Relationship between x ray findings of knee osteoarthritis and foot posture

Research Abstract

Foot posture has been postulated as a risk factor for the development and progression of knee osteoarthritis (OA); however the link between the radiographic findings of the knee and foot posture is not clear. The aim of this study was to investigate the relationship between the radiographic severity of knee OA and foot posture in subjects with medial knee OA. Thirty patients with medial knee OA were undergone to radiographic examination to their knees to classify the severity of OA according to Kellgren-Lawrence grades (K/L I-IV); then, they were undergone to foot examination using the foot posture index (FPI) and arch index (AI). Spearman correlation coefficient was used to investigate the relation between KL grades and both of FPI and AI.KL grades were not correlated to FPI or AI. Subjects with medial knee OA showed no correlation between severity of their disease and foot posture. Future longitudinal study may be helpful to investigate the effect of severity on foot posture.
