Correlation between changes in the KOOS symptoms subscore from 2 years (T1) to 8 years (T3) after ACLR and changes in the anterior-posterior position of KCOR from 2 years (T1) to 4 years (T2) after ACLR. An anterior shift in KCOR over time is shown as positive, and a worsening outcome in KOOS symptoms subscore at 8 years is shown as negative. ACLR, anterior cruciate ligament reconstruction; KCOR, knee center of rotation; KOOS, Knee injury and Osteoarthritis Outcome Score.
