Middle Trapezius Tendon Transfer for Augmentation of In Situ Superior Capsular Reconstruction-Reinforced Partial Rotator Cuff Repair: Short-term Outcomes of a Prospective Cohort Study

Background

Middle trapezius tendon (MTT) transfer has been described for dynamic reproduction of supraspinatus function. For management of irreparable rotator cuff (RC) tears, this procedure can be coupled with in situ (long head of the biceps tendon-based) superior capsular reconstruction (SCR) and partial RC repair.

Purpose

To investigate the functional outcomes of augmentation of in situ SCR-reinforced partial RC repair with MTT transfer for the management of irreparable posterosuperior RC tears.

Study Design

Cohort study; Level of evidence, 3.

Methods

Conducted between September 2014 and March 2022, this study included 24 patients with irreparable posterosuperior RC tears who were allocated into 2 groups: patients managed with 2-layer tendon construct (in situ SCR-reinforced partial RC repair) (group A; n = 15) and patients managed with 3-layer tendon construct (MTT transfer-augmented, in situ SCR-reinforced partial RC repair) (group B; n = 9). Outcome measures included 2-year postoperative pain, range of motion (ROM) in forward flexion and external rotation, and the American Shoulder and Elbow Surgeons (ASES) and the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores. For data comparison, independent and paired t tests were used for parametric quantitative variables, and Mann-Whitney and Wilcoxon signed-rank tests were used for nonparametric quantitative variables; Fisher exact and McNemar tests were used for qualitative variables.

Results

The mean age of the patients was 58.40 ± 4.54 years in group A and 59.22 ± 4.46 years in group B; there were no between-group differences in baseline patient characteristics. Patients in both groups had significant preoperative to postoperative improvement on all outcome measures (P < .05 for all). Group B had a significantly higher magnitude of postoperative improvement compared with group A in forward flexion ROM (88.88° ± 29.34° vs 46.66° ± 20.93°; P = .001), external rotation ROM (32.22° ± 14.81° vs 16.0° ± 9.10°; P = .002), ASES score (71.07 ± 8.26 vs 57.87 ± 8.39; P = .001), and QuickDASH score (-70.20 ± 6.95 vs -58.34 ± 12.52; P = .007).

Conclusion

Augmentation of in situ SCR-reinforced partial RC repair with MTT transfer in a 3-layer tendon construct led to significantly greater improvement in postoperative ROM and functional scores compared with a 2-layer construct.

Rotator cuff repair with or without proximal end detachment for long head of the biceps tendon tenodesis

Background

Rotator cuff tears cause pathologies of the long head of the biceps tendon (LHBT). One of the surgical treatments for such a tear is LHBT tenodesis to the humerus. This study aims to compare simultaneous rotator cuff repair and LHBT tenodesis with or without detachment of the proximal end of the LHBT (PELHBT) from its site of adhesion to the glenoid.

Methods

This retrospective study involved patients affected by LHBT pathology with rotator cuff tear. The patients were divided into two groups, with or without PELHBT detachment from the glenoid. Therapeutic outcomes were investigated by evaluation of patient satisfaction, pain based on visual analog scale, shoulder function based on Constant score and simple shoulder test, and biceps muscle strength based on the manual muscle testing grading system before surgery, at 6 months, and at the final visit after surgery.

Results

Groups 1 and 2 comprised 23 and 26 patients, respectively, who showed no significant differences in demographic characteristics (p>0.05). Shoulder function, biceps muscle strength, pain, and satisfaction rate improved over time (p<0.05) but were not significantly different between the two groups (p>0.05). No post-surgical complication was found in either group.

Conclusions

There was no difference in final outcomes of tenodesis with or without detachment of the PELHBT from the supraglenoid tubercle. Such tendon detachment is not necessary.
