Portal enlargement in hip arthroscopy preserving the iliofemoral ligament: a novel access technique protecting soft tissue restraints.

Capsulotomy in different modalities has been used to provide adequate exposure to access both the central and peripheral compartment in hip arthroscopy. Even though the hip joint has inherent bony stability, soft tissue restraints may be important in patients with ligaments hyperlaxity or in some cases with diminished bony stability. Biomechanical studies and clinical outcomes have shown the relevant role of the capsule in hip stability, mainly the role of the iliofemoral ligament.

Arthroscopic Decompression of a Type III Subspine Impingement.

Extra-articular hip impingement refers to a variety of hip disorders causing pain and limited function in young, non-arthritic patients. Recently, there has been an increased focus on analyzing the degree of anterior inferior iliac spine (AIIS) dysmorphism and its correlation with subspine impingement (SSI), defined as abutment between a prominent distal aspect of the AIIS and the anterior aspect of the femoral head-neck junction. Arthroscopic decompression of the AIIS is recognized as an effective treatment for SSI.
