The intra-articular migration of a femoral interference screw is a rare complication after anterior cruciate ligament (ACL) reconstruction in the knee. Only a few reports of cases have been published within the last few years and different approaches toward this complication have been described. We report the case of a 23-year-old female patient who was admitted with knee pain after undergoing an ACL reconstruction 4 years previously. After the clinical examination, a knee radiograph in 2 planes revealed a dislocated femoral interference screw lying in the popliteal fossa. During arthroscopy, the interference screw was retrieved through an additional posteromedial portal to avoid an arthrotomy. The causes for intra-articular screw migration are multiple and most cases were reported in the early postoperative period. The arthroscopic removal of a screw is recommended because of the lower morbidity.
股骨挤压螺钉在关节内移位是膝关节前交叉韧带（ACL）重建术后一种罕见的并发症。在过去几年中仅有少数病例报告发表，且针对该并发症描述了不同的处理方法。我们报告一例23岁女性患者，她在4年前接受ACL重建术后因膝关节疼痛入院。临床检查后，双平面膝关节X线片显示一枚移位的股骨挤压螺钉位于腘窝。关节镜检查时，通过额外的后内侧入路取出挤压螺钉以避免切开关节。关节内螺钉移位的原因是多方面的，大多数病例报告发生在术后早期。由于较低的发病率，建议采用关节镜下取出螺钉。
