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.
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.
