Patterns and predictors of weight change before and after total hip arthroplasty in Class 2 and 3 obese patients

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.
