Physical Impairment of the Day

I have been diagnosed with a "not bad" case of patello femoral syndrome. Short explanation: my knee sometimes hurts. Longer explanation: of the two major muscles running the length of my thigh which are responsible for stabilizing the kneecap, one is stronger than the other, resulting in unbalanced tension on my knee that can cause it to slip out of place. Simple physical therapy will correct it. However, in a worst case scenario, if the strength of the outside muscle approaches infinity and the strength of the inside muscle approaches negative infinity (what you might call infinite atrophy), then flexing my leg will result in my kneecap firing into the sky like a clay pigeon, whereupon an intrepid sportsman will rise up from a previously unseen duck blind and blast it with a shotgun.
