Staphylococcus aureus is the most common cause of bacterial arthritis in all age groups.Prepatellar bursitis (septic) is seen in children with local cellulitis and often local trauma. Children will present with local signs of infection and preservation of joint function. Focus treatment on local aspiration and drainage and target antibiotics at S. aureus.Discitis presents in children most commonly with abnormal gait or lower back pain. Clinical improvement comes with early anti-inflammatory medications and antibiotics targeted at S. aureus and Kingella kingae.Clinical manifestations of infectious tenosynovitis range from pain with passive extension to tenderness along the tendon sheath. Management includes surgical intervention and antibiotic therapy.Osteomyelitis typically develops after a period of bacteremia and presents with fever and progressively increasing bone pain or limp. S. aureus is the most common cause of acute hematogenous osteomyelitis in children; however, K. kingae is increasingly identified in preschool-aged children with osteoarticular infections.
