The acetabular labrum plays a key role in proper biomechanical hip function through creation or maintenance of a suction seal between the femoral head and acetabulum. The suction seal effect has been shown to provide stability within the hip, improve biomechanics, and decrease the chance for long-term development of osteoarthritis by optimizing function and force distribution within the hip. Femoral acetabular impingement syndrome damages the labrum and chondrolabral junction, thus negatively impacting the ability of the labrum to maintain native suction seal. Our technique describes the use of a postless hip arthroscopy table and the on-off traction technique throughout the labral repair, ensuring precise reduction of the labrum and restoration of the suction seal sequentially as anchors are placed.

As surgeons, we strive to recognize and correct any mistakes that may occur before completing an operation, and importantly, do our best to avoid irreversible mistakes. Over-resection of the femoral cam lesion in patients having hip arthroscopy for femoroacetabular impingement syndrome has been considered irreversible. While cam under-resection is a technical complication of femoroacetabular impingement surgery to be avoided, avoiding this at the expense of over-resection of the proximal femur is of great concern.

The combination of hip arthroscopy and periacetabular osteotomy (PAO) has been proven safe and effective for addressing symptoms in patients with developmental dysplasia of the hip. As not every patient with dysplasia will require a hip arthroscopy to obtain desired clinical improvement in the setting of PAO, a challenge is identifying which patients require adjacent procedures (either via arthroscopic or open) to fully treat their hip pathology. Even though labral repair is the most reported arthroscopic procedure in cases of hip dysplasia, I would suggest that labral treatment is the least likely helpful component of hip arthroscopy in these cases.

Many aquatic organisms utilize suction-based organs to adhere to diverse substrates in unpredictable environments. For multiple fish species, these adhesive discs include a softer disc margin consisting of surface structures called papillae, which stabilize and seal on variable substrates. The size, arrangement, and density of these papillae are quite diverse among different species, generating complex disc patterns produced by these structures.

Purpose: To evaluate the effect of depth and location of femoral osteoplasty or the use of remplissage on the suction seal in a sheep hip model.
Methods: The hips of 32 twelve-month-old sheep were used as a cam-type femoroacetabular impingement model. The subjects were divided into 4 groups, each undergoing a distinct surgical procedure: group I underwent a 5% cam resection at the head/neck junction, group II had a 10% cam resection at the head/neck junction, group III received a 5% cam resection from 5 mm proximal to the head/neck junction, and group IV underwent remplissage to replace the loss of the suction seal with an extensor tendon graft in the defected area after a 10% cam resection at the head-neck junction.

Background: Whereas uncomplicated labral tears with preserved fibers can be effectively treated with use of labral repair techniques, complex tears and hypoplastic labra require labral reconstruction. Standard reconstruction techniques feature grafted tissue that is added to existing, deficient tissue or that is utilized to replace a hypoplastic labrum entirely. However, such approaches utilizing allografts or remote autografts are limited because they often necessitate extensive debridement of the existing labrum to prepare a site for graft implantation, an approach that can damage and devascularize the chondrolabral junction.
