Few studies have reported on the use of knotless suture anchors to treat patellar tendon rupture from tibial tuberosity after total knee arthroplasty (TKA). We report a case of patellar tendon rupture in an 82-year-old female. She fell 8 weeks after bilateral TKA and presented with a patellar tendon rupture. A knotless suture anchor and a fully threaded Twist-In knotless anchor with flat-braided suture were used to repairing the patellar tendon. Complications related to the extension mechanism after TKA can lead to disastrous consequences. This surgical procedure is a safe and good treatment option to repair patellar tendon rupture after TKA.

很少有研究报道使用无结缝线锚钉治疗全膝关节置换术（TKA）后胫骨结节处的髌腱断裂。我们报告一例82岁女性的髌腱断裂病例。她在双侧TKA术后8周摔倒，出现髌腱断裂。使用无结缝线锚钉和带扁平编织缝线的全螺纹扭入式无结锚钉修复髌腱。TKA后与伸展机制相关的并发症可能导致灾难性后果。这种手术方法是修复TKA后髌腱断裂的一种安全且良好的治疗选择。
