Hi all,I am currently 3 months post-op from microfracture to the back of my patella. I'm concerned because I still haven't seen any improvement. In fact, the pain is actually worse now than it was pre-op. I did have less grinding for a while post-op, but now the grinding is getting worse again. Is this normal? My OS told me that my knee should be feeling noticeably better by 4-6 months post-op, but so far it's just getting worse. I am still going to physical therapy twice a week. I feel that my quads are getting stronger, but my knee is just not getting any better. My therapist seems to be perplexed and feels that I should at least being seeing some, even if slight, improvement.How do I know if the microfracture has failed? What are my options if my microfracture does, indeed, fail?~Erin~
