Abstract:

In this project, we compared knee laxity and 3-D knee kinematics after ACL reconstruction on cadaver knees using (1) bone–patellar tendon–bone two-tunnel; (2) synthetic ligament two-tunnel; and (3) synthetic ligament “over-the-top” technique. We used a computer assisted system, based on the acquisition of the knee's movement with magnetic sensors (Polhemus, Vermont, USA). The use of personalised three-dimensional (3D) models of the bones enabled us to ensure a reproducible measurement of three-dimensional kinematic and laxity parameters. Our results showed that even when knee laxity was restored to normal, 3D kinematic measurements revealed that the reconstructions tended to under or over-constrain the knee's movement. This study shows that 3D kinematics is a complementary measurement that can be useful to get a better comprehension of the knee's function after ligament reconstruction.
