  1. Baseline and follow-up patellar cartilage volume were presented as mean (SD). Patellar cartilage volume change and annual percentage change in patellar cartilage volume are presented as mean (95% confidence interval). Patellar cartilage volume change = follow-up volume - baseline volume, thus positive values represent an increase in cartilage volume
  2. *Significant difference (p < 0.05). #Adjusted for age, gender, BMI, baseline cartilage defect score, and baseline patellar bone volume. Post hoc was significantly different for 1 isolated ACLR versus controls, 2 isolated ACLR versus combined ACLR, a follow-up versus baseline
