- PATELLOFEMORAL SYNDROME
Pain under the kneecap that worsens from running, walking down stairs or sitting with bent knees for long periods of time could be a sign of patellofemoral syndrome, also known as “runner’s knee.” You may also hear a crunching, creaking or grating sound. “You can get this from running, jumping or squatting,” says Luga Podesta, M.D. A change like an increase in running mileage, can contribute to pain. Patellofemoral syndrome occurs when the bones in the lower leg are not lined up perfectly, which causes an abnormal gliding between the patella (kneecap) and femur (thigh bone).
This misalignment can lead to wear and tear between the cartilage and surfaces of the bones, causing pain. HOW TO STAY SAFE: Keep knees healthy with exercises that strengthen quadriceps and hip flexors. Seated and lying leg raises are often prescribed for strengthening the quadriceps. Also avoid kneeling or squatting repeatedly.
