Check your insurance for any of these guys! I've worked with the first four listed and would have no hesitation in referring any of my friends/family to any of them and like I said before, my mess called knees.

As for your complaint and description of what happened....could still be any number of problems both bony and soft tissue. With the knee wanting to "give out," there's a strong chance of soft tissue involvement, but with your description of the incident and the bony sound, you could just as easily have both. You could also have something called a tibial plateau fracture which can be deceptive little buggers. Trust me on that one - that's the break I had last summer.
