Acute locking of the joint in a replaced knee joint is very rare. This report describes an acute locking episode of a revised modular total knee replacement, occurring more than 2 years after surgery. A disengaged screw from the modular femoral component had lodged in the joint at the inferior pole of the patella and required urgent arthroscopic removal. There was no subsequent failure of the stem-condylar junction, nor loosening of the femoral component.
人工膝关节置换术后关节急性锁定非常罕见。本报告描述了一例翻修型模块化全膝关节置换术后超过2年发生的急性锁定事件。一枚从模块化股骨部件脱离的螺钉嵌入髌骨下极的关节内，需要紧急关节镜下取出。随后，柄-髁关节交界处未出现故障，股骨部件也未松动。
