Double‐Bundle Artificial Medial Patellofemoral Ligament Reconstruction Using a Femoral Suture‐Sliding Anchor and Patellar Staged Tension Adjustment

open access: yesArthroscopy Techniques, EarlyView.
Abstract Double‐bundle medial patellofemoral ligament reconstruction with artificial ligaments is a minimally invasive surgical option for recurrent patellar dislocation. However, it carries a risk of over‐tensioning, which may lead to restricted patellar mobility and anterior knee pain.

Defect engineering for highly efficient and stable perovskite top cells for Si tandems

open access: yesBulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...
