AI Technical Summary
Technical Problem
Existing joint prostheses suffer from aseptic loosening and debris dispersion due to wear and tear during use, affecting their lifespan and stability.
Method used
Femoral condyle prostheses, tibial plateau prostheses, and tibial plateau pad prostheses made of zirconium-niobium alloy materials are manufactured using 3D printing technology to create trabecular bone structures. Metal-ceramic interfaces and microtextural structures are configured on the friction contact surfaces to eliminate polymer material components and reduce wear debris.
Benefits of technology
It reduces wear and debris, improves the wear resistance of the friction interface, enhances the stability and long service life of the prosthesis, and promotes osseointegration and prosthesis stability.

Abstract
The application relates to the technical field of orthopedic artificial joint, in particular to an integrated unicompartmental prosthesis system and a preparation method of the integrated unicompartmental prosthesis system. The integrated unicompartmental prosthesis system comprises a femoral condyle prosthesis, a tibial plateau prosthesis and a tibial plateau pad prosthesis; the femoral condyle prosthesis and the tibial plateau prosthesis are both made of a zirconium niobium alloy 3D printing; the tibial plateau pad prosthesis is made of a zirconium niobium alloy 3D printing or a zirconium niobium alloy forging; the upper surface of the femoral condyle prosthesis is in contact with the tibial plateau pad prosthesis, and the upper surface of the tibial plateau prosthesis is in contact with the lower surface of the tibial plateau pad prosthesis. The bone integration interfaces of the integrated unicompartmental prosthesis system are all formed by zirconium niobium alloy trabecular structures, and the friction contact surfaces between the prostheses are all metal ceramic interfaces formed by zirconium niobium surface oxidation, so that the bone resection amount of the tibial plateau can be reduced, the wear resistance of the friction interface can be improved, the wear debris of the friction interface can be greatly reduced, and the stability of the prosthesis in the later period is improved.
