Quote:The article is misleading about what Microfracture surgery actually is.  They say it helps the existing cartilage to heal, but in reality, the procedure is intended to develop new cartilage.  The problem is, it's not as forgiving as the real thing, so the joint is immediately an arthritic joint.  That's why many players who have the procedure have so many issues.  The swelling and pain are always going to be an issue.  The potential for follow up surgeries to repeat the process is pretty high.  It takes someone with a significant work ethic who is a dedicated rehab guy to get back anywhere close to normal, and Clowney is reportedly the exact opposite.
