Men and Women With Different Designs and Semi-individual Total Knee Replacement

This study aims to evaluate the effectiveness of femoral condyle prosthesis, tibial tray prosthesis and meniscus prosthesis of semi-individualized total knee replacement prostheses designed with gender differences; and compare and analyze with the current classic prostheses, showing gender differences. The designed semi-personalized total knee replacement prosthesis lays the foundation for clinical application, including: 1. Compared with the classic osteotomy method, compare whether the semi-individualized total knee arthroplasty with a gender-specific design has advantages and better safety in the osteotomy method. 2. To evaluate the difference between the amount of osteotomy in the semi-individualized total knee arthroplasty designed for gender differences and the amount of classic osteotomy. 3. Compared with classic prostheses in the market, verify the clinical effects of semi-individualized total knee replacement prostheses designed for gender differences, and provide a basis for their clinical promotion and application.
