Investigating OA: Studies revisit underlying variables

By Jordana Bieze Foster Knee osteoarthritis researchers are taking a closer look at the factors that influence knee adduction moment (KAM) and also considering the contributions of sagittal plane variables, as illustrated by studies presented in September at the American Society of Biomechanics (ASB) annual meeting in Omaha, NE. The knee-ground reaction force (GRF) lever arm is a stronger predictor of KAM after arthroscopic partial meniscectomy (APM) than frontal plane GRF magnitude and therefore might be a desirable focus for interventions to prevent or delay the development of knee osteoarthritis in these patients, according to research from the University of Melbourne in Australia. Investigators performed a secondary analysis of gait data from an earlier study in which 65 individuals with isolated medial APM demonstrated a statistically significant 9% increase in KAM two years after surgery.
