We recommend incorporating various covariates (e.g., most importantly ACL injury status, comorbidities [e.g. osteoarthritis, concomitant ligament injuries, etc.], kinesiophobia, dynamic knee stability measures, physical activity level, self-reported outcome measures, knee laxity, time since surgery/injury) while analyzing the relationship between multiplanar knee angles/moments and thigh muscle CCIs/CCRs or temporal parameters (EMG onsets and duration of co-contraction of muscle pairs). Here, ACLY is linked to osteoarthritis.
