Why is complete dislocation of the knee so rare?

Tendons anchor the cap top and bottom, keeping it pretty well in place. One can dislocate it to the side, but most injuries won't snap either tendon to the point the cap completely dislocates.

A bit more info...the tendon running from the bottom of the cap to the shin bone is used for graphs in repairing torn ACLs if one from a cadaver is not used.

because the knee joint is totally surrounded by 4 ligaments holding it in place.there's one on the front,at the back and on both sides
