Can Running Cause Knee Arthritis?

You've probably heard at some point that long distance running contributes to the development of arthritis in the knees. According to one large study, long distance running was not linked to knee arthritis, and runners in the study were actually less likely to develop it.

The belief that running leads to knee arthritis is founded on the high impact nature of the exercise and the stress it can put on the knees. Osteoarthritis, particularly in the knee, is one of the most common forms of knee arthritis. OA develops over time as cartilage and joint tissue degrade from overuse. While this can be made worse by activities like running, the study suggests that runners who started with healthy knees were no more likely to develop OA than anyone else.

The study, which examined more than 75,000 participants – all active runners – found no link between running and the development of OA. In fact, the participants were less likely to develop the condition than people who were not active. Exactly why this is the case is still unclear. Researchers are conducting further work to try to understand the relationship between high impact exercise and a lower risk for osteoarthritis. Individual results vary.

Walking has long been the low-impact activity most often recommended to arthritis patients by physicians. It has been studied for its role in helping control weight and keeping joints and muscles limber. Running puts about three times as much force on the joints as walking, which can place someone at a higher risk for injury. Done with good form at a moderate pace, running can be more efficient than walking in terms of burning calories.

Regardless of how these studies shape the way doctors prescribe exercise, one thing remains true: moving your body is beneficial. You don't necessarily need to worry about developing OA from higher impact exercise, though if you wish to err on the side of caution, low impact exercise is always a good option. Talk with your doctor about what is right for you.
