title: Evaluation of 100 Müller curved-stem and 276 Müller long-stem total hip arthroplasties after 10 to 15 years of follow-up.
abstract: This study evaluates 376 total hip arthroplasties performed between 1978 and 1983 using 276 Müller long-stem and 100 Müller curved-stem prostheses. Demographic and clinical data were obtained from patient records. All patients still alive who did not undergo revision arthroplasty were sent a detailed questionnaire. Results indicated that long-term survival of the femoral component of the arthroplasty was significantly better when the Müller long-stem was used. Furthermore, there was no difference in the clinical out-come between patients who underwent revision and those who did not. To eliminate demographic differences between the two groups, 77 patients from each group were paired. There was no difference in clinical results of the hips between the paired groups, and long-term survival of the Müller long-stem was still significantly better using Kaplan-Meier analysis.
