More than four years ago I had an encounter with a rabbit hole and have had a slightly dodgy knee ever since. My medical friend recently diagnosed it as a weak posterior cruciate and advised me to strap the knee in a certain way whenever I run, to give it the support that the knackered ligament can't. I was just wondering if anybody had experience of this or could offer any other advice. I have no intention of stopping running, but I'd like it to be as pain-free as possible and I want to minimise the chances of doing further damage. Any thoughts appreciated!
