Migration of the femoral interference screw in to the knee joint following anterior cruciate reconstruction is a rare complication. A migrated interference screw usually requires removal as it often results in mechanical symptoms. Formal arthrotomy may be required to remove a dislodged screw lying in the femoral notch because arthroscopic removal can be difficult or not possible in the presence of an intact integrated anterior cruciate ligament graft or scarring in the notch. When attempting arthroscopic removal in a similar situation, one should foresee the possibility of a formal arthrotomy and this should be discussed with the patient and consent obtained preoperatively.
前交叉韧带重建术后股骨挤压螺钉移入膝关节是一种罕见的并发症。移位的挤压螺钉通常需要取出，因为它常常会导致机械性症状。对于位于股骨切迹内的移位螺钉，可能需要进行正式的关节切开术，因为在存在完整的前交叉韧带移植物或切迹内有瘢痕形成的情况下，关节镜下取出可能困难或无法进行。在类似情况下尝试关节镜下取出时，应预见到可能需要进行正式的关节切开术，并应与患者讨论此事并在术前获得同意。
