Assessment of normal pediatric knee ligament laxity using the genucom.
Normal values for knee ligament laxity in children have never been defined. In this study, using the Genucom Knee Analysis System, we examined 464 normal knees in 232 children aged between 7 and 14 years. A progressive decrease in the absolute value of both translation and rotation laxity was evident as the age of the child increased. The children's percentile for height and weight within their age group influenced their measured knee ligament laxity. No significant difference was seen between right and left knees of the same patient. There was no clinically significant difference between the measured laxity of the knees of boys and girls.
