shock
deepen the articular surface of the tibia

26
Q

knee joint: movements: the main movements? (2)

knee joint: movements: when the knee is flexed, some _ is also possible

A

rotation (hamstrings and popliteus are most important)

28
Q

knee joint: movements: if the knee is fully extended w/ the foot on the ground, the knee passively “locks” due to _ rotation of the _ on the tibia to produce a solid column (the lower limb) for weight bearing

A

medial rotation of the femoral condyles
