ABSTRACT
BACKGROUND:
Registry data for total hip arthroplasty (THA) has allowed optimal fixation methods, bearing surfaces and many other factors to be assessed. We describe 10-year THA outcomes from an Irish perspective using regional THA registry data for the first time.AIMS:
We assess the main predictors of revision in primary total hip arthroplasty (THA) using regional registry data.METHODS:
This was a prospective study of registry data from a National Orthopaedic Hospital for all THAs with 10-year follow-up data. All metal-on-metal THAs and resurfacings were excluded from the analysis. All-cause revision was the primary outcome. Univariate and multivariate analyses controlling for confounding variables were performed to assess predictor impact on primary and secondary outcomes.RESULTS:
A total of 1697 THAs were performed in 1553 patients. The three significant predictors for all-cause revision were fixation type (p < 0.01), surface bearing type (p < 0.01) and femoral head size (p < 0.05). The lowest 10-year all-cause revision rates were seen in cemented THRs at 1.2%. Ceramic-on-poly bearings had the lowest revision rate at 0.9%. The 22.225-mm head sizes had a significantly lower revision rate than other head sizes (p < 0.05). The causes for revision in order of decreasing frequency were infection (0.7%), dislocation (0.4%), periprosthetic fracture (0.2%) and aseptic loosening (0.1%). There were two re-revisions at 10 years in total.CONCLUSIONS:
Based on this registry and other emerging registry data, the shift towards uncemented THAs may not be fully supported. We also acknowledge that ceramic-on-polyethylene bearings afford the lowest revision rates in this registry.Palavras-chave
