Abstract
A condylar total knee replacement prosthesis is disclosed having interacting guide surfaces for control of anterior-posterior displacement. The prosthesis comprises a femoral component (,) having a pair of condylar surfaces (,), a tibial component having a tibial platform (,) and a bearing component interposed between the femoral and tibial components. A femoral guide surface (,) is located between the condyles and engages with a tibial guide surface (,) to cause the femoral component to displace posteriorly during flexing movements and displace anteriorly during extending movements. The femoral guide surface is offset posteriorly and downwardly from the center of major curvature of the femoral condyles.
