Jeez, what'd you do to it

I thought tearing the cartilage on my left knee 3 times was bad enough! 
2 knee recos. 1st was when I was 16. Hit by a car at the age of 13. Last operation they had to remove a large chunk of cartilage. 30mm long, 15mm wide, 8mm thick. It locked my knee in a bent state and couldn't straighten it. Was limping around site for 3 days, till I decided to go to Moree hospital the next day for an xray. Once I'd seen the xray image, and got the you can't drive message, (wasn't my first rodeo driving, but a hella drive) I had a bigger problem, how do I get my work trailer and get home when the site was on
black soil and had been raining. After deflating the tyres and a lot of right foot , I was on my way home. Fueling up when needed too. Was glad to be home in the end. Few rum cans and some good meds works wonders.
Then the next problem came, my surgeon had retired a few years beforehand. Bugger. New surgeon from within the same group. Melbourne Orthopaedic Group. Month later and 10k poorer and 1 month recovery, the longest ever, was given the green light to work again.
Normally that type of surgery I'm walking the next day, I've had plenty of them.
But what's weird is that the knee doesn't feel like it has in the past, I can lift my heal off the ground when laying flat. Something I've never done since the accident.
I do know when I do need to have the knee replacement, my current work will cease. Office environment won't suit this tradie, I'm too vocal

so it'll be a forced early retirement
But what makes me smile is when
