PURPOSE: Here we report the short-term clinical and radiological results of the Profemur®-R cementless modular revision stem. METHODS: Between June 2002 and May 2006, 68 revision hip arthroplasties were consecutively performed using this stem. Survival at a mean follow-up of 5.2 years was 94%. According to the Paprosky classification, the femoral defect was classified as type 1 in 39 hips (57.3%), type 2 in 18 hips (26.5%), type 3A in ten hips (14.7%) and type 3B in one hip (1.5%). RESULTS: The Harris Hip Score was 49.57 before surgery and averaged 78.28 at the latest follow-up. The Merle d'Aubigne score improved from 9.15 preoperatively to 14.30 postoperatively. Stem stability rated according to the Agora Roentgenographic Assessment (ARA) scoring system averaged 5.22, suggesting a high likelihood of a durable implant. CONCLUSION: The revision prosthesis examined in this study can be considered a viable and useful option in revision hip arthroplasty, even in patients with bony femoral defects.
