Mine was in August. Was told by PT and Doc that scar tissue is your body's way of protecting a 'hurt.' It may take 1 to 2 years to convince your body that you don't need 'protecting' as much. Break it up EVERY DAY. Move it constantly; little even helps (like 1 inch swinging it back and forth). My scar tissue has slowed down and now I deal with the muscle that runs from your hip over your quad, ACROSS THE KNEE CAP, tightening up and pushing down on the knee cap. That really hurts; we stretch it out at PT more than bending. I stretch it out across the bed, the couch, as I walk, etc. See anatomy pics to get a clearer pic of what is happening. Swelling in the quad hurts the knee cap. This pain is due to me actually beginning to live my life; sometimes I overdo it. Even walking too much without a cane an trigger huge pain in kneecap area. So now NAPROXEN helps (tylenol not quite strong enough) but don't need opioids as it isn't nerve pains, it's pressure on kneecap. So keep going to PT and stretch those quads every few hours just like you did ice in the beginning. It may take 1 to 2 YEARS. Hang in. Learning as I go.
