ABSTRACT:
The invention concerns prosthetic knee joint devices, in particular of the meniscal type having femoral, tibial and meniscal components co-operable to allow congruence of the interfacing articulation surfaces while allowing close simulation of the natural joint in flexion-extension. The device features meniscal and tibial components each of one-piece bicompartmental construction having a pair of mutually spaced portions respectively defining condylar articulation surfaces, such portions being joined by way of an intercondylar portion, and the tibial and meniscal intercondylar portions being interengageable by means of complementary elements of a rib-and-groove joint arranged substantially in the antero-posterior direction, both the rib and the groove having curved side faces to allow limited long axis rotation between the components, and the groove being open at at least one end. With appropriate dimensioning, the device allows movement of the meniscal component in the antero-posterior direction, limited movement in the medio-lateral direction and limited long-axis rotation. It also provides in a simple and effective manner a securement against tibio-meniscal dislocation.
