BACKGROUND
We report a case of hardware failure after distal femoral osteotomy (DFO) with a broken screw pulled out from the locking hole and positioned within the knee joint.
CASE PRESENTATION
A 57-year-old man presented to our orthopedic outpatient department with 3-months history of an unusual painful swelling at the operated area following DFO. The leakage of joint fluid from the penetrated suprapatellar pouch was assumed to be the reason for this complication.
CONCLUSIONS
The overall aim of this case report is to provide a lesson to budding surgeons who might experience a similar situation that cannot be easily explained, like the unexpected complication in the present case.
背景
我们报告一例股骨远端截骨术（DFO）后硬件故障的病例，一枚断裂螺钉从锁定孔中拔出并位于膝关节内。
病例介绍
一名57岁男性因DFO术后手术区域出现异常疼痛肿胀3个月，前来我们的骨科门诊就诊。关节液从髌上囊穿透处渗漏被认为是该并发症的原因。
结论
本病例报告的总体目的是给初出茅庐的外科医生提供一个教训，他们可能会遇到类似难以解释的情况，就像本病例中的意外并发症一样。
