Intended Use
The indications for use of this femoral insert are noninflammatory degenerative joint disease including osteoarthritis or traumatic 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, rheumatoid arthritis, treatment of fractures that are unmanageable using other techniques.
Device Story
Femoral component for knee arthroplasty; articulates with Foundation® Knee System. Six sizes available. CoCr alloy (ASTM F75) base; plasma-sprayed commercially pure titanium surface for fixation; two smooth pegs for medial/lateral stability. Used by orthopedic surgeons in clinical/OR settings to replace damaged femoral condyles. Restores joint articulation and stability; addresses degenerative/traumatic joint conditions.
Clinical Evidence
Bench testing only.
Technological Characteristics
Material: CoCr alloy (ASTM F75) with plasma-sprayed commercially pure titanium coating. Design: Six sizes; two smooth pegs for stability. Semiconstrained cemented prosthesis.
Indications for Use
Indicated for patients with noninflammatory degenerative joint disease (osteoarthritis, traumatic arthritis), avascular necrosis of femoral condyle, post-traumatic joint configuration loss (with patellofemoral erosion/dysfunction/prior patellectomy), moderate valgus/varus/flexion deformities, rheumatoid arthritis, and fractures unmanageable by other techniques.
Regulatory Classification
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).
