Question 34

closed chain - to "lock" knee

Answer 34

to lock the knee, the femur medially rotates on fixed tibia to allow quads to extend the knee

Question 35

closed chain - to "unlock" knee

Answer 35

to unlock the knee, POPLITEUS CONTRACTS, the femur laterally rotates on fixed tibia so flexion can happen

Question 36

open chain - to "lock" knee

Answer 36

the knee locks by laterally rotating tibia on fixed femur to allow quads to extend

closed chain - to "unlock" knee

Answer 37

the unlock knee, POPLITEUS CONTRACTS, medial rotation the tibia to fixed femur so flexion can occur
