What is the MDC for IKDC 2000 in ACL?

• A. 12.2
• B. 8.5
• C. 9.0
• D. 15.0

Answer: (A)

Minimal Detectable Change (MDC) is the smallest amount of change that likely reflects a real difference beyond measurement error, usually calculated at 95% confidence. For the IKDC 2000 in ACL patients, scores run from 0 to 100 with higher scores meaning better knee function. The MDC value around 12 points (about 12.2) is the threshold at which you can be confident that a patient’s change reflects true improvement or decline rather than just measurement noise. So, a change of roughly 12 points on the IKDC 2000 in an ACL context is needed to claim a real, measurement-error-free change. The other numbers fall short or exceed typical MDC estimates and don’t align with the established MDC_95 for this population. For example, a 12-point change is the point where you’d start to interpret the change as real, whereas smaller changes could just reflect variability in the measurement process.
