Just Medical Devices Announces Market Launch of the Biotype Knee Prosthesis System in China
Just Medical Devices (Tianjin) Co., Ltd., has announced the official market approval and launch of its groundbreaking Biotype Knee Prosthesis System. This product received official approval on July 30, 2025, from the National Medical Products Administration (NMPA) through the Special Review Procedure for Innovative Medical Devices (Green Channel). The Biotype Knee Prosthesis System is the first non-cemented knee prosthesis in China to use 3D-printed zonal trabecular bone technology, addressing a significant gap in the China’s high-end biotype knee market.
Key Technological Highlights
Globally Leading 3D Printing Technology
The Biotype Knee Prosthesis System is manufactured using electron beam melting (EBM) additive manufacturing to create a one-piece integral form. This design incorporates a zonal trabecular bone structure on both the femoral condyle and tibial plateau. This innovative structure significantly improves the rate of bone ingrowth and ensures long-term stability, with clinical data showing a 100% implant survival rate at a 5-year follow-up according to the manufacturer.
Self-Pressurizing Mechanical Stability Structure
The system features an innovative “penetrating claw” design that provides superior initial stability. This design helps to reduce the risk of postoperative loosening, a common complication with traditional biotype knees.
Elimination of Bone Cement-Related Complications
By eliminating the need for bone cement, the Biotype Knee Prosthesis System mitigates risks associated with bone cement toxicity, allergic reactions, and thermal damage. Clinical data from post-operative follow-ups show a 100% excellent/good rating after 7 days, with a 95.3% excellence rate on the HSS score according to the manufacturer.
