The Evaluation of Usefulness New Assistant Device to Observe Posterior Cruciate Ligament Rupture and Patellofemoral Joint Injury in Emergency Patient

초록

This study evaluates usefulness of the developed assistant device by taking projection of patellofemoral joint in emergency patients who were doubt posterior cruciate ligament injury in knee joint. The subjects of experiment were patients who visited Eul-Ji University Hospital due to knee injury from January 2006 to December 2006. Seventeen patients, who took the Knee post stress view, Knee merchant view, Knee Seo's view to use assistant device and Knee MRI. To make assistant device of 170×50×70cm, we evaluated its usefulness by measuring posterior dislocation of tibia. Seo's view is more accurate to make judgment of posterior cruciate ligament injury than original knee post stress view. Interval difference of posterior dislocation of original knee post stress view is 6.17± 3.04 and Seo's view is 8.74± 4.47The results show injury of patellofemoral joint, vertical fracture of patella and posterior cruciate ligament injury by taking a projection using Seo's view. Therefore, it is useful to take projection earlier than talome‐ter and MRI in emergency patients who were doubt posterior cruciate ligament injury in knee joint.
