This study aims to assess the effectiveness of psychosocial techniques to decrease postoperative pain and improve perioperative clinical care in orthopedic surgery. A systematic review and meta-analysis was performed to evaluate the effects of psychosocial methods among adults undergoing orthopedic surgeries. The systematic review included both randomized and nonrandomized trials, but only randomized controlled clinical trials (RCTs) were included in the meta-analysis. ⋯ The results indicate that psychosocial interventions, especially patient education and relaxation training, may reduce perioperative side effects and improve recovery in patients undergoing orthopedic procedures, but the quality of evidence is generally low. More well-powered, high-quality studies are needed to increase confidence. PERSPECTIVE: In this meta-analysis of RCTs in orthopedic surgeries, significant benefits in postoperative pain, perioperative anxiety, and recovery were found, suggesting that psychosocial interventions, especially patient education and relaxation techniques, are useful in improving clinical care.
