About this study

Official title: A PROSPECTIVE MULTI CENTER RANDOMIZED CONTROLLED TRIAL TO EVALUATE G7 Acetabular System With CoC ARTICULATION COMPARED TO EXCEED ABT Acetabular System With CoC ARTICULATION IN TOTAL HIP ARTHROPLASTY

Evaluate the safety and effectiveness of patients who received G7 Acetabular system in conjunction with Ceramic on Ceramic articulation and Taperloc Complete Microplasty stem compared to patients who received the Exceed ABT Acetabular system with the same combination

Read the detailed description

This study will be a multi-center randomized controlled study. Eligible patients will be randomly assigned to receive a combination of G7 Acetabular system with CoC articulation and Taperloc Complete Microplasty stem or Exceed ABT Acetabular system with CoC articulation and Taperloc Complete Microplasty stem. Patient demographics, preoperative clinical outcomes, operative information, postoperative clinical outcome, radiographic assessment, incidence of squeaking, incidence of dislocation, implant survivorship and adverse events will be collected prospectively.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • G7Device

    The Biomet G7™ Acetabular System has been designed to provide more options to surgeons for treatment of patients needing total hip arthroplasty, while concurrently simplifying the surgical process with well-designed, modular components and corresponding instruments. The G7™ Acetabular System includes three liner types; ArComXL highly-crosslinked or E-1 Vitamin E-infused polyethylnene and a Biolox Delta (Ceramtec, Plochingen, Germany) ceramic liner.

  • Exceed ABTDevice

    The Exceed ABT Acetabular System has been designed for cementless fixation and consists of an acetabular shell and an acetabular insert. The acetabular insert/bearing includes a tapered outer geometry that matches the inner geometry of the acetabular shell and an inner hemispherical geometry to suit the varying modular head diameters. Inserts/bearings are inserted into the acetabular shell intra-operatively and are available in varying sizes to match the acetabular shell diameters. The insert/bearings are available in Biolox Delta ceramic (CeramTec AG).

Study groups in NCT02340390
Study groupRoleWhat they receive
Hip implant1ExperimentalThe Biomet G7 Acetabular System is a modular acetabular system, offering two types of acetabular shells. The shells are available in either a solid shell design, with an apical plug, or a limited hole with an apical plug and optional screw holes. Components are available in numerous designs and sizes intended for both primary and/or revision applications.
Receives: Device: G7

The acetabular insert/bearing includes a tapered outer geometry that matches the inner geometry of the acetabular shell and an inner hemispherical geometry to suit the varying modular head diameters. Inserts/bearings are inserted into the acetabular shell intra-operatively and are available in varying sizes to match the acetabular shell diameters. The insert/bearings are available in Biolox Delta ceramic (CeramTec AG).

  2. Loosening on its implant

    The presence of signs of loosening on its implant

    Measured: Immediate post-op, 6 months, 1 year, 2 year

  3. Squeaking sounds

    Number of patients with squeaking Sounds

    Measured: 6 months, 1 year, 2 year

  4. Dislocation

    Dislocation at different follow-up visits

    Measured: 6 months, 1 year, 2 year

Questions about this trial

What is this clinical trial studying?

A study testing G7 and Exceed ABT in people with Osteoarthritis Arthritis and Rheumatoid Arthritis, run by Zimmer Biomet at 3 sites in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 26 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

the safety and effectiveness of patients (Harris Hip Score) (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 26 Mar 2019.
