A new, exclusively radiologic classification of hemophilic arthropathy is based on a review of 54 patients who had had repeated radiologic examinations of all great joints before the institution of any specific treatment. In terms of a score, the severity of the arthropathy may be assessed in a single joint, in a single patient, or in a group of patients. Using the score system, the natural course of hemophilic arthropathy demonstrated that the severity of the arthropathy increased with age and degree of coagulation defect. All patients over 5 years of age with severe hemophilia were affected and the radiologic changes were progressive. There was a good correlation between the radiologically assessed severity of the arthropathy and the clinical findings.
一种全新的、专门针对血友病性关节病的放射学分类方法，是基于对54例患者的回顾性研究得出的。这些患者在接受任何特定治疗之前，均对所有大关节进行了多次放射学检查。根据一个评分系统，可以对单个关节、单个患者或一组患者的关节病严重程度进行评估。运用该评分系统，血友病性关节病的自然病程显示，关节病的严重程度随年龄和凝血缺陷程度的增加而加重。所有5岁以上的重度血友病患者均受到影响，且放射学改变呈进行性发展。关节病的放射学评估严重程度与临床 findings 之间存在良好的相关性。
原文中“clinical findings”直译为“临床发现”，但在这里结合语境意译为“临床表现”可能更合适，不过题目要求不添加任何解释或说明，所以保留了英文。
