About this study

Official title: A Single-center, Randomized, Value Study of VISIONAIRE™ Patient Matched Technology vs. Standard Surgical Instrumentation

This is a single center randomized observational study that evaluates the cost benefit ratio between the use of two types of instrumentation in TKA: standard instrumentation vs. VISIONAIRE™ Patient Matched Technology. This study does not involve treatment or investigational products, as all components are FDA approved and are commercially available.

Read the detailed description

The objective of the current observational study is to assess value of surgical instrumentation following analysis of health economic data. It is hypothesized that patient matched cutting block technology VISIONAIRE™ may reduce TKA operative time, blood loss, surgical error and adverse event risk as well as providing improved mechanical alignment. In order to test this hypothesis, subjects will be randomized to either VISIONAIRE™ or standard TKA instrumentation groups. One site will enroll a total of 38 patients; 19 patients per group. All patients meeting the inclusion/exclusion criteria specified in this protocol will be asked to participate in the study. If the patient consents to participate, they will be enrolled in the study and randomized to one of the two study arms. Patients requiring TKA will be implanted with Legion, Genesis II or Journey BCS (Smith \& Nephew) total knee implant systems. Standard instrumentation will be used to assist the surgeon in placing the implant in the control group. In the VISIONAIRE™ group, standard instrumentation will not be used in the surgery. Patients randomized to the VISIONAIRE™ arm will have an MRI preoperatively that will be used to create the customized cutting blocks. All patients will have an x-ray at each postoperative interval.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Health Economic Criteria

    This study will evaluate the cost benefit ratio between the use of two types of instrumentation in TKA: standard instrumentation vs. VISIONAIRE™. The following will be collected \& reported from the OR and discharge report:

    • instrument tray set-up time
    • operative time
    • blood loss
    • instrumentation requirements
    • discharge disposition
    • ambulatory support on discharge
    • adverse event

    Measured: Up to 6 weeks

Secondary outcomes (1)
  1. Number of Participants with Adverse Events as a measure of Safety and Tolerability

    Radiographic analysis will be conducted to assess preoperative and postoperative mechanical alignment between groups. All perioperative and postoperative surgical or instrument-related adverse events will be recorded during this study.

    Measured: Perioperative & Postoperative (up to 6 weeks)

Questions about this trial

What is this clinical trial studying?

An observational study of Osteoarthritis of the Knee, run by Smith & Nephew, Inc. at 1 site 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 4 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 21 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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.

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?

Health Economic Criteria (time frame: Up to 6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01107769, which also lists 2 linked publications.

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 21 Nov 2011.
