摘要:
A hinged knee prosthesis (10) comprises a tibial component (16) and a femoralcomponent (14). The tibial component (16) is configured to attach to a tibia.The tibial component has a bearing surface (128). The femoral component (14)is configured to hingedly attach to the tibial component (16) and rotate relativeto the tibial component (16). The femoral component (14) comprises a medial condyle(30) and a lateral condyle (32). The medial and lateral condyles (30 and 32) havean eccentric sagittal curvature surface (50) configured to rotate and translateon the bearing surface (128) of the tibial component (16). A method of rotatinga hinged knee (10) through a range of flexion is provided. The method fixedly attachesa femoral component (14) to a tibial component (16). Axial rotation of the femoralcomponent (14) is induced relative to the tibial component (16) when the hingedknee (10) is flexed.
