To evaluate the efficacy of platelet-poor plasma injections for the treatment of acute hamstring muscle strains.
Cohort study.
Outpatient Sports Medicine Clinic.
Twenty consecutive patients with an acute hamstring muscle injury from 2021 to 2022 were included.
Platelet-poor plasma injection into the hamstring muscle strain.
Time (days) until return to full unrestricted participation in sport.
All patients were male collegiate football athletes, with an average age of 20 (±1.6) years old. The most commonly injured muscle was the semitendinosus (65%). After treatment with platelet-poor plasma, patients on average returned to full, unrestricted participation in sport at 29.4 (±7.2) days postinjury, with a statistically significant improvement in pain as early as 2 weeks postinjection. No recurrent injuries to the affected hamstring muscles were seen within 12 months.
PPP may be a safe and effective treatment for acute hamstring muscle strains and may potentially expedite time to return to play.
评估贫血小板血浆注射治疗急性腘绳肌拉伤的疗效。
队列研究。
门诊运动医学诊所。
纳入了2021年至2022年连续20例急性腘绳肌损伤患者。
向腘绳肌拉伤部位注射贫血小板血浆。
恢复完全不受限制的运动参与所需的时间（天）。
所有患者均为大学男子足球运动员，平均年龄20（±1.6）岁。最常受伤的肌肉是半腱肌（65%）。经贫血小板血浆治疗后，患者平均在受伤后29.4（±7.2）天恢复完全不受限制的运动参与，注射后2周疼痛即有统计学意义的显著改善。在12个月内未观察到受影响的腘绳肌再次受伤。
贫血小板血浆可能是治疗急性腘绳肌拉伤的一种安全有效的方法，可能会加快恢复运动的时间。
