Modification of joint prosthesis surfaces by ultrashort pulse laser treatment for improved joint lubrication

Current Directions in Biomedical Engineering, 2019
Endoprostheses such as hip replacements are subject to wear. Lubrication of the joint interface plays a key role in the wear process, but the mechanisms of lubrication is challenging to understand. The main issue is the three-body abrasion which leads to

THREE-DIMENSIONAL MODEL OF A HIP PROSTHESIS

Journal of Industrial Design and Engineering Graphics, 2019
Serious pathological problems of the hip joint can be solved surgically, in some cases by joint prosthesis. For this reason, it is very important to be able to shape, in a first phase, the components of the prosthesis, which can then be tested virtually.
