Femoral osteotomy is a surgical procedure that is performed to correct specific deformities of the femur – the long bone in the upper leg – and the hip joint. Orthopedic surgeons perform the operation, which involves cutting the bone, in order to realign it and restore a more normal anatomy, thereby addressing or preventing problems related to the deformity. These problems may include articular cartilage damage in the hip joint, tears to the labrum (the crescent-shaped cartilage structure that runs along the rim of the hip socket) and various forms of hip impingement – abnormal contact between the two bones that meet in the hip joint.
