The Facts on Runner's Knee:
What Is Runner’s Knee?
Pain in your knees, especially during bending, could be runner’s knee. It’s less of a specific kind of injury and more of a broader category of conditions that has many causes.
More specifically, Patellofemoral Pain Syndrome, is pain between your kneecap and femur, or thigh bone, specifically in the space where they meet. And while it’s named for the many runners who’ve experienced it, you don’t have to be a runner to have runner’s knee. If you spend a lot of time bending your knees to pick up things – or even just like to walk a lot – you can experience runner’s knee pain.
What Causes Runner’s Knee?
Repeatedly running and jumping can stress out your knees, irritating the nerves of your kneecaps or the overstretched tendons that hold them in place.
For some, misalignment can also cause stress to be distributed unevenly in the knee joint, causing pain in specific areas.
