Aim: Performing total hip artroplasty is possible even without or in weak hip abductor muscles. In nonfunctioning or malfunctioning hip abductors, the solution is dual mobility total hip arthroplasty or constrained liner. Methods: primary or revision total hip arthroplasty which needed constrained liner during 2005-2014 were included in this study. Harris hip score (pre-operative, post-operative), leg length discrepancy, type of cup (cemented or cementless), type of stem (standard or long) and approach were considered. Results: according to the results, Harris hip score improved significantly (from 54 to 88, average) after surgery. During the study, disengagement of head from the stem was seen in one case. Also, in a patient, hip dislocation observed. One case of component loosening and failure was detected. In a patient, retro-acetabular osteolysis was seen. Additionally, there was one case with deep infection. Conclusion: these results suggest functional hip score improved dramatically using constrained liner in patients with low complication rate.
