The effect of platelet-rich plasma (PRP) treatment on recovery in acute hamstring injuries is controversial. Previous study results are inconsistent, and a standardized therapeutic approach has not been established yet.
To assess the treatment effect using a combination of hematoma aspiration and muscle strain PRP injection in partial hamstring muscle tears (grade 2 strains) in athletes.
Magnetic resonance imaging of athletes with grade 2 hamstring strains were reviewed from 2013 to 2018. From 2013 to 2015, athletes were treated conservatively, and from 2016 to 2018, with a combination of ultrasound-guided hematoma aspiration and PRP muscle strain injection. The outcome, including return-to-play (in days) and recurrence rate, was compared retrospectively between both groups (conservative vs aspiration/PRP) using ANOVA and Fisher's exact test. There was no significant difference in age, type of sport, and muscle involvement (including injury grade/location, hamstring muscle type, and length/cross-sectional area of the strain).
Fifty-five athletes (28 treated conservatively, 27 with hematoma aspiration/PRP injection) were included. Average return-to-play time (mean) was 32.4 d in the conservative group and 23.5 d in the aspiration/PRP group (P < 0.001). Recurrence rate of the hamstring strain was 28.6% (8/28) in the conservative treatment group and less than 4% (1/27) in the aspiration/PRP group (P = 0.025).
Athletes with grade 2 hamstring strains treated with a combination of hematoma aspiration and PRP injection had a significantly shorter return-to-play and a lower recurrence rate compared with athletes receiving conservative treatment.
富血小板血浆（PRP）治疗对急性腘绳肌损伤的恢复效果存在争议。先前的研究结果不一致，尚未建立标准化的治疗方法。
评估在运动员部分腘绳肌撕裂（2 级拉伤）中联合使用血肿抽吸和肌肉拉伤 PRP 注射的治疗效果。
对 2013 年至 2018 年患有 2 级腘绳肌拉伤的运动员进行磁共振成像检查。2013 年至 2015 年，运动员采用保守治疗，2016 年至 2018 年，采用超声引导下血肿抽吸和 PRP 肌肉拉伤注射联合治疗。使用方差分析和 Fisher 确切检验，回顾性比较两组（保守治疗组与抽吸/PRP 治疗组）的结局，包括重返赛场时间（以天计）和复发率。两组间在年龄、运动类型和肌肉受累情况（包括损伤分级/部位、腘绳肌类型、拉伤长度/横截面积）方面无显著差异。
共纳入 55 名运动员（28 名接受保守治疗，27 名接受血肿抽吸/PRP 注射）。保守治疗组的平均重返赛场时间（均值）为 32.4 天，抽吸/PRP 治疗组为 23.5 天（P＜0.001）。保守治疗组的腘绳肌拉伤复发率为 28.6%（8/28），抽吸/PRP 治疗组低于 4%（1/27）（P=0.025）。
与接受保守治疗的运动员相比，联合使用血肿抽吸和 PRP 注射治疗 2 级腘绳肌拉伤的运动员重返赛场时间明显缩短，复发率较低。
