Knee Anterior Cruciate Ligament Injuries: Common Problems and Solutions.

Anterior cruciate ligament (ACL) reconstruction is one of the most commonly performed procedures in the United States. Although complications are rare in ACL surgery, failure to appreciate them can lead to significant patient morbidity in the short and long terms. More common complications in ACL reconstruction include tunnel malposition, infection, tunnel osteolysis, fixation failure, fracture, arthrofibrosis, graft site morbidity, and deep vein thrombosis or pulmonary embolism. Tunnel malposition is the most common technical error in ACL reconstruction leading to failure. Proper planning during the index surgery can help prevent these complications, especially when related to tunnel malposition.
