The Arthrex Knotless SutureTak Anchor is a non-absorbable, "tap-in" suture anchor with a ribbed profile and a proximally placed external suture eyelet. The anchor is manufactured of Polyetheretherketone (PEEK) and is preloaded with Arthrex Suture and is offered preassembled on a driver. The anchor was originally cleared under K120155 for indications in the foot, ankle, knee, hand, wrist, elbow, shoulder, and hip.

This document describes the Arthrex Knotless SutureTak Anchor, a medical device. Here's an analysis of its acceptance criteria and the supporting study:

1. Table of Acceptance Criteria and Reported Device Performance

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

The document does not explicitly state the sample size used for the pull-out test.
The provenance of the data (country of origin, retrospective/prospective) is also not specified. It is an in-vitro performance test.

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

This information is not applicable. The study involves performance testing of the device's mechanical and biological properties, not a diagnostic or AI-driven evaluation that requires expert ground truth assessment.

4. Adjudication Method

This information is not applicable for this type of device performance study.

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

No. This is a medical device (suture anchor) and not an AI-driven diagnostic tool. Therefore, an MRMC study is not relevant.

6. Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study

No. This is a medical device, not an algorithm.

7. Type of Ground Truth Used

For the pull-out test, the "ground truth" is established by the performance of the chosen predicate device (DePUY Mitek VERSALOK Anchor), against which the Arthrex Knotless SutureTak Anchor is compared for statistical equivalence.

For the pyrogenicity test, the "ground truth" is defined by the pyrogen limit specifications outlined in EP 2.6.14/USP <85>.

8. Sample Size for the Training Set

This information is not applicable. This is a medical device, not an AI model that requires a training set.

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

This information is not applicable as there is no training set for this device.
