Ask a question

Definition

The popliteal muscle is a muscle found in the leg, localized behind the knee joint. The popliteal muscle resembles a triangle that is attached to the tibia and femur, passing into the knee cap. The popliteal muscle is innervated by the tibial nerve. It is responsible for the internal rotation and flexion of the leg, as well as the stabilization of the knee joint during rotation. Arthritis and tendinitis are common conditions affecting the popliteal muscle, often caused by its rubbing against the knee.
