Clinical Trial Summary

The main objectives of this study are to confirm the long-term safety, performance, and clinical benefits of the G7 Acetabular Shells when used with the Vivacit-E and Longevity HXLPE liners and instrumentation in primary and revision total hip arthroplasty.

Description:

The primary endpoint is defined by the survival of the implant system at 10 years, which is based on removal or intended removal of the study device and will be determined using 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 either implant or instrumentation should be specified. The secondary endpoints are the assessment of performance and clinical benefits by recording patient-reported clinical outcomes measures (PROMs) as well as radiographic outcomes (if available).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Survival of the study device (liner); whether or not it is still implanted in the subject	Survivorship will be based on revision or intended revision of the study device (liner).	At 10 years
Primary	Adverse Event (safety)	Safety will be evaluated by monitoring the frequency and incidence of device related adverse events or unanticipated adverse device effects in investigational subjects.	At 10 years
Secondary	Pain and Function using Modified Harris Hip Score	Pain and function will be measured using the Modified Harris Hip Score self assessment. The overall score runs from 0-100 with 100 representing the best outcome.	At 10 years
Secondary	Pain and Function using Oxford Hip Score	Pain and function will be measured using the Oxford Hip Score self assessment. The overall score runs from 0-48 with 48 representing the best outcome.	At 10 years
Secondary	Patient Quality of Life using EQ-5D-5L Descriptive System	Perceived qualify of life will be measured using the EQ-5D-5L Descriptive System - comprises mobility, self care, usual activities, pain/discomfort, anxiety/depression. Each question in this section has an overall score of 1-5 with 1 representing the best health.	At 10 years
Secondary	Patient Quality of Life using EQ-5D-5L EQ visual analogue scale	Perceived qualify of life will be measured using the EQ visual analogue scale (EQ VAS) - records the respondent's self-rated health on a vertical, visual analogue scale. This section has an overall score of 0-100 with 100 representing the best health.	At 10 years
