目的 探讨关节镜下肩袖缝线桥缝合术后患者疼痛的相关因素。  方法 收集112例接受关节镜下缝线桥缝合的单侧肩袖损伤患者资料，以电话随访的形式，通过数字评分法（NRS）调查患者术后3个月时疼痛情况；SPSS 23.0统计学软件录入数据并分析，采用单因素分析及多重线性回归分析，评价上述影响因素与术后疼痛的相关性。  结果 单因素分析结果显示，病程、吸烟史、患者术前美国加利福尼亚大学洛杉矶分校(UCLA)评分、Constant评分、NRS、肩袖撕裂大小、是否为全层撕裂和肌腱回缩程度8个因素可能与术后疼痛有关(P<0.05)。而患者的年龄、性别、身体质量指数(BMI)、饮酒史、是否合并糖尿病及高血压则与术后疼痛无关(P>0.05)。多重线性回归分析表明，与术后疼痛相关的因素有4个，其相关程度依次是术前NRS、术前UCLA评分、撕裂大小和吸烟史。  结论 影响关节镜下肩袖缝线桥缝合术术后疼痛的复杂且多样，进行术后疼痛的原因分析，可有效减轻患者术后的疼痛，有助于促进肩着节功能恢复。

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.
