Thanks for the reply! I am havig arthoscopy with abrasion chondroplasty, well that is what my surgery admit papers say. The abrasion chondroplasty is what has me concerned, I read it is when they chisle away and expose some of the bone to make it bleed, this should trigger the healing process and cause scarr tissue to form over the bone to act as a cushioning for the bones. My OS didn't explain this to me at all, it is just on my admit paper. He said he was doing a debridement under my patella. (knee cap) Reading that has me really concerned about recovery.
