摘要:
A bicondylar knee implants with improved fixation means for resurfacing only the weight-bearing surface of the femoral medial and lateral condyles, while preserving the cruciate ligaments and avoids displacing the patella. The inventive device includes metallic convex articular surfaces for resurfacing the medial and lateral femoral condyles, and concave multifacial non-articular surfaces to be affixed to the resected distal surfaces of the femur. The prosthesis provides claws situated at the anterior and posterior ends of the medial and lateral metallic condyles, which will firmly attach the implant against the resected femoral condyle. The prosthesis is designed to be implanted through a direct lateral approach and does not resurface the femoropatellar joint. Furthermore, a minirobot or electromechanical actuator is used to perform the femoral and tibial bone cuts using electromagnetic bone chipper.
