Abstract
- Purpose: The purpose of this study was to evaluate clinical and radiographic results of revision total hip arthroplasty with constrained liner in patients with abductor insufficiency. Materials and Methods: In this study, 30 patients treated with constrained liner during revision total hip arthroplasty due to abductor insufficiency were evaluated after minimum 2-year follow-up. There were 14 men and 16 women and the mean follow-up period was 4.6 years. Re-dislocation and aseptic loosening of the implant were defined as a failure of the constrained liner. Harris hip score and ambulatory function were evaluated as a clinical parameter and osteolysis, aseptic loosening of the implant and other complications were evaluated as a radiologic parameter. Results: During the follow-up period, there were 4 cases (13.3%) of constrained liner failure including two cases of re-dislocation and two cases of acetabular cup aseptic loosening. The average Harris hip score was improved from 38.3 points preoperatively to 73.4 points at last follow up. At the final follow-up, there were 20 cases (66.7%) of improvement in ambulatory function. There was 1 case of infection and 1 case of periprosthetic fracture. Conclusion: Use of a constrained liner during revision total hip arthroplasty showed satisfactory results for prevention of re-dislocation in patients with abductor insufficiency. However longer term studies on loosening of implants are needed.
