condyle has: - ✔✔increased in size

translation with respect to femur

translation with respect to femur
, ✔✔t/F: the two points of attachment for the medial collateral ligament are the distal
medial femoral condyle and the proximal fibular head - ✔✔false
✔✔with respect to the degrees of freedom of motion in the knee: how many are there? -
✔✔6

✔✔during the screw home arc of motion in the knee, the tibia will internally rotate with
reference to the femur as the knee extends - ✔✔false
✔✔t/f: since the knee joint requires little assistance from the muscles as it moves
through the screw home arc of motion, the resultant motion is described as "active
motion" - ✔✔false
