Pearls and Pitfalls of Arthroscopic Iliopsoas Release

Pearls	Pitfalls
Shift standard AL portal anteriorly (2 cm anterior to femoral cortex) to provide access to iliopsoas “around the corner” of the anterior femoral cortex.	Standard anterior-posterior AL portal location will make visualization around the anterior femoral cortex challenging.
Distalize standard AL portal to be in line with the vastus ridge.	Standard proximal-distal AL portal location will lead to difficulty with iliopsoas sheath access given relatively distal location of desired access.
Immediately turn on fluid following AL portal trocar placement.	Dry scoping, as is standard for intra-articular hip access, will result in no potential space for triangulation and instrumentation when establishing MAP access.
Ensure circumferential iliopsoas tendon release.	Incomplete tendon release will result in bridging fibers that prohibit appropriate fractional lengthening of the iliopsoas.

AL, anterolateral; MAP, modified anterior portal.
