Femoral-Acetabular Impingement (FAI)

Femoral-Acetabular Impingement (FAI) What is FAI? The most common cause of hip Hip Arthroscopy labral tearproblems in the athlete is called femoral-acetabular impingement or FAI.  FAI is caused by a mismatch in the ball and socket so that when the hip is moved the ball runs into the socket and the structures in between can be pinched.  The mismatch can be the socket being too deep, the ball being to wide or a combination of both.  The contact between the ball and socket leads to tearing of the labrum (seal around the outside of the socket) and damage to the cartilage in the ball and socket joint.  Once the labrum is torn, it can lead to micro-instability of the joint and pain.  The instability is bad for the cartilage and eventually leads to the cartilage wearing out and arthritis.  Dr. Petre is one of, if not the only, fellowship trained hip surgeons in the mid-atlantic region who performs repairs or reconstructs the acetabular labrum arthroscopically.

Non Surgical Treatment

The best place to start with hip pain is non-surgical treatment.  Though rest, anti-inflammatories, activity modification and selective strengthening of the muscles around the hip, pelvis and spine, hip pain can often be alleviated completely.  Occasionally, injections of medications or biologic augmentation need to be added in order to help the healing process.Slide2

Surgical Treatment

If non-surgical treatment fails to provide pain relief and return the athlete to sport then surgery may be necessary.  Surgery for FAI has two main goals, the first is to remove the extra bone on the ball or the socket that created the problem in the first place, the second is to repair the damaged structures.  Dr. Petre believes in doing this all arthoscopically.  Surgery is just the first part of the treatment, Dr. Petre will help guide you through a 3 to 6 month rehabilitation process before you are fully back to sports.  Dr. Petre believes in early rehab with motion right away, patients will need to do rehab every day on their own in addition to 2-3 times a week with a therapists for a minimum of 3 months.
