For PFPS, which exercise approach is supported by strong evidence?

• A. Only isometric quadriceps exercises
• B. Always rest
• C. WB and NWB hip and knee based exercises
• D. Only foot exercises

Answer: (C)

For PFPS, the strongest evidence supports a rehabilitation strategy that combines both weight-bearing and non-weight-bearing exercises focused on hip and knee mechanics. Weakness in the hip muscles, especially the abductors and external rotators, can allow dynamic knee valgus during activities, increasing patellofemoral joint stress. Strengthening these hip muscles improves knee alignment during function, which often reduces pain and improves function. Including both non-weight-bearing and weight-bearing exercises allows targeted strengthening early on (non-weight-bearing quad and hip exercises can be done pain-free or with minimal pain) and then progressing to functional, weight-bearing movements that reproduce real-life tasks. This progression helps build neuromuscular control and power through the kinetic chain, from hip to knee to ankle, promoting better patellar tracking during squats, stairs, running, and jumping. Rest alone does not address the mechanics or deconditioning, and exercises targeting only the foot don’t directly influence patellofemoral tracking or hip strength. A comprehensive program that teaches and reinforces loading patterns through both non-weight-bearing and weight-bearing formats provides the most robust evidence for reducing symptoms and improving function in PFPS.
