I was unloading some heavy supplies from my pickup yesterday, and I fell from it and hit the ground. Hard. From four feet up. I landed on my right foot, and I hard a loud crack, at the same time feeling my knee let go. Let me tell you, that is a special kind of pain.
I had one of the guys that was over drive me to the local emergency room. Four hours later, I left the ER in the knowledge that my leg was not broken, and a referral for an ortho. Having just gotten home from my ortho appointment, I can now tell you that I strained my patellar ligament.
I will be out of work for 4 to 6 weeks. Good thing I never take sick time, so I have plenty to spare.
