Persons with haemophilia should not feel limited in their ability to participate in sports. After consultation with a physician or other health-care provider and with a proper understanding of the risks involved and the strategies for managing these risks, patients with haemophilia can - and should - enjoy physical activities. We have analysed numerous reports of sports injury statistics and used them to rank a variety of sports according to their degree of injury risk. In addition, we have developed a brief orthopaedic examination and a five-item fitness check that evaluates the level of physical fitness of patients with haemophilia. Using these tools, we can appropriately recommend specific sports activities best suited for each patient. In addition, we recommend that patients who regularly participate in sports maintain adequate levels of clotting factor through the use of regular prophylaxis. With proper physical evaluation and preparation, patients with haemophilia can realize the physical and emotional benefits of participation in sports.
