Basic Knowledge for Rehabilitation after Reconstruction of the Cruciate Ligament of the Knee from the Viewpoint of Mechanical Stress in the Tibiofemoral Joint

-For adequate muscle strengthening exercises in the lower extremities-

Abstract

This article describes the relationship between the muscle strengthening exercises for the lower extremities and the traction load on the cruciate ligament of the knee. In particular, the traction load calculated by means of the mathematical model of the knee joint is introduced in this article. It is considered that understanding of the kinetic information on the knee joint during muscle strengthening is helpful for therapist in guiding rehabilitation after cruciate ligament reconstructive surgery.
