I broke my kneecap in three pieces. After immobilization, the xray looks good but there is still considerable swelling above the knee and I cannot fully bend it. (I was too embarrassed to tell the ER that my shoe had been untied and the lace caught in the door when I closed it, running to my car. I flew forward and crushed my knee but am afraid I may have ripped a tendon or muscle) The swelling hasn t gone down since the injury. I m allowed to walk some without the immobilizer but I can tell the muscle is only connecting at certain angles....
