Preoperative knee laxity is not associated with subjective knee function or revision surgery after primary anterior cruciate ligament reconstruction: An analysis of 5425 patients

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine whether preoperative knee laxity, as measured by the KT‐1000 arthrometer, was associated with subjective knee function preoperatively and at 1, 2 and 5 years, or with revision anterior cruciate ligament (ACL) reconstruction (ACLR) within 5 years of the primary surgery.

How the Physical and Chemical Properties Affect the Heavy Metal Content in Surface Water in Different Types of Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Only ~3% of the global land surface is covered by peatlands, yet more than one‐third of global soil carbon is stored in these ecosystems and contaminant filtration can be provided. The extent to which peat humification (Fibric–Hemic–Sapric) is linked to dissolved heavy metals in peatland surface waters has remained poorly quantified at a ...

[18F]Fluorodeoxyglucose positron emission tomography ([18F]FDG PET) Characterizes Neurodegeneration Levels Across the α‐Synucleinopathy Continuum

Movement Disorders, EarlyView.
Abstract Background [18F]Fluorodeoxyglucose positron emission tomography ([18F]FDG PET) represents an endorsed neurodegeneration biomarker in neuronal α‐synucleinopathies. Idiopathic/isolated rapid eye movement (REM) sleep behavior disorder (iRBD) represents a prodromal stage of such disorders.

Nonparametric analysis of covariance in block designs

, 1993
Analysis of Covariance (ANOCOVA) has been considered as a more effective approach in data analysis than an ordinary Analysis of Variance (ANOVA) for two reasons: (1) increasing the power and precision of the tests through the reduction in error variance,

Metabolic and Volumetric Alterations in the Basal Ganglia and the Cerebellum in Dopa‐Responsive Dystonia in Symptomatic and Asymptomatic GCH1 Mutation Carriers

Movement Disorders, EarlyView.
ABSTRACT Background Dopa‐responsive dystonia is caused by pathogenic variants in the GCH1 gene. Although its clinical features and reduced penetrance are known, in vivo metabolic and structural alterations in symptomatic (sMC) and asymptomatic mutation carriers (aMC) remain poorly understood.
