Case-control study defines MCID and PASS for knee microfracture, highlighting predictive factors for outcomes.
Key Points
The research aims to establish the MCID and PASS for knee microfracture at a minimum 5-year follow-up and explore predictive factors for achieving these outcomes.
Retrospective case-control study of patients who underwent isolated knee microfracture from 2013 to 2018.
Distribution-based and anchor-based methods determined MCID and PASS thresholds, respectively.
Multivariate logistic regression identified factors influencing MCID and PASS achievement.
IKDC MCID threshold was 11.13 with a 68.57% achievement rate.
KOOS Pain PASS threshold was 85.54 with a 51.43% achievement rate.
Factors such as lower BMI, smaller lesion sizes, and lower K-L grades were predictive of achieving MCID and PASS.
