Background:

Given the growing concerns regarding objective measures of clinical outcomes, attention has recently been devoted to the establishment of clinically significant outcome (CSO) thresholds for patient-reported functional scores after rotator cuff surgery.

Purpose:

To retrospectively compare patient-reported outcome (PRO) measures (PROMs) and radiographic data between patients who underwent arthroscopic superior capsular reconstruction (SCR) with and without long head of the biceps tendon (LHBT) augmentation.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A total of 43 patients receiving arthroscopic SCR between 2016 and 2020 were enrolled, including a biceps augmentation group (n = 27) and a nonaugmentation group (n = 16). Patients were asked an anchor question regarding their satisfaction and perception of improvements. PROMs of American Shoulder and Elbow Surgeons (ASES), Constant score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) for pain scores and radiographic data including magnetic resonance imaging and plain radiographs were collected and compared between the 2 groups. Anchor questions in CSO analysis for deriving the minimal clinically importance difference (MCID), substantial clinical benefit (SCB), Patient Acceptable Symptom State (PASS), and maximal outcome improvement (MOI) values were applied ≥2 years postoperatively.

Results:

Based on satisfaction responses, 17 patients were classified as satisfied, 16 as unsatisfied, and 10 as fair. Additionally, 13 patients felt they were improved, 14 changed, and 16 unchanged. Intergroup comparison based on patients’ satisfaction and perception of change or improvement exhibited significant differences in all 4 functional scores in favor of the satisfied and improved patients. However, there was no significant difference in the ΔVAS scores between the groups. CSO analyses showed no significant difference in percentage of patients achieving MCID, SCB, and PASS thresholds for the ΔASES, ΔConstant, and ΔSANE scores between patients undergoing arthroscopic SCR with or without LHBT augmentation. A significant difference was found in the percentage of patients achieving the MOI for ΔASES score with 70.4% in the augmented group and 37.5% in the nonaugmented group, respectively. The mean acromiohumeral distance (AHD) differed significantly between augmentation (8.1 ± 2.2 mm) and nonaugmentation (7 ± 1.9 mm) groups. The graft tear rate did not differ significantly.

Conclusion:

There was no significant difference in PROs and percentage of patients achieving MCID, SCB, and PASS between isolated and augmented SCR groups. A higher percentage of patients achieving MOI and slightly greater AHD were found in the augmented group. Further evaluation is required to determine if there is any long-term benefit to LHBT augmentation of SCR.
