Objectives. Simultaneous bilateral total hip arthroplasty (SimBTHA) allows one to replace both hips under one anaesthetic. SimBTHA has been reported to result in fewer complications, reduced costs, and shorter overall hospital stay and rehabilitation time. The purpose of this study was to characterize a cohort of patients selected for SimBTHA.
Materials and Methods. A total of 55 patients who underwent SimBTHA surgery between 1996 and 2020 at the Hospital of Traumatology and Orthopaedics in Rīga, Latvia were included in the study. Both hips were replaced using the direct anterior approach with the patient lying supine. Data from medical records, such as intraoperative parameters and complications, and clinical results at follow-up visits were analyzed. IBM SPSS 27.0 was used to analyze the data.
Results. Most of the patients who underwent SimBTHA had ASA II (63.2%, n = 12) and also had some comorbidity (60%, n = 33). The surgery was completed in an average of 2 hours and 39 minutes. The average length of hospital stay was 14.7 days. The patients were able to walk independently with crutches at 5.6 days (± 3.5) after surgery. The overall frequency of complications was 7.3% (n = 4); all were detected and corrected in the early postoperative period. The mean Harris Hip Score was 95.76 points, indicating an excellent result.
Conclusions. SimBTHA is a successful procedure in terms of clinical outcomes. Future research would be needed to conduct more comprehensive research comparing SimBTHA with staged bilateral total hip arthroplasty.
