Patellofemoral Pain Syndrome with Dynamic Knee Valgus on Single-Leg Squat
A subset of patients with patellofemoral pain syndrome (PFP) display inward knee collapse — dynamic knee valgus — when performing a single-leg squat. This movement pattern identifies a distinct subgroup that may warrant a specific treatment approach.
Clinical Scenario
Patient presents with patellofemoral pain and demonstrates dynamic knee valgus on single-leg squat testing. Although dynamic knee valgus does not predict PFP risk in the general population, its presence on single-leg squat identifies individuals who may respond to a targeted intervention.
Treatment Approach
For patients in this subgroup, management involves a movement-based approach focused on correcting lower-limb mechanics during functional tasks.
