Efficacy of bed exercise in elderly patients after total hip arthroplasty: A retrospective study of 539 patients

Abstract

The purpose of this study was to observe the necessity of bed exercise therapy in the rehabilitation of elderly patients after hip replacement and to analyze whether bed exercise therapy has an impact on patients' psychological scores, hip function and postoperative complications. From January 2018 to January 2021, a total of 539 patients with end-stage femoral head necrosis or hip osteoarthritis were retrospectively analyzed. According to the method of postoperative rehabilitation exercise, patients were divided into 2 groups: Group A (routine gait) and Group B (bed exercise). There was no significant difference in general information between the 2 groups. There was no significant difference in baseline pain scores between patients in Group A and Group B (25.2±9.6 vs 24.8±10.4, P=.429). However, at 5 weeks post-operatively, the pain scores of patients in Group A were significantly higher than those in Group B (38.6±7.7 vs 34.1±8.1, P=.016). At 17 weeks post-operatively, the difference between Group A and Group B remained (40.9±6.9 vs 37.5±7.5, P=.041). Similar to the pain score, the hip function score compared between the 2 groups was significantly different at 5 weeks (39.7±8.4 in Group A, 45.9±9.2 in Group B, P
