TL;DR: Knee pain while ascending stairs and while walking on a flat surface or bending to the floor or standing up was a probable limiting factor for physical activity in early and severe knee OA, respectively.

TL;DR: It is indicated that depression may be associated with increased knee pain intensity during daily living in a non-task-specific manner and is associated with functional limitation in patients with knee OA, even after controlling for covariates, including bilateral knee pain and ambulatory physical activity.

TL;DR: Although increased ambulatory PA had a positive relationship with better physical function, walking <2500 steps/d may be a simple indicator for a decrease in physical function in patients with knee OA among standard PA categories.

TL;DR: The results of the exploratory analysis suggested that patients with coexisting PFOA might have heterogeneous clinical outcomes, and presence of mixed P FOA might be an indicator of severe clinical knee OA.

TL;DR: Varus thrust was associated with PFOA in a compartment-nonspecific manner in patients with medial knee OA, indicating that varus thrust may represent a clinical disease feature of more advanced and multicompartmental disease.
