equivalence to predicate devices. These non-clinical tests would have their own internal acceptance criteria, but these are not for the "device performance" in the clinical sense you are asking for.

    In summary, based on the provided text, the MectaScrew Extension did not undergo a clinical study to prove its performance against acceptance criteria in human use. Its clearance was based on demonstrating substantial equivalence through non-clinical data and comparison to existing legally marketed devices.

    AI/ML Overview

    I am sorry, but the provided text describes a 510(k) premarket notification for a medical device (hip implants), which focuses on demonstrating substantial equivalence to predicate devices based on non-clinical performance data and design validation.

    The information you are asking for, such as:

    • Acceptance criteria and reported device performance (in a table)
    • Sample size and data provenance for a "test set"
    • Number of experts and their qualifications for ground truth establishment
    • Adjudication method for a test set
    • Multi-Reader Multi-Case (MRMC) comparative effectiveness study
    • Standalone algorithm performance
    • Type of ground truth used (expert consensus, pathology, outcomes data, etc.)
    • Sample size for the training set
    • How ground truth for the training set was established

    These elements are typically requested for AI/Machine Learning-based medical devices that perform diagnostic or interpretative functions, where the device's "performance" is measured in terms of metrics like sensitivity, specificity, accuracy, or reader improvement, and involves substantial data sets with established ground truth.

    The provided document explicitly states: "No clinical studies were conducted." This further confirms that the type of performance evaluation (and associated data provenance, ground truth establishment, expert involvement, etc.) relevant to AI/ML devices was not part of this specific 510(k) submission.

    Therefore, I cannot extract the information you requested from the provided text for the following reasons:

    1. Device Type: This is a physical implant, not an AI/ML diagnostic or interpretative device.
    2. Regulatory Pathway: The 510(k) for this device focuses on demonstrating substantial equivalence through engineering and biomechanical testing, not through AI model performance metrics.
    3. Absence of Clinical Studies: The document explicitly states no clinical studies were performed, which is where performance data related to human-in-the-loop or standalone AI would typically come from.
    4. No AI Mentioned: There is no mention of AI, machine learning, algorithms for interpretation, or any kind of software performance criteria beyond mechanical and material properties.

    The "Performance Data" section in the document (Section VII) lists non-clinical studies such as:

    • Design Validation (cadaver workshops, evaluation forms, rationales)
    • Performance Testing (stereological evaluation, static and fatigue shear tests, tension tests, ROM evaluation, fatigue and deformation tests, liner stability tests, mechanical tests for screws)
    • Pyrogenicity testing
    • Biocompatibility assessment

    These are typical tests for a physical orthopedic implant seeking 510(k) clearance, not for an AI/ML software as a medical device (SaMD).

    Intended Use

    The Shoulder NextAR™ RSA Platform supports the surgeon during glenoid implantation in reverse shoulder replacement procedures providing information on bone preparation, instrument guidance, and implant positioning. The Shoulder NextAR™ RSA Platform works in conjunction with NextAR™ stereotaxic instruments and general surgical instruments to implant the Medacta Shoulder System Reverse Shoulder Arthroplasty). As an optional display, the smart glasses can be used auxiliary to the Shoulder NextAR™ Platform to view the same 2D stereotaxic information as presented by the Shoulder NextARTM Platform.

    The Shoulder NextAR™ stereotaxic instruments are to support the surgeon during specific orthopedic surgical steps by providing information on bone preparation, instrument guidance, and implant positioning. Once registered, the NextAR™ stereotaxic instruments provide reference to a patient's rigid anatomical structures on the surface of the glenoid that are identified relative to preoperative C.T. based planning.

    The smart glasses should not be relied upon solely and should always be used in conjunction with the primary computer display.

    Device Description

    The Shoulder NextAR™ RSA Platform is a CT based computer-assisted surgical navigation platform used to perform a reverse shoulder arthroplasty on the glenoid and includes the following components:

    • PC based hardware platform; (K193559 and K202152)
    • optical tracking system; (K193559 and K202152)
    • Augmented Reality glasses; (K193559 and K202152)
    • Platform (K193559 and K202152)
    • navigation software which displays information to the surgeon in real-time;
    • Reusable surgical instruments to perform the surgical steps of a shoulder reverse arthroplasty ● on the glenoid.

    The system operates on the common principle of stereotaxic technology in which markers are mounted on the bones and an infrared camera is used to monitor the spatial location of the markers. Tracking sensors attached to the scapula and surgical instruments enable the surgeon to view the position and orientation of scapula and instrumentation relative to preoperative data in real-time while performing the surgical procedure. The tracking sensors are provided sterile.

    Shoulder NextAR™ RSA Platform aids the surgeon in executing the surgical plan by visualizing all the information in real time on a screen monitor.

    The NextAR™ RSA system is intended to assist the surgeon in executing a preoperative surgical planning. The navigation platform tracks the surgical instruments in real-time and displays intraoperative and planned surgical parameters on a screen, thus allowing the surgeon to match the intraoperative parameters with the planned ones.

    Specifically, the navigation system utilizes established technologies of navigation and via an active infrared camera rigidly coupled with the scapula and an active infrared tracker that can be rigidly coupled to the surgical instruments. The registration of the patient's scapula on the preoperative scapula model is performed through the use of dedicated surgical instruments (pointers) and a dedicated registration algorithm.

    AI/ML Overview

    The provided text describes the 510(k) summary for the Medacta International SA NextAR™ RSA Platform, a CT-based computer-assisted surgical navigation platform for reverse shoulder arthroplasty. The performance data section is brief, stating that testing was conducted according to written protocols with acceptance criteria based on standards, and mentions a "cadaver study" and an "in vitro study." However, it does not provide specific details about the acceptance criteria themselves, the reported device performance against those criteria, the sample sizes, expert qualifications, ground truth methods, or any MRMC study results. The text indicates that some studies were accepted from previous submissions of related devices (NextAR™ TKA Platform K193559 and K202152), but these are general safety and performance tests (biocompatibility, sterilization, shelf-life, electrical safety, EMC, mechanical/optical properties) and not performance data explicitly proving the navigation system's accuracy or effectiveness in its specific use case for shoulder arthroplasty.

    Therefore, based solely on the provided text, I cannot populate most of the requested information regarding the acceptance criteria and the study that proves the device meets them. The document states that the studies were performed "in support of a substantial equivalence determination," but it does not present the detailed results of these specific performance studies.

    Here's a breakdown of what can be inferred or what is explicitly missing:


    Acceptance Criteria and Device Performance (As much as can be extracted from the provided text)

    The document broadly states that "Testing was conducted according to written protocols with acceptance criteria that were based on standards." However, it does not present a table of specific acceptance criteria or the reported device performance against them.

    Study Details:

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

      • Not provided in the document. The document mentions "acceptance criteria that were based on standards" but does not list them or the performance results.
    2. Sample sized used for the test set and the data provenance:

      • The document mentions a "cadaver study" and an "in vitro study."
      • Sample Size: Not specified for either study.
      • Data Provenance: Not specified (e.g., country of origin). Both appear to be prospective experimental studies (cadaveric and in vitro).
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

      • Not specified. The document does not describe how ground truth was established for the cadaver or in vitro studies, nor does it mention experts for this purpose.
    4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

      • Not specified.
    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:

      • Not specified. The document does not mention an MRMC study or any assessment of human reader improvement with AI assistance. The device is a surgical navigation platform, not an AI diagnostic tool that assists human readers.
    6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

      • The document mentions "performance testing to evaluate mechanical and optical properties" and "software validation," which would likely involve standalone performance evaluations of system components and the algorithm. However, specific details of these tests as they relate to clinical accuracy or a defined "standalone" performance metric for the navigation itself are not elaborated. The cadaver and in vitro studies would assess the system's performance, but how "standalone" vs. "human-in-the-loop" was defined and measured is not clear.
    7. The type of ground truth used (expert consensus, pathology, outcomes data, etc):

      • Not specified. For a navigation system, ground truth would typically refer to highly accurate measurements of actual bone or instrument positions relative to an established plan. The method (e.g., CMM measurements, highly accurate image registration) is not detailed.
    8. The sample size for the training set:

      • Not applicable/Not specified. The document describes a navigation system based on "established technologies of navigation" and "dedicated registration algorithm," rather than a machine learning model that requires a "training set" in the conventional sense for AI. If elements of the "software validation" involved training machine learning components, this is not disclosed.
    9. How the ground truth for the training set was established:

      • Not applicable/Not specified, for the same reasons as #8.

    Summary of Missing Information:

    The provided 510(k) summary is very high-level regarding the specific performance studies. It confirms that a cadaver study and an in vitro study were performed to support substantial equivalence, but it omits the critical details of these studies, such as:

    • Specific quantitative acceptance criteria.
    • The numerical results obtained from the device (e.g., accuracy, precision values).
    • The number of samples (cadavers, in vitro setups).
    • The methodologies for establishing ground truth.
    • Any details about expert involvement or adjudication.

    This type of detailed information is typically found in the full testing reports or sections within the 510(k) submission that are not publicly available in this summary format.

    Device Description

    The MPACT Extension implants subject of this submission are twelve (12) sizes of Cancellous Bone Screws.

    The subject devices are sterile implantable devices intended to be used during Total Hip Arthroplasty.

    Analogously to the predicate Cancellous Bone Screws flat head (K103721 and K132879), the subject Cancellous Bone Screws, are made of titanium alloy (Ti6-A14-V) according to ISO 5832-3:2016 Implants for Surgery - Metallic materials - Part 3: Wrought titanium 6-aluminum 4vanadium allov. As the predicate devices, they have been designed with a thread diameter of 6.5 mm to provide fixation of implants to the cancellous bone. They can be coupled with implants that have dedicated fixation holes with a spherical seat shape of Ø8mm.

    AI/ML Overview

    This document is a 510(k) Premarket Notification from the FDA regarding a medical device called "MPACT Extension," which consists of Cancellous Bone Screws for total hip arthroplasty.

    Based on the provided text, a conventional "acceptance criteria" and "study proving the device meets the acceptance criteria" in the context of an AI/Software as a Medical Device (SaMD) study (as implied by the detailed breakdown requested in the prompt) were not performed. The document describes the acceptance criteria and study for a physical implantable medical device, specifically cancellous bone screws, not a software or AI product.

    Therefore, many of the requested points, such as AI-specific acceptance criteria, multi-reader multi-case studies, ground truth establishment for training sets, etc., are not applicable to this document.

    However, I can extract the relevant information provided for the device described:


    1. A table of acceptance criteria and the reported device performance (for the hardware device):

    The document does not explicitly present a table of numerical "acceptance criteria" for the performance of the cancellous bone screws in the way one might for a software or AI algorithm (e.g., target accuracy, sensitivity). Instead, acceptance is based on demonstrating substantial equivalence to predicate devices through various tests and material properties. The performance is assessed through meeting standards and showing compatibility.

    CategoryAcceptance Criteria (Implied by Regulatory Standards)Reported Device Performance

    Design ValidationDesign must be validated for functionality and compatibility.DESIGN VALIDATION: "Cancellous Bone Screw Ø6.5 design Validation rationale A1 item 3" and "Cancellous Bone Screw Ø6.5 acetabular shell compatibility Validation rationale A2 item 3."

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

    • Sample Size for Test Set: Not specified in the document in terms of traditional "test sets" for a software algorithm. The "test set" for this physical device would refer to the number of screws tested during design validation, biocompatibility, and sterility testing. This number is not provided.
    • Data Provenance: Not applicable in the context of a software data set (e.g., country of origin, retrospective/prospective). The document describes non-clinical studies performed on the device itself.

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

    • Not applicable. This pertains to a physical medical device, not a software/AI product requiring expert ground truth for image interpretation or similar. The "ground truth" for this device would be its physical and chemical properties and mechanical performance as evaluated through standard laboratory testing.

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

    • Not applicable. This is a method for reconciling differences in expert annotations for AI/software ground truth.

    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, an MRMC comparative effectiveness study was not done. The device is a physical implant, not an AI or diagnostic software tool.
    • Effect size: Not applicable.

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

    • Not applicable. This refers to AI algorithm performance.

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

    • For this physical device, the "ground truth" is established through objective laboratory testing against recognized standards (e.g., ISO for materials, biocompatibility tests, pyrogenicity tests). It's about demonstrating the device's physical properties and safety characteristics meet established benchmarks, rather than interpretation of data by experts.

    8. The sample size for the training set:

    • Not applicable. This refers to an AI training set.

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

    • Not applicable. This refers to an AI training set.

    Summary of the Study that Proves the Device Meets Acceptance Criteria (as described in the document):

    The acceptance of the MPACT Extension device (Cancellous Bone Screws) is based on demonstrating its substantial equivalence to established predicate devices (Medacta International SA, MPACT, K103721 and MPACT Extension, K132879). This substantial equivalence is supported by a series of non-clinical studies:

    • Design Validation: Specific rationales were provided for the design validation of the Ø6.5 Cancellous Bone Screw and its compatibility with acetabular shells. This ensures the device's design is adequate for its intended use.
    • Biocompatibility Evaluation: Performed according to ISO 10993, demonstrating the device is suitable for implantation without adverse biological reactions.
    • Shelf-Life Testing: Conducted according to ISO 11607-1 and ISO 11607-2, ensuring the device maintains its properties and sterility over its intended shelf life.
    • Pyrogenicity Testing: Bacterial Endotoxin Test (LAL test) per European Pharmacopoeia §2.6.14 (equivalent to USP chapter <85>) and Pyrogen test per USP chapter <151> were performed to ensure the device is not pyrogenic.

    No clinical studies were conducted for this 510(k) submission, as stated under "Clinical Studies" in Section VII. The substantial equivalence was determined based on the comparison of intended use, design, technological characteristics, and the non-clinical design validations.

    Intended Use

    The M.U.S.T. Pedicle screws system is intended for posterior non-cervical pedicle fixation (T1-S2/ilium) and non-pedicle fixation, or anterolateral fixation (78-L5). These devices are indicated as an adjunct to fusion for all of the following indications: degenerative disc disease (defined as back pain of discogenic origin with degeneration of the disc confirmed by history and radiographic studies); spondylolisthesis; trauma (i.e., fracture or dislocation); spinal stenosis; curvatures (i.e., scoliosis, kyphosis, and/or lordosis); tumor; pseudoarthrosis; and failed previous fusion in skeletally mature patients.

    Device Description

    The M.U.S.T. Midline Cortical (MC) Screw System is intended to be used as part of the M.U.S.T. Pedicle Screw system (K12115, K132878, K141988, K153664, K162061, K171170, K171758, K193365) for the stabilization and the fusion of the lumbar and thoracic spine. The M.U.S.T. pedicle screw system includes cannulated or non-cannulated poly-axial pedicle screws (K121115, K132878, K153664), cannulated or non-cannulated mono-axial pedicle screws (K132878), set screws (K121115, K171758), straight and pre-bent rods (K12115, K141988, K162061), lateral connectors (K162061) and cross connectors (K132878, K193365). The M.U.S.T. pedicle screw system also includes the enhanced screws and rods designed for percutaneous surgery (K141988).

    The M.U.S.T. Midline Cortical (MC) Screw System introduce new polyaxial screws and reduction screws (solid and cannulated), developed with a focus on Midline Cortical Trajectory approach. The devices subject of this submission are:

    • M.U.S.T. MC polyaxial screws Solid
    • M.U.S.T. MC polyaxial screws Cannulated
    • M.U.S.T. MC polyaxial reduction screws Solid
    • M.U.S.T. MC polyaxial reduction screws Cannulated

    Intended purpose and the performance specification of the devices are equivalent to the ones of the current US cleared portfolio: polyaxial screws are already used in the MUST implant construct.

    The M.U.S.T. Midline Cortical (MC) Screws and the Inlay are manufactured from Ti-6Al-4V ELI (ISO 5832-3 Implants for surgery -Metallic materials - Part 3: Wrought titanium 6-vanadium alloy + ASTM F136 Standard Specification for Wrought Titanium-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401); the Tulip and the Setscrew are made of Co-Cr-Mo alloy according to ISO 5832-12:2019, Implants for Surgery - Metallic materials -Part 3: Wrought cobalt-chromium-molybdenum alloy, the same material of the previous cleared M.U.S.T. Pedicle Screw (K153664, K121115, K171170).

    AI/ML Overview

    Here's an analysis of the provided text regarding the acceptance criteria and study for the M.U.S.T. Midline Cortical (MC) Screw System:

    1. Table of acceptance criteria and the reported device performance:

    The provided document does not explicitly state specific quantitative acceptance criteria for many of its tests. Instead, it describes various tests performed and implies that the results of these tests met the necessary standards for substantial equivalence. For instance, mechanical evaluations were conducted "according to ASTM F1717-18" without specifying the pass/fail thresholds. The "geometrical analysis" was performed "to ensure that the implant has sufficient fixation" and "in comparison to approved and marketed implants," implying an acceptance of similarity or non-inferiority.

    To create a table, I will infer the performance reported based on the conclusion of substantial equivalence.

    Evaluation/TestAcceptance Criteria (Inferred)Reported Device Performance/Outcome
    Non-Clinical Studies
    DESIGN VALIDATION
    Wetlab (Surgical Technique)Satisfactory performance and usability by experienced surgeons according to the MUST MC surgical technique.Performed by 3 experienced surgeons according to MUST MC surgical technique; implies satisfactory validation.

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

    • Sample Size:
      • Wetlab (Surgical Technique): The "cadaver labs were performed by 3 experienced surgeons." This refers to the number of users of the devices, not a number of distinct device units or anatomical samples tested. The number of cadavers used is not specified.
      • Geometrical Analysis: Not specified, but it would involve measurements of the (new) M.U.S.T. MC implants and approved/marketed implants.
      • Mechanical Performance Testing (ASTM F1717): Not specified. ASTM F1717 standards generally define specific sample sizes (e.g., minimum of 5 samples per test condition for static tests, 3-6 for dynamic fatigue). The document states "Worst Case definition... for mechanical testing," implying specific samples were chosen.
      • Pyrogenicity Assessment: Not specified, but would align with standard biological testing protocols.
    • Data Provenance (Country of Origin, Retrospective/Prospective): Not explicitly stated. These were non-clinical studies conducted for regulatory submission. Given the manufacturer is Medacta International SA (Switzerland) and its US counterpart Medacta USA, the testing could have been conducted in any accredited lab globally. They are prospective tests conducted on the device components and system.

    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):

    • Number of Experts: 3 experienced surgeons were used for the wetlab (surgical technique validation).
    • Qualifications of Experts: They are described as "experienced surgeons." No further detailed qualifications (e.g., years of experience, specific sub-specialty) are provided in this document.

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

    The document mentions "3 experienced surgeons" performed the wetlab. However, it does not describe an adjudication method for their observations or findings. It simply states the lab was performed "according to MUST MC surgical technique," implying their use was for validation of the technique and device performance, not necessarily for a consensus-driven "ground truth" establishment in the typical sense of diagnostic accuracy.

    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, an MRMC comparative effectiveness study was NOT done.
    • This device is a medical implant (spinal screw system), not an AI/software device that assists human readers. Therefore, the concept of "human readers improve with AI vs without AI assistance" does not apply to this submission.

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

    • No, a standalone (algorithm only) performance study was NOT done.
    • As explained above, this is a physical medical implant, not a software algorithm.

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

    For the non-clinical studies:

    • Wetlab: "Performance by 3 experienced surgeons according to MUST MC surgical technique" implies the ground truth for surgical technique validation was established through expert application/observation and adherence to predefined protocols.
    • Geometrical Analysis: Ground truth was the geometric properties of approved and marketed implants used for comparison, and engineering specifications.
    • Mechanical Testing (ASTM F1717): Ground truth was defined by the requirements and methodologies of the ASTM F1717-18 standard and comparisons to the mechanical characteristics of the predicate device.
    • Pyrogenicity: Ground truth was established by standard biological assessment methods for endotoxins, validated against established limits.

    8. The sample size for the training set:

    • Not applicable. This device is a physical medical implant, not an AI/machine learning model that requires a training set.

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

    • Not applicable. (See point 8).

    Intended Use

    The Medacta Ligament Staple is intended for use in medial collateral ligament (MCL) and lateral collateral ligament (LCL) reconstruction.
    Reconstructive treatment of ruptured or damaged MCL and LCL.

    Device Description

    Medacta Ligament Staple is a single size (ø11 mm) extra cortical fixation device which is impacted on the Medial Collateral Ligament (MCL) or on the Lateral Ligament (LCL) for soft tissue to bone refixation by means of a dedicated impactor. The device consists of a circular plate with protruding tapered serrated legs, made of titanium alloy (Ti6A14V ELI according to ISO 5832-3 and ASTM F136), and a staple inlay, made of PEEK according to ASTM F2026, for pressing the graft down to the bone, featuring a lower spike patterned surface for increasing soft tissue fixation.

    AI/ML Overview

    The provided text describes a 510(k) premarket notification for a medical device called "Ligament Staple." This submission focuses on demonstrating substantial equivalence to a predicate device based on non-clinical performance data. It explicitly states that no clinical studies were conducted.

    Therefore, I cannot fulfill the request to describe acceptance criteria and a study that proves the device meets those criteria, as the information required for such a description (particularly human-in-the-loop performance, expert ground truth, and clinical efficacy/safety) is not present in the provided document.

    The document discusses "design validation" and "characterization testing" but these are within the scope of non-clinical testing (e.g., mechanical properties, biocompatibility, MRI safety). There is no mention of an algorithm, AI, or any form of diagnostic or assistive software that would require the typical acceptance criteria and study design described in your prompt (e.g., MRMC studies, standalone performance, human reader improvement).

    To explicitly address the points in your prompt given the inability to provide the direct information:

    1. A table of acceptance criteria and the reported device performance: Not applicable. The document details non-clinical tests and their adherence to standards (e.g., ASTM, ISO), but these aren't presented as "acceptance criteria" in the context of clinical performance or AI/software. For example, it mentions "Cyclic and load-to-failure properties" and "MR safety evaluation," implying mechanical and safety performance testing rather than diagnostic or AI performance.
    2. Sample sizes used for the test set and the data provenance: Not applicable. There's no "test set" in the sense of clinical images or patient data for an AI/diagnostic device. The "Ligament staple Porcine bone workshop" and "Ligament staple wetlab" suggest in-vitro or ex-vivo testing, but no specific sample sizes for these are provided.
    3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. As no clinical studies or human reader-based evaluations were performed, no experts were needed for establishing ground truth in this context.
    4. Adjudication method for the test set: Not applicable. No clinical or image-based test set was used that would require adjudication.
    5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done: No, explicitly stated "No clinical studies were conducted."
    6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done: Not applicable. This is a physical medical device (ligament staple), not an algorithm or software.
    7. The type of ground truth used: Not applicable in the context of AI/diagnostic performance. Ground truth would relate to the physical properties and performance of the device in non-clinical settings (e.g., mechanical load, material properties, biocompatibility results).
    8. The sample size for the training set: Not applicable. There is no AI/algorithm for which a training set would be required.
    9. How the ground truth for the training set was established: Not applicable for the same reason as above.
