Arthroscopic Repair of the Anterior Root of the Lateral Meniscus Using Knotless All‐Suture Anchors

Arthroscopy Techniques, EarlyView.
Abstract Anterior root tears of the lateral meniscus are uncommon but can significantly disrupt knee biomechanics by increasing contact pressures and accelerating cartilage degeneration if left untreated. This article describes an arthroscopic technique for repair of the anterior root of the lateral meniscus using all‐suture anchors.

Arthroscopic Reinsertion of an Anterior Cruciate Ligament Tibial Spine Fracture Avulsion With Double‐Strand Lacing of Anterior and Posterior Bundles

Arthroscopy Techniques, EarlyView.
Abstract Avulsion fractures of the tibial spines have the same mechanism as anterior cruciate ligament ruptures but occur more often in subjects with an immature skeleton or in osteoporotic subjects. Displacement of more than 2 mm generally requires fixation.

Modified Transtibial Pullout Repair for Medial Meniscus Posterior Root Tear Using a Barbed Suture: A Technical Note

Arthroscopy Techniques, EarlyView.
Abstract This technical note describes a modified transtibial pullout repair for medial meniscus posterior root tear incorporating a barbed suture to improve fixation strength and load distribution. The technique combines 2 simple sutures placed near the torn root with a circumferential barbed suture passed through the posteromedial meniscocapsular ...

Short-Circuit Calculation and Overcurrent Relay Protection in AC Microgrids: A Review

Energies
AC microgrids with high penetration of inverter-based distributed energy resources (IBDERs) introduce major protection challenges due to reduced fault current levels, bidirectional power flows, and control-dependent fault behavior. Under these conditions,

Emotional nourishment begets academic coping during the primary to secondary school transition

British Educational Research Journal, EarlyView.
Abstract The transition from primary to secondary school is widely viewed as the most demanding in a child's educational journey. Despite a wealth of research on this transition, little is known about the children's ‘lived experience’ of it across different contexts.
