Knee infection is a relatively rare complication after arthroscopic knee surgery (Babcok et al., 2002), with reported incidences ranging from 0.1 % to 3.4 % (Babcok et al., 2002 and Bert et al., 2007). Although postoperative dental and surgical procedures were formerly considered a risk factor for infection in arthroplasty patients, the American Dental Association (ADA) and Academy of Orthopaedic Surgery (AAOS) no longer recommend prophylactic antibiotics for patients with prosthetic joints and do not make recommendations concerning patients who have recently undergone arthroscopic surgery (J.

Methods The records of all primary arthroscopic procedures car-ried out by the senior author (JD) between 2006 and 2012 were retrospectively analyzed. All postoperative infec-tions were tallied, and patients were queried about the following known risk factors for postoperative infections: remote body-site infections, open wounds, rashes, post
