OBJECTIVE: To investigate the characteristics of ultrasonography in haemophilic arthropathy in knee joints. METHODS: The knee joints (n=135) of 68 patients with haemophilia A (n=59) or haemophilia B (n=9) were consecutively evaluated with ultrasonography and scored according to MELCHIORRE ultrasound score. The correlations between ultrasound score and the number of knee joint bleeding episodes, age, and World Federation Haemophilic orthopedic (WFHO) score were studied. RESULTS: 68 male patients with median age 20 (3-48) years old were enrolled in this study. The prevalences of hydrops articuli, fibrotic septa, synovial hypertrophy, synovial hypertrophy with angiogenesis, haemosiderin deposition were 39.2% (53/135), 3.0% (4/135), 77.0% (104/135), 49.6% (67/135), 37.8% (51/135), respectively; and the prevalences of cartilage damage, bone erosion, bone remodeling, osteophytes were 63.7% (86/135), 48.1% (65/135), 3.0% (4/135), 13.3% (18/135) respectively. The average ultrasound score was 5.21[95% CI (4.50-5.93)]. The ultrasound score of knees joints according to age 0-6, 7-18 and > 18 years old groups were 0.63[95% CI (0.15-1.10)], 2.88[95% CI (1.90-3.85)], 7.83[95% CI (7.07-8.60)], respectively; and the difference among groups was statistically significant (P<0.01). The significant difference of ultrasound score was not found among moderate, mild and severe haemophilia (F=0.90, P=0.914). A significant positive correlation between ultrasound and WFHO scores was demonstrated (r=0.745, P<0.01). The ultrasound score increased significantly with the increase of number of knee bleed Episodes (F=49.926, P<0.01). CONCLUSION: The main characteristics of ultrasonography of haemophilic arthropathy in knee joints were identified as followings: synovial hypertrophy, cartilage damage, bone erosion, hydrops articuli, and haemosiderin deposition. Ultrasonography was a fast, effective, safe, and available inspection method in assessment of haemophilic arthropathy.
