What factors increase my chances of getting a blood clot after knee or hip replacement surgery?
Any major surgery, including hip or knee replacement, increases your risk of a blood clot, because surgery injures blood vessels. Blood vessel injury causes your body to make clotting factors, which are specialized proteins that form clots. Orthopedic surgery distorts your normal bone and muscle structure for a short time, and you may have difficulty moving around right after hip and knee replacement. All increase your risk of a blood clot. Go to http://www.stoptheclot.org/stoplight.htm for tools to assess your clotting risk.
