中文摘要：

2012年1月至10月,对52例肱骨外上髁炎患者分别行富含血小板血浆（PRP;28例,PRP组）和糖皮质激素局部注射（24例,糖皮质激素组）治疗,对比两者的临床效果.注射治疗后1周时,两组间视觉模拟疼痛评分（VAS）和Mayo医院改良肘关节评分差异有统计学意义；治疗后1个月和6个月时PRP组优于糖皮质激素组（P＜0.05）.PRP痛点局部注射治疗肱骨外上髁炎临床效果良好,优于糖皮质激素治疗.

英文摘要：

A total of 52 patients with chronic lateral epicondylitis were randomly assigned into platelet-rich plasma （PRP） （n =28） or corticosteroid （n =24） group.The visual analog pain scale （VAS） and Mayo elbow score had no significant difference between two groups within 1 week post-treatment.However,VAS and Mayo elbow score improved more significantly in PRP group versus corticosteroid group at Month 1 and 6 post-treatment （P ＜ 0.05）.The PRP trigger point injection treatment of elbow lateral epicondylitis achieved clinical outcomes and it was superior to glucocorticoid treatment.
