Constrained liner use of developing dislocation after total hip arthroplasty: Short-term results

Abstract

Aim: Today total hip arthroplasty is one of the surgical procedures with the most satisfying data. In spite of all these good outcomes, difficult and upsetting complications for patient and surgeon may be encountered after total hip arthroplasty. Constrained liner were developed to reduce the risk for primary total hip arthroplasty patients with cognitive function disorder before surgery and patients with re-dislocation risks. The aim of this retrospective study is to present the clinical outcomes of freedom constrained lıner systems in patients developing dislocation after total hip arthroplasty. Material and Methods: The aim of our study was to present clinical outcomes of fifteen consecutive surgical procedures with freedom anti-luxation revision system (Biomet, Warsaw, IN, USA) from March 2014 to December 2018. Patients were assessed with Harris hip score, Oxford score and Charnley score and early period complications and satisfaction outcomes were evaluated. Results: Only one of the fifteen patients developed complications of intraoperative femur shaft fracture. According to postoperative data of early period outcomes, postoperative Harris hip score and Oxford scores were observed to have significant amelioration. No deep or superficial wound site complications developed. Neurovascular injury complications were not observed in patients. Conclusion: In conclusion, patients with hip arthroplasty procedure with the constrained implant used in our study obtained satisfactory results.
