Intended Use

Trabecular Metal Tibial Cone Augments and Trabecular Metal Femoral Cone 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 Tibial Cone Augments and Trabecular Metal Femoral Cone Augments are for cemented use only. When used with the NexGen Complete Knee Solution - Legacy Constrained Condylar Knee System, the Trabecular Metal Tibial Cone Augments and Trabecular Metal Femoral Cone Augments are for cementless or cemented use.

Device Story

Trabecular Metal Tibial and Femoral Cone Augments are orthopedic implants designed to address bone loss during total knee arthroplasty. These augments are used in conjunction with Zimmer's NexGen Complete Knee Solution, specifically the Rotating Hinge Knee (RHK) System or the Legacy Constrained Condylar Knee (LCCK) System. When paired with the RHK system, the augments are restricted to cemented use; when paired with the LCCK system, they may be used with or without cement. The device provides structural support to the knee joint, aiding in reconstruction for patients with severe joint pathology. Surgeons implant these components during knee replacement procedures to restore joint stability and function.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on the identical nature of the subject devices to the predicate devices, for which performance characteristics were previously established.

Technological Characteristics

Trabecular Metal (porous metal) construction. Designed for use as knee system augments. Compatible with NexGen RHK and LCCK systems. Cemented or cementless fixation depending on the specific knee system used.

Indications for Use

Indicated for patients requiring total knee arthroplasty due to severe degeneration, trauma, or other knee joint pathology.

Regulatory Classification

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.

Special Controls

*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.

510(K) Summary of Safety and Effectiveness - Continued...

Device Description: The Trabecular Metal Tibial Cone Augments and Trabecular Metal Femoral Cone Auaments 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 Cone Augments are for cemented use only. When used with the LCCK System, the Trabecular Metal Augments are for either cementless or cemented use.

Intended Use: Trabecular Metal Tibial Cone Augments and Trabecular Metal Femoral Cone 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 Tibial Cone Augments and Trabecular Metal Femoral Cone Augments are for cemented use only. When used with the NexGen Complete Knee Solution - Legacy Constrained Condylar Knee System, the Trabecular Metal Tibial Cone Augments and Trabecular Metal Femoral Cone Augments are for cementless or cemented use.

- Performance Data: The predicate and subject devices are identical; performance characteristics therefore remain as documented in the predicate submission (K031962 and K051756).

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.
