Septic arthritis (SA) of the native ankle joint can result in serious morbidity and mortality but is a poorly quantified issue with little literature available on its clinical features, treatment and outcomes. This was a 10-y review (N ≥ 30) of adults with SA of the native ankle joint presenting to a single center from December 2009 to January 2019. Patients with prior ankle surgery, prosthetic infection, inoculation from trauma, not initially treated at our institution or lost to follow-up were excluded. Thirty-six patients met inclusion criteria. This is the largest cohort of adult native ankle joint SA in the literature. Mean age was 63.5 y (range 28-93 y). Patients most often presented with pain (91.7%), swelling (61.1%), and fever (22%). Staphylococcus aureus was the most common causative pathogen (63.9%). Readmission rate was 60%. The 1-y mortality rate was 14.3% with Charlson Comorbidity Index and age identified as independent predictors of mortality. No statistically significant predictors were found for returns to theatre. When assessing ankle pain in elderly patients, and those with poor physiology, high clinical index of suspicion should be maintained for this potentially life-threatening condition. We recommend development of evidence-based clinical guidelines for adult native ankle joint SA and establishment of a prospective multi-center database to enable further research in this field. |
