슬관절 전방십자인대 이완의 단순 방사선학적 계측 = Plain X - ray Assessment of ACL Insufficiency

다국어 초록 (Multilingual Abstract)

Dynamic assessment is a well known technic)ue used in the evaluation of knee joint in.',tabilities. Until now, plain radiographs has p]ayed a limited role in the evaluation of ACL(Anterior Cruciate Ligament) insufficiencics. This study was designed to introduce a new procedure of radiographic assessment of ACL insufficiency. Lateral radio<raphs of knees in maximum extension were taken in 18 cases of ACI. Insufficient knees, and these were compared with those of twenty normal knees. On the lateral view of the knee, two 1ines were drawn along 1) the anterior margin of' femur and 2) Blumensaat's line. Tibial translation was defined as a distance between anterior tibial cortex and the intersection point (FR point) of the two lines, F-line and R-line. Tihial displacement was calculated as a pircentage value of tibial translation vided by the tihial width of the level. The tihial displacement was 4.3+-5.0% in normal knees and 18.0+-4.5% in knees with chronic ACL insufficiency. The difference was statistically significant (p=0.0000).
