MicroPort Orthopedics Granted Marketing Approval in China for Two Knee Systems

MicroPort Orthopedics received registration certificates from the National Medical Products Administration for two independently developed knee system products, SoSuperior+™ and MedalOne™.

Both knee systems inherit the design of MicroPort Orthopedics’ original Medial-Pivot knee, which has a 20-year record of clinical effectiveness, and the results of 17 years of clinical follow-up data show a 98% prosthesis survival rate and 95% patient satisfaction. The Medial-Pivot knee system requires no intercondylar osteotomy and provides improved joint motion and wear resistance on the basis of maximal bone retention. It helps restore the normal motion mechanics of the knee joint by simulating natural knee motion to maintain stability, resulting in a more natural and flexible postoperative motion mechanics and gait.

SoSuperior+ provides an intermediate model adding to the original products, which allows one femoral condyle type to be matched with four different tibial types, supporting selection of the prosthesis that best suits the patient’s physiological features. MedalOne offers three different prosthesis options: the CS type (anterior/posterior cruciate ligament substituting), the CR type (posterior cruciate ligament retaining) and the PS type (posterior-stabilized), covering the mainstream prosthesis types currently available on the market.

The three types of prosthesis feature a high conformity ball-in-socket articulation design in the medial condylar and a high range of motion in the lateral condylar, allowing the knee to move in an arc of 15 degrees in an anterior-posterior direction on the medial axis. These features enable better postoperative satisfaction among patients, who almost “forget” about their knee joint replacement.
