富血小板血浆联合关节镜松解治疗冻结肩的疗效分析

目的 评估富血小板血浆（platelet-rich plasma，PRP）联合关节镜松解治疗冻结肩的疗效。方法 回顾性分析2019年1月至2022年12月我科收治的40例采用关节镜松解治疗冻结肩的病人，根据术后注射药物的不同，分为PRP组（20例）和曲安奈德组（20例），记录并比较两组病人术前、术后1个月、术后3个月、术后6个月、术后12个月的疼痛视觉模拟量表（VAS）评分、Constant-Murley肩关节功能评分以及肩关节主动前屈、外展、外旋的活动度。结果 与术前相比，两组病人术后各观察时间点的VAS评分显著降低，Constant-Murley评分显著升高，差异有统计学意义（P＜0.05）。术后6、12个月时，PRP组病人的Constant-Murley评分显著高于曲安奈德组；术后12个月时，PRP组在主动前屈、主动外展、主动外旋活动度方面均要优于曲安奈德组，差异有统计学意义（P＜0.05）。结论 PRP联合关节镜松解能有效缓解冻结肩病人的疼痛，改善肩关节的功能，是一种有效的治疗方案。

Efficacy of Platelet Rich Plasma Combined with Arthroscopic Release in the Treatment of Frozen Shoulder

Objective To evaluate the efficacy of platelet rich plasma (PRP) combined with arthroscopic release in the treatment of frozen shoulder. Methods A retrospective analysis was conducted on 40 frozen shoulder patients treated with arthroscopic release admitted to our Department from January 2019 to December 2022. According to the differences in postoperative medication injection, the patients were divided into PRP group (20 cases) and triamcinolone acetonide group (20 cases). The visual analogue score (VAS), Constant-Murley shoulder function score, and the range of motion of active forward flexion, abduction, and external rotation of the shoulder were recorded and compared before surgery, and 1, 3, 6 and 12 months after surgery. Results Compared with preoperation, the VAS scores in the two groups at each observation time point after surgery were significantly reduced, and Constant-Murley scores were significantly improved (P＜0.05). At 6th and 12th months after surgery, the Constant-Murley score of patients in the PRP group was significantly higher than that in the triamcinolone acetonide group. The PRP group exhibited a better range of motion in active forward flexion, abduction, and external rotation than the triamcinolone acetonide group at 12th month after surgery, with statistically significant differences (P＜0.05). Conclusion PRP combined with arthroscopic release can effectively alleviate pain in frozen shoulder patients and improve shoulder joint function, making it an effective treatment plan.
