On the validity of the results from the Swedish National Total Hip Arthroplasty register.
The Swedish National Total Hip Arthroplasty Register contains more than 200,000 primary and secondary hip replacements. The failure end-point definition is revision. The aim of this thesis was to validate the results presented by the register and to study the outcome of hip replacement surgery in Sweden. ⋯ The clinical and radiographic failure rates were in several tests as high as the revision rates documented in the Swedish THA register. The clinical results were, however, dependent on demographics, the definition of clinical failure and the scoring system used. The results presented by the register with revision as failure end-point give an exact but limited information about the quality of hip replacement surgery in Sweden.
