Rheumatoid arthritis. 2. Post-traumatic arthritis, osteoarthritis, or degenerative arthritis in older patients whose age, weight, and activity level are compatible with an adequate long-term result. 3. Failed osteotomies, unicompartmental replacement, or total knee replacement. 4. Posterior stabilized knee systems are designed for use in patients in primary and revision surgery, where the anterior and posterior cruciate ligaments are absent or incompetent and the collateral ligaments remain intact. The Genesis II Posterior Stabilized High Flexion Articular Insert is used with existing cemented femoral, tibial tray, and patellar components of the Genesis II Total Knee System cleared via K951987 and K953274. The Genesis II Posterior Stabilized High Flexion Articular Insert is for single use only. (Note: A second version of this statement exists for uncemented applications, specifying use with components cleared via K030612). ## Device Story Genesis II Posterior Stabilized High Flexion Articular Insert is a UHMWPE tibial component designed for use within the Genesis II Total Knee System. It enables increased flexion range for patients with appropriate anatomical capability. The device is intended for single use in primary or revision knee arthroplasty. It functions as part of a semi-constrained prosthesis, replacing damaged joint surfaces in patients with absent or incompetent cruciate ligaments. Surgeons implant the device in an operating room setting. The insert integrates with existing cemented or uncemented femoral, tibial tray, and patellar components. By providing a stable articulation surface, it restores joint function and mobility, potentially reducing pain and improving quality of life for patients with degenerative joint disease. ## Clinical Evidence Bench testing only. Mechanical test data demonstrated the device is equivalent to currently used clinical devices and capable of withstanding expected in vivo loading. ## Technological Characteristics Material: UHMWPE (Ultra-High Molecular Weight Polyethylene). Design: Posterior stabilized articular insert for semi-constrained knee prosthesis. Connectivity: None (mechanical component). Sterilization: Not specified. ## 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). ## Predicate Devices - Genesis II Total Knee System ([K951987](/device/K951987.md)) - Genesis II Total Knee System ([K953274](/device/K953274.md)) - Genesis II Total Knee System ([K030612](/device/K030612.md)) - Nexgen LPS Knee System ([K991581](/device/K991581.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
