Hip surgery for femoroacetabular impingement syndrome (FAI)

Femoroacetabular impingement (FAI) syndrome was first reviewed by the HTA program in 2011.

  • In 2014, a review of FAI medical literature was conducted to determine if newly available published evidence could change the original coverage determination. The technology was not selected for re-review.
  • In 2018, a second update literature review was conducted. The technology was not selected for re-review.
  • In 2019, the HCA director selected FAI for re-review based on newly available published evidence that could change the original coverage determination.
  • A re-review of femoroacetabular impingement syndrome was completed in 2019.

    Status: Decision complete.

    Policy context:

    Femoroacetabular impingement (FAI) syndrome is a recently recognized diagnosis in primarily younger individuals where relatively minor abnormalities in the joint (orientation or morphology) are thought to cause friction/impingement and pain. It is theorized that FAI starts the breakdown of cartilage, leading to osteoarthritis (OA). There are two types of FAI: cam impingement (most common in young athletic males) and pincer impingement (most common in middle-aged women).

    Proponents believe that surgical correction of the impinging deformities will alleviate the symptoms and retard the progression of OA degeneration. However, significant questions remain about the safety, efficacy and effectiveness and cost effectiveness of hip surgery for FAI.

    Primary criteria ranking:

    • Safety = Medium
    • Efficacy = High
    • Cost = High
