Post-Operative Assessment of an Implant Fixation in Anterior Cruciate Ligament Reconstructive Surgery.

The article discusses a study that assessed the performance of interference screw fixation in anterior cruciate ligament (ACL) reconstructive surgery. Topics include the use of a hyper-elastic material model in modelling the tendon graft and evaluating its elongation while undergoing continuous and cyclic tensile loading, the use of the finite element based numerical model in examining the rigidity of the interference screw fixation, and the three-dimensional (3D) modeling of the tibia.
