A 51-year-old woman, affected by end-stage renal disease, presented with 16-month-old ruptures of the right patellar tendon and the left quadriceps tendon. Since she had been nonambulatory for more than a year, the authors decided to perform a bilateral one-staged reconstruction with an Achilles tendon allograft on the right side and a full extensor mechanism allograft on the left side, achieving excellent clinical and functional results at 57 months' follow-up.
Bilateral spontaneous rupture of the extensor mechanism of the knee is a rare but dramatic occurrence. Allograft can be considered as a treatment option in case of chronic lesion or delayed reconstruction, with satisfactory midterm outcomes.
一名51岁患有终末期肾病的女性，右髌腱和左股四头肌肌腱出现16个月的断裂。由于她已超过一年无法行走，作者决定进行双侧一期重建，右侧采用同种异体跟腱移植，左侧采用同种异体全伸肌机制移植，在57个月的随访中取得了优异的临床和功能结果。
膝关节伸肌机制双侧自发性断裂是一种罕见但严重的情况。对于慢性损伤或延迟重建，同种异体移植可被视为一种治疗选择，中期结果令人满意。
