Traceability needs for geometrical identification of form of biobearings working surfaces and defect of joint cartilage

In this paper the own system for traceability analysis of geometrical estimation of the articulation cartilage defects imaged using magnetic resonance (MR) is presented. There were examined three animals and two human specimen knees using MR and coordinate control machine (CCM). Three dimension modeling and visualization of the defect using finite elements method in the packets were done: Ansys, FEMAP, NE Nastran. Computer tomography was done to verify bone damage. The size of the cartilage defect obtained in MR and CCM were approximately. MR and CCM are the sufficient methods of traceability for imaging of cartilage defects. The quality of the shape imagine and size estimation of the defects depends on the measurement strategy and selection of the best imaging sequences. The described procedure of the MR application to the modeling computed programs like FEMAP, NE Nastran will give the possibility for creation of the virtual imaging of the real articulation cartilage defects. The described procedure of cartilage defects diagnosis can be used as a modern, non-invasion method for preoperative planning of way of treatment.
