The following reasons are common for walking outwardly: First, congenital factors or improper posture: congenital factors or insufficient muscle strength in the lower limbs and incorrect posture of the patient when walking can lead to an outwardly oriented gait, which affects the patient’s normal life. Second, gluteus contracture: gluteus maximus, gluteus medius muscle injection drugs or trauma, resulting in local adhesions, muscle necrosis, fibrosis, the formation of muscle contracture scar, affecting the function of the gluteus muscle and daily movement. Patients may exhibit an outward-looking gait, inability to cross both lower limbs normally, inability to close the knee joint, positive squat test, positive single-leg straight-leg raise test, and the gluteus muscle may be hard to the touch and have local collapse. If the hip muscle contracture is present, surgery should be considered.
