Which muscles should be targeted for strengthening in patellofemoral pain syndrome?

• A. Increase external rotation of hip
• B. Strengthen VMO and hip muscles; improve lower limb control
• C. Only calf stretching
• D. Avoid exercises entirely

Answer: (B)

Strengthening the muscles around the knee and hip to improve knee tracking and overall lower limb control is the key idea here. In patellofemoral pain syndrome, the patella (kneecap) can mistrack, often because the muscles that stabilize the knee and control the thigh’s motion aren’t doing their job effectively. Strengthening the vastus medialis obliquus (VMO) helps pull the patella medially as it moves, promoting more centralized patellar tracking and reducing lateral stress on the patellofemoral joint. At the same time, building strength in the hip muscles, especially the abductors and external rotators, improves control of the femur as the leg moves. This reduces dynamic valgus (inward knee collapse) and excessive internal rotation of the thigh, which can pull the patella out of alignment during activities like running, squatting, or stairs. With better hip control and a stronger VMO, the knee works more efficiently, and patellofemoral joint stress decreases, easing pain and improving function. Choosing only calf stretching misses the essential hip and thigh stability needed to address patellar tracking. Avoiding exercise entirely deprives the knee of the very strengthening that helps correct malalignment. Increasing external rotation alone isn’t the targeted approach for this condition, since it doesn’t address the combined hip–knee control that stabilizes the patella.
