G7 Acetabular System With Vivacit-E or Longevity Liner PMCF Study

December 22, 2023 updated by: Zimmer Biomet

Global, Multicenter, and Prospective Post-Market Clinical Follow-Up Study of the G7 Acetabular System With Vivacit-E and Longevity Highly Crosslinked Polyethylene (HXLPE) Liners & Instrumentation

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.

Study Overview

Detailed 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).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

16 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • Patient must be a legal adult who has reached full skeletal maturity.
  • Patient must be treated for one of the following indications:
  • Noninflammatory degenerative joint disease including osteoarthritis and avascular necrosis
  • Rheumatoid arthritis
  • Correction of functional deformity
  • Treatment of non-union, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement, unmanageable by other techniques
  • Revision procedures where other treatment or devices have failed
  • Patient must be able and willing to complete the protocol required follow-up visits.
  • Patient must be able and willing to sign the Institutional Review Board or Ethics Committee (IRB/EC) approved informed consent.

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Other: G7 Shell with Vivacit-E and Longevity Highly Crosslinked Polyethylene Liners
Up to 300 hips globally will be implanted with a G7 Shell and either the Vivacit-E or Longevity Liner. The liner used by each site will be identified at start-up.
This is a dual cohort study in which 150 subjects will receive the Vivacit-E (HXLPE) Liner and 150 subjects will receive the Longevity (HXLPE) Liner.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Survival of the study device (liner); whether or not it is still implanted in the subject
Time Frame: At 10 years
Survivorship will be based on revision or intended revision of the study device (liner).
At 10 years
Adverse Event (safety)
Time Frame: At 10 years
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pain and Function using Modified Harris Hip Score
Time Frame: At 10 years
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
Pain and Function using Oxford Hip Score
Time Frame: At 10 years
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
Patient Quality of Life using EQ-5D-5L Descriptive System
Time Frame: At 10 years
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
Patient Quality of Life using EQ-5D-5L EQ visual analogue scale
Time Frame: At 10 years
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
