Overview

The primary objective of this investigation is to evaluate survivorship at ten years. For this post approval study (PAS), a maximum acceptable hazard of revision is assumed to be a constant 1% per year.

This is a retrospective and prospective, non-randomized study of the Ceramic on Metal(CoM) device. This study will follow each subject through 10 years postoperatively. A total of 250 subjects will be enrolled in the investigation comprised of approximately 150 new PAS subjects and approximately 100 subjects recruited from the investigational device exemption study to the PAS.

Time frame: 10 years

Secondary Outcomes

Metal Ion Levels

A subset of subjects will be measured for serum cobalt, serum chromium, erythrocytes cobalt, erythrocytes chromium, whole blood cobalt, and whole blood chromium levels. These subjects will also be measured for BUN and creatine levels.

Time frame: 5 years, 8 years, and 10 years postoperatively
