The subject Liner is available in Standard, Lipped, and Lateralized/Face-changing configurations. The subject Liner has a two-part locking detail featuring 12 anti-rotational tabs and a lock flange, which is intended to mate with the 12 antirotational pockets and lock groove of the compatible Prime Acetabular Shells (K170444; K180798).

The provided document is a 510(k) Summary for a medical device (Prime E-CLASS™ XLPE Liner), which focuses on demonstrating substantial equivalence to predicate devices rather than providing a detailed study proving the device meets specific acceptance criteria with quantifiable performance metrics.

Therefore, the information required for a table of acceptance criteria and proven device performance as typically expected for a diagnostic AI/ML device is not available in this document. The document describes non-clinical testing performed to establish substantial equivalence for a physical implant, not a software algorithm.

Here's a breakdown of why the requested information cannot be fully provided based on the input text:

• Acceptance Criteria & Device Performance: The document does not define specific clinical or diagnostic acceptance criteria (e.g., sensitivity, specificity, accuracy thresholds) that the device must meet. Instead, it details non-clinical tests (bacterial endotoxin, mechanical testing, material properties, wear analysis, fatigue, range of motion) to show the device performs similarly to predicate devices. The "reported device performance" are the results of these non-clinical tests, which aim to demonstrate equivalence rather than meeting independent performance criteria.

• Study Type: This is a premarket notification (510(k)) for a physical medical implant, not a study of an AI/ML diagnostic or prognostic device. The "study" here refers to non-clinical bench testing and analysis to show equivalence.

Given the nature of the document, most of the requested fields are not applicable or the information is not present.

However, I can extract what is available regarding the "studies" (non-clinical testing) performed:

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

As mentioned, specific acceptance criteria in terms of clinical performance metrics are not provided. The "acceptance criteria" for this 510(k) submission are implied by successful completion of tests demonstrating substantial equivalence to predicate devices. The "reported device performance" refers to the outcomes of these non-clinical tests.

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: Not explicitly stated for each non-clinical test. For mechanical tests, standard testing protocols define sample sizes, but these are not enumerated here.
• Data Provenance: Not applicable. This refers to bench testing of physical components, not patient data.

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)

• Not applicable. Ground truth for clinical data is not relevant to this type of non-clinical device testing.

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

• Not applicable. Adjudication is typically for human assessment of images or clinical outcomes, not for mechanical bench testing.

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 applicable. This is not an AI/ML diagnostic device.

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

• Not applicable. This is not an AI/ML diagnostic device.

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

• For non-clinical testing, the "ground truth" is established by adherence to recognized national and international standards (ASTM, ISO, FDA Guidance) and laboratory measurements using calibrated equipment. For example, the ground truth for endotoxin levels is defined by the USP limit. For mechanical properties, it's the measured values compared to established benchmarks or predicate device performance.

8. The sample size for the training set

• Not applicable. This is not an AI/ML diagnostic device, and thus no "training set" of data in that context. The "training" for the device's design comes from engineering principles, material science, and prior designs.

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

• Not applicable. No "training set" in the context of AI/ML.

This looks like a 510(k) summary for a medical device (Prime Acetabular Cup System), which focuses on demonstrating substantial equivalence to a predicate device rather than presenting detailed clinical study results with acceptance criteria.

As such, it does not contain the specific information requested in your prompt regarding acceptance criteria, a study proving device meets acceptance criteria, sample sizes for test/training sets, data provenance, expert adjudication, MRMC studies, standalone performance, or ground truth establishment.

The document primarily provides:

• Device Description and Intended Use: Details the components of the Prime Acetabular Cup System (Acetabular Shells, Liners, Bone Screws) and their intended applications in total hip arthroplasty.
• Substantial Equivalence Justification: States that the device is substantially equivalent to predicate devices (PROCOTYL® PRIME Acetabular Cup System, K170444) based on identical indications for use, similar materials (for the liner, drawing on K052026), and unchanged design features for shells and screws since K170444.
• Nonclinical Testing: Lists bench tests performed on the subject device (liner push-out, lever-out, torque-out per ASTM F1820, ASTM STP1301) and references tests performed on the predicate device and deemed applicable (deformation, frictional torque, wear, fatigue, range of motion, screw properties).
• Clinical Testing: Explicitly states that clinical data was not provided for the subject devices.
• Biocompatibility: Justifies not performing specific biocompatibility tests on the subject implants as their materials and patient contact are identical to predicate devices.
• Compatibility Tables: Details compatibility with other MicroPort Orthopedics products.
• Sterilization Residuals: Discusses previous evaluations and current applicability.

Therefore, I cannot populate the requested table and answer your questions directly from the provided text. The document does not describe a study with acceptance criteria in the context of clinical performance or diagnostic accuracy, which is implied by your prompt's questions. It focuses on engineering and material equivalence testing for an orthopedic implant.

This document is a 510(k) summary for the PROCOTYL® PRIME Acetabular Cup System, a medical device for total hip arthroplasty. It describes the device, its intended use, and argues for its substantial equivalence to previously cleared predicate devices.

Here's an analysis of the provided text in relation to your request about acceptance criteria and studies:

Crucially, this document is a 510(k) Pre-Market Notification, which is a regulatory submission to demonstrate that a new device is substantially equivalent to a legally marketed predicate device. It is not a detailed clinical study report or a publication presenting performance metrics against specific acceptance criteria for an AI/ML device.

Therefore, most of the information you are requesting about acceptance criteria, specific performance metrics, sample sizes for test sets, expert ground truth, MRMC studies, or standalone algorithm performance for an AI/ML device is not present in this document. This document concerns a physical orthopedic implant.

However, I can extract the information that is available and clarify what is missing based on your request.

Summary of Device Acceptance Criteria and Performance (Based on available information):

Missing Information (as per your request, because this is not an AI/ML device nor a typical clinical study report):

1. Sample size used for the test set and the data provenance: Not applicable. The "test set" here refers to physical components tested in a lab, not a diagnostic dataset. The document does not specify sample sizes (e.g., number of cups, liners, or screws) for any of the nonclinical tests. Data provenance, in the sense of country of origin or retrospective/prospective for patient data, is also not applicable here.
2. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for an orthopedic implant's mechanical properties is typically established through recognized engineering standards (e.g., ASTM) and validated testing methodologies, not expert medical consensus on diagnostic images.
3. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable. This applies to human review of diagnostic outputs, not mechanical testing.
4. 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 applicable. This is not an AI/ML diagnostic device with human-in-the-loop.
5. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This is not an AI/ML algorithm.
6. The type of ground truth used (expert consensus, pathology, outcomes data, etc): For mechanical testing, the "ground truth" is defined by the specifications and performance standards (e.g., ASTM standards) that the device must meet. For biocompatibility, it's defined by the pyrogen limit specification (≤ 20 EU/device). It's not based on expert consensus, pathology, or outcomes data in the conventional sense used for diagnostic devices.
7. The sample size for the training set: Not applicable. This is not an AI/ML device that requires a training set.
8. How the ground truth for the training set was established: Not applicable.

The DYNASTY® Acetabular System with Ceramic contains femoral heads in size 28mm manufactured from alumina matrix composite, mating acetabular liners manufactured from crosslinked polyethylene, and beaded acetabular shells manufactured from titanium alloy.

The provided 510(k) summary for the DYNASTY® Acetabular System with Ceramic does not contain information related to acceptance criteria for a device, nor does it describe a study that proves the device meets specific acceptance criteria in the manner typically associated with AI/software devices.

Instead, this document describes a traditional medical device (an orthopedic implant) and focuses on demonstrating substantial equivalence to previously cleared predicate devices. The "study" mentioned is purely for mechanical and tribological (wear) evaluation, not clinical or performance criteria as would be relevant for software or AI.

Therefore, I cannot extract the requested information in the format provided because it's not present in the document.

Here's why and what the document does provide:

• Type of Device: The DYNASTY® Acetabular System with Ceramic is a physical orthopedic implant (acetabular shell, liner, and femoral head for total hip replacement). It is not a software device or an AI algorithm.
• Regulatory Pathway: This is a 510(k) premarket notification, which seeks to demonstrate substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through extensive clinical trials as for a PMA.
• "Acceptance Criteria" in this context: For a physical implant like this, "acceptance criteria" relate to engineering specifications, material properties, biocompatibility, mechanical strength, wear resistance, and manufacturing quality. These are typically assessed through bench testing and adherence to recognized standards.
• "Study" in this context: The "study" mentioned is non-clinical mechanical and tribological testing.

Specific answers based on the provided text, explaining why other points are not applicable:

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

   • Not Applicable. The document does not provide a table of acceptance criteria or performance metrics in the way one would for a software or AI device (e.g., sensitivity, specificity, AUC). It discusses mechanical and tribological evaluations and comparisons to predicate devices rather than specific performance targets against clinical gold standards.

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

   • Not Applicable. This refers to mechanical testing, not a clinical study involving a test set of data. The "subject size 28mm ceramic head was used as a worst case" for burst, post-fatigue burst, rotational stability, and pull-off force testing, implying a limited number of physical samples (likely one or a few) were subjected to these mechanical tests. No patient data or clinical retrospective/prospective studies were conducted.

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):

   • Not Applicable. This device is not a diagnostic or AI tool requiring expert ground truth for a test set.

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

   • Not Applicable. This is not a clinical study requiring adjudication of expert opinions.

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 Applicable. This is a physical medical device, not an AI system.

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

   • Not Applicable. This is a physical medical device, not an AI algorithm.

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

   • Not Applicable. For mechanical testing, the "ground truth" would be the physical properties derived from standardized test methods (e.g., force measured at failure, wear volume). The document states:
     • "The subject DYNASTY® Acetabular System with Ceramic was evaluated mechanically and tribologically."
     • "The mechanical testing on the subject and predicate devices was performed on wrought Cobalt Chrome modular neck spigots cleared under K091423 and K100866."
     • "The subject size 28mm ceramic head was used as a worst case in burst, post-fatigue burst, rotational stability, and pull off force testing."
     • "Wear testing compared the subject size 28mm femoral heads to the K130376 DYNASTY® Acetabular System."
     • "Range of motion evaluation compared the subject system to the predicate K052026 in three planes."
     • This implies physical engineering measurements as the "ground truth" for evaluating the device's mechanical characteristics.

8. The sample size for the training set:

   • Not Applicable. This is not an AI/ML device requiring a training set.

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

   • Not Applicable. This is not an AI/ML device requiring a training set.

In summary, the provided document describes a "Traditional 510(k)" pathway for a physical orthopedic implant. The demonstration of safety and effectiveness relies on substantial equivalence to predicate devices and non-clinical bench testing, not clinical studies or performance criteria typically associated with software/AI medical devices.

1. non-inflammatory degenerative joint disease such as osteoarthritis, avascular necrosis, ankylosis, protrusio acetabuli, and painful hip dysplasia;
2. inflammatory degenerative joint disease such as rheumatoid arthritis;
3. correction of functional deformity; and,
4. revision procedures where other treatments or devices have failed

The DYNASTY® Acetabular System with Ceramic is manufactured from alumina matrix composite. The components are offered in sizes ranging from 32mm to 40mm.

The provided text describes a 510(k) summary for the DYNASTY® Acetabular System with Ceramic, focusing on its substantial equivalence to predicate devices. It does not contain information about acceptance criteria or a study proving the device meets specific performance criteria related to an AI/ML algorithm.

Therefore, I cannot provide the requested information in the format of a table describing acceptance criteria and device performance for an AI/ML device, nor can I answer questions regarding sample sizes, ground truth establishment, expert qualifications, or MRMC studies.

The document states:

• "Clinical data was not provided for the subject devices." This explicitly indicates that no clinical study was performed to assess the device's performance in humans.
• "The subject DYNASTY® Acetabular System with Ceramic was evaluated mechanically, tribologically, and chemically." This suggests non-clinical (laboratory) testing was conducted, but the details of acceptance criteria for these tests and their results are not provided in a summary format. The document mentions that the testing "shows that it can be concluded that the subject ceramic material can be expected to perform well under normal physiological chemical and mechanical conditions," implying the tests were successful in demonstrating performance without specifying the criteria or results.
• The entire submission hinges on "Substantial Equivalence Information" to predicate devices. This means the device is considered safe and effective because it is very similar to devices already cleared by the FDA, rather than proving its effectiveness through new clinical trials against specific performance criteria.

In summary, the provided text does not contain the information needed to answer your questions regarding acceptance criteria and performance studies for an AI/ML device.
