Knee Animation Help

Hey all… I’m in need of an animation of a side view for a knee project i’m doing. It needs to show the long term effects of being in a crouched position and how moving the knee once and a while gets the synovial fluids moving so that the cartilage is continually supplied with the fluid.

For one of the slides i need a close up animation of a knee that bends… I tried to get something working earlier but it ended up looking terrible. I’m wondering if there are any available fla files out there, i tried searching a few sites as well as google, to no avail.

If anyone has some kind of knee animation or knows of a good way to make the animation, let me know. Any help would be much appreciated.

Thanks in advance,
