T84.50

Clinical Causes: Bacterial contamination during or after surgery Poor surgical technique or intraoperative contamination Hematogenous spread of infection from other parts of the body Failure of the body's immune response to control bacteria around the prosthesis Biofilm formation on the surface of the prosthetic material Material degradation leading to inflammation or susceptibility to infection

Key Symptoms: Pain and tenderness around the joint area Swelling and redness near the prosthesis Warmth or increased temperature around the joint Reduced joint mobility or stiffness Persistent or worsening joint pain Fever and general malaise in some cases Drainage or pus if a wound or surgical site is involved Persistent inflammation despite initial healing efforts

Diagnosis Path: Physical examination to evaluate swelling, warmth, and tenderness Blood tests such as erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and complete blood count (CBC) Imaging studies like X-rays, MRI, or nuclear scans to assess prosthetic integrity and inflammation Joint aspiration to analyze synovial fluid for bacteria, white blood cells, and other markers Microbiological cultures to identify specific infective organisms

Treatment Protocols: Antibiotic therapy based on culture and sensitivity results, administered either orally or intravenously Surgical intervention such as debridement (cleaning of infected tissue), removal of the prosthesis, or staged revision surgeries Use of anti-inflammatory medications to reduce swelling and discomfort Regular monitoring and follow-up to assess treatment response and prevent recurrence In some cases, long-term antibiotic suppression may be necessary if the prosthesis cannot be removed Rehabilitation therapy to restore joint function after infection control measures
