Abstract
With the growing awareness of environmental protection, the popularity of cycling also grows. The knee ligaments plays an important role not only about joint stability but also transmit the relative kinematics information between the femur and the tibia. Exercises with cycles widely applied to the rehabilitation of the lower extremities especially in patients with cruciate ligament injuries.
Finite element analysis procedure consists of the geometry model reconstruction, using computer tomography for bone and magnetic resonance imaging scan for ligaments information, the ligament material properties definition, using the KT-2000 knee ligament arthrometer, the boundary condition variation, using fluoroscopy and computer models image registration. The objective of this study was to analysis the stress distribution and the force of the in vivo knee ligaments in normal young subjects using validated finite element analysis procedure. It will be helpful to use in the treatment, rehabilitation and prevention.
The finite element analysis showed that PCL was mainly stretched and stressed during cycling and there were no effect on ligaments force, stress distribution under unloaded and loaded. Bicycling will not appropriate for PCL injury patients.
