Total hip arthroplasty revision using the press-fit CLS Spotorno cementless stem

A retrospective study of uncemented femoral revision for loosening after total hip arthroplasty was conducted for the period 1987–1998. The study included 24 hips in 22 patients (7 men, 15 women). The revision procedure consisted of the replacement of the loose hip prosthesis using the CLS (Protek) press-fit stem. Patients were followed for a mean duration of 4.5 years. The mean interval between the primary operation and the revision was 10 years (range 2–16 years). Using the Merle D’Aubigné hip score and radiographic findings, a favorable outcome was noted in 20 hips. We suggest that the femoral revision procedure using the uncemented Spotorno stem is a very useful method of correction of loosening after total hip replacement.
