Which of the following best describes the wear characteristics of metal-on-metal articulations?
Mechanical impingement typically occurs at a lower range of motion compared with metal-on-polyethylene articulation
Due to the larger head sizes that are used in metal-on-metal articulations, impingement occurs at a higher range of motion compared with metal-on-polyethylene
A decreased volume of particles are emitted compared with conventional polyethylene liners
A decreased volume of smaller particles are released as a result of metal-on-metal articulation wear.
They exhibit higher linear wear rates when compared with conventional polyethylene liners
Metal liners exhibit decreased wear compared with conventional polyethylene liners
Larger particles are released as a result of the articulation wear
Smaller particles are released as a result of articulation wear
