The human body is like a complex machine that is able to adapt to all sorts of environments. No matter whether you want to run an ultra-marathon or climb the highest mountain on earth, the body will find a way to adapt. The only problem with this wondrous machine is that there is no manual. There’s no one book that gives all the answers about what to do if things aren’t the way they should be. Concerning knee pain this means that finding and fixing the problem can sometimes be tricky and to understand pain, you need at least a basic understanding of anatomy.
