Biomechanical mechanisms behind the reduction of knee adduction moment in medial knee thrust gait.

ABSTRACT: Medial knee osteoarthritis (OA) is the most common OA subtype, and its progression has been strongly linked to increased knee adduction moment (KAM). Among various gait modification strategies, medial knee-thrust gait has emerged to be promising to attenuate KAM. This study aimed to clarify the biomechanical mechanism through which knee-thrust gait reduces KAM. Fourteen healthy young adults were recruited as a first step to understanding the mechanism. KAM was reduced by 21% in the first peak and 36% in the second peak during the knee-thrust gait compared to the normal gait. Stepwise multiple regression indicated that the moment arm (MA) was the primary contributor to both KAM peaks (adj. R² = 0.9, respectively). Furthermore, the reduction in MA was caused by the lateral deviati
