- Option AOption BOption COption DOption EDr. Mithoefer is a top-notch surgeon that is cutting edge. He used a new surgical technique on my knee to regenerate my own cartilage rather than replacing it. I was able to get access to this futuristic technology by being part of a study years before it is going to be available on the market. My knee is doing really well and l am so impressed with Dr. Mithoefer’s skill and compassion throughout the entire process. He has my highest recommendation.
