Hi English Kid,
Is your knee well enough to play competitive basketball again?  Sounds like no... I was a competitive athlete in high school in basketball and soccer and played some club soccer in college.  (Nowhere near your level)  Had microfracture last May or so...about 19 months ago.  I followed all instructions and all rehab.  My muscle on my injured knee (the right one) is in pretty good shape...like I said I followed all instructions and worked hard.  I can do weight lifting exercises pretty well...nowhere near pre-surgery strength. yet but improving.  I have pretty much given up any type of agressive sports though. My knee cant take any pounding at all: running, light box jumps, or even just shooting baskets.  A couple of days ago I did some fairly light shooting around at the gym....dribbling, jump shots, you know something I wouldnt even have considered a workout before.  My knee has been sore and swollen for 4 days.  I pretty much have given up... maybe I am just a wimp...but I feel like maybe I am lucky just to be able to walk without pain. 

Does anyone know.... Am I making my knee worse every time it hurts like this?  Pain is usually the way the body tells you to quit doing something.  I guess I could take the pain though if I knew I wasnt risking damaging it worse.

At 19 months could I still be healing more or is it done at this point?

Should I just give up on activities like basketball or is there something that can be done about this?
