Abstract

The invention provides a femoral condyle and a knee joint prosthesis with the same. The femoral condyle is arranged between a tibia and a femur and comprises a femoral condyle body arranged at the end, close to the tibia, of the femur and a fixing structure which is arranged on the side, in contact with the femur, of the femoral condyle body to make the femoral condyle body fixedly connected ontothe femur, wherein the fixing structure comprises a basal body and fixing teeth arranged on the basal body, and the fixing teeth can extend into the bone substance of the femur. According to the technical scheme, the problem is solved that in the prior art, a femoral condyle is likely to become loose and flake off.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a femoral condyle and a knee joint prosthesis having the same. Background technique [0002] Unicompartmental knee arthroplasty (UKA) has been used for more than 30 years in the treatment of unicompartmental tibiofemoral arthritis. Despite poor early reports, it has now been developed as a safe and reliable treatment. To ensure the curative effect of UKA, it is necessary to select appropriate cases, superb surgical skills, and avoid overcorrection of deformities. This approach is suitable for patients with localized pain, good range of motion, and solitary tibiofemoral arthritis on imaging. Compared with total knee arthroplasty, UKA has greater range of motion, higher patient satisfaction, and comparable mid-term prosthetic survival. [0003] As a surgical implant, the unicondylar knee joint also faces the problem of prosthesis fixation. Good fixation can achieve early, medi...
