Structure
The triangular pubofemoral ligament lies anterior and inferior to the articular capsule of the hip joint. It base originates from the obturator crest, iliopubic eminence, and superior ramus of the pubic bone. It courses laterally and inferiorly to coalesce with the fibrous layer of the articular capsule of the hip joint and the descending part of the iliofemoral ligament (Moore, Dalley and Agur, 2013; Standring, 2016).
Function
Collectively the ligaments of the hip joint contribute significantly to the stability, excursion, and capacity of the joint. Specifically, the pubofemoral ligament tightens during extension and abduction of the hip joint and prevents hyperabduction (Moore, Dalley and Agur, 2013).

Joint Ligament
Entheseal structures are widely located throughout the body and are represented by the interface between bone and several tissues including tendon, joint capsules and ligaments.
