摘要Introduction: Foot posture have been proposed to be associated with knee osteoarthritis, as altered lower limb alignment could lead to uneven distribution of force. Previous studies have documented attempts to include foot posture correction in the onservative management plan for knee osteoarthritis. However, results were controversial. In this study, the association between foot posture and knee osteoarthritis was investigated.

Methods: Forty-six elderly participants with mean age of 69.2 years were invited from a health-promotion programme (MusFit cohort) for assessment. Foot posture index (FPI) was calculated for both feet, which a cut-off of >5 either foot was adapted for classification of foot pronation. Kellgren and Lawrence (KL) grading was used to assess radiographic severity of degeneration, while Knee injury and Osteoarthritis Outcome Score (KOOS) was performed to assess for function. Fisher exact test was performed to investigate the association between presence of foot pronation with radiological severity of knee degeneration and function.

Results: Thirty out of 46 participants presented with foot pronation. Foot pronation was not associated with high KL grade of 3 or 4 (p=0.789). There was no significance difference between functional score of pain (p=0.916), symptoms (p=0.895), ADL (p=0.531), sports (p=0.292), and QOL (p=0.124) between participants with and without foot pronation.

Discussion and Conclusion: Foot pronation was commonly observed. However, existence of foot pronation was not associated with radiological severity, nor functional condition of knee osteoarthritis. This study supports that correction of foot pronation may not be an effective method in the conservative management strategy of knee osteoarthritis.
