Hemarthrosis happens when there is bleeding into a joint.
Hemarthrosis is a condition where there is bleeding into a joint due to a complication, such as a blood disorder or a traumatic injury to the joint. The most common places hemarthrosis occurs are the knees, ankles and elbows.
Most cases of hemarthrosis happen after a traumatic injury to the joint. If your child has hemophilia or another blood disorder that affects blood clotting and makes them bleed more easily, hemavrhrosis may happen after a minor injury, such as falling down or bumping into an object.
Your child is more at risk for hemarthrosis if they have a blood disorder, such as hemophilia. In addition, if your child is taking a blood thinner, such as warfarin, they are more at risk for hemarthrosis.
Symptoms of hemarthrosis may include:
Bleeding gums after brushing teeth or dental work
Bleeding longer or more than usual after injury or surgery
Blood in the urine
Deep bruising due to bleeding in the muscle after routine shots or minor injuries
Joints that feel warm or have a tingling sensation
Pain and swelling at the joint
Prolonged bleeding in babies after the umbilical cord is cut or after a male is circumcised
Refusal to move an arm or leg because of joint pain
