Trial summary

There are two purpose of this study, first is to find whether arthroscopic rotator cuff repair is changing the appearance of supraspinatus muscle atrophy in each and every patient. Second, is to find how much approximate change one can expect depending on age and tendon retraction Read more about this study

About this study

There are two purpose of this study, first is to find whether arthroscopic rotator cuff repair is changing the appearance of supraspinatus muscle atrophy in each and every patient. Second, is to find how much approximate change one can expect depending on age and tendon retraction

Read the detailed description

Retrospective review of 209 patients having both preoperative and immediate postoperative MRI done. Both preoperative and immediate postoperative occupancy ratio calculated and from that change in occupancy ratio calculated for each and every patient. Patient were divided in two major group according to age that is <60 years and >60 years and 3 subgroups of mild, moderate and severe depending on preoperative supraspinatus tendon retraction on coronal view of MRI. Postoperative occupation ratio was compared with preoperative occupation ratio within the subgroups and change in occupation ratio was used for comparison between the subgroup. Change in occupation ratio was also used for comparison between 2 major groups

What participants receive

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

  • arthroscopic rotator cuff repairProcedure or surgery

    arthroscopic rotator cuff repair done in all patients to check whether, surgery itself changes the appearance of muscle atrophy in the supraspinatus in all patients irrespective of size of preoperative tendon retraction

Study groups in NCT02628457
Study groupRoleWhat they receive
Mild Subgrouppatients with supraspinatus tendon retracted upto medial 1/3rd of humerus head and arthroscopic rotator cuff repair done by single row.
Receives: Procedure: arthroscopic rotator cuff repair
Moderate Subgrouppatients with supraspinatus tendon retracted between medial 1/3rd of humerus head and glenoid,and arthroscopic rotator cuff repair done by single row.
Receives: Procedure: arthroscopic rotator cuff repair
Severe subgrouppatients with supraspinatus tendon retracted beyond glenoid and arthroscopic rotator cuff repair done by single row
Receives: Procedure: arthroscopic rotator cuff repair

What is being measured

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

  1. change in supraspinatus muscle atrophy

    Supraspinatus muscle atrophy was measured and evaluated according to the Thomazeau classification. Stage 1: slight atrophy occupation ratio (1.00-0.60), Stage 2: moderate atrophy occupation ratio (0.60-0.40), Stage 3: Severe atrophy occupation ratio(<0.40). Both preoperative and immediate postoperative occupancy ratio calculated and from that change in occupancy ratio calculated for each and every patient.Postoperative occupation ratio was compared with preoperative occupation ratio within the groups and change in occupation ratio was used for comparison between the groups.

    Measured: within 1 week after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Rotator Cuff Tear, run by CM Chungmu Hospital at 1 site 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 3 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 11 Dec 2015. 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 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?

Results are not available in the source record.

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?

change in supraspinatus muscle atrophy (time frame: within 1 week after surgery). 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 11 Dec 2015.
