Penn State Hershey Bone and Joint Institute Participates in the American Joint Replacement Registry

hipreplacement-300wMore than 1.4 million total hip and knee replacements were performed in the United States in 2012, according to statistics from the Centers for Disease Control  [website] . Charles Davis, M.D., Penn State Hershey Bone and Joint Institute notes, “This presents a valuable opportunity to identify surgical procedures and implant devices that work best, as well as to better understand patient outcomes.”

Recently, Davis and his colleagues became contributing participants in the American Joint Replacement Registry (AJRR). The AJRR is a nonprofit collaborative effort supported by the American Academy of Orthopaedic Surgeons (AAOS), the American Association of Hip and Knee Surgeons (AAHKS), the Hip Society, the Knee Society, hospitals, health insurers, and medical device manufacturers. Davis says, “Our own internal registry database has been in place for several years, as a tool to track patient progress and provide feedback about what techniques were the most successful. It was a natural step to begin participation in the AJRR. One of the main benefits is that now we’ll receive annual reports not only for our own patient outcomes but outcomes seen on the national level to which we otherwise wouldn’t have access.”

With the AJRR, the large number of cases gives researchers the ability to see patterns of risk and benefit that cannot be discerned in smaller case series. “One of the primary objectives of the registry is to identify prosthesis failures, like those seen with metal-on-metal hip replacement procedures. It’s also important to evaluate benefits like patient functional recovery. Over time, the AJRR will demonstrate increasing value, as more centers begin participating, and as patients are added and followed for longer periods of time,” explains Davis.
