I have been wearing braces for about 4 years and my knees are giving me trouble. My phisicist watched me walk and noticed my knees were trying to bend in the wrong direction. (know there is name for this) He wrote me a perscription for new braces that will correct this. He said they would make me walk with the knees very slightly bent. If you walk with your knees slightly bent, it corrects the knee problem. Check out your braces!!!!
