Understanding the optimal management of distal biceps femoris avulsion injuries is critical for restoring preinjury function, restoring hamstring muscle strength, increasing range of motion, and minimizing risk of complications and recurrence. Due to the rarity of these injuries, prognosis and outcomes within the literature are limited to case reports and small case series.
To assess the effect of surgical repair for acute distal avulsion injuries of the biceps femoris tendon on (1) return to preinjury level of sporting function and (2) time to return to preinjury level of sporting function, patient satisfaction, and complications.
Case series; Level of evidence, 4.
This prospective single-surgeon study included 22 elite athletes (18 men [82%], 4 women [18%]; mean age, 26 years; age range, 17-35 years; mean body mass index, 25.3 ± 4.1 kg/m) undergoing primary suture anchor repair of avulsion injuries of the distal biceps femoris confirmed on preoperative magnetic resonance imaging. Predefined outcomes relating to time for return to sporting activity, patient satisfaction, complications, and injury recurrence were recorded at regular intervals after surgery. Minimum follow-up time was 12 months (range, 12.0-26.0 months) from the date of surgery.
The mean time from injury to surgical intervention was 12 days (range, 2-28 days). All study patients returned to their preinjury level of sporting activity, predominately professional soccer or rugby. Mean time from surgical intervention to return to full sporting activity was 16.7 ± 8.7 weeks. At 1- and 2-year follow-up, all study patients were still participating at their preinjury level of sporting activity. There was no incidence of primary injury recurrence, and no patients required further operation to the biceps origin.
Surgical repair of acute avulsion injuries of the distal biceps femoris facilitated early return to preinjury level of function with low risk of recurrence, low complication rate, and high patient satisfaction in elite athletes. Suture anchor repair of these injuries should be considered a reliable treatment option in athletes with high functional demands to permit an early return to sport with restoration of hamstring strength.
了解股二头肌远端撕脱伤的最佳治疗方法对于恢复伤前功能、恢复腘绳肌力量、增加活动范围以及将并发症和复发风险降至最低至关重要。由于这些损伤较为罕见，文献中的预后和结果仅限于病例报告和小型病例系列。
评估股二头肌肌腱急性远端撕脱伤手术修复对（1）恢复到伤前运动功能水平以及（2）恢复到伤前运动功能水平的时间、患者满意度和并发症的影响。
病例系列；证据等级，4级。
这项前瞻性单医生研究纳入了22名精英运动员（18名男性[82%]，4名女性[18%]；平均年龄26岁；年龄范围17 - 35岁；平均体重指数25.3±4.1kg/m²），他们因术前磁共振成像确诊为股二头肌远端撕脱伤而接受了初次缝线锚钉修复。术后定期记录与恢复运动活动时间、患者满意度、并发症和损伤复发相关的预定义结果。自手术日期起，最短随访时间为12个月（范围12.0 - 26.0个月）。
从受伤到手术干预的平均时间为12天（范围2 - 28天）。所有研究患者均恢复到伤前运动活动水平，主要是职业足球或橄榄球运动。从手术干预到恢复全面运动活动的平均时间为16.7±8.7周。在1年和2年随访时，所有研究患者仍在伤前运动活动水平参与运动。没有原发性损伤复发的情况，也没有患者需要对股二头肌起点进行进一步手术。
股二头肌远端急性撕脱伤的手术修复有助于精英运动员早期恢复到伤前功能水平，复发风险低、并发症发生率低且患者满意度高。对于功能需求高的运动员，这些损伤的缝线锚钉修复应被视为一种可靠的治疗选择，以便早期恢复运动并恢复腘绳肌力量。
