When you straighten your leg, the quadricep muscles pull on the quadricep tendon, this pulls the kneecap to make the knee extend. When you bend it, the hamstring muscles contract and pull the tibia backwards, causing the knee to flex.

Answer:
The popliteus muscle at the back of the leg unlocks the knee by rotating the femur on the tibia, allowing flexion of the joint. The quadriceps femoris muscle group (rectus femoris, vastus lateralis, vastus medius, and vastus intermedius) crosses the knee via the patella and acts to extend the leg.
