Delayed Knee Locking after Complicated Anterior Cruciate Ligament Reconstruction Despite Good Stability Using A Bio-Transfi x

We describe a case of delayed cyst formation that presented as intermittent knee locking after complicated anterior cruciate ligament (ACL)reconstruction using a Bio-TransFix implant in a 21-year-old male patient. During femoral fi xation, we could not pull out the guide wire that was temporarily used for the femoral fi xation. However, stability was good, and the guide wire was not removed. Th is was shown to be a wrong type of fi xation in a later study. During follow-up, the patient was satisfi ed and stability was relatively good until 18 months post-operatively. From the 2nd post-operative year, he experienced intermittent knee swelling and locking and pain around the lateral femoral condyle. Follow-up magnetic resonance imaging showed a large cyst around the broken wire tip, but the reconstructed ACL was fi ne. KCI Citation Count: 0
