About this study

Official title: Investigational Device Exemption for the Scandinavian Total Ankle Replacement (STAR) - Bilateral Arm

The purpose of this study is to evaluate the safety of the S.T.A.R. device for patients with bilateral disease.

Read the detailed description

The specific objectives are to show that the safety data of the S.T.A.R. ankle arthroplasty is similar for treatment of single ankle disease (as defined in the pivotal study) and bilateral ankle disease. The bilateral disease may be identified at the time of enrollment or may have progressed after enrollment and treatment of the first ankle in the pivotal study.

What participants receive

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

  • Scandinavian Total Ankle Replacement (STAR)Device

    The device has three parts: two metal bearing surfaces (cobalt-chromium alloy) plates with bars that fit into the bone and one plastic (polyethylene) spacer that moves between the metal plates like a ball bearing. The materials in the S.T.A.R. device are the same materials used in total hip and knee implants.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Scandinavian Total Ankle Replacement (STAR) in people with Osteoarthritis and Post-Traumatic Arthritis, run by Link America, Inc. at 5 sites in United States.

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 5 inclusion and 10 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 4 Jan 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Safety endpoints to be measured are: • Device failure or device removal/revision • Radiographically confirmed loosening and migration • Complications (time frame: 12 months). 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 4 Jan 2008.
