Abstract

The purpose of the study was to evaluation of the knee lateral collateral ligament (LCL) stability of normal males and females in twenties by using digital telometer. The volunteer subjects agreed the research goal and were 31 normal adults(16 male: $21.1{\pm}1.5$ years, 15 female: $21.2{\pm}1.2$ years) who have not got any illness regarding their knee. X-ray images were taken varus stress on medial femorotibial joint space using by digital telometer, and grade of pain was surveyed. We measured the joint space width (JSW) in the digital radiology. As a result, the JSW of male group were $5.60{\pm}0.76$ mm and JSW of female group were $5.05{\pm}0.55$ mm (p=0.022) on the neutral state of the knee. Based on the result of varus stress on the knee, female group showed much widen than male group but it was not significant difference (p>0.05). When increased varus stress on the knee, all groups were felt pain from 17 daN to 19 daN. The result could be valuable when the varus stress on the LCL by using the digital telometer.
