Rotator Cuff Tear

Keywords
occupation ratio, pseudoatrophy
Brief 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
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
Interventions
PROCEDUREarthroscopic rotator cuff repair
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

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.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| change in supraspinatus muscle atrophy | within 1 week after surgery | 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. |
