Functional impact and quality of life after total hip arthroplasty for hip osteoarthritis. A retrospective study of 200 cases.

Résumé

Background: Total hip arthroplasty (THA) is now a well-established and reliable procedure that effectively reduces pain, restores mobility and enhances functionality. This study aim to evaluate the quality of life and functional outcomes of patients who underwent THA for hip osteoarthritis, and to identify the factors influencing these outcomes. Methods: A retrospective study was conducted involving 200 patients who underwent THA for hip osteoarthritis. Functional outcomes were assessed using the Postel-Merle d'Aubigné (PMA) score. Quality of life and patient satisfaction were evaluated using the Short Form Health Survey-12 (SF-12), the Hip Disability and Osteoarthritis Outcome Score (HOOS), the Pittsburgh Sleep Quality Index (PSQI), and the Hospital Anxiety and Depression Scale (HADS). Results: The PMA score increased from 7 to 14 points (p = 0.008), the SF-12 PCS rose from 29.76 to 48.71 (p < 0.001), and the SF-12 MCS increased from 49.24 to 54.49 (p < 0.001). The HOOS improved from 35/100 to 76/100 (p < 0.001). The PSQI decreased from 7/21 to 3/21 (p < 0.001). The HADS depression and anxiety fell from 6.8/21 to 3.8/21 (p < 0.001) and from 8.4/21 to 4.8/21 (p < 0.001), respectively. Physical and mental health were positively associated with walking autonomy and higher BMI. Hip function outcomes were better in patients with ceramic on-ceramic articulations, younger age, and higher postoperative PMA scores. Good sleep quality and decreased depression score were associated with increased walking distance and BMI. There were no significant associations between anxiety and any of the variables investigated. Conclusions: These findings highlight the effectiveness of THA not only in restoring mobility but also in enhancing overall patient well-being. Integrating both functional and quality-of-life assessments into patient care offers a comprehensive approach to postoperative management and may optimize long-term outcomes for patients with hip osteoarthritis.
