I need help to know if I should go to my clinic or hospital to see if I broke my knee/leg or not. I am 300 pounds, and jumped off the back of a 1-2 foot tall truck. Stupidly I put more pressure to my right leg. I haven't had any bone- type damages before. It has a pain right underneath of the kneecap, I think it pushing the shin into the other bone, the thigh. It hurts when I walk on it, if I stand on it too much, it sends a spike through me of pain and I jerk. I can move it just fine, but if I pull it back too much or extend it while sitting too much it hurts.

Hi Michael

It sounds to me like you may have done some damage to your right meniscus (knee joint cushion... see image). I can't be sure if you damaged the inner (medial) or the outer (lateral) meniscus, but your signs/symptoms suggests a simple bruise or a minor tear to me.

If you had broken the large bone or fractured the condyles you probably would have pretty severe swelling and wouldn't be able to stand on the leg at all... ;)

I'd give it a couple days and see if the pain begins to resolve. If it does then you just stay off the leg as much as you need to and you should be fine within a couple weeks.

If the pain continues to bother you after a couple days go to to the hospital and have the knee joint looked at... may be a tear that needs to be repaired.

Good luck!
