I was told the same thing...knee looks good (2nd opinion) so either continue with PT or do the exercises and stretching on my own. Weak muscles...same old same old. I had a sports medicine Dr. send me to vascular to check out the veins and blood flow and it was all good with some calcification which was normal for my age. I'm so tired of my knee and surrounding muscles being sore and hurting when I overdo. By two years you would think that things would be better and while they are from where I started I would almost rather deal with the prior cortisone shots but they were getting every 4 months or so and did the surgery. I even had one after my surgery around a year and it didn't help.
