Abstract

Ninety-five hips with cementless wedge-shaped tapered CLS stem were evaluated with a mean duration of 12.7. years (range, 10.7-17.3. years). All patients were young and diagnosed with osteonecrosis of the femoral head. The Harris hip score was 92 at the latest follow-up. A subsidence greater than 3. mm was found in 3 hips (3.2%). Focal femoral osteolysis was found in 12 hips (12.6%). Endosteal bone formation and bony pedestal were observed in 94 hips (98.9%) and in 26 hips (27.4%), respectively. With revision for stem loosening as the end point, the survivorship showed 98.9% (95% CI, range 96.9%-100%) at 13. years. Stem alignment and proximal femur morphology did not influence loosening of the stem (p> 0.05).
