Arms of the Study
Arm 1
Experimental
Total Hip Arthroplasty Treatment Group
This study will enroll (implant) up to 202 hips in total according to the IFU and surgical technique. Of these, up to 135 will be revision hips and up to 67 will be primary hips. This is a dual cohort study (primary and revision); each subject will receive the G7 Acetabular System with the Freedom Constrained Vivacit-E bearing. To minimize potential bias and to maximize our ability to assess inter-site differences, each study site will target up to 27 primary hip arthroplasties and up to 54 revision hip arthroplasties (not exceed 81 implanted hips or 40% of total study population). Each site is encouraged to enroll (implant) both primary and revision subjects.
