I don’t have words to express what your Kneetrac has done for my mother in law, who by the time we arrived was literally in tears from the pain, anguish and so depressed I can only imagine what it must be like to feel that helpless. But what your kneetrac did was amazing, as soon as we put it on a million lights went on, she got up and walked as if she was dreaming. And yes she walked pain free, and she has stayed that way since, she has learned to put the brace by herself, remind you she is 83 years old and is a very happy lady, who can do her chores in perfect comfort.
