The Arthrex PushLock is a two piece "push-in" suture anchor device comprising a biodegradable anchor body manufactured from either PLLA or PLDLA/betaTCP with a polyetheretherketone (PEEK) eyelet pre-loaded on a disposable inserter. The anchor body ranges in diameter from 2.5mm to 2.9mm and 8mm to 15.5mm in length.

Here's a breakdown of the acceptance criteria and study information based on the provided document:

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 a sample size for a "test set" in the context of validating a device for its intended use or performance against a specific clinical outcome. The testing mentioned (inherent viscosity, peak load, bacterial endotoxin) is related to material properties and safety rather than a clinical performance test.

• Sample Size: Not explicitly stated for a "test set" in the traditional sense of clinical or performance validation. It refers to the number of units tested for material properties and shelf-life.
• Data Provenance: The testing was performed after four years on the shelf, indicating a controlled laboratory environment. No country of origin for the data is specified, but the submission is from Arthrex Inc. in Naples, Florida, USA, implying U.S. based testing or standards. The testing is retrospective in the sense that it evaluates the effects of storage over time.

3. Number of Experts Used to Establish Ground Truth and Qualifications

Not applicable. This device is a surgical implant (suture anchor), and the submitted data pertains to material properties, shelf-life, and biocompatibility, not a diagnostic or AI-driven device requiring expert-established ground truth from images or clinical assessments.

4. Adjudication Method for the Test Set

Not applicable. There was no "test set" in the context of diagnostic performance requiring adjudication.

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

No. This is a surgical implant, not a diagnostic device that would typically undergo an MRMC study.

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

Not applicable. This is a surgical implant, not a software algorithm.

7. The Type of Ground Truth Used

The "ground truth" for the tests performed relates to:

• Material Specifications: Established limits for inherent viscosity and minimum peak load for the biodegradable materials (PLLA, PLDLA/βTCP) to ensure structural integrity and proper degradation over time.
• Regulatory Standards: Pyrogen limit specifications as defined by EP 2.6.14/USP <85> for bacterial endotoxin.

8. The Sample Size for the Training Set

Not applicable. This is a physical medical device, not a machine learning model, so there is no "training set."

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

Not applicable. There is no training set for this type of device.
