Comparison of arthroscopic-assisted mini open and all arthroscopic repair methods in small to large size rotator cuff tears

Aim: This study aimed to compare the functional and clinical results of all arthroscopic (AA) and arthroscopic-assisted mini open (AAMO) rotator cuff tear (RCT) repair methods with a minimum 2 years follow-up. Methods: In this retrospective study, patients who operated with the AA repair method were included in group 1 and patients who operated with AAMO RCT repair method were included in group 2. Between January 2018 and June 2021. All patients were evaluated with shoulder range of motion (ROM), the Disabilities of the Arm, Shoulder and Hand (DASH), Constant Murley Score (CMS) and visual analog scale (VAS) pain score preoperatively and postoperatively. Postoperative evaluation was made on the 3rd, 6th, 12th, and 24th months. In addition, the length of hospital stay, and surgery time were evaluated. Results: Eighty patients (48 female, 32 male) were included in group 1, who were treated with the AA technique. Sixty-seven patients (28 male, 39 female) were included in group 2, who were treated with the AAMO technique. The average follow-up time was 29,36 ±3,48 months for group 1, 28,12±2,87 months for group 2. No significant difference was detected between group 1 and group 2 for length of hospital stay and follow-up time (p>0,05). At the postoperative 3rd-month follow-up measurements, a statistically significant difference was determined between group 1 and group 2 for abduction, flexion measurements, VAS score, and DASH score (p=0,03, p=0,04, p=0,02, p=0,01 respectively). At the 24th month postoperative follow-up, statistically no significant difference was determined between groups 1 and 2 in terms of ROM, VAS, and functional scores. Conclusion: In the early recovery period, AA repair provides better ROM, DASH, and VAS scores. However, in long-term follow-up, no significant difference was detected in AA and AAMO repair in terms of functional results, ROM, and VAS scores.
