Evaluation of Infection after Anterior Cruciate Ligament Reconstruction during a Short Period.

Author information

Department of Orthopaedic Surgery, Kyungpook National University Hospital, Daegu, Korea.



We encountered 7 cases (7.1%) of infection (5 deep and 2 superficial) in 98 cases of anterior cruciate ligament (ACL) reconstruction using hamstring autografts in a 17-month period. The aim of this study was to analyze the causes of infection and to introduce our treatment strategy.

Materials and Methods:

We investigated the shelf-life of the fixation implants, the order of surgery, previous knee surgery, infectious pathogen, treatment of infection, and results of treatment.


There was no problem with the expiration date of the fixation implants. The order of surgery was either the last or second to the last of all those performed on the same day. One patient had undergone knee surgery 8 months previously. The treatment after infection included aggressive debridement in all cases. Revision ACL reconstruction with graft removal was performed in 1 case of persistent infection with methicillin-resistant Staphylococcus aureus. All cases had satisfactory clinical results without recurrence during a mean 24.9 months of follow-up.


We could not verify the exact cause of the high incidence of infection during the 17-month period. However, preventive measures are important to decrease the incidence of infection after ACL reconstruction.
