Full description

This is a prospective observational multi-center non-controlled study. The primary purpose of this study is to evaluate the clinical and radiographic performance of the G7 Acetabular Cup System in both primary and revision procedures, report safety and survivorship, and document instrument ease of use.

Preoperative and intraoperative data have been collected retrospectively and follow ups have been collected prospectively.

Clinical outcomes included the Harris Hip Score, Oxford Hip Score, and Radiographic Evaluations collected at 3 month, 1, 2 and 5 year follow-up time points. For the 7 and 10 year follow-up intervals, survivorship and adverse events have been collected.
