Editorial Commentary: Small Labral Size on Magnetic Resonance Imaging Is an Indication for Labral Reconstruction in the Setting of Revision Hip Arthroscopy.

Revision hip arthroscopy is an increasingly common procedure as rates of primary hip arthroscopy rise. Etiologies for symptom recurrence may include residual femoroacetabular impingement, cam over-resection, labral pathology, chondral wear, adhesions, and instability. This has spawned sophisticated surgical techniques in hip arthroscopy including labral reconstruction.

Effectively utilizing publicly available databases for cancer target evaluation.

The majority of compounds designed against cancer drug targets do not progress to become approved drugs, mainly due to lack of efficacy and/or unmanageable toxicity. Robust target evaluation is therefore required before progressing through the drug discovery process to reduce the high attrition rate. There are a wealth of publicly available databases that can be mined to generate data as part of a target evaluation.

Posterolateral Acetabuloplasty and Distal Femoral Neckplasty, Labral Repair, and Capsular Plication for Hip Reverse Contre-Coupe Lesion.

This article describes the arthroscopic approach and management of a "reverse contre-coup" injury to the hip labrum. The injury occurs in the setting of posterolateral acetabular rim over-coverage impinging on the distal femoral neck in extension causing the femoral head to lever out anteriorly against the labrum. Ligamentous laxity and associated loss of anterior capsular restraint allow increased femoral head translation, adding further insult to the anterior labrum.

Multimerin-2 is a ligand for group 14 family C-type lectins CLEC14A, CD93 and CD248 spanning the endothelial pericyte interface.

The C-type lectin domain containing group 14 family members CLEC14A and CD93 are proteins expressed by endothelium and are implicated in tumour angiogenesis. CD248 (alternatively known as endosialin or tumour endothelial marker-1) is also a member of this family and is expressed by tumour-associated fibroblasts and pericytes. Multimerin-2 (MMRN2) is a unique endothelial specific extracellular matrix protein that has been implicated in angiogenesis and tumour progression.

Minimum 2-Year Outcomes of Hip Arthroscopic Surgery in Patients With Acetabular Overcoverage and Profunda Acetabulae Compared With Matched Controls With Normal Acetabular Coverage.

Background: Advancements in instrumentation and techniques have extended the scope of hip arthroscopic surgery to treat complex osseous deformities that were previously best addressed with an open approach. Global pincer-type femoroacetabular impingement is an example of an abnormality requiring osseous correction with a technically challenging access point.

Purpose: To report on the patterns of clinical presentation and intra-articular derangements, radiological associations, and minimum 2-year outcomes after hip arthroscopic surgery in patients with a lateral center edge angle (LCEA) >40° and profunda acetabulae in comparison with matched controls with normal acetabular coverage.

Outcomes of gluteus maximus and tensor fascia lata transfer for primary deficiency of the abductors of the hip.

Purpose: This study aims to present 3 patients' results after undergoing gluteus maximus and tensor fascia lata (TFL) transfer for chronic abductor tears unable to be repaired primarily.

Methods: 3 patients were identified intraoperatively as having an abductor tear unable to be repaired primarily. The anterior 1/3 of the gluteus maximus and the posterior 1/3 of the TFL were mobilised and transferred to the greater trochanter in order to reproduce the normal force vector of the gluteus medius and minimus.

Acetabular Chondral Lesions in Hip Arthroscopy: Relationships Between Grade, Topography, and Demographics.

Background: Hip pain remains a challenge given the multiple factors that can cause damage to the articular cartilage, such as traumatic injury, metabolic damage, and morphologic variations such as femoroacetabular impingement (FAI) and that can contribute to progression of osteoarthritis. However, a direct relationship between patient characteristics, the extent of acetabular chondral damage, and topologic characteristics of chondral lesions has not been established.

Purpose: To compare the grade of acetabular chondral damage, measured in terms of acetabular labrum articular disruption (ALAD) classification, to the size and position of the chondral lesions, matching patients' demographic factors such as age and body mass index (BMI).
