Partial Superior Capsular Reconstruction to Augment Arthroscopic Repair of Massive Rotator Cuff Tears Using Autogenous Biceps Tendon: Effect on Retear Rate

Long head of biceps tendon autograft is effective in the management of large to massive rotator cuff tear: a systematic review

PURPOSE

The aim of this systematic review is to review the functional, clinical and radiological outcomes of patients undergoing large to massive rotator cuff repair with long head of biceps tendon (LHBT) autograft, as well as compare these to standard arthroscopic cuff repair.

METHODS

A review of the online Medline database was conducted on 20 October 2022 according to PRISMA guidelines and registered prospectively on the PROSPERO database. Clinical studies assessing patients with large to massive rotator cuff tears undergoing LHBT autograft repair were included. All studies reported on functional outcomes, range of movement (ROM) and radiological re-tear rates. The Methodological Index for Non-Randomised Studies (MINORS) tool was used to appraise all studies.

RESULTS

The search strategy identified ten studies for inclusion including a total of 594 patients. Five studies were comparable (346 patients), assessing LHBT autograft repair against arthroscopic rotator cuff repair without autograft. A variety of techniques of LHBT autograft were used across all studies, including bridging and augmentation styles. Radiographic comparison showed lower re-tear rates in the LHBT autograft group with two studies demonstrating statistically significant results. Pain scores, functional outcomes and ROM were significantly improved post-operatively in all studies for LHBT autograft patients, with no significant difference when compared to standard arthroscopic repair.

CONCLUSION

LHBT autograft looks to significantly improve functional scoring and range of motion in patients with large to massive rotator cuff tears. When compared to standard arthroscopic cuff repair, LHBT autograft appears to significantly reduce the re-tear rate. Further randomised studies are needed to assess the efficacy of this technique.

Comparison of Multiple Surgical Treatments for Massive Irreparable Rotator Cuff Tears in Patients Younger Than 70 Years of Age: A Systematic Review and Network Meta-analysis

BACKGROUND

Massive irreparable rotator cuff tears (MIRCTs) remain a challenging treatment paradigm, particularly for nonelderly patients without pseudoparalysis or arthritis.

PURPOSE

To use a network meta-analysis to analyze comparative studies of surgical treatment options for MIRCTs in patients <70 years of age for several patient-reported outcomes, range of motion (ROM), and acromiohumeral distance (AHD).

STUDY DESIGN

Network meta-analysis of comparative studies; Level of evidence, 3.

METHODS

A systematic review of the literature, using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, of the MEDLINE, Embase, and Cochrane Library databases was conducted from 2017 to 2022. Inclusion criteria were (1) clinical comparative studies of MIRCTs (with several study-specific criteria); (2) ≥1 outcome of interest reported on, with standard deviations; (3) minimum 1-year follow-up; and (4) mean age of <70 years for both cohorts, without arthritis or pseudoparalysis. There were 8 treatment arms compared. Outcomes of interest were the American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score, visual analog scale for pain, AHD, and forward flexion and external rotation ROM. A frequentist approach to network meta-analysis with a random-effects model was performed using the netmeta package Version 0.9-6 in R.

RESULTS

A total of 23 studies met the inclusion criteria, with 1178 patients included in the network meta-analysis. There was a mean weighted age of 62.8 years, 568 (48.2%) men, with a mean follow-up of 28.9 months. There were no significant differences between groups in regard to sex (P = .732) or age (P = .469). For the ASES score, InSpace balloon arthroplasty (mean difference [MD], 12.34; 95% CI, 2.18 to 22.50; P = .017), arthroscopic bridging graft (aBG) (MD, 7.07; 95% CI, 0.28 to 13.85; P = .041), and long head of biceps augmented superior capsular reconstruction (BSCR) (MD, 5.16; 95% CI, 1.10 to 9.22; P = .013) resulted in the highest P-scores. For the Constant-Murley score, debridement (MD, 21.03; 95% CI, 8.98 to 33.08; P < .001) and aBG (MD, 6.97; 95% CI, 1.88 to 12.05; P = .007) resulted in the highest P-scores. For AHD, BSCR resulted in the highest P-score (MD, 1.46; 95% CI, 0.45 to 2.48; P = .005). For forward flexion ROM, debridement (MD, 45.77; 95% CI, 25.41 to 66.13; P < .001) resulted in the highest P-score, while RSA resulted in the lowest P-score (MD, -16.70; 95% CI, -31.20 to -2.20; P = .024).

CONCLUSION

For patients <70 years with MIRCT without significant arthritis or pseudoparalysis, it appears that graft interposition repair techniques, superior capsular reconstruction using the long head of the biceps tendon, arthroscopic debridement, and balloon arthroplasty provide superiority in various outcome domains, while RSA provides the least benefit in forward flexion.

Clinical Outcomes and Re-Tear Rates for Partial Arthroscopic Rotator Cuff Repair With or Without Biceps Augmentation for Large-to-Massive Tears: A Systematic Review and Meta-analysis

BACKGROUND

The recent addition of biceps tendon augmentation to partial arthroscopic rotator cuff repair (ARCR) for the treatment of large-to-massive rotator cuff tears is proposed to improve clinical outcomes and reduce re-tears.

MATERIALS AND METHODS

The purpose of this systematic review and meta-analysis (5 studies) was to compare outcomes between partial ARCR with (142 patients) and without (149 patients) biceps augmentation.

RESULTS

Partial ARCR with and without biceps augmentation were comparable in pain, function, and range of motion. However, biceps augmentation vs no augmentation at all during ARCR may lower re-tear rates for irreparable large-to-massive rotator cuff tears (42.9% vs 72.5%, P=.007).

CONCLUSION

More research is needed to investigate this technique and guide surgical decision-making. [Orthopedics. 2024;47(5):e217-e224.].

Reduced retear rates yet similar clinical outcomes following arthroscopic partial repair of large and massive irreparable rotator cuff tears with biceps augmentation compared to repairs without biceps augmentation: A systematic review and meta-analysis

PURPOSE

To compare the clinical outcomes between arthroscopic partial rotator cuff repair with biceps augmentation (BA) and partial repair (PR) without BA.

METHODS

This systematic review included studies comparing outcomes of arthroscopic repair for large to massive irreparable rotator cuff tears with and without the BA. The focus was on postoperative clinical results and retear rates. Mean differences were used to express continuous outcomes, while odds ratios (ORs) were employed for dichotomous outcomes.

RESULTS

Ten studies (733 shoulders, all level 3 evidence) were included. The BA group showed a significant reduction in retear rates (OR = 0.40, 95% confidence interval [CI]: 0.20-0.77, P = 0.007) and comparable postoperative outcomes across various measures: American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale for pain, University of California-Los Angeles shoulder score, active forward flexion motion and active external rotation at the arm-at-side position compared to the PR group. Subgroup analysis of two BA techniques-rerouting and supplementation following supraglenoid tenotomy-showed no significant differences in ASES score for either technique versus PR. However, rerouting significantly lowered retear rates (OR = 0.21, 95% CI: 0.12-0.36, p < 0.001), while supplementation showed similar retear rates to PR (OR = 0.87, 95% CI: 0.37-2.02, n.s.).

CONCLUSION

Arthroscopic partial rotator cuff repair with BA for large to massive irreparable rotator cuff tears is a reliable technique, resulting in improved postoperative outcomes. BA using supplementation following supraglenoid tenotomy showed similar clinical outcomes and range of motion but with lower retear rates compared to the PR group.

Long head of biceps tendon augmentation for massive rotator cuff tears improves clinical results regardless of the number of tendons involved

PURPOSE

Management of massive rotator cuff tears (MRCTs) remains debated, and various arthroscopic and open techniques have been described for their management. Nevertheless, the optimal strategy remains unclear. The present study evaluated the clinical results in patients managed arthroscopically for MRCTs augmented with the long head biceps tendon (LHBT) at a minimum 1-year follow-up, considering different type of tears, demographic data and number of torn tendons.

METHODS

Patients treated in a secondary referral centre from January 2021 to April 2022 were enroled prospectively. Inclusion criteria were pain, inability to fully elevate the affected shoulder, irreparable tears and active and motivated patients. All patients were managed within 2 months from diagnosis in a single centre by the same surgeons. Preoperative shoulder radiographs and magnetic resonance imaging (MRI) were collected, and clinical assessment was also performed using the Numerical analogue scale (NAS), Constant score (CS) American Shoulder and Elbow Surgeons Shoulder Score (ASES). Tissue retraction and tendon fatty infiltration were evaluated using Patte and Fuchs scale, respectively. Clinical assessment was performed using the same scales at 3-6 months and 1-year follow-up.

RESULTS

A total of 55 patients (31 female and 24 male) with a mean age of 60 ± 7.1 years were enroled for a mean follow-up of 18.2 ± 4.3 months. The mean preoperative NAS was 7.8 ± 0.6, CS was 20.5 ± 7.6 and ASES was 22.6 ± 9.2, increasing, respectively, to 0.3 ± 0.6, 91.5 ± 6.9 and 94.2 ± 6.7. No adverse side effects (infection, rejection, allergy) were reported during the study period. All patients were evaluated after surgery at 3 and 6 months and 1 year with statistically significant improvement for each score at the first and last follow-up (p < 0.05).

CONCLUSIONS

The use of LHBT augmentation in patients with MRCTs in appropriately selected patients is safe and effective and can lead to pain relief and acceptable clinical outcomes. Furthermore, its use carries low donor site morbidity and is cost effective. Comparative studies, including randomised controlled trials, with other proposed techniques are needed to confirm these findings.

Clinical outcomes of arthroscopic superior capsule reconstruction in patients aged over 70 with irreparable rotator cuff tears

Background

Arthroscopic superior capsule reconstruction (SCR) was developed to restore superior shoulder stability, muscle balance, and function after irreparable posterior-superior rotator cuff tears. The purpose of this study was to investigate whether favorable clinical outcomes after SCR for irreparable rotator cuff tears would be obtained in patients aged more than 70 years.

Methods

A total of 173 consecutive shoulders in 162 patients who underwent arthroscopic SCR using autografts of fascia lata for irreparable rotator cuff tears were allocated to 3 groups according to patient age at the time of surgery: Group 1, <55 years old (11 shoulders); Group 2, 55-70 years old (85 shoulders); and Group 3, > 70 years old (77 shoulders). American Shoulder and Elbow Surgeons and Japanese Orthopaedic Association scores, active shoulder range of motion, and visual analog scale were evaluated before surgery and at the final follow-up. Postoperative complications, including graft tears in magnetic resonance imaging and donor-site morbidity, were assessed.

Results

The mean follow-up was 3 years and 9 months. Both American Shoulder and Elbow Surgeons and Japanese Orthopaedic Association scores and active range of motion (elevation, external rotation, and internal rotation) increased significantly after arthroscopic SCR in all 3 groups (P < .001), and visual analog scale decreased significantly. All 3 groups had low graft tear (6%-10%) and donor site morbidity (0%-1%) rates, with no significant difference among the groups.

Conclusion

Arthroscopic SCR can lead to functional improvement and pain relief with a low rate of complications regardless of patient age.

Outcomes of Superior Capsular Reconstruction Using the Long Head of the Biceps Tendon in Large to Massive Rotator Cuff Tears: A Meta-Analysis and Systematic Review

(1) Background: Addressing large to massive rotator cuff tears (LMRCTs) poses complex challenges. This systematic review investigated outcomes of superior capsular reconstruction (SCR) with the long head of the biceps tendon (LHBT) compared to conventional rotator cuff repair (RCR) for LMRCTs. (2) Methods: A systematic search across the MEDLINE/PubMed, EMBASE, Cochrane Library, and Scopus databases until 1 October 2023 identified studies that directly compared SCR with LHBT with conventional RCR in patients with LMRCTs and included a minimum of a 12-month follow-up period. The assessed outcome measures encompassed retear rates, functional outcomes, range of motion (ROM), and acromiohumeral interval (AHI). Risk of bias assessment was conducted via the Robins-I tool. (3) Results: In six studies with 456 cases (210 SCR using LHBT and 246 using RCR), SCR with LHBT significantly reduced retear rates (OR = 0.21; 95% CI, 0.12-0.36; p < 0.01; I2 = 0%). Furthermore, SCR with LHBT showed significant improvement in range of forward flexion (SMD 0.32, 95% CI: 0.09-0.55, p < 0.01, I2 = 39%) and AHI (SMD 0.61, 95% CI: 0.31-0.92, p < 0.01, I2 = 0%) postoperatively. (4) Conclusion: SCR with LHBT is a safe and effective treatment for LMRCTs, reducing retear rates, maintaining greater postoperative AHI, and improving ROM compared to conventional RCR. Additional high-quality interventional studies are needed to confirm these results.

Arthroscopic superior capsule reconstruction augmentation using a semitendinosus autograft in massive reparable rotator cuff tears

Background

Arthroscopic superior capsule reconstruction (SCR) augmentation is a viable treatment option for massive reparable cuff tears. This study aimed to retrospectively compare clinical and imaging outcomes of patients with reparable massive rotator cuff tears after arthroscopic rotator cuff repair (ARCR) with those after SCR augmentation using a semitendinosus autograft.

Methods

We retrospectively compared 50 patients with massive reparable rotator cuff tears who underwent ARCR and SCR augmentation (n = 25 each). Patients were clinically followed up for at least 2 years, and the American Shoulder and Elbow index, other patient-reported outcomes, active range of motion, and radiography and magnetic resonance imaging findings were assessed.

Results

At the final follow-up, both patient groups showed significant improvements in forward elevation in range of motion and visual analog scale scores. Improvements in the American Shoulder and Elbow scores in the SCR augmentation group were significantly superior to those in the ARCR group (48.3 and 28.9, P < .01). There was a significant difference in the retear rate between the SCR augmentation group and ARCR group (20% and 56%, respectively; P = .009).

Conclusion

Our study demonstrated that patient-reported outcomes and retear rates in patients who underwent SCR augmentation with rotator cuff repair for massive rotator cuff tears significantly improved compared with those in patients who underwent ARCR without augmentation. Augmentation with semitendinosus autografting during rotator cuff repair represents a solution for patients with massive reparable rotator cuff tears.

The long head of the biceps tendon: a valuable tool in shoulder surgery

ANATOMY AND FUNCTION

The long head of the biceps tendon (LHBT) has different properties and characteristics that render it a valuable tool in the hands of shoulder surgeons. Its accessibility, biomechanical strength, regenerative capabilities, and biocompatibility allow it to be a valuable autologous graft for repairing and augmenting ligamentous and muscular structures in the glenohumeral joint.

SHOULDER SURGERY APPLICATIONS

Numerous applications of the LHBT have been described in the shoulder surgery literature, including augmentation of posterior-superior rotator cuff repair, augmentation of subscapularis peel repair, dynamic anterior stabilization, anterior capsule reconstruction, post-stroke stabilization, and superior capsular reconstruction. Some of these applications have been described meticulously in technical notes and case reports, whereas others may require additional research to confirm clinical benefit and efficacy.

CONCLUSION

This review examines the role of the LHBT as a source of local autograft, with biological and biomechanical properties, in aiding outcomes of complex primary and revision shoulder surgery procedures.

Effect of Anterior Acromial Coverage on Functional and Radiological Outcomes After Arthroscopic Repair of Anteroposterior Massive Rotator Cuff Tears

BACKGROUND

Rotator cuff tear size, fatty infiltration, and scapular morphology are correlated with tendon healing and functional outcomes after arthroscopic repair; however, the association between anteroposterior acromial coverage and the clinical outcomes of anteroposterior massive rotator cuff tears (AP-MRCTs; involving all 3 tendons) remains unclear.

PURPOSE

To identify the association between AP acromial coverage and functional and radiological outcomes after arthroscopic repair of AP-MRCTs.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

A total of 98 patients who underwent arthroscopic repair of AP-MRCTs between January 2015 and December 2020 were included in the study and classified according to whether anterior acromial coverage (AAC) was anterior (46 patients; positive AAC group) or posterior (52 patients; negative AAC group) to the scapular line on true lateral shoulder radiographs. Demographic characteristics, surgical details, and functional outcomes were prospectively collected. Acromial morphological features, global tear extension (GTE), the global fatty infiltration index (GFII), tendon integrity after repair, proximal humeral migration, and glenohumeral abduction were measured and calculated on radiographs or magnetic resonance imaging scans preoperatively and at 2 years postoperatively. Multivariate logistic regression was performed to identify the independent risk factors of a rotator cuff retear.

RESULTS

The positive AAC group showed larger AAC, posterior acromial tilt, and anterior acromial slope as well as smaller posterior acromial coverage compared with the negative AAC group. Postoperatively, the American Shoulder and Elbow Surgeons score (82.5 ± 8.3 vs 77.2 ± 11.5, respectively; P = .013), active abduction (157.8°± 27.1° vs 142.7°± 39.6°, respectively; P = .048), and glenohumeral abduction (45.6°± 10.4° vs 39.7°± 14.9°, respectively; P = .041) in the positive AAC group were significantly higher than those in the negative AAC group, while the retear rate (23.9% vs 44.2%, respectively; P = .035) and proximal humeral migration (1.7 ± 1.0 vs 2.3 ± 1.2 mm, respectively; P = .006) were significantly lower in the positive AAC group than in the negative AAC group. Smaller AAC (odds ratio [OR], 0.93 [95% CI, 0.87-1.00]; P = .040), larger GTE (OR, 1.03 [95% CI, 1.01-1.06]; P = .017), and a higher GFII (OR, 3.49 [95% CI, 1.09-11.19]; P = .036) were associated with an increased risk of a rotator cuff retear.

CONCLUSION

Increased AAC was associated with a lower retear rate and better functional outcomes after arthroscopic repair of AP-MRCTs. A preliminary risk evaluation integrating GTE, the GFII, and AAC is recommended to consider the necessity of additional procedures for patients in need of arthroscopic rotator cuff repair.

Arthroscopic Superior Capsular Reconstruction With the Long Head of the Biceps Tendon to Reinforce the Repair of a Supraspinatus Tear and Increase Healing

Rotator cuff tears continue to be a challenge for the shoulder surgeon since there is still a high rate of retears. To increase the rate of repair and decrease the number of retears, we present a technique, in which we reinforce a tension-free double-row repair of the supraspinatus with reconstruction of the superior capsule with the long head of the biceps (LHB). With this reinforcement of the cuff suture using the LHB, we increase both the biomechanics and biology of the repair and decrease the rate of reruptures.

Editorial Commentary: Superior Capsular Reconstructions in Cases of Irreparable Rotator Cuff Tendons Only Partially Restore Anatomy, Yet Significantly Normalize Biomechanics-Without Resorting to Reverse Anatomy

The goal of shoulder superior capsular reconstruction and/or anterior cable reconstructions, at least in terms of biomechanics, is to primarily restore a fulcrum to assist with pain control and functional optimization, with the secondary hope of maintaining cartilage. Fully restoring glenohumeral joint loads with SCR cannot be expected in the setting of persistent tendon insufficiency. Biomechanical studies characterizing shoulder capsular reconstructions have demonstrated anatomic and functional restorations toward normalization when tested with standard biomechanical methods. Glenohumeral abduction, superior humeral head migration, deltoid forces, and glenohumeral contact pressure and area, can be optimized toward the normal intact condition, as measured by motion tracking and pressure mapping in real time, using dynamic actuators. Insofar as restoring normal native anatomy is considered a fundamental priority, with the idea that joint functional longevity is enhanced by preserving anatomy, as surgeons, we should not lose sight of reconstruction over replacement (such as nonanatomic reverse total shoulder arthroplasty) as a favored goal. Anatomy-based reconstructions such as superior capsule or anterior cable reconstruction, may prove over time to be the best primary treatment as knowledge and innovations (technical and medical) develop, with nonanatomic arthroplasty truly being a last resort (yet a clinically viable option when indicated).

The use of long head biceps tendon autograft for massive rotator cuff tears: a PRISMA compliant systematic review

INTRODUCTION

Rotator cuff tears (RCT) are a common cause of shoulder pain and disability, with massive RCT accounting for 10-40% of all rotator cuff tears.

SOURCES OF DATA

A systematic search of PubMed and Scopus electronic databases was performed up to August 2022, and a total of 17 scientific articles were included in the present PRISMA compliant systematic review.

AREAS OF AGREEMENT

Understanding the geometric patterns in RCT is essential to achieve appropriate repositioning of the injured tendons in their anatomic location. The long head of the biceps tendon (LHBT) is usually exposed when defects of the anterolateral corner are present and can be easily used to augment rotator cuff repairs.

AREAS OF CONTROVERSY

There are no definite guideline regarding the management of massive rotator cuff tears.

GROWING POINTS

The use of LHBT graft is safe and effective, but technically demanding. All studies were level IV articles of medium to high quality.

AREAS TIMELY FOR DEVELOPING RESEARCH

Prospective long term follow-up studies and randomized controlled trials are needed, adding imaging evaluation and appropriate clinical outcome measures at follow-up.
