The subject device is intended to be used with cement knee constructs. This device is indicated for patients with severe knee pain and disability due to: - Rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis. - Collagen disorders, and/or 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. - The salvage of previously failed surgical attempts or for a knee in which satisfactory stability in flexion cannot be obtained at the time of surgery. This device is intended to be used with cemented knee constructs. ## Device Story Tapered stem extension for total knee arthroplasty (TKA); provides supplemental tibial baseplate support; shields fixation interfaces from stress by resisting bending and torsional moments. Implanted into intramedullary canal; used with cemented knee constructs. Device addresses severe knee pain/disability; aids in salvage of failed surgeries or cases requiring improved flexion stability. Surgeon-operated during orthopedic procedure. ## Clinical Evidence No clinical data provided. Bench testing only, including fatigue testing of the tibia keel and stem extension taper junction, static axial and torsional strength testing, and assessment of cortex perforation risk. ## Technological Characteristics Tapered stem extension for modular tibial baseplate. Metallic construction. Mechanically locked modular component. Designed for cemented fixation. Evaluated per FDA guidance for nonarticulating, mechanically locked modular implants and orthopedic implants with modified metallic surfaces. ## 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 - Persona Personalized Knee System ([K113369](/device/K113369.md)) - M-G II® Total Knee System Stemmed Tibial Baseplate Components ([K050723](/device/K050723.md)) - NexGen® Complete Knee Solution ([K933785](/device/K933785.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
