Objectives: We aimed to discuss the correlation between the Hemophilia Early Detection Ultrasound in China (HEAD-US-C) score and the Hemophilia Joint Health Score version 2.1 (HJHS 2.1) of the knee joint in patients with hemophilia.
Methods: We included 70 male patients with hemophilia admitted to The Second Hospital of Shanxi Medical University; the patients' bilateral knee joints were evaluated using the HEAD-US-C score and HJHS. We analyzed factors influencing hemophilia arthropathy of the knee and examined the correlation between the HEAD-US-C score and HJHS.
Results: The joint injury severity was positively correlated with age and the number of bleeds (P < .001). Further, the HEAD-US-C score and HJHS differed according to the severity (both P < .001), but not type (P = .163 and P = .283, respectively), of hemophilia. There was a significant correlation between the HEAD-US-C score and HJHS (P < .001).
Conclusions: Overall, all joint lesions observed on ultrasound corresponded to clinical joint functional abnormalities. Therefore, the HEAD-US-C is important for hemophilic arthropathy evaluation and is useful in explaining abnormal joint function.
