Quizplus · Accepted Answer

The muscle that medially rotates and flexes (unlocks) the knee joint is the popliteus. It attaches to the lateral condyle of the femur and lateral meniscus, and inserts on the tibia. Its action is to medially rotate the tibia on the femur, and to flex the knee joint. It plays an important role in unlocking the knee joint from a fully extended position.
