Indicated for patients requiring total knee arthroplasty due to painful, disabling joint disease (osteoarthritis, traumatic arthritis, avascular necrosis, rheumatoid arthritis), post-traumatic loss of function, moderate varus/valgus/flexion deformity, revision of failed knee replacement, or distal femur/proximal tibia fractures. PS/PS+ components indicated for ligamentous instability, absent posterior cruciate ligament, or severe anteroposterior instability.

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).
