Hi there, You are a brave soul. I had my right knee replaced on 1-23-2019 and just like you, my other knee is taking a beating. I know I'll need it replaced but considered a couple of things you might want to consider before scheduling your other knee. 1: How many outpatient days do you have in a calendar year? ( also inpatient in case you need it and outpatient) 2. Understand that every surgery is different even if it's done by the same surgeon, in the same hospital, and on the same person. Your TKR might have been easy sailing but the left may cause you a bit more of a headache! Do you have enough rehab to cover what you'll need? I would say as soon as you go over everything regarding insurance and feel confident that the right knee is recovered, schedule your other one. I plan on getting cortisone shots until next year. I've never had them so I feel they should help until I reach a new calendar year for insurance's sake. How is your 4th week doing? Thursday will be week 7 for me and I am just now transitioning to a cane and my ROM is 0/110. Not great but we're working on it.
