Does Long-Distance Running cause Osteoarthritis?
Most studies have shown that hip and knee arthritis is not more common in recreational runners. A study in 2017 combined and analyzed the data of 17 previous studies, to compare the rates of hip and knee arthritis in recreational, competitive, and non-runners. The study found that:
Recreational runners had a lower rate of arthritis, 3.5%.
Competitive runners had a rate of 13.3%.
and non-runners/sedentary individuals had a rate of 10.2%.
Competitive runners were professional or elite athletes, or participated in international competitions. The results show that a long duration of elite level running, or a sedentary lifestyle, are both linked with higher rates of knee and/or hip arthritis. It is not possible to determine if the running caused these results, or if they were also impacted by other factors. However, this study shows that running at a recreational level does not increase the risk of hip and knee arthritis. (1)
