Objective To analyze the factors associated with pain after arthroscopic rotator cuff bridge suture.   Methods According to the inclusion and exclusion criteria, the data of 112 patients with unilateral rotator cuff injury who received arthroscopic bridge suture in our department were collected and were investigated in the form of telephone follow-up. In this study, SPSS 23.0 was used to input data and conduct statistical analysis. Logistic regression analysis was used to analyze the correlation between the above influencing factors and postoperative pain.   Results A total of 112 patients were included for statistical analysis, single factor analysis revealed, including course of disease, smoking history, preoperative University of California, Los Angeles (UCLA) score, Constant score, numeric rating scale (NRS), size of rotator cuff tear, whether it was full-thickness tear and degree of tendon retraction might be related to postoperative pain (P<0.05). The age, gender, body mass index (BMI), drinking history, diabetes and hypertension were not related to postoperative pain (P>0.05). Multiple linear regression analysis concluded that there were four factors related to postoperative pain, and the correlation degree was preoperative NRS, preoperative UCLA score, tear size and smoking history.   Conclusion The causes of postoperative pain after arthroscopic rotator cauff repair are complex and diverse. Analyzing the cause of postoperative pain can effectively reduce the pain of patients and promote the recovery of shoulder joint function.
