Tend to be a bit worried that running will cause you knee trauma? Don’t be!
How to Prevent Knee Trauma While Running
Firstly, lets discuss the main cause of outer knee pain when running.
There is evidence implicating that outer knee when running is caused by excursions of the knee such as increased knee internal rotation.
Meardon et al. found that runners with outer knee pain had greater knee internal rotation compared with healthy runners. Moreover, the runners in these studies wore standard running shoes whereby researchers have long suspected that excessive under-foot cushioning disrupts biomechanics and might have a part in triggering greater knee excursion.
Barefoot Stabilizes the Knee
Knee excursion is less pronounced in barefoot running. Perl et al. found that barefoot runners had nearly a 9% reduction in knee excursion compared to shod runners, suggesting that barefoot running is clinically useful for outer knee pain management.
And, from a metabolic perspective, barefoot running might reduce muscle costs because the quads contract less when knee excursion is minimized.
Another trigger of outer knee pain when running is knee extension at touchdown.
- Knee extension typically occurs in conjunction with a heel strike landing, which causes the IT band to slope laterally when passing over the lateral epicondyle of the femur to the lateral condyle of the tibia (Fairclough et al.).
This may be less pronounced during barefoot running, which utilizes a forefoot strike landing and more knee flexion instead of knee extension at touchdown (Lieberman et al. 2010; Nigg,1986).
The Take Home Message
Discerning how much of an influence barefoot or minimalist running have a part in reducing outer knee pain is complicated, however reduced knee excursion appears to occur in the absence of shoe cushioning. What is evident is that there is a symphony of moving parts to make outer knee pain happen when the standard running shoe is worn during running. Because receptors responsible for the perception of pressure and pain are more responsive in barefoot and minimalist running, proves beneficial to improve balance and joint-stability, offering protection from outer knee pain.

BSc Neurobiology; MSc Biomechanics candidate, ultra minimalist runner & founder of RunForefoot. I was a heel striker, always injured. I was inspired by the great Tirunesh Dibaba to try forefoot running. Now, I'm injury free. This is why I launched Run Forefoot, to advocate the health & performance benefits of forefoot running and to raise awareness on the dangers of heel striking, because the world needs to know.
