This report is being filed after the review of the following journal article: lee, b., et al (2010), delayed foreign body reaction due to bioabsorbable pins used for femoral fixation in anterior cruciate ligament reconstruction: a case report, the american journal of sports medicine, vol.38 (1), pages 176-180 (korea, south).This study emphasizes on: to report a delayed, extensive foreign body reaction to the rigidfix pin with osteolytic femoral tunnel widening and huge extraarticular fluid collection 1 year and 10 months after the acl reconstruction.The patients evaluated on course of this study: a case report of a (b)(6) man, a soccer player, who suffered a noncontact twisting injury to his right knee 3 weeks before presentation at the clinic.At the time, he felt a pop and was unable to continue with the game.His knee became swollen a few hours after the injury.At the presentation, the findings of physical and radiological examinations suggested a complete tear of the acl and tearing of the medial and the lateral menisci.The article describes the following procedure: arthroscopic acl reconstruction with autogenous gracilis and semitendinosus hamstring tendons was performed.The torn medial meniscus was repaired by using the inside-out technique, and the torn lateral meniscus was trimmed to create a stable border.The devices involved were: the rigidfix implant for the femoral fixation, while a bioabsorbable interference screw and a ligament staple for tibial fixation.Complications mentioned in the article were: one year and 10 months after the surgery, he was seen with a large, slightly tender mass at the lateral aspect of the distal thigh, which had developed 4 months before (figure 1).A physical examination showed mild joint effusion, and grade 1 lachman and grade 1 pivot-shift test result, or unchanged stability as compared with his previous visit.Plain radiographs revealed an osteolytic femoral tunnel dilatation, and an mri study disclosed an extensive cystic lesion with osteolytic femoral tunnel widening (figure 2).Arthroscopy demonstrated that the intra-articular findings were relatively clear without fulminant synovitis, which contrasted with extensive bony pathological changes at the femoral tunnel and substantial extra-articular fluid collection.The reconstructed acl was taut and covered by a synovial lining.Intraoperatively, two pieces of a broken rigidfix pin fragment were found inside the cyst.
