Abstract
This Matters Arising questions the MCID threshold for the Knee Society Score in Xiaodi Liu et al.’s study, noting that it represents an excessively large proportion of the total score and may not accurately capture the minimal meaningful change perceived by patients. We suggest adopting MCID thresholds defined by Wu et al. or Alejandro et al., derived from patient-reported satisfaction and supported by robust sample sizes.
