Study Summary
The primary objective of the study is to demonstrate the linear wear rates of the Trident® X3 polyethylene insert are superior to a polyethylene control group wear rate at 5 years postoperative. This measurement will be evaluated by comparing digitized images of serial radiographs obtained over a follow-up period of 5-years.
Primary Outcome
Linear wear rates are defined as the annual rate of removal of the polyethylene from the polyethylene insert determined by comparing digitized images of serial radiographs obtained over the follow-up period of 5 years
