Background:

  • Internal snapping hip syndrome is commonly due to iliopsoas tendon friction over the femoral head, especially in active individuals. When nonoperative management fails, surgical intervention is considered.

Methods:

  • IFL was performed arthroscopically in a supine position under traction. A complete transverse cut of the tendinous portion of the iliopsoas tendon was executed through standard portals.

Key Findings:

  • Arthroscopic IFL is effective in relieving symptomatic internal snapping and can be performed safely with other procedures such as labral repair or FAI correction.
  • Minimally invasive nature supports faster recovery and reduced soft-tissue disruption compared to open approaches.

What Does This Mean for Providers?

  • IFL is a reproducible arthroscopic technique for internal snapping hip unresponsive to conservative care.
  • Consider IFL particularly in cases with microinstability or concomitant pathology that necessitates intra-articular access.
  • Proper patient selection is essential to avoid overlengthening and subsequent hip flexor weakness.
