I’m 6 months out from my knee replacement surgery with Dr. Matsen Ko. My knee is virtually as good as new now and I treat it as I normally would. I got back on my bike a week short of 2 months. Now I’m routinely riding over a dozen miles several times a week. I’ll soon be doing 20 miles on the Centennial Trail. Thank you Doctor, for helping an 86-year-old get back in shape.
