Despite common misconceptions, extensive research consistently demonstrates that running does not harm the knees but rather strengthens them. In fact, runners possess healthier and more robust knees compared to sedentary individuals. This article delves into the scientific evidence supporting this claim, dispelling myths and providing a comprehensive understanding of the relationship between running and knee health.
The Evidence: Running Makes Knees Stronger
Numerous studies have examined the impact of running on knee health, consistently concluding that it does not increase the risk of osteoarthritis or other knee injuries. On the contrary, regular running has been associated with improved knee function, reduced pain, stronger tendons, thicker ligaments and enhanced cartilage health.
A survey by Northwestern University of 3,804 recreational runners who participated in the Chicago Marathon in 2019 or 2021 with questions from how many years they’d been running and their average running paces to whether they had family histories of arthritis found no association between an increased risk for knee or hip arthritis and the number of years someone had been running, the number of marathons completed, their weekly running mileage, nor their running pace.

How Running Strengthens Knees
Running exerts a gradual and controlled load on the knees, stimulating the production of synovial fluid, a natural lubricant that nourishes and protects the joint. This fluid acts as a shock absorber, reducing friction and preventing wear and tear.
Moreover, running strengthens the muscles surrounding the knee, providing stability and support. These muscles, such as the quadriceps, hamstrings, and calf muscles, work together to absorb impact and maintain proper knee alignment.
Running Won't Wreck Your Knees, But...
While running is generally safe for the knees, it's essential to exercise caution and avoid excessive or improper training practices that can lead to injuries. Gradual progression, proper footwear, and listening to your body are key to maintaining knee health.
Benefits of Running for Knee Health
Reduced risk of osteoarthritis
Improved knee function
Decreased pain
Enhanced cartilage health
Stronger muscles surrounding the knee
Improved stability and support
Keep Moving
The evidence is clear: running does not wreck your knees; it strengthens them. By embracing this knowledge, runners can enjoy the numerous benefits of this activity without fear of knee damage. So, lace up your shoes and hit the pavement, knowing that you're not only improving your cardiovascular health but also investing in the long-term well-being of your knees.
Remember: cross training and full ROM lower body exercises are also important factors in maintaining optimal health of the muscle, tendons, ligaments and joints.
