Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Mild Subgroup

patients with supraspinatus tendon retracted upto medial 1/3rd of humerus head and arthroscopic rotator cuff repair done by single row.

arthroscopic rotator cuff repair

Intervention Type PROCEDURE

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

Moderate Subgroup

patients with supraspinatus tendon retracted between medial 1/3rd of humerus head and glenoid,and arthroscopic rotator cuff repair done by single row.

Severe subgroup

patients with supraspinatus tendon retracted beyond glenoid and arthroscopic rotator cuff repair done by single row

Intervention Type PROCEDURE

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Patients with degenerative rotator cuff tear who underwent single-row arthroscopic rotator cuff repair in our hospital.
2. Patients with preoperative MRI and postoperative MRI within 1 week of surgery in our hospital.
3. Patients with minimum grade 1 supraspinatus atrophy in preoperative MRI.

Exclusion Criteria

1. Patients with preoperative MRI from outside hospital.
2. Patients with isolated subscapularis tear.
3. Patients with previous operation on the same shoulder joint.
4. Patients with MRI images that were not usable due to poor quality or absence of appropriate Y-view.
