About this study

Official title: Single Row Versus Double Row Fixation in Arthroscopic Cuff Repair; a Randomized Controlled Sutdy.

The study will identify if there is a difference of quality of life after surgery between two techniques used in surgery. The two different techniques are either the Single Row Fixation or the Double Row Fixation.

Read the detailed description

Primary Research Question; What is the difference in disease specific quality of life between patients who undergo a repair of the rotator cuff with arthroscopic technique using single-row fixation, versus double-row fixation, as measured by the Western Ontario Rotator Cuff Index (WORC)at one year post op?

Being tested
single row, double row fixation
Keywords
full thickness rotator cuff tear
Medical subject headings

What participants receive

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

  • single rowProcedure or surgery

    This method involves using a single row of anchor(s) to reattach the cuff to the bone.

  • double row fixationProcedure or surgery

    This technique, "double row" fixation, involves adding an extra anchor(s) over the number used for single row fixation. This extra anchor(s) is placed further inside the bone and may help to increase the fixation strength of the repair.

What is being measured

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

  1. Western Ontario Rotator Cuff Index (WORC)

    Do patients who undergo a repair of the rotator cuff with arthroscopic technique using double row fixation have increased disease specific quality of life (measured by WORC) then patients who undergo a repair with arthroscopic technique using single-row fixation? The WORC scale is from 0% to 100%, with a higher value being indicative of better disease specific quality of life.

    Measured: 2 years

Secondary outcomes (4)
  1. Constant Score

    Differences in outcome between the two groups as measured by the Constant score. The constant score ranges from 1 to 100 with a higher value indicative of better shoulder function.

    Measured: 2 Year

  2. ASES Score

    Determination of differences in outcome between the two groups as measured by the American Shoulder and Elbow Surgeons (ASES) score. The ASES score ranges from 0 to 100 with a higher number indicative of better function.

    Measured: 2 Year

  3. Strength Test

    Shoulder strength in forward elevation was measured in kg using a portable scale.

    Measured: 2 Years

  4. Healing Rate

    Percentage of Participants who had healed by 1 year post-surgery as measured using magnetic resonance imaging. If the tendons were in continuity with no evidence of full-thickness tearing, the repair was considered healed (intact).

    Measured: 1 Year

Questions about this trial

What is this clinical trial studying?

A study testing single row and double row fixation in people with Rotator Cuff Tear, run by Ottawa Hospital Research Institute at 1 site in Canada.

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 2 inclusion and 11 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 1 Apr 2020. 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 Canada. 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?

Yes. Results are posted in the registry (first posted 29 Jan 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Western Ontario Rotator Cuff Index (WORC) (time frame: 2 years). 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 NCT00508183, 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 1 Apr 2020.
