After 50 years of golf and skiing. I thought my world had come to an end, when my left knee became very painful and limited very much my sporting activities. I was 77 years old and luckily I heard about Mr Dunkow from friends at the golf club and how he had quickly transformed their lives. I visited Mr. Dunkow’s surgery in spring 2017 and promptly told off delaying my visit for too long. I had a total knee joint replacement in August 2017 and happily to report that I was skiing in the Austrian Alps 5 months later, fantastic. The big secret is to choose a great surgeon and build up the muscles BEFORE the operation. I am now 82 years old and still skiing and golfing due to the skill of Mr. Dunkow for which I’m so grateful for.
