Topographic localisation of insertion of the anterior cruciate ligament

Abstract

INTRODUCTION: Determining the center of tibial insertion of the anterior cruciate ligament is important during reconstruction ligament. AIM: Determining the center of insertion of the anterior cruciate ligament on the anterior intercondylar area relate to anterior and medial edge of the upper end of tibia. MATERIAL AND METHODS: The messurement has been done on 102 tibia. We measured distance from the center of ACL to anterior and medial edge of the uper part of tibia, and the lenght and the width of the tibial insetion. Also, we showed the procentual ratio these distances with medio-lateral and anteroposterior diametar of upper tibial part. RESULTS: The distance between the centre of attachment and medial edge is at 39% from entire latero-medial diametar, while the distance from anterior edge is at 31% from entire anterio-posterior diametar. The possitive correlation between the distance of centar of the anterior cruciate ligament from anterior and inner edge (r = 0.366, p) was found. CONCLUSION: The center of the attachment of the ACL at anterior intercondylarl area is at 1/3 of antero-posterial diametar behind the anterior edge of the upper part of tibia and 2/5 of latero-medial diametar inside from the medial edge.
