I’ve had 9 scopes on my knees. 5 on right and 4 on the left…..Shots help but they actually do long term damage. My advice is, if you have to ask; then you are not ready. JRF’s comment 100% agree with. I’m about your age and I know I have 2 replacements in my near future. Good luck whatever you decide and hope you can find some relief from something….it sucks
