AI/ML Overview

Here's an analysis of the provided text regarding the acceptance criteria and study for the Regenerex™ Tibial Components:

1. Table of Acceptance Criteria and Reported Device Performance

Based on the provided text, the submission is a 510(k) for substantial equivalence, not a de novo submission presenting novel acceptance criteria. Therefore, the "acceptance criteria" are implicitly met by demonstrating substantial equivalence to predicate devices. The performance is assessed against the established safety and effectiveness of the predicates.

Acceptance Criteria (Implicit for 510(k))Reported Device Performance
Substantial Equivalence to Predicate Devices (in terms of safety and effectiveness)Claimed: "The technological characteristics (material, design and sizing) of the Regenerex™ Tibial Components are similar or identical to the predicate devices." Demonstrated via: Non-clinical laboratory testing. Result: "The results indicated that the device was functional within its intended use."
Functional within Intended Use"The results indicated that the device was functional within its intended use."

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

  • Sample Size for Test Set: Not applicable in the context of this 510(k) summary. The submission relies on non-clinical (laboratory) testing for "substantial equivalence" rather than a clinical "test set" from patients.
  • Data Provenance: Not applicable, as no human clinical data (prospective or retrospective) from specific countries are mentioned for evaluation of the device's performance.

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

Not applicable. No clinical test set with ground truth established by experts is described. The evaluation was primarily non-clinical.

4. Adjudication Method for the Test Set

Not applicable. No clinical test set requiring expert adjudication is described.

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

No. The document explicitly states: "Clinical Testing: None provided as a basis for substantial equivalence." Therefore, no MRMC study was conducted, and no effect size for human readers with/without AI assistance can be determined.

6. Standalone Performance Study (Algorithm Only)

Not applicable. The device described (Regenerex™ Tibial Components) is a medical implant, not an AI algorithm. There's no mention of an algorithm or standalone performance testing for AI. The "non-clinical testing" mentioned refers to laboratory tests on the physical implant.

7. Type of Ground Truth Used

The concept of "ground truth" as typically applied to diagnostic or AI systems is not directly relevant here. For a physical implant, "ground truth" would be inherent in the physical and mechanical properties demonstrated through laboratory testing (e.g., material strength, wear resistance, dimensional accuracy) against established industry standards or predicate device specifications. The document implies performance was compared against the "intended use" and "predicate devices."

8. Sample Size for the Training Set

Not applicable. This is not an AI/machine learning device; therefore, there is no "training set."

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

Not applicable, as there is no "training set."

§ 888.3565 Knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis.

(a)
Identification. A knee joint patellofemorotibial metal/polymer porous-coated uncemented prosthesis is a device intended to be implanted to replace a knee joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device is designed to achieve biological fixation to bone without the use of bone cement. This identification includes fixed-bearing knee prostheses where the ultra high molecular weight polyethylene tibial bearing is rigidly secured to the metal tibial base plate.(b)
Classification. Class II (special controls). The special control is FDA's guidance: “Class II Special Controls Guidance Document: Knee Joint Patellofemorotibial and Femorotibial Metal/Polymer Porous-Coated Uncemented Prostheses; Guidance for Industry and FDA.” See § 888.1 for the availability of this guidance.
