From: Development of a rapid knee cartilage damage quantification method using magnetic resonance images

Spearman correlation
  HKA JSW baseline
Femur CDI (Baseline) 0.34* 0.84*
Tibia CDI (Baseline) 0.21* 0.77*
Tibiofemoral CDI (Baseline) 0.31* 0.87*
HKA JSW change
Femur CDI (Change) 0.29* 0.30*
Tibia CDI (Change) 0.34* 0.40*
