But knee ache from osteoarthritis needn’t go hand in hand with ageing – or working. Analysis has shed new gentle on its causes, and we will neglect blaming all of it on “put on and tear”. The kilo creep is a significant offender, not solely as a result of it burdens the knee joint with further weight but additionally as a result of an excessive amount of fats across the waist produces inflammatory chemical compounds that harm knee cartilage, explains Professor Flavia Cicuttini, head of Rheumatology at Melbourne’s Alfred Hospital and of Monash College’s Musculoskeletal Unit.

Which is the place leisure runners could also be doing their knees a favour.
“Individuals fear that working will put on out the knee joint however it will possibly enhance joint well being by offering vitamin to the articulate cartilage of the knee by retaining the joint shifting,” says Professor Ilana Ackerman, Deputy Director of the Monash-Cabrini Division of Musculoskeletal Well being and Medical Epidemiology at Monash College. “Leisure runners have decrease charges of knee osteoarthritis in comparison with individuals working at an elite or aggressive degree, and in comparison with individuals dwelling a extra sedentary life-style.
