3 months later and not much better

I had a bucket handle tear. The doctor did not repair it, only trim it during Artheroscopic surgery. He also found arthritis and had to "scrape the bones". There were fragments of bone behind the knee cap as well. Sugery was done April 22, I had PT 3 times a week for a couple of months. I still experience stiffness, some pain, cracking sounds , swelling and now have noticed swelling in my ankles , which I never had. I was discharged from PT since they could not help me any further and told to just keep doing the exercises. Am I being impatient, and what about the ankle swelling? Thanks for your opinion.
