The components are designed for use in primary and revision surgery, where the posterior cruciate ligament and one or both of the collateral ligaments (i.e. medial collateral and/or lateral collateral ligament) are absent or incompetent. The Revision Knee Components are for single use only and are intended for implantation with bone cement. ## Device Story Revision Knee System consists of femoral components, tibial components, angled/offset couplers, stem extensions, and wedges. Designed for primary and revision knee arthroplasty in patients with ligamentous instability (absent/incompetent posterior cruciate and collateral ligaments). Implanted by orthopedic surgeons in clinical/hospital settings using bone cement. System provides structural replacement for damaged knee joints; restores joint function and stability. Single-use device. ## Clinical Evidence No clinical data provided; substantial equivalence is based on design and material similarity to legally marketed predicate devices. ## Technological Characteristics System includes femoral and tibial components, couplers, stems, and wedges. Materials are consistent with previously cleared Genesis II and Revision Knee System components (metal/polymer). Designed for cemented implantation. No electronic or software components. ## 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 - Smith & Nephew Revision Knee System ([K041106](/device/K041106.md)) - Smith & Nephew Genesis II Total Knee System ([K951987](/device/K951987.md)) - Smith & Nephew Genesis II Total Knee System ([K953274](/device/K953274.md)) - Smith & Nephew Genesis II Total Knee System ([K962137](/device/K962137.md)) ## Reference Devices - Zimmer Legacy Constrained Condylar Knee (L-CCK) - Biomet Oncology Salvage System (OSS) - Sulzer Orthopedics MOST System ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
