  Purpose

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.

Intervention Details:
    Device: Trident X3 Polyethylene Insert
    The purpose is to evaluate and compare the linear wear rates of the Trident X3 Polyethylene Insert to the control group at 5 years.
Detailed Description:

The study is a prospective, multi-center, historical-controlled clinical evaluation of the Trident® X3® Polyethylene insert. The device is commercially available in the United States where the study is being conducted. The study device, the Stryker Orthopaedics Trident X3 polyethylene insert, is used for the replacement of the bearing surface of the acetabulum to relieve pain, instability, and the restriction of motion due to degenerative bone disease, including osteoarthritis, rheumatoid arthritis, trauma, or failure of other devices. The control device, the Stryker Orthopaedics N2VAC polyethylene insert, is also used for the replacement of the bearing surface of the acetabulum to relieve pain, instability, and the restriction of motion due to degenerative bone disease, including osteoarthritis, rheumatoid arthritis, trauma, or failure of other devices.
