It is now six months after my knee replacement and to date I have played 25 rounds of golf. I had my surgery in January and played my first round of golf 7 1/2 weeks later. I was very diligent about my physical therapy, which OSC provided in their office, and count that, plus an excellent surgeon for that success. I continue to be diligent about my exercise routine. The staff and office personnel are very friendly and helpful. A great experience!
