Thin flap sulcus-deepening trochleoplasty in patellar instability yields good functional outcomes without progressive cartilage deterioration in the short-term follow-up-A retrospective single-surgeon cohort study.

Purpose: Sulcus-deepening trochleoplasty (TP) effectively treats patellofemoral (PF) instability (PFI) caused by high-grade trochlear dysplasia (TD), but current evidence is based on small case series. We hypothesised, that TP would result in significant functional improvements and a low re-dislocation rate but would not accelerate the progression of PF cartilage deterioration.

Methods: We retrospectively reviewed all TP cases performed by a single surgeon between 2015 and 2021.

Nothing to hide: How governments justify the adoption of ag-gag laws.

Mainstream practices for producing meat, eggs, and dairy raise numerous concerns regarding public health, animal welfare, and environmental integrity. However, governments worldwide have expanded anti-whistleblower legislation that constrains informed public debate. Since 2019, several Canadian provinces have adopted so-called "ag-gag" laws designed to prevent hidden-camera investigations on farms and meat processing facilities.

"You're Just Stuck in a Hole, Really": Mechanisms of Structural Racism Through Migrant Agricultural Worker Housing in Canada.

Worldwide, migrant agricultural workers face poor housing conditions and related health challenges. A growing body of research has documented the substandard housing often occupied by this largely racialized population. Yet limited health research has examined mechanisms of structural racism that determine this group's poor housing and health.

Specific fibre areas in the femoral footprint of the posterior cruciate ligament act as a major contributor in resisting posterior tibial displacement: A biomechanical robotic investigation.

Purpose: Similar to the anterior cruciate ligament, the femoral footprint of the posterior cruciate ligament (PCL) is composed of different fibre areas, possibly having distinct biomechanical functions. The aim of this study was to determine the role of different fibre areas of the femoral footprint of the PCL in restraining posterior tibial translation (PTT).

Methods: A sequential cutting study was performed on eight fresh-frozen human knee specimens, utilizing a six-degrees-of-freedom robotic test setup.
