What level of evidence supports hip and knee based exercise for PFPS?

• A. Strong evidence
• B. Moderate evidence
• C. Weak evidence
• D. No evidence

Answer: (A)

In PFPS, strengthening the hip and knee together has strong evidence behind it. The reason is that PFPS pain and dysfunction are closely linked to how the hip moves and stabilizes the leg during activities. Strengthening hip abductors and external rotators, along with knee and quadriceps exercises, improves neuromuscular control and knee alignment during dynamic tasks, which tends to reduce patellofemoral joint stress.

This conclusion comes from multiple high-quality randomized trials and meta-analyses that consistently show greater pain relief and better function with hip/knee–focused programs compared with knee-only or control interventions, with benefits lasting into follow-up periods. Because of the breadth and consistency of these findings, the level of evidence is categorized as strong.

If you see other options suggesting only moderate, weak, or no evidence, remember those would not fit the breadth of consolidated research showing clear positive outcomes with this approach.
