While playing racket ball the sole of my shoe stuck to the floor causing my ankle and
knee to slide outward. I felt my
knee buckle. I am not experiencing any
pain unless I twist my
knee. There is a small bulge on the outside of my knee cap. No popping noising when I bend my knee, it is hard to totally bend due to tightness from the swelling. I can put weight on it, but having to be really careful walking due to any twisting motion causing pain.
