Reference no: EM132372690

Background: Total hip replacement using the ceramic-on-metal (COM) hip replacement materials have shown to reduce wear and tear than metal-on-metal (MOM) hip replacement materials.

Hypothesis: As such, we believe that COM hip replacements where the head is ceramic and the liner is metal (CoCrMo alloy) exhibit reduced wear under standard simulator conditions compared to MOM hip replacements.

Methods: COM and MOM hip replacements were tested using a simplified gait simulator for 2 million cycles and the volumetric wear was recorded in mm3/million cycles.

What could be contributing factors to variance? What does that mean in the context of the problem?
