The quadriceps muscles are primarily involved in knee extension.
The quadriceps perform knee extension, however, the rectus femoris, which is one of the 4 muscles of the quadriceps, also does hip flexion.
The three primary muscles active at the knee are the quadriceps, hamstrings, and gastrocnemius. The quadriceps, located at the front of the thigh, are responsible for knee extension. The hamstrings, located at the back of the thigh, facilitate knee flexion. The gastrocnemius, a calf muscle, also plays a role in knee flexion while assisting with ankle movements.

The antagonist muscle in the flexion of the knee is the quadriceps muscle group. When the knee is being flexed, the quadriceps relax to allow the hamstrings to contract and bring about the flexion movement.
The primary muscles involved in hip extension are the gluteus maximus and the hamstrings. The primary muscles involved in knee flexion are the hamstrings and the gastrocnemius.
The prime mover for knee flexion is biceps femoris, semimembranosus, and semitendinosus. The prime mover for knee extension is the Quadriceps â?? vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris
An agonist muscle is a muscle that plays a part in the extension of a muscle. The agonist muscles for a knee extension are the quadriceps and hamstrings.
The antagonists would be those muscles that cause knee flexion. Hamstrings (biceps femoris, semimembranosus, semitendonosis) are the primary knee flexors, and would thus be antagonists to knee extension.
The muscles involved in knee flexion are the hamstrings, gastrocnemius, and popliteus.
Vertebral Foraminal Entrapment on Hip Flexion and Knee Extension
The rectus femoris differs from the other quadriceps muscle in that it crosses both the hip and the knee joints. Thus, it causes both flexion of the hip and extension of the knee.
