Abstract
Thirty-two cemented revision hip arthroplasties done with a straightstem Muller prosthesis were reviewed an average of 3 years after operation (range, 2–4.4 years). Acetabular revision, performed in 29 cases, was done with a support ring, mesh, or bone graft in 18 of 29 (62%) cases. Acetabular and femoral cement pressurization techniques were not used. Trochanteric osteotomy was done in 15 cases (47%). The average patient age was 60.2 years (range, 20–85 years). Based on the clinical rating system of Swanson and Evarts, there were 21 (65.6%) excellent, 2 (6.3%) good, 8 (25%) fair, and 1 (3.1%) poor results. The clinical outcome was better after revision from a resurfacing arthroplasty (87.5% good/excellent results) than from uni/bipolar or total hip arthroplasty (60%). Radiographic examination suggests that two femoral components and one acetabular component are loose. These patients have a fair clinical rating. None have been revised. Trochanteric wire breakage (60%) and displacement (26.7%) was common if trochanteric osteotomy was done
