Abstract
A prosthetic knee implant system includes a prosthetic femoral component and a prosthetic tibial component. The femoral component includes a lateral condyle, a medial condyle, a bone-contacting surface that may be formed of porous metal, and an articular surface that may be formed of PAEK/PEEK. The tibial component includes medial and lateral condylar portions, a bone-contacting surface that may be formed of porous metal, and a second surface opposite the bone-contacting surface. Recesses extend a depth into the second surfaces of the medial and lateral condylar portions. Medial and lateral bearing inserts with flat proximal faces are positioned with the recesses of the medial and lateral condylar portions. Flexible medial and lateral meniscal components are positioned to surround the medial and lateral inserts, respectively, and extend proximal to the second surface of the insert.
