both joints are uniaxial hinge joints, ginglymus if i'm not mistaken,
(meaning one degree of motion - flexion/extension). however the knee
joint does not articulate as tightly as the elbow. that's why the knee
joint contains menisci to shape the articulating bones for a better
fit/match to increase stability. i wise move in a weight bearing joint!
in fact the femur slides forward on the tibia briefly before flexion of
the knee (or is that extension? i forget the details this late in the
evening.)
hope this answers your question. just taught a course on joints last
semester so if you need more info let me know.
