The target joint.
Bleeding into the joints is the most common manifestation of severe haemophiliacs. Although it may resolve spontaneously or with treatment, some patients find that one particular joint has recurrent bleeding; this is termed a target joint. Recurrent bleeding prevents the joint from regaining its range of motion, muscle strength and normal appearance. These changes become permanent, leading eventually to osteoarthritis. A target joint requires urgent and comprehensive treatment, especially in young patients, if permanent damage is to be prevented. Treatment with factor concentrate prophylaxis and physiotherapy can help to prevent new bleeds and allow the synovitis to resolve, but for persistent synovitis, synovectomy is recommended. The target ankle joint is a special challenge as it often develops in very young children when the articular cartilage is susceptible and compliance with conservative treatment is difficult.
