Which exercise wins for knee pain? study puts clam shells and quad moves to the test

This study compared two types of exercises—clam shell exercises (for hip muscles) and short arc quadriceps exercises (for thigh muscles)—in 34 adults aged 18-40 with patellofemoral pain syndrome, also known as runner's knee. Participants were randomly assigned to one exercise group and did the exercises for several weeks. The goal was to see which exercise better reduces knee pain, improves daily function, and boosts quality of life. Results may help therapists choose the best exercise for kneecap pain.
