Now this next piece I want to share with you is VERY VERY important, so pay extra close attention. Even though you got the x-ray back and there was nothing wrong with the bones in your knee there still may be issues with “soft tissue,” meaning tendons, ligaments, or cartilage that an x-ray is not necessarily going to pick up on. So as you are walking you will want to watch for your knee “locking” or “giving out.” This is a sure sign that you are having problems with the attachments in the joint. It is definitely best to go see an to check the knee out further to be safe.
