## Intended Use

Joint replacement is indicated for patients suffering from disability due to: degenerative, post-traumatic or rheumatoid arthritis; avascular necrosis of the femoral condyle; post-traumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy; moderate valgus, varus or flexion deformities; treatment of fractures that are unmanageable using other techniques. This device may also be indicated in the salvage of previously failed surgical attempts. The device is intended for cemented applications.

## Device Story

Foundation Knee System, Foundation PS Knee System, and 3DKnee System are semi-constrained cemented knee prostheses. Modification involves adding a Titanium Nitride (TiNbN) coating to the entire surface of femoral components and removing porous coating from Foundation Knee Femoral Component. Device used by orthopedic surgeons in clinical settings for total knee arthroplasty. Prosthesis replaces damaged joint surfaces to restore function and reduce pain in patients with arthritis, necrosis, or deformity. Clinical benefit derived from improved wear resistance and surface properties provided by TiNbN coating while maintaining established design and surgical technique.

## Clinical Evidence

No clinical data provided. Substantial equivalence supported by bench testing including acute system toxicity, bone/muscle implantation studies, cytotoxicity, GC/MS fingerprinting, irritation, sensitization, and mechanical coating characterization (composition, thickness, hardness, adhesion, roughness, wear resistance).

## Technological Characteristics

Semi-constrained cemented knee prosthesis. Femoral components feature Titanium Nitride (TiNbN) surface coating. Porous coating removed from Foundation Knee Femoral Component. Materials, design, and sterilization methods remain consistent with predicate systems.

## Regulatory Identification

A knee joint patellofemorotibial polymer/metal/polymer semi-constrained cemented 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 includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and a tibial component or components and a retropatellar resurfacing component made of ultra-high molecular weight polyethylene. This generic type of device is limited to those prostheses intended for use with bone cement (§ 888.3027).
