Abstract

PURPOSE
This study aimed to validate a recent officially approved Korean version of the International Knee Documentation Committee (IKDC) subjective knee form, to determine the standard basis values in a normal Korean population and to use the IKDC for determining the effectiveness of and recovery after an orthopedic procedure.
MATERIALS AND METHODS
Five male subject and 5 female subjects (a total of 10 subjects per group) were included in group I (age of 20~30 years old) and Group II (age over 60 years old), respectively, and the patients were without knee joint disturbance and radiologic/clinical abnormality, and all the subjects were examined by an orthopedic knee surgeon. All the subjects were evaluated with the Korean version IKDC subjective knee form. Spearman's analysis was used to test for significant differences between each group.
RESULTS
The overall result of the Korean version IKDC subjective knee form in group I was 98.3+/-3.7 (88.5~100.0) on average, and it was 100+/-0.0 for the males and 96.6+/-4.9 (88.5~100.0) for the females with no significant differences (p=0.189) between the two gender. The average score of the IKDC subjective knee form in group II was 86.6+/-5.8 (78.2~93.1) and this was 89.6+/-5.4 (80.1~93.1) for the males and 83.7+/-5.1 (78.2~92.0) for the females with no significant difference (p=0.113) between the two genders. But there was statistically significant differences of the score of the Korean version of the IKDC subjective knee form between group I and group II (p<0.0043).
CONCLUSION
We have to consider age differences when using the Korean version of the IKDC subjective knee form, but there are no differences according to gender.
