Abstract
It is thought difficult to replace a severely damaged joint with a non-hinged surface replacement knee prosthesis. We performed Kinematic stabilizer knee replacement on 16 severely damaged knees in 10 patients displaying 30 degrees or more of flexion or -45 degrees or less of extension. It was necessary to use a modified surgical technique to perform surface knee replacement on such damaged knees. We detached the collateral ligaments of both sides, cut enough bone to realign the femur and the tibia and then sutured the collateral ligaments with correct alignment. Although there was not enough gain in range of motion, all patients were completely free of pain and had markedly increased walking ability after surgery.
