Arthroscopic treatment of septic arthritis of the elbow.
OBJECTIVE
Septic arthritis of the elbow is a serious orthopedic concern associated with high morbidity and mortality rates, traditionally treated with open exposure of the elbow joint. This study was performed to describe the outcome of arthroscopic treatment of septic elbow arthritis.


METHODS
From May 2000 through January 2008, 12 patients with septic elbow arthritis were treated arthroscopically at the Mayo Clinic, Rochester, Minnesota, a large medical center. We reviewed the patients' medical records concerning variables such as history and clinical findings, previous elbow history, surgical procedure, cultured organism, and follow-up. Using the Oxford Elbow Score and the Mayo Elbow Score, we examined current level of pain, function, and social-psychological aspects. Six patients died before initiation of this study and were therefore only studied retrospectively.


RESULTS
Septic elbow arthritis without pre-existing elbow problems shows excellent outcomes after arthroscopic treatment, with scores for absence of pain, function, social-psychological well-being, and range of motion of 97.9%, 100%, 95.8%, and 100%, respectively. When elbows were treated arthroscopically within 2 days after the onset of clinical symptoms suggesting bacterial elbow arthritis, maximum scores of 100% were noted for all aspects. Positive elbow history before infection and reoperation were associated with poor outcome scores, with 62.5%, 85.4%, and 50% for absence of pain, function, and social-psychological well-being, respectively.


CONCLUSIONS
Septic elbow arthritis occurs often in the debilitated, immunocompromised patient. Arthroscopic intervention is a reasonable alternative to open treatment. In this small series, the acutely septic elbow was successfully treated in the majority of patients, although the overall patient mortality rate remains high.
