RT Journal A1 Maloney, William J. T1 The Role of Orthopaedic Device Registries in Improving Patient Outcomes JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 2011 FD December 21 VO 93 IS 24 SP 2241 OP 2241 DO 10.2106/JBJS.9323edit UL http://dx.doi.org/10.2106/JBJS.9323edit AB Recent failure of metal-on-metal bearing surfaces utilized in total hip replacement has once again led to renewed interest in joint replacement registries. The current mechanisms that are in place to monitor hip and knee device performance are clearly inadequate and do not serve the interest of patients, surgeons, or device manufacturers. Failure to adequately monitor implant performance and provide feedback to surgeons and hospitals is unfortunately not a new problem. There was widespread discussion of this issue after the Sulzer hip replacement recall (December 2000), leading Kenneth Chang from The New York Times to write “No one keeps complete track of who has what.”1 Unfortunately, not much has changed since that time. As the great philosopher Yogi Berra once said, “It's like déjà vu, all over again.”
