“…[5,6] Some propose that the iliocapsularis helps to prevent synovial impingement on the anterior aspect of the joint capsule. [2] This accords it a similar function to the articularis genus of the knee joint. In principle, the iliocapsularis would prevent impingement during hip flexion by creating tension in the joint capsule.…”

“…During complete hip arthroplasty, the lateral aspect of the iliocapsularis is commonly used as the location for capsulotomy. [1,2] Using the intermuscular space between the inserting fibers of the gluteus minimus and the iliocapsularis as landmarks ensures a precise T-capsular incision while avoiding injury to these muscles and tendons and to the vascular supply to the hip.

“…By moving the transducer caudally, the insertion onto the lesser trochanter is visualized. [2] The iliocapsularis is best visualized with MRI using axial slices through the femoral head. It lies just superficially and laterally to the joint capsule.…”

“…It originates from the anterior inferior iliac spine and the anteromedial hip joint capsule and inserts on to the lesser trochanter. [1][2][3][4] Although the iliocapsularis is apparently constant in humans, the literature fails to describe it in detail. Interestingly and comparatively, it has been found in primates, rats, reptiles, and birds.…”

The iliocapsularis muscle covers the anterior aspect of the hip joint capsule. Although its anatomy has been described through cadaveric and radiologic studies, its true function is unknown. The iliocapsularis could be involved in preventing anterior synovial impingement, a possibility supported by electromyography studies. Moreover, hypertrophy of the iliocapsularis caused by hip dysplasia supports the proposal that it stabilizes the anterior aspect of the joint capsule. This review discusses the clinical relevance of the iliocapsularis.

Anterior hip joint musculature is classically characterized to include iliacus, psoas major, rectus femoris, and sartorius muscles. A lesser‐known muscle, iliocapsularis muscle (ICm), has made infrequent appearances in the literature for the last ~70 years, but potentially has important functional and clinical value. The purpose of this study is to review the historical prevalence of the ICm in peer‐reviewed literature (PRL), further explore the prevalence of the muscle in current anatomical textbooks (ATBs), characterize the muscle with a new series of dissections, assess the muscle's perceived importance to clinicians and educators, and comment on the possible functional significance of the muscle. The ICm was mentioned in 28 peer‐reviewed articles and the muscle was present in 518 of 521 (99%) dissected hips in 13 publications which assessed prevalence. In an audit of 30 recently published ATBs, three texts mentioned the ICm. In 28 anterior hip dissections performed in the current study, the muscle was present in all hips. Anatomy educators were surveyed to determine if the ICm was presently taught in their curricula, and clinicians of various specialties were surveyed regarding their perceptions of the ICm and its clinical relevance. The ICm inclusivity within anatomical curricula from educators reported 8.5%, while 4% of clinicians reported trainees should have an educational background of the ICm. This study confirms that while the ICm is present within PRL, and is ubiquitous amongst human‐donor dissection, the ICm is not mentioned in most ATBs and is absent in the vast majority of anatomical curricula. Lack of inclusion in curricula may lead to a perceived insignificance to currently practicing clinicians despite the potential functional importance at the hip. This discordance suggests that the ICm should be included in ATBs and anatomical curricula so that future clinicians can consider the ICm when evaluating and treating patients.
