Prosthetic knee joint devices

摘要

In or for a prosthetic knee joint device involving a femoral component having a convexly curved articulation surface, a tibial component (10) having a relatively flattened articulation surface (14), and a meniscal component (20) having two articulation surfaces (21,22) in back-to-back disposition and respectively substantially complementary to, and for mutual engagement with, the femoral and tibial component articulation surfaces: an assembly of tibial and meniscal components including means (30) separably connectable with the tibial component at least partially to bridge the meniscal component to retain their mutual articulatory engagement.
