Hirt knee from trampoline

Patient: I was jumping on a trampoline about a week ago and when I landed I noticed a pain in my left knee there was no swelling or bruisingbut the pain has gotten worse. Every time I put weight on it or crouch down I’m in pain, also when I straighten my leg I’m in pain. I was just wondering what you think I did to it and if I should go and get it checked.
