Abstract

Introduction

The purpose of this study is to compare the clinical outcomes according to preoperative external rotation (ER) status, comparing patients with a preoperative ER lag sign (ERL group) to those with preoperative no ER lag sign (non-ERL group) in arthroscopy-assisted lower trapezius tendon transfer (aLTT) for posterosuperior rotator cuff tears (PSIRCTs).

Methods

This retrospective study reviewed 107 patients who were treated with aLTT for PSIRCTs between 2017 and 2022. The patients were divided into ERL group (n = 20) and non-ERL group (n = 87). Clinical outcomes were evaluated with shoulder pain, patients-reported clinical scores, active range of motion (aROM) and strength of aROM. Radiologic outcomes were evaluated with acromiohumeral distance and Hamada classification. The relationship between trophicity of teres minor (Tm) and clinical outcomes was evaluated.

Results

Preoperative patients-reported clinical scores, aROM, and strength of aROM were significantly lower in ERL group. Although a significant improvement of postoperative pain score, patients-reported clinical scores, aROM, and strength of aROM was observed in both groups, these postoperative outcomes were significantly lower in ERL group. However, the mean improvement of Constant score, University of California, Los Angeles (UCLA) score, and activities of daily living that require active external rotation (ADLER) score, forward elevation (FE), abduction, external rotation (ER) were significantly higher in ERL group than that of non-ERL group. Moreover, there was a significant correlation between Tm trophicity and postoperative Constant, UCLA, American Shoulder and Elbow Surgeons score, ADLER, FE and ER.

Conclusion

aLTT can be a reliable treatment option and should be considered as primary joint-preserving treatment option for patients with PSIRCTs regardless of preoperative ER lag sign.

Level of study

Level IV.

期刊介绍： Journal of Orthopaedics aims to be a leading journal in orthopaedics and contribute towards the improvement of quality of orthopedic health care. The journal publishes original research work and review articles related to different aspects of orthopaedics including Arthroplasty, Arthroscopy, Sports Medicine, Trauma, Spine and Spinal deformities, Pediatric orthopaedics, limb reconstruction procedures, hand surgery, and orthopaedic oncology. It also publishes articles on continuing education, health-related information, case reports and letters to the editor. It is requested to note that the journal has an international readership and all submissions should be aimed at specifying something about the setting in which the work was conducted. Authors must also provide any specific reasons for the research and also provide an elaborate description of the results.
