Popliteus Muscle: Anatomy, Functions and Role

There are many muscles in the human body that perform important functions and provide movement in various joints. One such muscle is the Popliteus, also known as the Popliteus.

Anatomy of the Popliteus muscle:
The popliteus muscle is a flat, triangular muscle located at the back of the knee. It runs in the popliteal fossa between the lateral femoral condyle and the posterior surface of the tibia. The muscle has a short and wide belly, which connects to the tendinous process on the back of the femur.

Functions of the Popliteus muscle:
The popliteus muscle plays an important role in supporting and stabilizing the knee joint. Its main function is to flex the tibia and internally rotate the femur (medial rotation). When we walk or run, the popliteus muscle works together with other thigh and calf muscles to provide smooth movement and support to the knee joint.

The role of the popliteus muscle:
The popliteus muscle is a key player in extending the knee after flexion. When we bend the knee, the Popliteus muscle relaxes, which allows other muscles to make the flexion movement. However, when the knee is extended, the popliteus muscle contracts and exerts a control effect on this process, preventing excessive stress and maintaining the stability of the knee joint.

Injuries and problems with the Popliteal muscle:
Injury or dysfunction of the popliteus muscle can lead to various problems with the knee joint. For example, straining or straining this muscle can cause pain and discomfort in the back of the knee. There is also a risk of developing inflammation or tearing of the muscle if the knee is used forcefully and incorrectly, especially during sports activities.

Treatment and strengthening of the Popliteal muscle:
In case of injury or problems with the Popliteus muscle, it is recommended to consult a doctor or physical therapist for an accurate diagnosis and determination of the necessary treatment. Usually, conservative treatment methods are prescribed in such cases, including rest, physical therapy, stretching and strengthening of the muscle. Physical exercises aimed at developing the strength and flexibility of the popliteus muscle can help restore functionality and strengthen the knee joint.

In conclusion, the Popliteus muscle plays an important role in maintaining the stability and functionality of the knee joint. Its flexion and rotation functions promote smooth movement and prevent unnecessary stress on the joint. In case of injury or problems with this muscle, it is recommended to consult a specialist for diagnosis and treatment. Regular exercise and strengthening of the popliteus muscle can help maintain knee health and functionality throughout your life.



The popliteus muscle is a flat, triangular muscle that runs in the popliteal fossa. It is involved in flexion of the tibia and is located between the lateral condyle of the femur and the posterior surface of the tibia.

The popliteus muscle begins on the lateral surface of the tibia and continues downward, forming a triangular shape. It passes through the popliteal fossa and ends on the posterior surface of the tibia, next to the posterior tibiofibular ligament.

The function of the popliteus muscle is to flex the lower leg when it contracts. This occurs when walking, running, or other movements that require flexion of the lower leg. In addition, the popliteus muscle is also involved in maintaining the stability of the ankle joint.

To train the hamstring muscle, you can use various exercises such as calf raises, squats, lunges and others. It is important to remember that before starting any physical activity, you should consult a doctor to avoid possible injury.



Human muscles are like ladders along which our limbs continuously walk. Due to the motor muscles of the body, a person can walk, stand, and sit. This is a holistic system consisting of many muscle groups, each of which performs its own functions.

The popliteus muscle is a multi-joint muscle involved in the formation of three muscle groups: the posterior calf muscle group, the anterior calf muscle group and the anterior thigh muscle group.

With its help, the leg bends, facilitating walking and movement in space. The inner part of this muscle is called the medial head, and the outer part is called the lateral head.

The triangular planus muscle runs in the popliteal notch between the anterior edge of the deltoid muscle and the upper part of the tibial crest. Its lateral edge is attached to the posterior surface of the lateral condyle of the femur. The main action of the popliteus muscle is to flex the tibia at the knee joint. In addition, it is an integral part of a whole group of muscles, which provides a person’s entire life with the ability to move in space, jump and swing their limbs.
