The Knee Unlocking Muscle
An odd place that raises eyebrows when experiencing pain in this area is the posterior knee compartment. There are structures in the back of the knee that are frequently associated with posterior knee pain. One of the involved structures is a small muscle called the popliteus. This muscle is triangular in shape and has what is called a ‘reversed orientation’ (1) meaning the muscle belly inserts distally and the tendon originates proximally.
Issues may arise when the popliteus lacks the mechanism of ‘unlocking’ the knee joint.
