Abstract
Rotator cuff repair was traditionally included SAD as an essential step to widen the subacromial space and relieve impingement symptoms following the extrinsic theory for the development of rotator cuff tear.
Many pathologic researches supported that rotator cuff is due to intrinsic defect in the tendon itself and not due to extrinsic compression. These studies made a great dought as regard the indications and the effectiveness of SAD in the treatment of rotator cuff tears.
Recent clinical researches provided satisfactory outcomes for arthroscopic rotator cuff repair without SAD which added more dought upon the need for decompression.
In our study we evaluated the clinical outcomes of arthroscopic rotator cuff repair without SAD and we tried to provide an objective explanation for patients improvement, which is, restoration of rotator cuff function can restore the height of SAS due to restoration of muscle balance around the shoulder joint.
Finding an accurate method to measure the SAS height was another issue in our work. We used a new 3D technique to detect the changes in SAS height.
Arthroscopic rotator cuff repair without SAD is a simple and time saving alternative for repair with SAD. It can provide satisfactory outcomes as regard pain relief, improving function and range of motion. Also it avoids the complications that can follow SAD and preserves tissues necessary for healing.
This procedure can lead to improvement in SAS narrowing and impingement symptoms without the need for additional SAD.
