patient guide to femero-acetabular impingement and hip arthroscopy

The aim of this information sheet is to provide a provide Mr Parminder Singh’s patients a general guide to understanding what is femero-acetabular impingement, the assessment and investigation process and finally the hip arthroscopy surgical treatments. Every patient and every operation is unique and therefore this guide will not be able to answer all your questions.


This guide is not a substitute for obtaining medical advice from your surgeon. However, this guide may assist you to get a better understanding of what to expect and it may help you think of questions to ask Mr Parminder Singh.  If this patient information guide does not answer your questions, remember that Mr Parminder Singh will do his best to do so at your consultation. Mr Singh and his surgical team will practice in accordance with the ethical standards defined by the Australian Medical Council.

What is hip arthroscopy?

Hip arthroscopy is a minimally invasive surgical procedure that allows visualisation of the hip joint via a telescope type device known as an arthroscope via 1-2cm key holes incisions through the skin.


During the procedure the surgeon will be able to assess the condition of hip joint and diagnose and potentially treat hip injuries and disease.

Why would I need hip arthroscopy surgery?

Individuals  affected with symptomatic femero-acetabular impingement have been identified as at increased risk of developing arthritis in the hip joint.


Early intervention in the form of hip arthroscopy is an option of treatment that can help improve the symptoms, individuals often get with femero-acetabular impingement.  Long term studies (>10 years) are awaited to see if the arthritis process can be prevented or delayed.


Patients typically will suffer from the following symptoms:

  • Pain located in the groin
  • Associated pain particularly in the buttuck, side of the hip (lateral hip pain) , inside of thigh (adductors) and thigh region
  • Pain during activities walking, sitting to standing, running and twisting
  • Pain that has not improved with medicine and or physiotherapy for at least three months
  • Athletes, sportsmen, sportswomen and dancers typically describe pain on training and early fatigue.  These symptoms will improve with rest but often recur on resumption of exercise.

What conditions does hip arthroscopy surgery treat?

Mr Parminder Singh most commonly see’s two distinctive types of femoro-acetabular impingement (FAI) are recognised.

Pincer impingement

Occurs as a result of anterior over coverage (red triangle –figure B) of the acetabulum (socket) or acetabular retroversion causing abutment  against the femoral head neck junction during hip flexion  (figure c) causing damage to the hip joint particular the acetabular labrum


Where pincer type impingement predominates, abduction and external rotation movements may be more troublesome. 

A significant proportion of female patients with impingement will report exacerbation of their symptoms during sexual intercourse.  In cases of pincer type impingement ranges of movement may appear normal but with pain towards the extremes of movement.

Cam impingement

Occurs when a non-spherical femoral head (red semi-circle see figure B) abuts against the anterior acetabulum (C), usually with the hip in flexion causing damage to the hip joint, particularly the cartilage and labrum.  In patients where cam impingement predominates, symptoms are often precipitated by prolonged upright sitting and internal rotation movement in flexion.


An examination of the hip joint will often reveal asymmetric ranges of movement and evidence of irritability.  Cases of  large Cam impingement typically show reduced internal rotation of the hip in flexion.  A portion of individual will have the condition affecting both hips.

In practice it is common to see a mixed Cam and Pincer pathology, occurring along the anterior femoral neck and the anterior–superior acetabular rim.

Other conditions Hip Arthroscopy treats:


  • Acetabular labral tears
  • Femero-acetabular impingement (FAI)
  • Cartilage Repair

  • Ligamentum teres tears

  • Synovitis
