There were multiple injuries to both knees that begin years ago.
 Seems like once I had the 1st severe injury to one knee, the other knee wasn't far behind.
 At 1 point I injured my good leg waiting for surgery on the damaged leg.
 I should have done this years ago but kept waiting for a better method.
 The technology is more precise but the surgery itself is still the same..
 I decided to cry once rather than spread it out over 2 separate surgeries.
 The surgical pain is there,  but the bone on bone pain is gone,  feeling good about it.
