TB Knee
Common site of osteoarticular TB after spine and hip; presents with chronic monoarthritis. Phemister triad on X‑ray: peri‑articular osteopenia, marginal erosions, gradual joint‑space narrowing. MRI shows synovitis, cartilage loss, and bone marrow edema—useful for early disease. Confirm by biopsy/AFB/GeneXpert; ESR/CRP typically raised. Treatment: ATT 9–12 months; synovectomy in persistent synovitis; arthrodesis/arthroplasty after disease quiescence for end‑stage joints.
