Verification of the Australian Orthopaedic Association National Joint Replacement Registry using a surgeon's database.

PURPOSE To assess the completeness of registration and any discrepancies between the senior author's database and the Australian Orthopaedic Association National Joint Replacement Registry (AOA NJRR). METHODS From 2002 to 2005, the senior author performed 231 primary total hip arthroplasty (THA) on 217 patients using the Corail femoral stem and one of the 3 types of the acetabular component: Pinnacle, ASR, or Duraloc/Option. The name of each patient was forwarded to the AOA NJRR for matching and verification. RESULTS The AOA NJRR recorded 230 of the 231 primary THAs; all but one was matched with the senior author's database. Nine (3.9%) of them were revised by the same (n=7) or another (n=2) surgeon. Three (43%) of the 7 revision surgeries were not recorded on the AOA NJRR. One patient revised for a ceramic liner fracture was incorrectly recorded as 'wear acetabulum' in the AOA NJRR. CONCLUSION Although the AOA NJRR achieved high registration completeness for primary THA, accuracy for revision THA was much lower.
