title: Anxiety and depression and their influence on the quality of life after total hip replacement: preliminary report.
abstract: Objective. The study investigated health-related quality of life in relation to mental status (anxiety and depression) and demographic factors in patients before and after total hip replacement due to osteoarthrosis. Methods. The SF-36, HADS, socio-demographic data questionnaire was delivered to a group of 184 subjects (108 females, 76 males) at the mean age at the time of surgery of 59 years. Questionnaires were delivered to the subjects 2 weeks before the surgery and 6 months after the operation (by mail). Results. Patients after hip replacement showed significant improvement in health-related quality of life in most domains of SF-36 score and summary scale of PCS (Physical Component Summary Scale) and MCS (Mental Component Summary Scale). They also showed improvement in mental status. Elderly patients were more likely to show worse score in MCS and PCS before and after surgery. BMI (body mass index) was correlated only with preoperative PCS. Mental status was associated with postoperative PCS and MCS. Patients who were satisfied with the results of the surgery showed higher PCS and MCS score. Conclusion. Hip replacement surgery brings significant improvement to the quality of life. Age and mental status of those patients influence markedly their postoperative performance.
