| Research Abstract |
Quantitative in vivo analysis of the contact behaviour of articular cartilage of the knee joint enables us to accurately perform the clinical diagnosis of the progress of osteoarthritis as well as to greatly improve the design of the knee prosthesis. The method of contact analysis of the cartilage in the femorotibial joint using an image registration technique has been newly developed. The method consisted of 3D bone models in terms of CT scanning, 3D femoral and tibial cartilage layer models in terms of MR imaging and 2D-3D image matching technique. The method was validated through the experiment on a human cadaveric knee.
