Mild Hemophilia

Currently, few recommendations exist for patients with mild hemophilia, who represent approximately 60% of the hemophilia population. This study aims to provide objective data on joint health in these patients, which are currently limited compared to those with moderate or severe hemophilia. The use of joint ultrasound in mild hemophilia could allow early, asymptomatic detection of joint damage, support tailored management including patient education, and ultimately improve quality of life. The study will also explore the correlation between coagulation factor levels (FVIII or FIX) and other indicators of joint health in France.
