The gluteus medius is a muscle located on the outer side of the hip, which is critical for abduction,  which is a lateral movement going away from your body. It supports movement such as squatting, getting out of a car, or climbing a set of stairs.

A torn gluteus medius may cause persistent pain that seems to mimic trochanteric bursitis. When physical therapy and injections into the trochanteric bursa do not provide any relief, a torn gluteus medius can be expected.

Most often, a torn gluteus medius may be repaired arthroscopically by sewing the torn part of the gluteus medius tendon back to the bone using small anchors. When caught within the first year, the procedure has a 90% success rate.
