Patients with TB may have hypersensitivity phenomena like erythema nodosum, episcleritis, uveitis and Poncetâs arthritis. Clinically, TB arthritis has been classified into 5 stages. Stage I or the synovitis stage presents with soft tissue swelling, no bony lesion, localized osteoporosis, and outcome after treatment is excellent. Stage II is early arthritis with marginal erosions (one or more erosions or lytic lesion in the bone; discrete diminution of joints space). The outcome is good with only mild stiffness. Stage III is advanced arthritis with subperichondral cyst and loss of joint space. The outcome is fair with notable loss of motion. Stage IV is more advanced arthritis with joint destruction and no motion at the joint after treatment.
