Ultrasonography of haemophilic arthropathy

Imaging is an essential tool for evaluation and monitoring of haemophilic arthropathy. Ultrasonography is increasingly used for joint assessment, due to its great sensitivity for soft tissue and relatively low cost. To assess the joint status and the role of ultrasonography in routine diagnosis and monitoring of joint disease in cohort haemophilic patients. Findings of patients with haemophilia, who routinely underwent ultrasonography were retrospectively evaluated to assess their joint status and the role of ultrasonography in routine diagnosis and monitoring of joint disease. Out of 325 joints examined (115 ankles, 210 knees), ultrasonography identified damages in 50% of ankles and 33% of knees in overall 111 patients, aged 7-80 years (median = 29 years). Synovial hypertrophy and cartilage abnormalities were the most frequent observations (88% and 76% in affected knees, respectively). Pristine joints were more frequently found in patients on primary prophylaxis, young age or no bleeding in the year prior to examination. Furthermore, no concordance was found between presence of joint changes at ultrasonography, and clinical joint status. Ultrasonography was shown to be able to detect joint damage involving soft tissues and bone surface. Its use might allow frequent monitoring of patients with haemophilia and early detection of arthropathy. For these reasons it might represent a valid tool in the routine management of haemophilia.
