Trabecular Metal Knee System Augments are intended for use where severe degeneration, trauma, or other pathology of the knee joint indicates total knee arthroplasty. When used with the NexGen Complete Knee Solution - Rotating Hinge Knee (RHK) System, the Trabecular Metal Augments are for cemented use only. When used with the NexGen Complete Knee Solution - Legacy Constrained Condylar Knee System, the Trabecular Metal Augments are for cementless or cemented use.
The Trabecular Metal Knee System Augments are manufactured to be compatible for use with Zimmer's NexGen Complete Knee Solution - Rotating Hinge Knee (RHK) System and Zimmer's NexGen Complete Knee Solution - Legacy Knee Constrained Condylar Knee (LCCK) System. When used with the RHK System, the Trabecular Metal Augments are for cemented use only. When used with the LCCK System, the Trabecular Metal Augments are for either cementless or cemented use.
This document is a 510(k) summary for a medical device (Trabecular Metal Knee System Augments) and explicitly states that no new performance data or studies were conducted for this submission:
- "The predicate and subject devices are identical; performance Performance Data: characteristics therefore remain as documented in the predicate submission (K024161)."
Because of this statement, it is not possible to provide the requested information regarding acceptance criteria and a study proving the device meets them from the provided text. The submission relies entirely on the performance established for its predicate device (K024161).
Therefore, the following information cannot be extracted:
- A table of acceptance criteria and the reported device performance: Not provided as no new studies were performed.
- Sample sized used for the test set and the data provenance: Not applicable as no new studies were performed.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable as no new studies were performed.
- Adjudication method for the test set: Not applicable as no new studies were performed.
- 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 device is a physical knee implant augment, not an AI software device involving human readers.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This device is a physical knee implant augment, not an algorithm.
- The type of ground truth used: Not applicable as no new studies were performed.
- The sample size for the training set: Not applicable as no new studies were performed, and this is a physical device, not a software algorithm.
- How the ground truth for the training set was established: Not applicable as no new studies were performed, and this is a physical device, not a software algorithm.

Dear Ms. Halevi:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

§ 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.
