On your knees

A friend of mine had a unfortunate fall the other night and ended up dislocating his knee cap. He was in a rush, trying to catch transport and ended up taking a spill. As you can see below, the right knee cap is swollen and has moved up ruffly 2 to 3 inches into his thigh. Below that is a picture and diagram of the knee and surrounding muscles. You can see the severity of his injury.
Best of luck to my home boy. He has surgery really soon and should recover quickly. It looks a lot scarier and painful than it is. For someone who only sees bodies, this is kind of a surprise.
