Kneed To Know Basis

Knee “Running’s bad for your knees,” is one of the most common criticisms the activity faces. A new study, however, has revealed the opposite to be true.

A recent report published by Arthiritis Care & Research was not initially intended to study runners. However, eight years after joining the study, subjects were given a physical activity questionnaire revealing that 29.5% had participated in some amount of running in their life.

All subjects underwent radiography (X-rays) of their knees and results found that: “A history of leisure running is not associated with increased odds of prevalent knee pain, ROA, or SOA [symptoms of arthritis]. In fact, for knee pain, there was a dose-dependent inverse association with runners.”

Put simply, those who ran the most had the least knee pain.

First author Grace Hsaio-Wei Lo, M.D, an assistant professor at the Baylor College of Medicine, stated: “This was true across all age groups and for running at any time in one's life. This is the largest study to look at running similar to what the everyday person would do. Also, because it was part of the very large Osteoarthritis Initiative, we used high-quality X-rays and methods of assessing knee symptoms.”

The subjects who continued to run had less knee pain that the ones who had quit. The percentage of runners reporting frequent knee pain were as follows:

  • Non runners - 41.1%
  • Low runners - 34.9%
  • Middle runners - 39.2%
  • High runners - 31.3%
