Study Overview
Brief Summary
The investigators evaluated the correlation between cutting-through at the greater tuberosity (GT) just medial to the lateral knotless anchor in arthroscopic suture-bridge rotator cuff repair and the bone mineral density (BMD) of the lumbar spine, hip and GT of the proximal humerus and to evaluate factors and clinical outcomes related to cutting-through at the GT.
Detailed Description
Seventy-eight patients who underwent arthroscopic suture-bridge rotator cuff repair and who had undergone dual energy X-ray absorptiometry (DEXA) scans before surgery were included. Patients were divided into two groups: patients who had cutting-through (46, group I) and patients who did not (32, group II). Clinical and radiological data including demographics, BMDs, fatty infiltration of rotator cuff muscles, tear size, tear involvement, VAS pain score, and ASES score were analyzed.

Outcomes
Primary Outcomes
Hip bone mineral density
Time Frame: preoperatively
Measured by using standard techniques according to the manufacturer and the International Society for Clinical Densitometry guidelines.
Visual Analog Scale (VAS) Pain Score
Time Frame: 2 years after surgery
The VAS pain score was based on a scale from 0 to 10, where 0 indicated no pain and 10 indicated severe pain
American Shoulder and Elbow Surgeons (ASES) score
Time Frame: 2 years after surgery
American Shoulder and Elbow Surgeons score for estimating shoulder function was based on a score from 0 to 100, where 0 indicated poor outcome and 100 indicated excellent outcome.
The occurrence of cutting-through
Time Frame: During the surgery
The occurrence of cortical breakage of the GT just medial to the lateral knotless anchor hole due to the tension of the sutures from the medial anchor
Greater tuberosity bone mineral density
Time Frame: preoperatively
GT BMD was measured using the predefined region of interest (ROI). Dividing the humeral head into three columns of even width, we defined a 1x1-cm2-sized square in the center of the lateral column as ROI.
Lumbar spine bone mineral density
Time Frame: preoperatively
Measured by using standard techniques according to the manufacturer and the International Society for Clinical Densitometry guidelines.
