FINITE ELEMENT ANALYSIS OF A RETRIEVED CUSTOM-MADE KNEE PROSTHESIS

Analysis of a below-knee patellar tendon-bearing prosthesis: a finite element study.

In this study, a finite element (FE) model of a below-knee prosthesis of patellar tendon-bearing (PTB) design, and several altered variations of the model have been constructed. A load of approximately 1.5 times normal body weight (984 N) was applied at the heel of the model to simulate heelstrike conditions. The "base" model was then analyzed and revised iteratively until a model which provide...

Systematic Analysis of Painful Total Knee Prosthesis, a Diagnostic Algorithm

The role of custom-made prosthesis for temporomandibular joint replacement

Alloplastic temporomandibular joint replacement (TMJ TJR) presents unique problems due to the integral and multifaceted roles this joint plays within the stomatognathic system to establish and maintain appropriate mandibular function and form. The TMJ not only acts as a secondary mandibular growth center pre-puberty, but is also crucial in maintaining proper mastication, speech, airway support ...

Dynamic Finite Element Analysis of Mobile Bearing Type Knee Prosthesis under Deep Flexional Motion

The primary objective of this study is to distinguish between mobile bearing and fixed bearing posterior stabilized knee prostheses in the mechanics performance using the finite element simulation. Quantifying the relative mechanics attributes and survivorship between the mobile bearing and the fixed bearing prosthesis remains in investigation among researchers. In the present study, 3-dimensio...

Tridimensional titanium-printed custom-made prosthesis for sternocostal reconstruction.

A broad range of materials have been described for sternal reconstruction in order to guarantee not only the best preservation of respiratory mechanics, but also adequate mediastinal protection and acceptable cosmetic results. Today, titanium implants are preferred by many surgeons because of their optimal features. As a step forward, tridimensional (3D) laser sintering printing techniques allo...
