I've had partial on both knees. Best thing I ever did. Fucking agony for the first week or so but do the physio - even though it feel pointless, it isn't. Supposedly a 10 year life span, but I was relatively young at the time for such an opp - 43 when I had my first one done. I'm 53 now and the consultant said they were as good as new in my last check up a few months ago. I got to the stage I couldn't walk without crutches for about a year so they agreed to do them for me. I'm an ex semi pro football and cricketer so they took a pounding in my youthful days. Proper bandy legged now so the cartilage just wore away on the inside of the knees. I can still play astro turf football on them and they hold up really well. It's just the rest of my body which hurts like hell now after a game haha. Good luck mate. You'll be good. Just remember the pain passes - even though after the drugs wear off on about day 2 post opp you wont think so. An do the physio - most important
