Muscle injuries, such as Achilles and quadriceps tendon ruptures, pose a significant challenge in elite sports, accounting for more than 30% of all sports-related injuries. Our primary goal is to investigate the MR imaging characteristics of tendon rupture in sports injuries and their relationship with patients' clinical symptoms. In our retrospective study at Zhejiang University of Traditional Chinese Medicine's Second Affiliated Hospital (Zhejiang Xinhua Hospital), we compared the clinical presentation and MRI results of 106 patients with isolated AT and QT ruptures. In the AT, the enthesis was identified as a common site of bony avulsions (30.2%). In contrast, insertional ruptures were more common in the gastrocnemius heads (69.8% and 66.0%). The low frequency of mid-substance tears (13.2% to 20.8%) demonstrated the central tendon region's inherent tensile strength. The ruptured musculotendinous junctions affected the soleus (20.8%). In QT, bony avulsions play a minor role (5.1% to 11.3%). The patella was the primary site of tears (42.2% - 45.3%), with the Vastus intermedius favoring proximal tears (58.5%). Our examination of AT and QT ruptures across sub-components sheds light on their distinct patterns and the implications for clinical practice in terms of precise diagnosis, personalized treatment, and, ultimately, better patient outcomes for these debilitating injuries.
肌肉损伤，如跟腱和股四头肌肌腱断裂，在精英运动中构成了重大挑战，占所有运动相关损伤的30%以上。我们的主要目标是研究运动损伤中肌腱断裂的磁共振成像特征及其与患者临床症状的关系。在我们于浙江中医药大学附属第二医院（浙江新华医院）进行的回顾性研究中，我们比较了106例孤立性跟腱和股四头肌肌腱断裂患者的临床表现和磁共振成像结果。在跟腱中，附着点被确定为骨撕脱的常见部位（30.2%）。相比之下，腓肠肌头的插入性断裂更为常见（分别为69.8%和66.0%）。肌腱中部撕裂的发生率较低（13.2%至20.8%），表明肌腱中央区域具有固有的拉伸强度。断裂的肌腱肌肉连接处累及比目鱼肌（20.8%）。在股四头肌肌腱中，骨撕脱起的作用较小（5.1%至11.3%）。髌骨是撕裂的主要部位（42.2% - 45.3%），股中间肌更易发生近端撕裂（58.5%）。我们对跟腱和股四头肌肌腱断裂各亚成分的检查揭示了它们不同的模式，以及在精确诊断、个性化治疗方面对临床实践的意义，最终为这些使人衰弱的损伤带来更好的患者预后。
