[Intraarticular lesions associated with tibial fixation during anterior cruciate ligament reconstruction]

Anterior cruciate ligament reconstruction is a demanding procedure; complications may arise at any of its stages. This is the report of three cases in which the tibial fixation devices (IntraFix and Bio-IntraFix) led to intraarticular lesions. The complications were detected in one of the cases while the patient was still in the operating room and in the remaining two during the follow-up. All the patients had a stable knee, but all of them sustained chondral lesions resulting from the inadequate placement of the implants used for tibial fixation. Several suggestions to avoid the complications stemming from these devices are provided.
