Abstract | INTRODUCTION: Total hip arthroplasty using cementless acetabular component had excellent survivorship. It is controversial whether supplemental screw fixation is mandatory and immediate weight-bearing should be allowed. This study aimed at reviewing the clinical and radiological outcomes of patients receiving cementless acetabular component without supplemental screws with a minimum of 10-year follow-up. MATERIALS AND METHODS: This is a prospective study of patients using the same model of cementless acetabular component without supplemental screws from June 1999 to March 2003. Immediate full weight-bearing walking exercise was allowed. The degree of lateral opening angle and migration of the acetabular component were compared in the early postoperative period and in the last follow-up. RESULTS: A total of 70 hips in 58 patients had a minimum of 10-year follow-up (mean ± standard deviation, 13.2 ± 1.3 years). There was no revision of acetabular cup. The mean lateral opening angle was 47.2 ± 7.3 degrees in the early postoperative radiographs (range, 27-70 degrees) and 47.8 ± 7.5 degrees in the final follow-up radiographs (range, 28-71 degrees). The mean change in the lateral abduction angle was 0.6 ± 1.9 degrees (range, -3 to 7 degrees). The vertical distance decreased by a mean of 0.1 ± 1.9 mm (range, -3.0 to 3.0 mm), and the horizontal distance decreased by a mean of 1.3 ± 1.6 mm (range, -3.0 to 3.0 mm). CONCLUSION: Immediate weight-bearing walking did not result in the migration of the cementless acetabular component without screw fixation. |
