Mr. June Bug had partial knee replacement (the inside half) on Aug 1 and was really sorted out and on the bike after about two months or so. The physicians assistant gave numerous warnings about hitting it too hard too early and the realistic possibility of sustaining an injury in a fall and having to redo the surgery, based on her personal experience with hard-headed roadies and mountain bikers, but all was well this time around.

My sense is that they have a very good protocol in place to prevent infection; Mr. June Bug had no problems with infection this time around.
