The Arthrex PushLock Suture Anchor is a two piece "push-in" suture anchor device comprised of a polyetheretherketone (PEEK) anchor body with a polyetheretherketone (PEEK) eyelet pre-loaded on a disposable inserter. The anchors are threaded and range from 2.0 mm to 4.5 mm in diameter and 8.6 mm to approximately 24 mm in length. The device is sold sterile and is single-use.

The Arthrex Self-Punching PushLock Suture Anchor is a "push-in" suture anchor comprised of a polyetheretherketone (PEEK) anchor body with a polyetheretherketone (PEEK) eyelet pre-loaded on a disposable inserter. The anchor body is fully threaded and barbed. The anchor is 3.5 mm in diameter and 19.8 mm in length. The device is sold sterile and is single-use.

The provided FDA 510(k) clearance letter describes a medical device, the Arthrex PushLock Suture Anchors, and its substantial equivalence to predicate devices, rather than a study proving the device meets performance criteria for an AI/CADe device. Therefore, much of the requested information regarding acceptance criteria, study design, and ground truth for an AI/CADe system cannot be extracted directly from this document.

However, I can extract information related to the device itself and the types of performance testing conducted to demonstrate its safety and effectiveness relative to its predicates.

Here's a breakdown of the available information based on your request, with an emphasis on what can be extracted and what cannot from this specific document:

Device Name: Arthrex PushLock Suture Anchors
K Number: K251145

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

This document does not specify quantitative acceptance criteria or detailed reported performance values for an AI/CADe system. Instead, it focuses on demonstrating substantial equivalence to predicate devices for a physical orthopedic implant. The performance data mentioned are general categories of testing for such devices.

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 510(k) clearance letter. The document mentions "product functionality... sterilization validation, biological safety evaluation and temperature study testing," but does not detail the sample sizes for these tests, nor their provenance in terms of patient data. These tests are typically conducted on the physical device itself or its materials, not on clinical datasets in the way an AI/CADe study would use.

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 applicable and not provided. This clearance is for a physical medical device (suture anchor), not an AI/CADe system that requires expert interpretation for ground truth establishment.

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

This information is not applicable and not provided for the reasons stated above.

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

This information is not applicable and not provided. An MRMC study is relevant to AI/CADe systems, not a physical implant like a suture anchor.

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

This information is not applicable and not provided.

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

This information is not applicable in the context of an AI/CADe device's ground truth. For the Arthrex PushLock Suture Anchors, "ground truth" would relate to its physical properties, biocompatibility, and mechanical performance, which are evaluated through standardized test methods (e.g., ASTM standards) rather than expert consensus on clinical data or pathology reports. The document mentions "product functionality," "biological safety evaluation," and "sterilization validation," implying the use of established scientific and engineering principles for evaluation.

8. The sample size for the training set

This information is not applicable and not provided. There is no AI/CADe system being trained with clinical data.

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

This information is not applicable and not provided.

Summary of what the document does convey about the study (testing) conducted:

The submission aimed to obtain FDA clearance for the Arthrex PushLock Suture Anchors, sterilized using the Arthrex X-ray radiation sterilization process. The core of the "study" for this type of device is demonstrating substantial equivalence to existing legally marketed predicate devices.

The performance data supplied consisted of:

• Product functionality (including accelerated aging)
• Product induced radiation
• Sterilization validation
• Biological safety evaluation
• Temperature study testing

These tests compared the subject device to several predicate and reference devices, confirming that the new device, particularly with its new sterilization process, performs equivalently in terms of safety and effectiveness. The conclusion states that "Any differences between the Arthrex PushLock Suture Anchors and the predicate devices are considered minor and do not raise different questions of safety or effectiveness."
