Is Tibiofemoral or Patellofemoral Alignment or Trochlear Morphology Associated With Patellofemoral Osteoarthritis? A Systematic Review

There is strong evidence that PFOA is associated with both trochlear morphology and frontal plane knee alignment, while evidence is limited but consistent in the sagittal and axial planes. These findings suggest that alignment should be evaluated clinically in individuals with PFOA. Clinical interventions targeting knee alignment warrant further investigation.
