Arthroscopic Remplissage With Knotless All‐Suture Anchors and Concomitant Bankart Repair: Technical Considerations

open access: yesArthroscopy Techniques, EarlyView.
Abstract Anterior shoulder instability is common in active patients. Traumatic dislocations may produce Bankart and Hill‐Sachs lesions that increase recurrence risk. In high‐demand individuals, isolated Bankart repair may be insufficient for off‐track or near‐track Hill‐Sachs lesions.

Beyond antimicrobials: Ecological nano‐strategies for rebalancing dysbiotic oral microbial homeostasis

open access: yesBMEMat, EarlyView.
Oral microbial homeostasis, a dynamic host‐microbe balance, is vital in infectious diseases. Conventional antibiotics often disrupt this homeostasis, spurring interest in nanomaterials for oral microbial homeostasis rebalancing. This review outlines nanomaterial strategies across three ecological levels (population/community, ecosystem, and cross ...
