Bacterial arthritis in the elderly: an overview

The key to successful treatment of acute bacterial arthritis is early diagnosis and initiation of empirical antibacterial therapy. Treatment includes antimicrobial therapy, debridement of the infected joint and treatment of pain. Empirical antibacterial treatment should be re-evaluated as soon as the causative pathogen is identified from joint fluid and other cultures. Mobilisation with partial weight bearing is encouraged early during treatment. The outcome of properly treated bacterial arthritis in the elderly is generally favourable and at least 50% of patients may recover without developing secondary osteoarthritis.
