I have my right knee replaced April 5, 2017 and my left knee replaced October 17, 2017, both by Dr. Bjerke. The staff all took great care of me. I have had wonderful results. The best thing is that I can walk pain free. This winter I have been ice skating and cross country skiing. Overall a great experience. So very happy to be moving again. The only advice I have for anyone thinking about having this done is: BE PATIENT. It may take 2-3 months before you start feeling that it was worth it! But it is the most wonderful thing ever!
