Flat foot could boost knee replacement risk

Older people who have flat foot are more likely to suffer chronic knee pain or osteoarthritis of the knee.

According to new research published in the journal Arthritis Care & Research, having flat feet increased the chances that a person over the age of 50 would suffer knee pain on a daily basis by almost a third.

What's more, researchers, from the Boston University School of Medicine and the Massachusetts General Hospital Institute of Health Professions, found that flat-footed patients were 43 per cent more likely to show cartilage damage on the inside of their knees - a problem that often leads to knee surgery.

Principal author K Douglas Gross said the research does not prove that flat feet caused cartilage damage, but it does highlight the strong link between the two.

"When your feet flatten, it can change your posture or the way you move," he noted.

The assistant professor added that if further research supported the link between flat feet and knee osteoarthritis, then GPs and orthopaedic surgeons may start recommending the use of tailored insoles to combat the wear and tear caused by altered posture.

Recently, Lorraine Jones, a podiatrist from the Society of Chiropodists and Podiatrists, warned women over 50 not to wear high heels on a daily basis as they put increased pressure on the back and knees.
