Is running bad for my knees is a common question physical therapist are often asked.
Thankfully there has been a recent systemic review and meta-analysis that gives us answers and insight. Non-runners have about a 10% incidence of knee osteoarthritis (OA), competitive runners 13% incidence, and lastly recreational runners (the category which most all of us fall into) have a 3.5% incidence of knee OA.
This means the risk of developing knee OA is not a reason to stop running or never start.
Recreational running is healthy and prevents the development of arthritis in the lower extremities. Here is an easy to read info graphic summarizing the recent study.
If any motivation is needed, here is a recently popularized image of a 70 year old triathletes leg vs. a 74 year old sedentary individual.
