1, To get the success of the human knee meniscus transplantation needs the cooperation of all aspects in non-linear interaction.

2, Objective: To reconstruct a 3D vivo human knee joint model. It could be used for further kinetics and dynamics analysis of the human knee joint.

3, The human knee meniscus is also an opening system rather than the balance at any time and any where.

4, Human knee joint is the biggest and most complex arthroses the human body.

5, The human knee meniscus possesses viscoelastic properties in all directions traction, but its anti-stretching ability is especially strong in longitudinal axis direction.

6, Objective: Analyze the X-ray manifestation of synovial osteochondromatosis in human knee in order to know more about the disease and find its early expressions through X-ray.

7, Optimization computation of 14 mechanism parameters of 4-bar knee joint is used to make it track human knee joint and damper cost minimum energy.

8, The present invention provides genouillere warm-keeping trousers,[http:///human knee.html] which warm up human knee joint by infrared material so as to avoid arthritis.

9, Conclusion Transverse ligament, meniscoperoneal ligament and meniscofemoral ligament existed commonly in human knee joint to protect lateral part of meniscus.

10, Objective To build up animal models with stiff knee which is similar to human knee.
