International Knee Documentation Committee (IKDC)
A committee of international knee experts stewarded by AOSSM and our members created the International Knee Documentation Committee (IKDC) Subjective Knee Form. The IKDC form
is knee-specific, patient-reported outcome (PRO) that measures symptoms, function, and sports activity. The form is a reliable and valid knee-specific measure of symptoms, function, and sports activity appropriate for patients with a wide variety of knee problems. The use of this instrument will permit comparisons of outcomes across groups with different knee problems.
A modified version of the IKDC Subjective Knee Forms (Pedi-IKDC) was developed for use with children and adolescents between the ages of 10- and 18-years-old. The reliability and validity of the Pedi-IKDC are acceptable in a population of young patients with a variety of knee disorders.
AOSSM has several translations of the IKDC available.
