Challenge of Normality Evaluation by using Micro-Size Tension Measurement Device in Anterior Cruciate Ligament Reconstruction

Abstract

Anterior Cruciate Ligament (ACL) is one of the important ligaments in the knee. The ligament connects the femur and tibia, and has a role to prevent an excessive forward movement of the tibia. In the clinical sports medicine, ACL reconstruction is often preformed about the injured knee. The ACL reconstruction aims to recover the function of the knee. Although some study have reports tension pattern of the reconstructed knee during knee bending, no reports have reported an evaluation method of the normal tension pattern. This study tries to define the normality of the normal knee in considering the tension pattern. The experiment used an imitation bone with an imitation ligament for measuring the tension pattern by using our developed micro-measurement system, and evaluated the normality of the tension pattern. Future works are to apply this evaluation to cadaver knees.
