"Any of you lot of banged up geezers considered proper knee braces? "
Well this 48 year old banged up geezer has just had his third op on the 'good' knee. So in addition to knee braces I have found that and I like wide grippy footpegs that you don't slip off. I find wide pegs distribute my weight better. I can almost see the day when I'll have big Harley running board/footboards on my Montesa. Then all you young guys had better watch out.
I had an ACL (ligaments are now fixed in placed with titanium screws) repair and then fell over four weeks after the op and broke my knee cap. I was watering the plants and some water linked from the stupid designer zinc watering can ( you know the sort of trendy watering can you buy at garden centres) onto the floor. Bang I went down. Leg shot out in front and bent up. Which they are not supposed to do as a good strong knee cap should act as an end-stop. The first op had weakened the musculature and my knee cap broke cleanly in two. Of course the wife was out drinking with some girlfriends that night. Man, did she get as surprise when she came home. So now I always ride with knee braces and have bought a longer garden hose.
I used to use a foam padded sports brace with carbon fibre panels at the sides that stopped the knee twisting. But it tended to get quite hot. The next problem I found was that a good brace should also have some sort of knee-cap cup protection in addition to anti-twisting side structures. This is so that if you fall forward onto a rock which you will at some point (or if you clip the side of the garage while squeezing between the car and the wall while riding in to the garage standing up on the pegs so that your knee is now at the same height as the bolt on the garage door) the knee cap itself is protected.
The best brace I have found is by a US company called Asterisk. USD599 a pair so they are not cheap but they do stop the knocks. And there is precious little extra foam padding to add heat and make them sweat.
Anyway, as the surgeon said to my wife before I went under for the op, "pay for it with his credit card Mrs Brown and just think of the airmiles".
