The knee is OK, considering it's been there since 2002.  One rotator was also an injury and it was a painful recovery, but that was in 2005, so no complaints there.  The other one, the Doc said was bone spurs but they told me it was a rotator, in the recovery room.  Not good news, but also just wore out, so relatively easy recovery on that.  The first achilles happened just walking down a steep hill.  I thought it was a pulled muscle, but finally had an Ortho Doc look and he confirmed that it was torn.  Got a walking boot after surgery, with about 7-8 wedges in the heel.  Every week, or so, he would take a wedge out, till, i was down to flat again.  So, I have my Ortho stories, but all have had happy endings.  Sometimes you just have to give in to the calendar, and get'erdone!
