The results of using a tendon autograft as a new rotator cable for patients with a massive rotator cuff tear: a technical note and comparative outcome analysis

Content reporting and effectiveness of therapeutic exercise in the management of massive rotator cuff tears: A systematic review with 490 patients

Background

Massive rotator cuff tears (MRCT) account for a substantial fraction of tears above the age of 60 years. However, there are no clear criteria for prescription parameters within therapeutic exercise treatments. The aim of this study was to evaluate the effects and characteristics of therapeutic exercise treatments in patients with MRCT.

Methods

A systematic search was conducted in MEDLINE/PubMed, Web of Science, SPORTDiscus, SciELO, Scopus and EMBASE from inception to August 2022. Studies were included if they evaluated the effects of exercise on patients with MRCT. The risk of bias was evaluated and the Consensus on Exercise Reporting Template (CERT) was also used. A narrative synthesis without meta-analysis was performed.

Results

One randomized controlled trial, two non-randomized studies, six non-controlled studies, one case series and four retrospective studies were included. They ranged from serious to moderate risk of bias. The CERT reflected a poor description of the exercise programmes. Studies showed a pattern of improvements in most patient-reported outcome measures (PROM) surpassing the MCID, and active elevation range of motion.

Conclusions

There is limited evidence that exercise and co-interventions are effective in the management of some patients with MRCT, based on a systematic review without meta-analysis. Future research should improve content reporting.

Long Head of the Biceps Pediculated Autograft Augmentation of Arthroscopic Subscapularis Repair

Subscapularis (SSc) repairs are not free of failure and continues to pose a challenging problem. Although various biological and structural augmentation methods are available for the posterosuperior rotator cuff, few options have been explored for the anterior one. In the Technical Note, we describe an all-arthroscopic technique in which we use the long head of the biceps tendon (LHBT) as a pediculated autograft to reinforce an SSc repair. After SSc repair and LHBT tenodesis, the intra-articular portion of the LHBT is placed on the upper part of the SSc tendon at the rotator interval. Repurposing the otherwise-discarded tendon brings several biological and mechanical advantages at a lower cost without donor-site morbidity.

Rotator Cable Reconstruction: A Technique to Restore the Rotator Cable in the Setting of Large Cuff Tears

The rotator cable is an essential biomechanical structure in the shoulder that is commonly injured in the setting of large rotator cuff tears. Surgical techniques designed to reconstruct the cable have followed advancements in our understanding of the biomechanics and anatomic importance of this structure. Owing to its role in load sharing and stress shielding of the rotator cuff crescent, rotator cable reconstruction offers the potential to reduce retear rates and promote longevity of rotator cuff repairs. The purpose of this article is to describe a technique to augment rotator cuff repair with cable reconstruction.

Using Biceps Tendon Autograft as a Patch in the Treatment of Massive Irreparable Rotator Cuff Tears Improves Patient-reported Outcome Scores: A Systematic Review

Purpose

To review the clinical studies describing the use of ipsilateral biceps tendon autograft for bridging irreparable massive rotator cuff tears (MRCTs).

Methods

A systematic review was conducted of MEDLINE, Embase, Cochrane, CINAHL, and Scopus databases using search terms "massive rotator cuff tear," "irreparable rotator cuff tear," and "long head of the biceps tendon." Only clinical human studies in which the biceps tendon was used as a bridging graft in MRCTs were included. All review studies, technique papers, and studies describing the use of biceps tendon as superior capsular reconstruction equivalent or rotator cable were excluded.

Results

A total of 45 studies were initially identified, of which only 6 studies met the inclusion criterion. All studies were retrospective in nature, with a total of 176 patients. All studies reported a clinically significant improvement in postoperative functional outcomes, although this was not compared to a control group in all the studies. Pain was assessed using the visual analog scale (VAS) in 4 studies, and all reported an improvement in postoperative VAS ranging from 5 to 6 points. One study reported an improvement in pain scale from Japanese Orthopedic Association from 13.1 to 22.5 (9 points). One study did not report a VAS score as this study was published before the VAS score was developed. All the reported studies saw improvements in range of motion.

Conclusions

The use of the long head of the biceps tendon as an interposition/bridging patch to augment the MRCT repair can reduce the VAS score, improve elevation and external rotation, and improve clinical and functional outcomes.

Biceps Smash Technique: Biceps Tendon Autograft Augmentation for Arthroscopic Rotator Cuff Reconstruction

The proportion of postoperative retears after arthroscopic rotator cuff reconstruction remains constant despite advancement of suture techniques and improved anchor implants. The commonly degenerative nature of rotator cuff tears can carry the risk of compromised tissue. Several techniques have been developed to biologically enhance rotator cuff repair, and a considerable number of autologous, allogeneic, and xenogenous augmentation methods have been described. This article introduces the biceps smash technique, an arthroscopic augmentation procedure for posterosuperior rotator cuff reconstruction using an autograft patch of the long head of the biceps tendon.

Early Treatment of Shoulder Pathology Is Necessary but Not Enough Is Being Performed

Delayed treatment of shoulder instability results in bone loss requiring more-complicated surgery, in turn resulting in less-optimal outcomes. Similarly, delayed treatment of repairable rotator cuff tears results in irreparable tears requiring more-complicated surgery and resulting in less-optimal outcomes. Delayed treatment of shoulder pathology is a problem. Solutions include education and research investigation.

Compressed Biceps Autograft Augmentation of Arthroscopic Rotator Cuff Repair

Rotator cuff repair failure rates continue to be a challenging problem. Various methods of biological and structural augmentation of the rotator cuff have been explored to improve tendon healing after repair. We describe a technique in which biceps tendon autograft is harvested after tenodesis. The biceps tendon is then compressed into a patch that is placed over the repaired rotator cuff tendon. Repurposing the portion of the tendon that is otherwise discarded offers several advantages over other augmentations that have been used, including the biological potential of live autograft tenocytes in the patch, lower cost, and no donor-site morbidity.

Editorial Commentary: If the Massive Rotator Cuff Tear is Irreparable, Just Fix the Rotator Cable

Large and massive rotator cuff tears are not always reparable and present a difficult clinical problem. If surgery is warranted surgical options range from arthroscopic debridement, partial repairs, degradable spacers, tendon transfers, and more superior capsular reconstruction. The rotator cable is formed by the deep layer of the coracohumeral ligament and the crescent structure running from the anterior insertion site of the supraspinatus to the inferior border of the infraspinatus. The role of the rotator cable is not clear but seems to play a role in reducing tendon stress and influence glenohumeral kinematics. In this laboratory-based cadaver study the anterior cable was reconstructed with semitendinosus allograft treating large "irreparable" rotator cuff defects. Reconstruction resulted in reduced superior migration and subacromial contact forces without inhibiting range of motion.

Use of implantable meshes for augmented rotator cuff repair: a systematic review and meta-analysis

OBJECTIVE

To appraise studies reporting on clinical effectiveness and safety of surgical meshes used to augment rotator cuff repairs (RCRs).

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

MEDLINE, Embase and Cochrane databases were searched between April 2006 and April 2020.

ELIGIBILITY CRITERIA

All studies evaluating adults (≥18 years) undergoing RCR were considered. There were no language restrictions.

DATA EXTRACTION AND SYNTHESIS

Screening, data extraction and quality appraisal were conducted by two independent reviewers. Meta-analysis was conducted using a random-effects models if ≥2 comparative studies reported the same outcome measure. Risk of bias assessment was undertaken for randomised (RoB2, Cochrane) and comparative studies (ROBINS-I, Cochrane).

RESULTS

We included 60 studies, consisting of 7 randomised controlled trials, 13 observational comparative studies and 40 observational case series. All comparative studies reported on shoulder-specific functional outcome scores, 18 on the radiographic occurrence of re-tear and 14 on pain score metrics. All studies contained some risk of bias.Compared with non-augmented repair, a small improvement in shoulder-specific function or pain scores was observed for synthetic patches with a mean improvement of 6.7 points on the University of California Los Angles (UCLA) shoulder score (95% CI 0.1 to 13.4) and 0.46 point reduction on the Visual Analogue Scale (95% CI -0.74 to -0.17), respectively. A reduced likelihood of radiologically observed re-tear was observed for synthetic (risk ratio (RR) 0.41, 95% CI 0.27 to 0.61) and allograft (RR 0.34, 95% CI 0.18 to 0.65) patches. A total of 49 studies reported on the occurrence of complications. Slightly higher crude complication rates were observed following patch-augmented repair (2.1%) than standard repair (1.6%).

CONCLUSIONS

While several studies suggest a decreased failure rate and small improvements in shoulder function and pain following augmented RCR, a paucity of rigorous clinical evaluation, for both effectiveness and safety, prevents firm recommendations.
