Which muscles are primarily involved in medial/internal rotation of the hip?

The muscles involved in medial or internal rotation of the hip primarily include the tensor fasciae latae (TFL), gluteus medius, gluteus minimus, pectineus, and adductor longus.

The TFL plays an essential role in stabilizing the hip and allows for internal rotation, especially when the hip is flexed. The gluteus medius and gluteus minimus are critical for hip stability and are primarily responsible for hip abduction and internal rotation. These muscles work together to control movement and stabilization of the pelvis during activities such as walking and running. The pectineus, although primarily an adductor, also assists with internal rotation due to its anatomical positioning. The adductor longus, while mainly functioning to adduct the thigh, also contributes to medial rotation when the hip is in a specific position.

Understanding this muscle group is vital for recognizing their roles in hip pathology and rehabilitation strategies, as imbalances or weaknesses can lead to compensatory movements, such as lateral pelvic tilt or increased stress on the hip joint.
