关节镜下术中应用富含血小板血浆治疗顽固性肩袖钙化性肌腱炎的临床效果

摘要

Objective To explore the clinical efficacy of platelet-rich plasma(PRP) during arthroscopic debridement for refractory calcific rotator cuff tendonitis .Methods Forty-two patients with refractory calcific rotator cuff tendonitis were divided into PRP group and control group using the random number table ,with 21 cases in each group .Arthroscopic debridement for calcification was conducted in both groups.Intraoperative injections of PRP and normal saline into rotator cuff defect were performed in the PRP group and control group respectively.The University of California at Los Angeles (UCLA) shoulder score and American Shoulder and Elbow Surgeons (ASES) score were compared between the two groups before operation ,and at 1,3,6 and 12 months after operation .The postoperative recovery of rotator cuff injury was also compared between the two groups .Results No significant differences were found in the UCLA or ASES scores between the two groups(P>0.05),but the scores of both groups increased with the increasing observation time (P<0.05).There was no significant difference in the recovery rate of rotator cuff injury between the two groups at 12 months after operation(P>0.05).Conclusion Application of PRP during arthroscopic debridement for refractory calcific rotator cuff tendonitis has no obvious effects on promoting the recovery of rotator cuff injury .%目的 探讨关节镜下清除术中应用富含血小板血浆(PRP)治疗顽固性肩袖钙化性肌腱炎的临床效果.方法 将42例顽固性肩袖钙化性肌腱炎患者按随机数字表法分为PRP组和对照组各21例,两组均行关节镜下钙化灶清除术,PRP组术中于肩袖缺损处注入PRP,对照组术中于肩袖缺损处注入等量生理盐水.比较两组患者术前及术后1、3、6、12个月的加州大学(UCLA)肩关节评分系统、美国肩与肘协会评分系统(ASES)评分以及术后肩袖愈合情况.结果 两组UCLA、ASES评分比较差异均无统计学意义(P>0.05),但均随观察时间的延长而增高(P<0.05).两组术后12个月肩袖损伤愈合率的比较,差异无统计学意义(P>0.05).结论 关节镜下钙化灶清除术中应用PRP治疗顽固性肩袖钙化性肌腱炎在促进肩袖损伤愈合方面无明显效果.
