AB  - BACKGROUND: The International Knee Documentation Committee Subjective Knee Form 
      (IKDC-SKF) is a knee-specific patient-reported outcome (PRO) measure that is 
      commonly used to evaluate patients with various knee disorders. The Thai version 
      of the IKDC-SKF (Thai IKDC-SKF) was shown to have good validity and reliability; 
      nonetheless, no data regarding its responsiveness are available. PURPOSE: To 
      evaluate the responsiveness of the Thai IKDC-SKF for assessing patients with 
      anterior cruciate ligament (ACL) injury and determine the minimal clinically 
      important difference (MCID) for this PRO measure. STUDY DESIGN: Cohort study 
      (diagnosis); Level of evidence, 3. METHODS: This prospective study included 
      ACL-injured patients who were scheduled for ACL reconstruction (ACLR) at a single 
      institution. The patients completed the Thai IKDC-SKF at the baseline and the 
      6-month postoperative follow-up. The global rating of change scale was an anchor 
      question that evaluated patients' overall perception of a clinical change 
      compared with their preoperative condition. The effect size and standardized 
      response mean were calculated. The MCID was identified with an anchor-based 
      approach by plotting a receiver operating characteristic curve and calculating 
      the value that maximized the Youden index. RESULTS: Of 59 enrolled patients, 53 
      patients (89.8%) completed the preoperative and 6-month postoperative Thai 
      IKDC-SKF. The mean (+/-SD) age of the participants was 32.3 +/- 10.3 years, and 86.8% 
      were men. The mean Thai IKDC-SKF score improved significantly from preoperatively 
      to the 6-month follow-up (from 56.3 +/- 14.9 to 70.8 +/- 14.1, respectively; P < 
      .001), with an effect size of 0.975 and a standardized response mean of 0.977. A 
      receiver operating characteristic curve was generated to determine the ability of 
      the Thai IKDC-SKF to distinguish between improved patients and unimproved 
      patients, and the area under the curve was 0.80 (95% CI, 0.68-0.92), which was 
      considered excellent. The MCID was 15.5, which yielded a sensitivity and 
      specificity of 0.55 and 1, respectively. CONCLUSION: This study confirmed the 
      responsiveness of the Thai IKDC-SKF for detecting a clinical change in 
      ACL-injured patients after ACLR. The identified MCID of 15.5 can be used to 
      calculate the significant clinical change and sample size in future studies.
