title: Quality of sexual life after total hip arthroplasty in male patients with osteonecrosis of femoral head.
abstract: BACKGROUND
  Patients with osteonecrosis of the femoral head (ONFH) have a severe impact on their health status, functionality and quality of life. Sexual life is an important component of the quality of life and is still a frequently neglected domain in patients with ONFH. The aims of the study were to evaluate the influence of the disease and the total hip arthroplasty (THA) surgery on quality of sexual life (QSL) in these patients.
  
  
  METHODS
  A prospective, self-controlled study was done. 247 patients of ONFH who underwent unilateral or bilateral THA were asked to complete a standardized QSL questionnaire, and the score of QSL was evaluated preoperatively and at first year follow-up of post-THA operation.
  
  
  RESULTS
  The mean age of the patient was 46.8 (range 25-60) years. 194 cases (78.5%, 276 hips) were alcohol-induced ONFH. There is significant decrease (p = 0.026) in sexual relationship impairment on the 0-8 scale from pre-THA (5.3 ± 0.7) to post-THA (2.3 ± 0.4). There is no significant difference for effect on sexual function (p = 0.14) between pre-THA (2.3 ± 0.4) and post-THA (1.8 ± 0.3). There is significant improvement (p = 0.018) in overall sexual satisfaction degree of patients on the 1-5 scale from pre-THA (2.7 ± 0.2) to post-THA (4.7 ± 0.6), but no significant increase for sexual partner.
  
  
  CONCLUSIONS
  ONFH has impaired relationships with partner and overall sexual satisfaction degree of the male patients; THA has improved significantly relationships with partner and overall sexual satisfaction degree of the male patients, but no effect on sexual function of the patients and overall sexual satisfaction degree of sexual partner.
