Arthroscopic Pincer Resection Utilizing an Outside-In Approach for Intra-articular Access.

In the standard approach to hip arthroscopy, access to the joint is achieved using fluoroscopic guidance to enter the central compartment of the hip using the Seldinger technique, penetrating the capsule with a needle and subsequently cannulating and obtaining direct visualization of the joint. In such a way, arthroscopists then proceed with accessory portal creation and capsulotomy, as desired, under direct intra-articular visualization. In cases with severe pincer morphology or coxa profunda, it may not be possible to safely access the central compartment under fluoroscopic guidance due to significant lateral overcoverage of the femoral head. We present an outside-in arthroscopic approach for accessing the hip joint in such patients, allowing for safe visualization, osseous pincer resection, and improved central compartment access while minimizing the risk to cartilage and labral tissue.
