Low-level laser therapy for knee bleeding in children with hemophilia

This study is testing photobiomodulation (also called low-level laser therapy or LLLT) as an addition to standard hemophilia treatment for children who experience bleeding into their knee joints. The treatment uses a special laser device applied gently to the skin over the knee to see if it can reduce pain, swelling, and joint damage. Researchers will measure how well the treatment works by tracking pain levels, how much the knee swells, and how well the knee moves.

Knee bleeding is one of the most common and painful complications in children with hemophilia, often leading to long-term joint damage and reduced mobility. While standard treatments like clotting factor replacement help, doctors are looking for additional, non-invasive ways to reduce inflammation and help joints heal faster.
