The Progressive Orthopaedic Company Total Knee System II is indicated in knee arthroplasty for reduction or relief of pain and/or improved knee function in skeletally mature patients with severe knee pain and disability due to rheumatoid arthrius, osteoarthritis, primary and secondary traumatic arthritis, collagen disorders, avascular necrosis of the femoral condyle or pseudogout, posttraumatic loss of joint configuration, particularly when there is patellofemoral erosion, dysfunction or prior patellectomy, moderate valgus, varus, or flexion deformities. The Progressive Orthopaedic Company Total Knee System II may also be indicated in the salvage of previously failed surgical attempts if the knee can be satisfactorily balanced and stabilized at the time of surgery. The Progressive Orthopaedic Company Total Knee System II is designed for cemented use only.

The Progressive Orthopaedic Company Total Knee System II is a fixed bearing implant available in posteriorstabilized (PS) and cruciate-retaining (CR) configurations. It is a patellofemorotibial, polymer, semi-constrained, cemented knee prosthesis that consists of a femoral component, tibial tray and patellar component. The PS version has tibial inserts with posts and femoral components with cams that interact with the posts to help stabilize the knee after the posterior cruciate ligament is removed. The CR version of The Progressive Orthopaedic Company Total Knee System II has tibial inserts and femoral components without posts or cams, allowing the posterior cruciate ligament to be "retained" and provide stability to the knee joint. The femoral component articulates with the tibial insert component. The underside of the tibial insert component is flat and "snaps" into tibial baseplate component. The design and sizing of the femoral components correspond to the natural femoral anatomy, enhancing stress distribution and restoring original femoral dimensions and normal rotation, extension and flexion. Each femoral component has the same intercondylar distance and radius of curvature. Each tibial insert component is complimentarily shaped to conform to the femoral components. This allows any size femoral component to be matched with any size tibial component. The dome shape of each UHMWPE patellar component provides excellent contact with the femoral component and evenly distributes stresses. The dome shape of each patellar component also simplifies implantation by eliminating the need for rotational orientation.
