It’s warm outside, let’s go running!


In clinical practice, patients frequently tell me that they are worried about the long-term impact on their knees from running. In particular, patients are worried about the potential link between running and the development of knee osteoarthritis (OA).  Those patients that already have knee OA are concerned about worsening the condition of their knees if they continue to run.


Fortunately, good research has shown that running has no negative impacts on knee cartilage in people without knee OA and may actually be protective against the development of osteoarthritis. In fact, the rates of knee OA were higher in sedentary people when compared to recreational runners. Unfortunately, rates of knee OA have been shown to be slightly higher in former elite and professional International runners.


Although there is little evidence right now, the research that does exist appears to show that running with knee OA does not increase the progression of arthritis. Furthermore, running can be extremely beneficial for many other things, including your heart, lungs, muscles, bones, brain, weight loss, depression, the immune system, mood, etc.


My practical advice is to patients is usually this:

  • Start slow – run within your own tolerances. Follow a program
  • Progress distances and pace slowly
  • Focus on long-term, achievable goals!


Do your back, hips, knees, or feet hurt while running? Booking an assessment with a physiotherapist can help to identify and address areas of concern. At Kamloops Physiotherapy and Sports Injury Centre, we can assess how your body moves and identify areas that require attention. We also have a physiotherapist who is certified in running assessments. Read more here:
