We present a case of a 41-year-old male bodybuilder with a partial delaminated quadriceps tendon rupture after a traumatic injury. Partial quadriceps tendon tears are rare overall and usually are treated nonoperatively with conservative management depending on the patient's limitations. He was found to have an intact superficial quadriceps tendon with a partial thickness tear of the vastus intermedius and delamination of the undersurface quadriceps tendon precluding active knee extension.
To our knowledge, there has never been a reported partial quadriceps tendon tear with delamination of the undersurface, causing a complete extensor mechanism failure necessitating operative repair.
我们报告了一例 41 岁男性健美运动员，因外伤导致部分股四头肌腱撕裂分离。总的来说，部分股四头肌腱撕裂较为罕见，通常根据患者的限制情况，采用非手术保守治疗。该患者发现其浅层股四头肌腱完整，股中间肌部分厚度撕裂，股四头肌腱底面分层，导致主动伸膝功能丧失。
据我们所知，从未有过报道称部分股四头肌腱撕裂分离导致整个伸肌机制失效，需要手术修复。
