Magnetic Resonance Imaging and Radiographic Patellar Height Ratio Measurement Reliability Is Not Degraded by Skeletal Maturity or Patellofemoral Instability.
PURPOSE To identify the most reliable patellar height ratios (PHRs) between and within imaging modalities and evaluate whether skeletal maturity or patellofemoral instability (PFI) diagnosis impacts the PHR reliability. METHODS A radiologic database of lateral knee radiographs and magnetic resonance imaging (MRI) stu...
