This is a new version of the initial IKDC proposed by the ESSKA (European Society for Sports traumatology Knee Surgery and Arthroscopy) and the AOSSM (American Orthopedic Society for Sports Medicine), little used previously owing to its complex method of calculation.
This self-assessment questionnaire is divided into three parts (symptoms, sports activities, function) and gives a score between 0 (worst) and 100 (best). This result is interpreted as a measurement of the capacity of the function, such that the highest results represent the highest performing levels of the function and the lowest levels of the symptoms. A result of 100 means that there is no limit to the daily activities and sports and that there are no symptoms.
The standards have been calculated according to age and sex [3]:
. for men, 18-24 years=89 +/- 18, 25-34 years=89 +/- 16, 35-50 years=85 +/- 19, 51-55 years=77 +/- 23;
. for women: 18-24 years=86 +/- 19, 25-34 years=86 +/- 19, 35-50 years=80 +/- 23), 51-55 years=71 +/- 26.
Thus in a young population, a KDC of over 70% is considered necessary to resume sport.
