Functional Assessment of Arthropathy—An International Perspective

Treatment of hemophilia aims to minimize structural damage to joints and maximize patients’ functional independence and quality of life. From an orthopedic perspective, treatment efficacy can be judged by quantifying the extent of musculoskeletal damage. Joint scores—both clinical and radiologic—have traditionally been measured in patients with hemophilia. However, such scores may lack the sensitivity to detect early changes in the hemophilic joint, and this has prompted the development of more sensitive measures. In addition, scores based on the status of individual joints do not consider the impact of arthropathy on overall musculoskeletal function. It would prove valuable to understand the implications of small differences in clinical/radiologic scores in terms of overall musculoskeletal function and patients’ quality of life. The development of functional scores such as the Functional Independence Score for Haemophilia (FISH) and the Haemophilia Activities List (HAL), along with the quality-of-life (QoL) measurement tools, have helped to provide a more comprehensive assessment of health in hemophilia. Such improved understanding should assist with the development of contextually relevant guidelines for the management of hemophilia.
