Femoral Acetabular Impingement

What is femoral acetabular impingement (FAI)?

Femoral acetabular impingement (FAI) is a condition in which abnormal contact occurs between the femoral head/neck and the hip socket (acetabulum) during movement, causing friction that can damage the joint over time. This is usually due to extra bone forming on the femoral head (cam type), the socket (pincer type), or a combination of both.

Symptoms

Common symptoms of femoral acetabular impingement (FAI) include:

  • Groin pain

  • Stiffness, particularly with hip flexion

  • Reduced range of motion

  • Clicking or catching sensations

  • Pain with prolonged sitting or activity

Causes and risk factors

Femoral acetabular impingement (FAI) can develop for a number of reasons, including:

  • Developmental variations in bone shape

  • Repetitive hip movement, particularly in certain sports

  • Genetic factors

Treatment options for femoral acetabular impingement (FAI)

Treatment for FAI depends on the severity of symptoms and the degree of any associated joint damage, such as a labral tear.

Non-surgical treatment

Non-surgical treatment is often tried first, and may include:

  • Physiotherapy

  • Activity modification

  • Anti-inflammatory medication

  • Joint injections

Surgical treatment

When symptoms persist despite non-surgical treatment, surgical treatment may be considered:

  • Hip Arthroscopy — used to reshape the affected bone and address any associated damage, such as a labral tear.

Femoral Acetabular Frequently Asked Questions

Does FAI always require surgery?

No, many patients manage their symptoms successfully with non-surgical treatment. Surgery is generally considered when symptoms persist.

Is FAI related to labral tears?

Yes, FAI is a common cause of labral tears, as the abnormal contact between bones can damage the labrum over time.
