Abstract
BACKGROUND: The experience of chronic postsurgical pain (CPSP) can vary widely among patients after rotator cuff repair (RCR). PURPOSE: To determine the prevalence and predictive factors of CPSP at 6 months after RCR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The following assessments were conducted preoperatively and 6 months postoperatively in adult patients with RCR who had undergone primary arthroscopic RCR (N = 1987): Constant score, pain assessed on the numeric rating scale (0-10), the Subjective Shoulder Value, the Oxford Shoulder Score, and quality of life as measured by the EuroQol-5 Dimensions-5 Level (EQ-5D-5L). Patient characteristics-including age, sex, body mass index, and smoking status-and surgical factors-including the duration of surgery and the American Society of Anesthesiologists (ASA) classification-were also reported. Multivariate logistic regression analysis was performed to determine which variables were predictors for CPSP. RESULTS: The prevalence of moderate to severe preoperative pain in the patients was 30.4% for CPSP. After adjusting for age, surgery duration, ASA classification, sex, and body mass index, results revealed that unique predictors for CPSP were as follows: (1) the presence of preoperative negative affect-assessed using the anxiety/depression dimension of the EQ-5D-5L (odds ratio [OR], 1.46 (P < .001); (2) preoperative pain (OR, 1.17; P < .001); and (3) shoulder function (OR, 0.96; P < .001). None of the surgical factors appeared to predict CPSP. CONCLUSION: Patients predisposed to CPSP can be identified during the preoperative phase. Collectively, there is a call for a more in-depth assessment of biopsychosocial risk factors that could substantially influence the postoperative pain experience.
