A 16-year-old male who had undergone 6 months before an anterior cruciate ligament (ACL) reconstruction with an autologous hamstring graft fixed with a suspensory fixation device (XoButton device; ConMed Linvatec, Largo, FL), complained of a slightly painful mass in the distal posterolateral aspect of the thigh. The knee was otherwise stable. A 79 × 60 × 17 mm multilobulated tumor surrounding the implant device was observed in magnetic resonance images. The revision arthroscopy showed an intact ACL graft. The tumor was excised through a longitudinal posterolateral approach. It had a myxoid appearance. The undamaged implant was also removed. Two months after surgery, the patient was already asymptomatic. Althoughmost fixation device problems occur in the perioperative period due to an inadequate technique which may lead to graft instability, this case reminds clinicians of the possibility of later developing clinically relevant complications with suspensory fixation devices. © 2012, Thieme Medical Publishers.
