Hemophilic arthritis, commonly caused by hemophilia, is characterized by repetitive bleeding into joints (hemarthroses) leading to progressive joint damage. It most often affects young males between ages 3-15, with the knee being the most common site. Bleeding occurs due to minor trauma in patients with deficiencies in coagulation factors VIII or IX. Physical therapy can help reduce pain and swelling through modalities like kinesio tape, TENS, manual techniques like stretching and mobilization, and proprioception training to prevent further joint damage. Surgeries like synovectomy may be considered if bleeding is recalcitrant to medical management.
