Knee prosthesis with anteroposterior stabilisation

摘要

Knee prosthesis comprises U-shaped femoral prosthetic element (1), and tibial prosthetic element (2). Femoral element has bo (30) with latch pin (31) attaching to trochlea and having cell (32) from where convex projection (33) develops. Tibial element h protuberance defining boss (40) attached to concave sliding ramp (41). Convex projection is defined by transversal radius of curvature and sagittal curvature.
