The articular problems of hemophiliac patients begin in infancy. These include: recurrent hemarthroses, chronic synovitis, flexion deformities, hypertrophy of the growth epiphyses, damage to the articular cartilage, and hemophilic arthropathy. The most commonly affected joints are the ankle, the knee, and the elbow. Hematologic prophylactic treatment from ages 2 to 18 years could avoid the development of hemophilic arthropathy if the concentration of the patient's deficient factor is prevented from falling below 1% of normal. Hemarthroses can be prevented by the administration of clotting factor concentrates (prophylaxis). However, high costs and the need for venous access devices in younger children continue to complicate recommendations for universal prophylaxis. Prevention of joint arthropathy needs to focus on prevention of hemarthroses through prophylaxis, identifying early joint disease through the optimal use of cost-effective imaging modalities and the validation of serological markers of joint arthropathy. Screening for effects on bone health and optimal management of pain to improve quality of life are, likewise, important issues. Major hemarthrosis and chronic hemophilic synovitis should be treated aggressively to prevent hemophilic arthropathy. 1. Introduction Hemophilia is an inherited disorder of clotting factor deficiencies resulting in musculoskeletal bleeding, including hemarthroses, leading to musculoskeletal complications [1]. The pathogenesis of hemophilic joint arthropathy continues to be explored and there is evidence to suggest that iron, cytokines, and neoangiogenesis can initiate synovial and early cartilage damage resulting in molecular changes and the perpetuation of a chronic inflammatory state. This joint arthropathy has long-term consequences for bone health resulting in chronic pain and quality of life issues in the individual with hemophilia. Hemophilia has been recognized as the most severe among the inherited disorders of blood coagulation since the beginning of the first millennium [2]. Joint damage is the hallmark of the disease. Despite its frequency and severity, the pathobiology of blood-induced joint disease remains obscure. Although bleeding into the joint is the ultimate provocation, the stimulus within the blood inciting the process and the mechanisms by which bleeding into a joint results in synovial inflammation (synovitis) and cartilage, %U http://www.hindawi.com/journals/apm/2012/201271/
