MOBILE/FIXED PROSTHETIC KNEE SYSTEMS

摘要

A prosthetic knee system includes a tibial tray (4802), a non-rotating tibial insert, and a rotating tibial insert. The non- rotating tibial insert and the rotating tibial insert are selectively coupleable to the tibial tray such that a fixed or a mobile orthopaedic prosthesis may be configured. In some embodiments, the tibial tray may be a fixed or mobile tibial tray. Additionally, in some embodiments, the prosthetic knee system may include a femoral component. The tibial tray includes a platform (4806) having a guide track (4812) extending downwardly from the bottom surface (4810). A stem (4804) is coupled to the tibial tray via a mounting end (4824) received in the guide track.
