What is the evidence for PFPS and exercise?

• A. No evidence supports exercise for PFPS
• B. There is strong evidence to support the use of WB and NWB hip and knee based exercises in patients with PFPS
• C. Only quad strengthening is beneficial for PFPS
• D. Exercise worsens PFPS

Answer: (B)

Structured exercise programs that strengthen both the hip and knee muscles have the strongest support for PFPS. The patellofemoral joint is influenced by thigh and hip strength and control; when hip stabilizers (like the glutes) are weak, it can alter knee tracking and increase joint stress. Research shows that a combination of hip abductors and external rotators work in tandem with quadriceps strengthening and neuromuscular training to reduce pain and improve function. Both weight-bearing and non-weight-bearing exercises are useful, and clinicians typically tailor progression to pain and function, starting with less provocative movements and gradually adding loading as symptoms allow. This approach captures the evidence that exercise helps PFPS, not only with a single muscle focus but with a comprehensive program that includes both hip and knee strengthening.
