Total hip arthroplasty revision using the press-fit CLS Spotorno cementless stem. Twenty-four hips followed between 1987 and 1998.

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.
