Introduction

The external knee adduction moment during gait is a clinically useful measure for studying the initiation and progression of medial compartment knee osteoarthritis (OA) [1]. This quantity is the frontal plane moment of the ground reaction force vector about the knee center and possesses two peaks during stance phase—a first during early stance and a second during late stance. The largest peak is highly correlated with medial contact force [43], disease progression [26], disease severity [33], and pain [38]. For this reason, the peak knee adduction moment has become a quantitative target for clinical treatment of medial compartment knee OA.

Gait modification has recently received attention as a noninvasive alternative to high tibial osteotomy. This article reviews the current status and future direction of gait modification as a treatment for medial compartment knee OA, covering what exists, what is missing, and what is next.
