Objective:To study effect of shoulder joint function after rotator cuff repair of polylactic acid absorbable membrane.Methods:From September 2015 to December 2016,50 patients diagnosed with rotator cuff tear were selected and divided into treatment group and control group.There were 25 patients in control group,including 12 males and 13 females,with an average age of (48.7±3.5) years old,who received simple arthroscopic rotator cuff repair.There were 25 patients in treatment group,including 11 males and 14 females,with an average age of (49.2±4.1) years old,who performed arthroscopic rotator cuff repair with implanting polylactic acid absorbable membraneon shoulder of rotator cuff.Preoperative and postoperative VAS score,ASES score and UCLA score were recorded and compared between two groups.Results:At 6 months after operation,preoperative VAS score in control group was 5.48±1.12,and decreased as 1.28±0.84 after operation;ASES score before operation was 52.24±4.64,and improved to 86.92±3.20 after operation;preoperative UCLA score improved from 14.36± 1.89 before operation to 30.72±1.28 after operation.In treatment group,VAS score decreased from 5.36±1.32 before operation to 1.40±0.71 after operation;preoperative ASES score was 51.04±4.09,and improved to 88.96±2.79 after operation;UCLA score improved from 15.12±1.81 before operation to 32.12±1.33 after operation.There was no significant difference in VAS score between two groups,and ASES score,UCLA score in treatment group was obviously better than control group.Conclusion:Application of polylactic acid absorbable medical membrane could obviously improve shoulder function,and effectively prevent acromion adhesion after arthroscopic rotator cuff repair.%目的:探讨高分子聚乳酸可吸收医用膜对肩袖修补术后肩关节功能的影响.方法:选取2015年9月至2016年12月确诊肩袖破裂的患者50例:对照组25例,男12例,女13例,平均年龄(48.7±3.5)岁,单纯行关节镜下肩袖修补术;试验组25例,男11例,女14例,平均年龄(49.2±4.1)岁,行关节镜下肩袖修补术加肩峰下间隙肩袖表面植入高分子聚乳酸可吸收医用膜.记录并分析每组患者手术前后肩关节VAS、ASES、UCLA评分.结果:术后6个月随访时,对照组VAS评分从术前的5.48±1.12降低至术后的1.28±0.84,ASES评分由术前的52.24±4.64提高至术后的86.92±3.20,UCLA评分由术前的14.36±1.89提高至术后的30.72±1.28;试验组VAS评分由术前的5.36±1.32降低至术后的1.40±0.71,ASES评分由术前的51.04±4.09提高至术后的88.96±2.79,UCLA评分由术前的15.12±1.81提高至术后的32.12±1.33.两组VAS评分差异无统计学意义,ASES、UCLA评分试验组优于对照组.结论:高分子聚乳酸可吸收医用膜的应用较常规关节镜下肩袖修补术可明显提高术后肩关节功能,可有效预防关节镜下肩袖修补术后肩峰下粘连.
