<p>A prosthesis assembly for a knee comprising a femoral component (10) having two condylar surfaces (12) and an intercondylar notch (14), a meniscal component (20) having two condylar surfaces (22) and an upwardly extending intercondylar spine (24), and a tibial component (30) for supporting the meniscal component (20), wherein interengaging means (28a, 28b, 36a, 36b) are provided between the tibial and meniscal components (30, 20) such that limited rotational, anterior and posterior movement of the meniscal component (20) with respect to the tibial component (30) is allowed. The assembly retains the advantages of a posterior stabilised knee whilst more closely resembling the articulation of a natural healthy knee.</p> |
