Acute rupture of the knee extensor mechanism after patellectomy is extremely rare. We present the case of a patient with acute patellar tendon rupture who had undergone patellectomy 53 years before. Twelve days after the injury, the ruptured patellar tendon was repaired with end-to-end suture. Postoperatively, we splinted the knee for 6 weeks but permitted the patient to walk without limiting weight bearing at 1 week postoperatively. At one-year follow-up, the patient is able to move his knee almost full range of motion and the Lysholm knee score is 81. The patient is satisfied with the outcome. This is the first report to treat acute rupture of the patellar tendon in a patient who had undergone patellectomy. Although careful rehabilitation is required, end-to-end suture might be an adequate surgical procedure for acute rupture of the knee extensor mechanism after patellectomy.
髌骨切除术后膝关节伸肌机制急性断裂极为罕见。我们报告一例急性髌腱断裂患者的病例，该患者53年前曾接受过髌骨切除术。受伤12天后，采用端端缝合修复断裂的髌腱。术后，我们将膝关节固定6周，但允许患者在术后1周行走且不限制负重。在一年的随访中，患者膝关节活动范围几乎正常，Lysholm膝关节评分81分。患者对结果满意。这是首例关于治疗曾接受髌骨切除术患者的急性髌腱断裂的报告。尽管需要仔细的康复治疗，但端端缝合可能是治疗髌骨切除术后膝关节伸肌机制急性断裂的一种合适的手术方法。
