Wishing you a speedy recovery @Avedis53 Are you having a scope done or sometime more involved? I had my left knee scoped in 2015 and then flew to Hawaii. I wanted to climb a volcano while we were there, but my wife put the kibosh on that haha. Forget which one it was but it had a narrow set of steps. I was probably a week out from surgery and did an 8 mile hike on the north shore. It wasn't a bad recovery, but I didn't have anything major done, just some cleanup work.
