Abstract

The invention discloses a total knee joint replacement prosthesis, which comprises femoral condyle, tibial support, tibial pad and patella. Position column and glenoid, the glenoid defines the shape of the glenoid surface to match the articular surface of the femoral condyle, the lower end surface of the tibial pad is formed with a first groove and a second groove, and the tibial tray includes a support plate with a fixing member, The upper surface of the support plate has a first pillar and a second pillar locked with the tibial pad, and the patella includes a patella articular surface and a patella fixing post. The total knee replacement prosthesis of the present invention has good initial stability and long-term use stability, improves biocompatibility, is beneficial to bone metabolism, improves tibial support anti-subsidence, anti-rotational resistance and long-term use Stability, further improving the bonding force of the tibial support and the tibial pad, further prolonging the service life of the knee joint.

Description

technical field

[0001] The invention relates to a joint prosthesis, in particular to a total knee joint replacement prosthesis. Background technique

[0002] The knee joint is a joint with a large body, complex structure, and high requirements for motion function; artificial knee replacement is a surgical operation that removes the worn, diseased or damaged surface of the knee joint and replaces it with an artificial knee joint. In the case of surgery, the tibial tray is implanted in the patient's tibia, and then the tibial tray is fixed on the tibial tray, and the condylar surface of the patient's femoral condyle abuts on the tibial tray, which has become a commonly used operation in clinical practice, and in the treatment of Remarkable success has been achieved in knee joint disease.

[0003] The existing artificial knee prosthesis completely refers to the anatomical shape of the human knee joint, which mainly includes the femoral condyle prosthesis, the tibial tray prost...
