摘要：
A bearing component (2) for a joint replacement prosthesis comprises a first bearing element (4)； a second bearing element (6), and a linking element (8), operatively connecting the first and second bearing elements (4, 6) and permitting relative motion there between. The flexible linking element (8) prevents dislocation of mobile bearings in a total knee replacement prosthesis. The invention also relates to a bridging element which retains the linking element 8 with some play, which acts as a ligament support (2051), and which causes a deflection of the line of action of a ligament (1018). A joint replacement prosthesis is also disclosed comprising a biasing element (1140) or a tensioning element (1220) operatively coupled to the artificial ligament (1018). The biasing element (1140) or tensioning element (1220) may be housed in the stem of a tibial tray (1006).
