Core Tip
Core Tip: This study reveals that preoperative factors, particularly central sensitization (Central Sensitization Index), psychological status (Center for Epidemiologic Studies Depression Scale), and functional impairment (Western Ontario and McMaster Universities Osteoarthritis Index), significantly influence recovery outcomes after total hip arthroplasty. Unlike intraoperative factors, these patient-specific characteristics strongly predicted clinical scores at six months postoperatively. Notably, age, Western Ontario and McMaster Universities Osteoarthritis Index, and Central Sensitization Index were consistent predictors across outcomes, emphasizing the importance of comprehensive preoperative evaluations. These findings underscore the critical role of addressing central sensitization and psychological health in optimizing recovery after total hip arthroplasty, offering valuable insights for personalized patient management and improved functional outcomes in advanced hip disorder interventions.
