Hi. I'm in Denver and have 2 surgeons lined up for questions. I'm 61 with 2 bad knees and at that point of knowing I should have one done but terrified of not be able to do what I can still do. Gardening, laying on my stomach to sleep, getting on my hands and knees when needed. Yet it gets harder by the day to get up and down from sitting. I feel like my legs are weaker by the day. I can still walk without pain but daily things are getting worse. My weight isn't getting any better either from little to no activity. What doctor did you use and do you recommend him?
