Rectus femoris
Origin: Illium and lip of acetabulumInsertion: Tibial tuberosity via patellar tendonAction: Flexes hip and extends knee
Rectus femoris is a muscle located in the thigh that forms part of the quadriceps muscles, along with the vastus lateralis, vastus medialis, and vastus intermedius muscles. It originates from the anterior inferior iliac spine of the pelvis and extends down the thigh to insert onto the patella and eventually the tibial tuberosity via the patellar ligament.
The rectus femoris muscle functions to extend the knee and to flex the hip joint, meaning that it assists in lifting the leg towards the upper body. This muscle is also utilized in walking, running, and jumping movements. As part of the quadriceps muscles, the rectus femoris is often targeted in strength and conditioning exercises to help increase overall leg strength and stability.
Injuries to the rectus femoris muscle can occur due to overuse, trauma, or improper training techniques. Common injuries include strains or tears to the muscle, which can cause pain and discomfort in the front of the thigh, as well as difficulty extending the knee or flexing the hip. Treatment for rectus femoris injuries may include rest, ice, compression, and physical therapy exercises to aid in recovery and prevent further damage.
