MicroPort® Orthopedics has announced a ‘15A’ rating from the Orthopedic Data Evaluation Panel (ODEP) for its independently-developed Advance® Medial-Pivot Knee System.
Established in the United Kingdom in 2002, ODEP is a global rating agency within the orthopedic industry that provides a standardized, validation rating system based on survivorship and the quality of implants throughout a long-term evaluation. At present, ODEP is one of the most authoritative and credible organizations in the field of orthopedics worldwide.
Glendy Wang, Chief Operating Officer of MicroPort® Orthopedics, commented, “The ODEP ‘15A’ rating is a true testament to the superior quality and long-term stable performance of our orthopedic products. We will continue developing new technologies and innovative products based on clinical needs to provide better orthopedic solutions to patients in China and around the world. ”
ODEP uses a combination of a numeric value and a letter in their ratings, where the number represents the total number of years that the joint product has received clinical follow-up, and the letter represents the strength of the product’s clinical data. ‘15A’ is one of the highest clinical follow-up ratings that ODEP gives knee prosthesis products.
With over 20 years of successful clinical experience, the Medial-Pivot Knee System, independently developed by MicroPort® Orthopedics, allows for greater joint range of motion and more reliable wear resistance, as well as helping to rebuild the normal motion mechanics of the knee joint. In addition to the top ODEP rating, the Medial-Pivot Knee product has been recognized in numerous important clinical studies for its superior performance. For example, the results of its 17-year clinical follow-up, which were published in the academic journal The Knee, showed excellent prosthesis survival rate (98.8%) and patient satisfaction (95%). Another study published in The Journal of Arthroplasty found that patients with Medial-Pivot knee prostheses scored higher on the FJS (Forgotten Joint Scores) than those with traditional post-stabilized knee prostheses, and were more likely to “forget” that they had undergone total knee replacement.
