Hey, I know someone who had a similar injury. Here's the easiest way to fix it: you and your friend both lay down on the ground, he puts both his legs around your injured leg in a triangle by looping one of his legs inside your leg, then back over the top. Then he puts his foot into the bend of the knee of his other leg (it is important that he keeps his legs locked tightly around yours, to keep it immobile, otherwise this therapy won't work). Your foot should be along his side, tucked into his armpit. He then puts his forearm under the heel of your foot and then cranks his arm as quickly and as hard as he can up and towards his body. If this technique is applied correctly, it will quickly take care of your knee problem.
Best of luck, we all know how much knee injuries suck. Hope you heal quickly.
