Postoperative infection resulting from arthroscopic anterior cruciate ligament (ACL) reconstruction is rare. We reviewed cases associated with infection after ACL reconstructive surgery. We have performed 261 ACL reconstructions using hamstrings between September 1997 and January 2002 at out hospital. We observed 4 (1.5%) knees with postoperative infection. All patients had Staphylococcus epidermidis of the knee joint. Three patients underwent arthroscopic debridement. All 4 patients healed from the infection without removal of the ACL graft and achieved improved stability in the operated knees.
