The results of cementless total hip arthroplasty (THA) vary with data from the UK national Joint Registry being less favourable than that from the Australian registry. The senior author started using a fully cementless THA in 2005 and we aimed to gauge the performance of the implants based on their revision data. Between August 2005 and March 2015, 4,802 primary THA (4,309 patients) were performed with a cementless Corail® stem and a cementless Pinnacle® cup. There were 2,086 (43.4%) males and 2,716 (56.6%) females with a median age of 70 years (IQR 13, Range 16–95). There were a number of changes to the surgical technique with respect to the Corail® stem during the ten-year period, which we have categorised as phase 1 and phase 2. We compared the data in the two phases. Data were extracted from a prospectively maintained patient information database.Introduction
