A thigh lift is performed to remove excess skin and fat from the upper legs. Candidates typically suffer from loose, inelastic skin after extreme weight loss due to diet, exercise or bariatric surgery. Because of this, the procedure is often combined with others such as breast lifts, facelifts and arm lifts to retain an attractive body proportion.

In a medial thigh lift (inner thigh lift), the surgical incision is made in the inner thigh along the line where the leg meets the groin. In a lateral thigh lift (outer thigh lift), the incision is made from the groin around the back of the body, so that the buttocks are lifted along with the thigh.
