“Knee arthroscopy is not a benign procedure, and patients should be aware of the risk of complications,” the authors wrote in their study.
Matthew J. Salzler, M.D., and colleagues with the University of Pittsburgh Medical Center identified 92,565 arthroscopic knee surgeries in the American Board of Orthopaedic Surgery database and collected data on the treating surgeon’s geographic area, sports fellowship training status, patient age and sex.
According to the study abstract, there were 4,305 complications. PCL and ACL reconstructions had the highest complication rates (20.1 percent and 9 percent, respectively). The investigators also discovered that male patients had higher complication rates compared with female patients (4.9 percent vs. 4.3 percent) and patients younger than 40 years had a complication rate of 6.2 percent compared with a complication rate of 3.6 percent for older patients. Surgeons with sports fellowship training had higher complication rates (5.1 percent) compared with those who did not (4.1 percent). The rate of pulmonary embolism was 0.11 percent and this rate was not statistically different in patients who received chemical prophylaxis.
