This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers are studying gene expression — the activity of genes in your cells — to find new markers that could help predict and prevent joint damage in people with severe hemophilia A or B. They will collect small tissue samples during routine joint surgery or arthrocentesis procedures, along with blood samples, to understand what's happening at the genetic level in hemophilic joints.
Joint damage is one of the biggest long-term problems for people with hemophilia, affecting up to 90% of patients over age 4. Even with modern treatments, joint bleeds can cause permanent changes to the joint lining that lead to arthritis-like damage. This research aims to find new biological warning signs that could help doctors better predict, monitor, and prevent this damage before it becomes severe.

If you qualify, you would participate by providing tissue samples during a joint procedure you already need for medical reasons — such as joint surgery or fluid drainage — plus a blood sample. Researchers will analyze the genes active in these samples to look for patterns linked to joint damage severity. The study compares your results with those from people who have other types of joint disease to identify what's unique about hemophilia-related joint damage.
