International Knee Documentation Committee (IKDC) score calculator

About the score:

Originally published in 1993 in the American Journal of Knee Surgery and most recently revised in 2001 in The American Journal of Sports Medicine, the International Knee Documentation Committee Subjective Knee Form (IKDC) was designed to assess patients with a variety of knee disorders including ligamentous and meniscal injuries as well as patellofemoral pain and osteoarthritis.

The IKDC is a patient-completed tool, which contains sections on knee symptoms (7 items), function (2 items), and sports activities (2 items). Scores range from 0 points (lowest level of function or highest level of symptoms) to 100 points (highest level of function and lowest level of symptoms).
