The external knee adduction moment during gait is a clinically useful measure for studying the initiation and progression of medial compartment knee osteoarthritis (OA). 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, disease progression, disease severity, and pain. 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. The interested reader is also referred to recent review articles on related topics.
