Surgical Management of Septic Arthritis.

Lameness related to synovial infection needs to be addressed promptly because rapid degradation of the synovial homeostasis results in permanent cartilage alterations detrimental to complete recovery. Diagnosis is based on clinical signs, synovial fluid analysis, and imaging. Commonly affected joints are the fetlock, carpus, tarsus, and stifle; shoulder, elbow, and hip may also be infected. Knowing the source of infection is essential in cases of remote septic arthritis. Antimicrobials should be administered; local delivery systems may be used. Therapy relies on the removal of inflammatory mediators. Pain management is critical throughout the surgical procedures and the recovery period.
