As an avid and competitive golfer (150 rounds a year) my knees started hurting to the point I could no longer play without exceptional pain. I researched the breakthroughs Dr. Haas had achieved with his new artificial knees. I had my left knee replaced in 2011 and my right in 2013. I was playing in 12 weeks after each surgery. After my right knee was replaced I went on to win 6 straight Greater Area Philadelphia club matches in 2013-14 and placed runner up in our club's Thomas Huber Cup-- an extremely demanding two day event. Golf is now enjoyable and I am so very thankful I am able to play pain free and at a competitive level again.
