The main objectives of this study are to confirm the long-term safety, performance, and clinical benefits of the G7 Freedom Constrained Vivacit-E Acetabular Liners in primary and revision total hip arthroplasty. The primary endpoint is defined by the survival of the implant system at 10 years, which is based on removal of the study device and will be determined using the Kaplan-Meier method. The safety of the system will be assessed by monitoring the frequency and incidence of adverse events. Relation of the events to the implant, instrumentation and/or procedure should be specified.
