Chronic disruption of the extensor mechanism is a devastating problem after total knee arthroplasty. Quadriceps tendon ruptures occur at an estimated 0.1% prevalence in the setting of total knee arthroplasty. Complete tears of the quadriceps tendon generally have poor results and high rates of rerupture. We present a case of a quadriceps tendon rupture after total knee arthroplasty which reruptured after initial direct repair. The patient presented to us with a chronically retracted rerupture and was subsequently reconstructed successfully with a novel extended medial gastrocnemius-soleus-calcaneus local rotational pedicle flap.
伸肌机制的慢性破坏是全膝关节置换术后一个极具破坏性的问题。在全膝关节置换的情况下,股四头肌肌腱断裂的发生率估计为0.1%。股四头肌肌腱的完全撕裂通常预后较差且再断裂率较高。我们报告一例全膝关节置换术后股四头肌肌腱断裂的病例,该病例在初次直接修复后再次断裂。该患者因慢性回缩性再断裂前来就诊,随后采用一种新型的延长内侧腓肠肌-比目鱼肌-跟骨局部旋转带蒂皮瓣成功进行了重建。
