| 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
