What is the MDC for IKDC 2000 in PFPS?

• A. 8.5
• B. 12.2
• C. 6.0
• D. 10.0

Answer: (A)

Minimal detectable change is the smallest amount of score change that exceeds measurement error with a given level of confidence. For the IKDC 2000 in patellofemoral pain syndrome, the MDC is 8.5 points on the 0–100 scale. This means a change of 8.5 points or more is likely a real improvement (about 95% confidence) rather than just random fluctuation or measurement noise. Changes smaller than that could be due to the instrument’s variability. Remember, MDC focuses on the instrument’s precision, while the MCID (not asked here) concerns the amount of change patients themselves consider meaningful. The IKDC 0–100 scale is used to assess knee symptoms and function, with higher scores indicating better function.
