Recently, the innovative product Additive Manufacturing Matching Knee Prosthesis of Naton Biotechnology (Beijing) Co., Ltd. is approved by China NMPA.

This product consists of a femoral condylar prosthesis, a tibial tray prosthesis, and a meniscus prosthesis. The femoral condylar prosthesis and tibial tray prosthesis is constructed from cobalt-chromium-molybdenum powder by laser additive manufacturing, while the meniscus prosthesis is constructed from ultra-high molecular weight polyethylene. Notably, this product adopts a personalized design of total knee prosthesis, featuring a bionic design of the joint surface that allows for the reconstruction of normal patellofemoral joint movement.

With its application in knee prosthesis replacement, in combination with bone cement, this product is tailored for patients with osteoarthritis and those in special needs. Moreover, it is capable of achieving satisfactory coverage on each osteotomy plane, effectively solving the problems of mismatch and over-coverage. The marketing of this product will provide a new treatment option for patients.

The NMPA will strengthen the post-marketing surveillance of the product to protect the safety of medical devices used by patients.
