Postoperative Infection After Anterior Cruciate Ligament Reconstruction: Prevention and Management

Because septic arthritis after anterior cruciate ligament reconstruction is an uncommon complication, information on prevention strategies has not been extensively studied. Recommendations that can be made from the available evidence are as follows: (1) prophylactic intravenous antibiotics should be given preoperatively; (2) patellar tendon autograft use decreases the possibility of a postoperative infection; and (3) vancomycin presoaking of grafts is strongly recommended, especially when performing hamstring autograft anterior cruciate ligament reconstruction. When septic arthritis presents after anterior cruciate ligament reconstruction, early management is crucial to allow a satisfactory outcome. Accordingly, early clinical suspicion is the most important factor to achieve a timely diagnosis. The treatment of choice is arthroscopic lavage with intravenous antibiotic treatment. Graft retention, when possible, is important for obtaining better functional results.
