“…It is a triangular structure and in cross-section is widest in the anterior half and thickest in its superior half [19,22]. The blood supply to the labrum derives from the joint capsule [16,19]. From the capsule, blood vessels enter the peripheral part of the labrum and travel circumferentially around the structure at its attachment to bone.…”

“…Given that meniscal repair is confined to the vascular zone (19), recent investigation has evaluated the vascularity of the hip labrum. Kelly et al evaluated the vascular supply of the hip labrum and noted that the capsule provided the major vascular contribution to the labrum, but that the labrum overall was relatively avascular (20). Labral tears showed a trend of increased vascularity; thus, agents that could potentially augment regional vascularity may prove helpful in subsequent repair of the labrum, rather than labral resection.…”

The relatively thin cartilage of the hip joint, as well as its complex geometry, poses challenges for standardized, reproducible assessment of cartilage and the acetabular labrum. With appropriate pulse sequence parameters, however, accurate, reproducible assessment of cartilage and the labrum is feasible. More detailed evaluation of cartilage biochemistry may be obtained with techniques aimed at noninvasively evaluating the integrity of collagen and/or proteoglycan components in the articular cartilage. One of the benefits of noncontrast techniques lie in the ability to visualize the native synovium, and thereby detect the presence of synovial proliferative disorders, the clinical symptoms of which may mimic a labral tear or traumatic cartilage injury. Standard cartilage evaluation allows for the detection of surface delamination and osteoarthritis in the setting of femoroacetabular impingement, as well as subtle areas of subchondral collapse and secondary delamination of cartilage in the setting of osteonecrosis. This preserves the use of hip arthroscopy as a therapeutic rather than a diagnostic tool.

“…Cadaveric studies have confirmed these findings and suggest that a potential cause for limited healing at the chondrolabral junction is the result of vascular compromise. The articular side of the labrum has been shown to be relatively avascular compared with the capsular side, 12 and because traditional labral repair and osteoplasty techniques likely transect labral blood vessels, 13 the chondrolabral junction is at particular risk. The main advantage of the technique we present is that it mitigates the limited healing potential of the chondrolabral junction by preserving the chondrolabral junction while performing acetabuloplasty.…”

Traditional techniques for acetabular osteoplasty in femoral acetabular impingement have required surgical detachment of the labrum at the chondrolabral junction. Such approaches compromise labral blood flow and contribute to a limited ability for healing at the chondrolabral junction. In this technical note and accompanying video, we present a technique for preservation of the chondrolabral junction during labral repair and acetabular osteoplasty. We elevate the chondrolabral complex subperiosteally off the acetabular rim, and the acetabular shelf is then contoured under fluoroscopic guidance. The labrum is then repaired and reconstituted to a new anatomic footprint. We find this technique to be advantageous because it preserves the blood flow to the labrum, thereby maximizing healing potential. Outcome studies are warranted to further elucidate the functional and outcome benefits of this surgical technique.
