This prosthesis may be used for the following conditions, as appropriate: Non-inflammatory degenerative joint disease, including osteoarthritis and avascular necrosis; Rheumatoid arthritis; Correction of functional deformity; Revision procedures where other treatments or devices have failed; The porous coated femoral component may be used cemented or uncemented (biological fixation). All other femoral, tibial baseplate and patellar components are indicated for cemented use only. The Apex Knee™ Modular Tibia System Tibial Augments are intended to be bolted to the Tibia baseplate and cemented to the prepared tibia. ## Device Story Apex PS Knee System PS-C Insert is a modular component for total knee replacement; functions as part of a patellofemorotibial prosthesis. Device features a posterior stabilized (PS) design with a post approximately 1 mm larger than the predicate (K102578) to provide increased varus/valgus and internal/external rotational constraint. Used in orthopedic surgery by surgeons to restore joint function. Implanted in patients with degenerative joint disease or rheumatoid arthritis. Provides mechanical stability to the knee joint through geometric constraint. Benefits include improved joint stability and range of motion compared to standard inserts. System includes femoral components, tibial baseplates, patellar components, and modular tibial augments. Porous-coated femoral components allow for biological fixation; other components require cement. ## Clinical Evidence No clinical studies were performed. Substantial equivalence is supported by bench testing, including ROM evaluation per ASTM F2083-08 and tibio-femoral constraint testing per ASTM F1223-03. ## Technological Characteristics Patellofemorotibial metal/polymer semi-constrained prosthesis. Materials: Ultra-high molecular weight polyethylene (UHMWPE) per ASTM F648. Design: Modular tibial insert with increased post width (16-21 mm) for enhanced constraint. Sterilization: Ethylene oxide (SAL 10^-6). Packaging: Paper board box with double Tyvek inner pouch. ## 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 - Apex PS Knee System ([K102578](/device/K102578.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
