  1. Quantitative measurements include: posterior horn width (PH_Wid), anterior horn width (AH_Wid), posterior horn length (PH_ Len), anterior horn length (AH_ Len), posterior horn to anterior horn distance (PA_Dis), lateral peripheral horn thickness (LPH_Thic), lateral peripheral horn width (LPH_Wid), cover area (Cov_Area), and coverage percentage (Cov_Pct) on tibial plateau, ratio of the distance between horns to the horn length (RDL), contact area (Con_Area) with the femur, and total contact area (Tcon_Area), which sums the contact area with the femur and the area of exposed cartilage. The 1st and 3rd PMVs were found to correlate with height, weight, femoral condyle width, and body mass index.
