    Surgical Techniques

    Arthroscopic or Open Drainage

    Emergency procedure to drain infected fluid from the hip joint. Can be performed arthroscopically (minimally invasive) or through open surgery depending on severity.

    When it is used

    Suspected or confirmed septic arthritis: assessment is urgent. The choice between aspiration, arthroscopic drainage and open surgery depends on age, the joint involved, the clinical picture, the causative organism and any bone involvement (osteomyelitis).

    Recovery

    Antibiotic therapy started early, with route and duration decided together with the infectious disease specialist based on the organism, the clinical response and inflammatory markers. Early mobilization encouraged.

    Postoperative Overview

    Septic hip arthritis is an orthopaedic emergency: it must be suspected, assessed and treated rapidly. Outcomes depend largely on how promptly it is recognised and treatment is started. With prompt treatment most children recover without long-term sequelae. The course described below is an indicative pathway.

    Recovery Pathway (indicative)

    Note: This is an indicative pathway, personalised after surgery. Some elements are relatively stable (goal of the procedure, approximate hospital stay, presence of a cast or brace); others depend on the individual case (weight bearing, range of motion, imaging, sport, hardware removal, follow-up intervals) and on the surgical technique chosen.

    1. Hospital stay

      Hospital stay of a few days. IV antibiotics started early and continued according to the clinical course and inflammatory markers.

    2. First weeks

      Hospital stay with antibiotic therapy and gentle range of motion exercises. The switch to oral therapy is decided by the infectious disease specialist based on the response.

    3. Second month

      Continuation of therapy according to the agreed schedule. Progressive recovery of hip mobility and strength, with rehabilitation if needed.

    4. Third month

      Gradual resumption of full activity. Monitoring for avascular necrosis (rare complication).

    5. Return to sport

      Indicative pathway: return to sport generally occurs some weeks after completing therapy, with normalised inflammatory markers and a reassuring clinical and radiographic picture.

    6. Follow-up

      Close follow-up during therapy, then spaced checks during the first year to monitor for growth disturbance or avascular necrosis. Intervals are personalised.

    Possible Complications

    With prompt treatment the prognosis is generally good. Delayed treatment increases the risk of growth plate damage, avascular necrosis, chronic arthritis and limb length discrepancy.
