Prior to my operation I did the exercises that were recommended. It helped greatly in the recovery process as did the PT and post exercises. Don’t be afraid of the exercises they can’t hurt your knee. I had my surgery on Feb. 16th and on May 1st I was playing golf and officiating high school baseball. Dr. Goldman is a master of this operation. I only have a thread like scar on my knee that is barely visual a year after my operation. I’m looking forward to having my left knee done when the time comes. You couldn’t be in better hands.
