Abstract

Background: The knee joint is the most commonly injured of all joints and the anterior cruciate ligament (ACL) is the most commonly injured ligament. Anatomical graft placement is one of the major challenges in ACL reconstruction. Three-dimensional (3D) reconstruction of computed tomography (CT) images is currently the best method to determine whether the ACL tunnel and graft is positioned correctly. This study was done to calculate parameters of femoral tunnel in terms of femoral tunnel diameter, femoral tunnel length, femoral tunnel position based on Bernard and Hertel grid (Quadrant method) and the angle between a line drawn along the femur diaphysis and the femoral tunnel (femoral tunnel-femur diaphyseal angle/coronal angle/coronal obliquity) and to compare the results of femoral tunnel parameters measured with current literature.
Aims and Objectives: To Evaluate the Femoral Tunnel After Arthroscopic Anterior Cruciate Ligament Reconstruction.
Materials and Methods: This is an observational cross-sectional study conducted in the Department of Orthopaedics, H.B.T. medical college and Dr. R.N. Cooper municipal general hospital, Mumbai, on 39 patients of age group of 19-52 year who underwent arthroscopic ACL reconstruction over a period of 1 year.
Results: Most of patients had femoral tunnel diameter between 7.5-8.5 mm and length of 3-4 cm and femoral tunnel-femur diaphyseal angle of 30-40 degree. Most patients had position of femoral tunnel along high to low axis of 28-34% and position of femoral tunnel along deep to shallow axis of >27%. Femoral tunnel position along high to low axis and deep to shallow axis warren anatomical.
Conclusion: Low percent of ACL reconstruction were in recommended anatomical position. CT scan is a very good tool to analyse tunnel position after ACL reconstruction.
