Optimization of physical functioning of patients before and after total hip arthroplasty

Background and Purpose Self-report and performance-based measures of physical functioning in people before and after total hip arthroplasty seem to present different information. The relationship between these different measures is not well understood, and little information is available about changes in this relationship over time. The aims of this study were: (1) to determine the relationship between self-report and performance-based measures of physical functioning before and after total hip arthroplasty, (2) to assess the influence of pain on the relationship, and (3) to determine whether the relationship changes over time. Subjects and Methods Seventy-five subjects admitted for total hip arthroplasty were included and examined before and 6 and 26 weeks after surgery. The relationships between the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) physical functioning subscale and walking speed and gait variability were examined by use of generalized estimating equations, which included interactions with time and the WOMAC pain subscale. Results The relationship between self-report and performance-based measures of physical functioning was poor. Pain appeared to have a considerable influence on self-reported physical functioning. The relationship did not appear to change over time. Discussion and Conclusion The influence of pain on self-reported physical functioning serves as an explanation for the poor relationship between self-reported and performance-based physical functioning. When using a self-report measure such as the WOMAC, one should realize that it does not seem to assess the separate constructs—physical functioning and pain—that are claimed to be measured.

Introduction: Sexual activity is often an important component of life. To date, no studies have examined sexual activity before and after total hip arthroplasty (THA) in male patients with ankylosing spondylitis (AS). The purpose of the current study was to evaluate the effect of THA on sexual activity and to explore the most commonly reported and comfortable coital position for male AS patients with hip involvement. Methods: Data from 31 male AS patients who underwent THA for hip involvement were retrospectively reviewed. Information from the International Index of Erectile Function (IIEF), the Harris Hip Score (HHS) and other clinical parameters was collected and monitored over time. We compared the above-mentioned parameters before surgery and 2 years after surgery and analysed the correlation between changes on the IIEF and changes in clinical parameters. Results: The domain and total scores of the IIEF, except EF, were significantly higher after surgery than were those before surgery ( p < 0.05). There was a significant positive correlation between changes on the IIEF and improvement in flexion-extension range of motion (ROM), adduction-abduction ROM and HHS ( p < 0.05). Most patients (26/31, 83.9%) resumed sexual activity 5–12 weeks after surgery. The pre- and postoperative distributions of the most commonly reported and comfortable position were not significantly different (p > 0.05). Conclusions: Successful THA may improve sexual activity in male AS patients with hip involvement. Changes in hip ROM show the most significant correlation with improvement in sexual activity. Resumption of sexual activity occurs within 5–12 postoperative weeks.

Introduction: The correct moment for return to driving after total hip arthroplasty (THA) remains unclear. Until today no uniform recommendation exists on the ability to perform an emergency brake. The aim of this prospective study was to investigate the braking ability of patients before and after THA implantation based on brake reaction time in milliseconds (BRT) and braking force in N (BF). Methods: In total, 25 patients (15 men, 10 women, mean age 51.3 ± 10.1 years) were treated with THA on the right side. Inclusion criteria consisted of a valid driving licence, frequent road participation and at least 2 years of driving experience. Exclusion criteria were underlying neurological disorders as well as severe complaints in the lumbar spine and the right knee joint. The brake ability was evaluated for emergency braking with a car simulator and a measuring sole. Measurements were performed preoperatively, 6 days, 2, 4 and 6 weeks after surgery. Results: Preoperatively, the mean BRT was 671.3 ± 123.5 ms and the BF 455.4 ± 185.0 N. Significant differences were observed at 6 days and 2 weeks after surgery, (BRT 836.4 ± 219.7 ms, respectively, BRT 735.0 ± 186.7 ms, and BF 302.6 ± 154.9 N, respectively, BF 375.5 ± 149.3 N, p < 0.05). Only 4 weeks after, no significant differences were seen compared to pre-operative with a BRT of 647.0 ± 91.9ms ( p = 0.354) and BF of 435.9 ± 177.4 ( p = 0.843). Furthermore, the BRT improved significantly after 6 weeks (607.4 ± 87.6; p = 0.005). Conclusions: The braking force is significantly reduced, and the brake reaction time is prolonged directly after surgery for at least 2 weeks. After 4 weeks, no statistically significant differences were measured, although special care should still be taken during return to activity.
