Loose body following cross-pin fixation for anterior cruciate ligament reconstruction

We report a case of loosening of a bioabsorbable cross-pin fixation device for anterior cruciate ligament reconstruction. Forty-two months following a bone tendon bone reconstruction of the anterior cruciate ligament, the patient presented with a subcutaneous collection in the medial side of the kne...

Summary:We report a case of loosening of a bioabsorbable cross-pin fixation device for anterior cruciate ligament reconstruction. Forty-two months following a bone tendon bone reconstruction of the anterior cruciate ligament, the patient presented with a subcutaneous collection in the medial side of the knee. At subsequent surgery, a RIGIDFIX cross-pin fixator (Mitek, Westwood, MA, USA) was retrieved, intact, from the sterile fluctuant mass around the superomedial aspect of the knee. The graft was stable both radiologically and clinically, and the patient remains symptom free. This case raises concern about the use of this smooth cross-pin fixator and the consequences of backing out and the resultant intraarticular loose body. We suggest consideration of a loose body if the patient becomes symptomatic postoperatively, and early intervention to prevent chondral damage is recommended.
