Background Total hip arthroplasty (THA) provides high functional scores and long-term survivorship. However, differences in function and disability between men and women before and after arthroplasty are not well understood. Questions/purposes We determined if there was a gender difference in patient-perceived functional measures and range of motion in primary THA. Methods We retrospectively studied 532 patients (658 hips) undergoing primary THA. A total of 59% were women and 41% were men. Patients were assessed preoperatively and at minimum 2 years using Quality of Well-being, SF-36, WOMAC, and Harris hip score. We determined if differences existed between genders before and at followup for all dependent measures. Independent t-tests were also used to determine differences between genders concerning the change (D) scores and hip range of motion. The time course of perceived functional recovery was also documented.

Background Many studies show gender and ethnic differences in healthcare utilization and outcomes. Patients' presurgical cognitions regarding surgical outcomes also may vary by gender and ethnicity and play a role in explaining utilization and outcome differences. However, it is unclear whether and to what extent gender and ethnicity play a role in patients' presurgical cognitions.

Background Excessive alcohol consumption has been associated with adverse health measures after elective surgery. The effects of low or moderate consumption remain unclear. Question/purposes We determined differences among patients with different consumption levels in (1) preoperative and postoperative patient-perceived outcomes and hip scores, (2) changes in those scores from preoperatively to postoperatively, (3) demographics and comorbidities, and (4) length of stay (LOS) and hospitalization charges.
