Knee Stabilization: The popliteus plays a crucial role in stabilizing the knee joint, particularly during weight-bearing activities such as walking, running, and jumping. It helps prevent excessive rotation of the tibia and provides stability to the knee during movements.

Dysfunction and Knee Joint Issues: When the popliteus muscle becomes dysfunctional or experiences excessive tension, it can contribute to various knee joint issues. Here are some examples:

Hip Extension: The primary role of the gluteus maximus is hip extension, which involves moving the thigh backward from a flexed position. This action is important for activities like walking, running, climbing stairs, and standing up from a seated position.

Hip External Rotation: The gluteus maximus helps rotate the hip externally, which is the movement of the thigh away from the midline of the body. This motion is utilized during activities like kicking, turning, and lateral movements.
