Higher Critical Shoulder Angle has an Increased Risk of Re-Tear After Arthroscopic Rotator Cuff Repair At Long Term Follow-Up

Aim
The purpose of this study was to examine the effect of critical shoulder angle (CSA), acromion index (AI), and glenoid inclination (GI) on functional outcomes and tendon integrity at a minimum follow-up of 10 years.
Background
Recently, a few studies investigated the relation between scapular anatomy variations and clinical outcomes after arthroscopic rotator cuff (RC) repair. However, there is a lack of research investigating the influence of distinct anatomic variants of scapula on clinical outcomes and healing rates at long term follow-up.
Methods
A total of 44 patients (with a mean of age at surgery 52.1±9.9 years) who underwent arthroscopic double row knotless repair of full-thickness rotator cuff tears by a single surgeon with a minimum follow-up of 10 years were included. Two independent reviewers measured the CSA, AI and GI on preoperative true anteroposterior radiographs and intraclass correlation …
