Both arthroscopic and open operative treatment of femoroacetabular impingement (FAI) can reproducibly relieve hip pain with correction of the underlying osseous deformity and treatment of the associated labral pathology, particularly in patients without substantial articular cartilage injury at the time of surgery.
Between 75% and 90% of athletes undergoing FAI surgery return to sports at their pre-injury level of function. There is no peer-reviewed evidence to date reporting on the efficacy of nonoperative treatment and return to play with FAI.
Successful operative treatment of impingement requires appropriate and complete correction of the mechanical injury that led to the symptomatic labral pathology.
Early intervention prior to the onset of irreversible chondral damage is critical to the long-term success of FAI surgery.
Complex deformities involving combinations of static and dynamic mechanical factors often coexist, so careful preoperative evaluation of the underlying structural anatomy is critical to successful treatment planning.
