Abstract：
METHODS: A 29-year-old man sustained a bilateral acute patellar tendon rupture (PTR) while jumping on a trampoline. He was initially treated with bilateral transosseous patellar tendon repairs. Bilateral rerupture occurred during a fall 10 weeks after. He subsequently underwent staged bilateral patellar tendon reconstructions using an Achilles tendon allograft. At 3-year follow-up, he has maintained full range of motion and leg strength without rerupture or other complications.
CONCLUSIONS: The use of Achilles tendon allograft in the presence of inadequate and poor-quality tendon tissue for reconstruction of the patellar tendon in the revision setting is a viable and effective treatment option.

摘要：
方法：一名29岁男子在蹦床上跳跃时出现双侧急性髌腱断裂（PTR）。他最初接受了双侧穿骨髌腱修复术。双侧再破裂发生在跌倒10周后。随后，他使用跟腱同种异体移植进行了分阶段的双侧髌腱重建。在3年的随访中，他保持了全方位的运动和腿部力量，没有再破裂或其他并发症。
结论：在肌腱组织不足和质量差的情况下，使用跟腱同种异体移植重建髌腱是一种可行和有效的治疗选择。
