Characterization of the different prosthesis models.
Polyethylene is always exposed to wear. The more punctual and asymmetric the force on the surfaces, the stronger the wear. Thus, fatigue wear is more often found in unconstrained prostheses. In regard to wear problems, a prosthesis should have an axis that avoids fatigue wear and two polyethylene parts on the tibial plateau.
