Cohort study investigates KOOS equivalence at 1 and 2 years after ACL reconstruction, indicating no added value in dual assessments.

The aim is to determine if KOOS results at 1 and 2 years after ACL reconstruction are equivalent.
Cohort study utilizing the Swedish National Knee Ligament Register data from 2005 to 2013.
Longitudinal assessment of KOOS values at 1- and 2-year follow-ups.
Used two one-sided test (TOST) method for equivalence with an acceptance criterion of 4.
KOOS scores showed equivalent results across all subscales at 1 and 2 years with significant p-values (<.001).
Mean difference in KOOS scores reported at 1 and 2 years for various domains included: Pain (0.21), Symptoms (-0.54), Activities of Daily Living (0.45), Sports and Recreation (-0.35), and Quality of Life (-0.92).
Findings imply that measuring KOOS outcomes at both 1 and 2 years offers no additional value, though longer follow-ups may still be necessary.

Samuelsson et al. (2017) studied this question.
