Acute hamstring injury that includes intramuscular tendon injury has been suggested to be associated with increased reinjury risk. These observations were based on a relatively small number of retrospectively analysed cases.
To determine whether intramuscular tendon injury is associated with higher reinjury rates in acute hamstring injury.
MRIs of 165 athletes with an acute hamstring injury were obtained within 5 days of injury. Treatment consisted of a standardised criteria-based rehabilitation programme. Standardised MRI parameters and intramuscular tendon injury, the latter subdivided into tendon disruption and waviness, were scored. We prospectively recorded reinjuries, defined as acute onset of posterior thigh pain in the same leg within 12 months after return to play.
Participants were predominantly football players (72%). Sixty-four of 165 (39%) participants had an index injury with intramuscular hamstring tendon disruption, and waviness was present in 37 (22%). In total, there were 32 (19%) reinjuries. There was no significant difference (HR: 1.05, 95% CI 0.52 to 2.12, P=0.898) in reinjury rate between index injuries with intramuscular tendon disruption (n=13, 20%) and without tendon disruption (n=19, 20%). There was no significant difference in reinjury rate (X²(1)=0.031, P=0.861) between index injuries with presence of waviness (n=7, 19%) and without presence of waviness (n=25, 20%).
In athletes with an acute hamstring injury, intramuscular tendon injury was not associated with an increased reinjury rate within 12 months after return to play.
急性腘绳肌损伤，包括肌内肌腱损伤，与再损伤风险增加有关。这些观察结果是基于相对较少的回顾性分析病例得出的。
确定肌内肌腱损伤是否与急性腘绳肌损伤的更高再损伤率相关。
在损伤后 5 天内获得 165 名急性腘绳肌损伤运动员的 MRI。治疗包括基于标准的康复计划。对标准化 MRI 参数和肌内肌腱损伤进行评分，后者分为肌腱撕裂和波浪状。我们前瞻性地记录了再损伤，定义为伤后 12 个月内同一条腿后大腿急性疼痛发作。
参与者主要为足球运动员（72%）。165 名参与者中有 64 名（39%）的指数损伤伴有肌内腘绳肌肌腱撕裂，37 名（22%）有波浪状改变。共有 32 例（19%）再损伤。再损伤率在有肌内肌腱撕裂（n=13，20%）和无肌腱撕裂的指数损伤之间（n=19，20%）没有显著差异（HR：1.05，95%CI 0.52 至 2.12，P=0.898）。有（n=7，19%）和无（n=25，20%）肌内肌腱波浪状改变的指数损伤之间的再损伤率无显著差异（X²(1)=0.031，P=0.861）。
在急性腘绳肌损伤的运动员中，肌内肌腱损伤与伤后 12 个月内的再损伤率增加无关。
