Comparison of Long-term Supraspinatus Tear Progression After Arthroscopic Isolated Subscapularis Repair With and Without Comma Tissue Preservation: A Minimum 10-Year MRI Follow-up Study

This study investigates whether preserving the comma tissue during arthroscopic isolated subscapularis repair offers long-term advantages over the margin disruption technique, particularly concerning supraspinatus tear progression and clinical outcomes over a minimum of 10 years. The findings reveal that the in-continuity technique is associated with a significantly lower incidence of supraspinatus tears and better clinical outcomes compared to the margin disruption technique. The authors conclude that preserving comma tissue may enhance long-term shoulder function and reduce the risk of complications.
