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, hemarthrosis 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
- Bruising easily
- Deep bruising due to bleeding in the muscle after routine shots or minor injuries
- Frequent nosebleeds
- 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
