My left knee hurts. When I put weight on it with my leg bent, like when I get out of the car, I feel a dull pain in my knee. My doctor and physical therapist have given me a diagnosis of patellofemoral pain syndrome, also known as “runner’s knee” or patellar knee-tracking syndrome. Simply put, my kneecap doesn’t run smoothly up and down its track—a groove called the trochlea.
Anyone can get patellofemoral pain syndrome, but for some reason it is more common in women than men—especially in mid-life women who’ve been running for many years. The problem, say researchers who just published a study in the journal Gait and Posture, is that lots of “mature” women develop alignment problems with their knees. The researchers compared younger female runners to older female runners and found misalignment of the knee to be much more common in the older women. Some knees sagged inward, others bowed outward or were rotated.
When the alignment is off, the kneecap can’t smoothly follow its vertical track as the knee bends and extends. This causes wear and tear on the joint. That leads to overuse injuries like runner’s knee and, down the line, osteoarthritis, which can really put a cramp in a runner’s career.
My physical therapist recommended that I (more…)
