Damn Ian, what a bastard of a thing.
I had three knee ops before I was twenty, two of them disasters (one had a major hemorrhage in joint after), and I've spent way too much of my life already crippled and agonised by knee injuries, so I can emphasise very strongly...
I hope the recovery goes well.
Getting round your place in your state must be interesting...
barely enough spare space to swing a cat if I remember correctly
I wonder if kickstarting that old thing after this is ever going to be stress free
Good luck, keep up with those bastard exercises and push through that pain.
