Abstract
A prosthesis for total knee replacement (TKR) includes: a femoral component having a pair of condylar-bearing surfaces (10,12), a tibial component having a tibial platform (22) with an upstanding abutment (18) located between the condylar-bearing surfaces, and a meniscal component (15) interposed between the condylar-bearing surface and the tibial platform for sliding movement in the anterior-posterior (A-P) direction. The femoral component has an intercondylar projecting surface (20) adapted to contact the upstanding abutment at high degrees of flexion so as to influence the sliding movement of the meniscal component in a posterior direction.
