Cheers for the replies, surgery is inevitable if you continue to have severe pain in your knee into later life.
I had 2 ops by the age of 14, haha which fucked up my chances of playing for Liverpool (I was iivited by Geoff Twentyman for a school boy trial but one close up look at my patched up knee saw an abrupt chance of stardom!)
But, I still played footy in Sat/Sun Liverpool Amateur League till I was 50 plus and also for our very own Internet LFC team, so I got to wear the famous red jersey (of sorts!) eventually!
So, my knee led a good life but once arthritis kicked in it was time to get a new one, but I did wait until the pain was intolerable.
I tripped over in my flat the other night, haha chasing a mouse, my knee took the brunt of my fall and bent far more than it should at this stage, not without supervision anyway, so in real pain at the moment after that mishap.
I see my surgeon in 2 weeks and have 2 physio sessions before that, so hopefuly things will look better in a couple of weeks.
Also, the Hospital have suggested I join a Lifestyles Gym on a 12 week supervised course in the gym and pool to help my recovery along. I haven't done that yet, never been much of a gym or pool person, but will take their advice and join the gym near me on Gt Homer Street this week.
