Microfracture surgery is nothing to sneeze at. My surgeon told me this is the next step to fix the cartilage damage under my kneecap. He said he will have to drill a series of holes thru the cap to stimulate growth. I was told it is a minumum of 6wks in a cast and LOTS of therapy afterwards.
When I when in to have my knee scoped, I was told this may be needed, but I was also told all of the risks and post-op issues. I told the surgeon that I cannot afford to be out of work 6 weeks, so he just cleaned up what he could.
