Abstract

The invention belongs to the technical field of artificial bones, and particularly relates to a knee-joint prosthesis. The knee-joint prosthesis comprises a femoral condyle, a tibial plateau cushion and a tibial plateau support, and the upward angle of a front wing of the femoral condyle is seven degrees. According to the knee-joint prosthesis, when the upward angle of the front wing of the femoral condyle is implanted, a small thighbone can be elastically selected, implanting is more convenient and faster, and meanwhile, the situation that the implanted knee-joint prosthesis is embedded intoa supracondylar antero-lateral cortical bone is avoided; the knee-joint prosthesis is simple in structure, convenient to mount and good in stability, perfect fit between the plateau cushion and the plateau support and convenient mounting of the plateau cushion during an operation are ensured, the matching degree of covering of the plateau support and the bone surface of a cut tibia is further ensured, thus the implanted prosthesis is stable and firm, and abrasion is effectively reduced, and the service life of the knee-joint prosthesis is prolonged advantageously. The technical defects that inthe prior art, as for implanting of the knee-joint prosthesis, the structure is complex, mounting is inconvenient, and an implanted knee-joint prosthesis is low in flexion and poor in stability are overcome.

Description

technical field [0001] The invention belongs to the technical field of artificial bone, in particular to a knee joint prosthesis. Background technique [0002] The knee joint is the largest joint in the human body with complex anatomy and high requirements for motor function. Osteoarthritis and rheumatoid arthritis of the knee joint are the most common arthritis of the knee joint. In the late stage of arthritis, severe joint deformity and mobility impairment occur , then total knee resurfacing is required. Total knee arthroplasty can relieve joint pain, correct joint deformity, and restore joint mobility. At present, it has become the first choice for the treatment of knee joint diseases. It can effectively relieve knee joint pain after surgery, and can meet the requirements of patients for pain relief. [0003] Artificial total knee replacement is a kind of artificial joint replacement surgery. It refers to the removal of the articular surface that cannot be repaired by it...
