Patent ID: 11759322

Abstract:
The method of treating osteoarthritis of the knee includes replacing the entire cartilage of the femoral condyle, proximal tibia, and two menisci using allograft, while retaining the native cruciate ligaments. The method includes resection of the proximal tibia and the femoral condyle. A first allograft is configured to replace the femoral condyle and includes whole cartilage with about 5 mm to about 7 mm of cancellous bone attached. The first allograft can have a slot or opening through which native cruciate ligaments may pass. A second allograft can replace the upper end of the tibia and menisci. The second allograft can include a slot or opening through which native cruciate ligaments may pass. The first and second allografts can be fixed using cancellous screws. The procedure can provide patients with full knee flexion, and thereby enable kneeling, e.g., as required in the Islamic prayers, full kneeling, or any other activity which requires full flexion of the knee and kneeling.
