Developmental morphology of claspers and clasper‐glands during maturation in Potamotrygon wallacei (Chondrichthyes: Potamotrygoninae)

open access: yesThe Anatomical Record, EarlyView.
Abstract The claspers are the copulatory organs in male elasmobranchs, responsible for directing the semen into the female cloaca (C). However, the microscopic morphology of the claspers remains poorly understood. This study describes the morphology of the claspers and clasper glands (CGs) of cururu stingray (Potamotrygon wallacei) at different ...

Integrated microanatomy and microstructure of the maxillary tooth plate reveal a reinforced feeding system and tougher diet in Late Triassic Hyperodapedontinae (Rhynchosauria, Archosauromorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Hyperodapedontine rhynchosaurs possessed a unique oral apparatus, long interpreted as an adaptation for processing abrasive and resistant plant material. However, the microanatomical and histological evidence supporting this interpretation remains poorly documented.

Tracheal chambers as a key innovation for high‐frequency emission in bat echolocation

open access: yesThe Anatomical Record, EarlyView.
Abstract Key innovations are pivotal for biodiversity and facilitating evolutionary success, enabling organisms' adaptation to various ecological niches through the diversification of phenotypic traits. In mammals, notable adaptations include evolving hypsodonty for grazing on grasses and, for bats, evolving echolocation and wing acquisition.

Continuous Sewing Machine‐Like Suture Provides Higher Failure and Yield Load Compared to Traditional Techniques for Meniscal Root Repair in a Biomechanical Porcine Model

open access: yesArthroscopy, EarlyView.
Purpose To evaluate the biomechanical performance of the sewing machine‐like suture (SMS) technique against three established techniques (two cinch‐loop (TCL), modified Mason‐Allen (MMA), and double Mason‐Allen (DMA)) for transtibial pull‐out repair of posterior medial meniscal root tear (PMMRT) in a porcine model.

Computed Tomography‐Based Morphometric Analysis Reveals Intercondylar Notch Stenosis and Osteophytes Are Associated With Anterior Cruciate Ligament Injury

open access: yesArthroscopy, EarlyView.
Purpose To quantitatively assess intercondylar notch morphometrics using 3‐dimensional computed tomography reconstruction, evaluate their association with anterior cruciate ligament (ACL) injury in Asian populations, and investigate the prevalence of osteophytes in patients with ACL injury.

Superior Capsular Reconstruction Technique for Massive Rotator Cuff Tear With Arthroscopic Transfer and Augmentation of Long Head of Biceps Brachii Tendon—The Biobridge Technique

open access: yesArthroscopy Techniques, EarlyView.
Abstract Massive irreparable rotator cuff tears remain a major surgical challenge, often leading to pain, functional loss, and superior humeral migration. Superior capsular reconstruction has emerged as a technique to restore superior stability.

Rimplasty: An Arthroscopic Technique for Patients With Isolated Patellar Chondromalacia Based on Autologous Matrix‐induced Chondrogenesis+ and Limited Trochleoplasty

open access: yesArthroscopy Techniques, EarlyView.
Abstract Anterior knee pain is a common problem that can be difficult to treat. One potential cause of these symptoms is supratrochlear rim, which has been linked to isolated patellar chondromalacia in patients with patella alta and without any history of patellar dislocation or subluxation.

Extracellular Matrix With Bone Marrow Aspirate Concentrate for Osteochondritis Dissecans of the Capitellum in Adolescents

open access: yesArthroscopy Techniques, EarlyView.
Abstract Capitellar osteochondritis dissecans is most frequently encountered in overhead and tumbling adolescent athletes. Traditional management with abrasion chondroplasty or microfracture results in fibrocartilage formation and variable return to sport rates, whereas osteochondral autograft transfer system or osteochondral allograft transplantation ...

Two‐Handed Knot Tying Technique for Arthroscopic Surgeries

open access: yesArthroscopy Techniques, EarlyView.
Abstract Knot tying is a widely used and essential technique in arthroscopic tissue repair and fixation. Although it shows perceived simplicity, its technical complexity exceeds that of open surgery due to the challenges of suture fixation within confined intra‐articular spaces and demanding execution requirements.

Patellar Tendon Revision Reconstruction Using Transosseous Patella All‐Suture Anchors, Semitendinosus Autograft, and Achilles Allograft

open access: yesArthroscopy Techniques, EarlyView.
Abstract Patellar tendon rupture is an uncommon but highly treatable injury, with excellent repair outcomes and low reoperation rates. Chronic patellar tendon ruptures or repair failures pose a clinical challenge, but the success rates of reconstruction with extensor mechanism allograft or autograft are reported to be high in the literature. Still, the
