Surgical management of septic knee arthritis with open arthrotomy and debridement-a case report

Abstract

<p>Septic arthritis is an inflammatory destruction of the native joint following inoculation of pathogen. Most common organisms causing septic arthritis are <em>Staphylococcus</em> and <em>Streptococcus</em>. Large joints are commonly involved with hip and knee joint accounting for approximately 60% of the total cases. Diagnosis is usually straightforward with the patient presenting with obvious local signs and symptoms along with toxic constitutional symptoms owing to the aggressive nature of the disease. Medical management in form of intra-venous antibiotics forms the mainstay of treatment but it is often required for a prompt surgical intervention in order to provide acute relief from symptom and also to decrease the disease load so as to save the joint from irreversible damage. We have a 63-year-old male patient came presented to us with a right knee swelling and tenderness of 3 weeks duration with restricted ROM with severe toxic constitutional symptoms of 1 week duration. Patient was planned for open arthrotomy and debridement and drainage of the pus and was started on an empirical therapy of injection piperacillin and tazobactam combination for 3 weeks. Immediate relief from symptoms following arthrotomy with good range of motion at 4 weeks post-surgery. As is clear from our case, an early diagnosis of septic arthritis and starting of appropriate antibiotics along with appropriately aggressive surgical interventions in the form of open debridement is the key for treatment of septic arthritis in order to save the joint from irreversible inflammatory damage. Surgical intervention not only gives immediate symptomatic relief but also decreases the load over antibiotics and increases local blood supply subsequently helping in better healing.</p><p><strong> </strong></p>
