Abstract
Bursal acromial reconstruction/resurfacing, acromiograft and biologic tuberoplasty are all terms used to describe the concept of fixing a graft (human dermal allograft or fascia lata) to the undersurface of the acromion or onto the greater tuberosity with the aim of achieving pain relief and improved function in patients with massive irreparable cuff tears (MIRCTs). The rationale for these procedures is based on the biomechanical concept that an interpositional spacer can reverse superior migration of the humeral head, increase acromiohumeral distance, reduce subacromial contact pressure and limit painful bone-on-bone contact. These types of procedures are postulated to offer potential advantages (cost savings related to use of implants, long-term biologic solution, technical ease of surgery and short surgical time), over other options for MIRCTs, particularly superior capsule reconstruction and in some respects the subacromial balloon. However, these advantages remain unproven because published clinical studies are sparse. Furthermore, there is no current consensus on indications, technique, or optimum graft choice.

Arthroscopy 2024:S0749-8063(24)00454-7. [PMID: 38925233 DOI: 10.1016/j.arthro.2024.06.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2024] [Revised: 05/26/2024] [Accepted: 06/09/2024] [Indexed: 06/28/2024]
Abstract
PURPOSE To investigate the effectiveness of bursal acromial resurfacing (acromiograft) on acromiohumeral distance, subacromial contact area, and pressure in a cadaveric model of massive rotator cuff tear. METHODS Eight fresh-frozen cadaveric shoulders were tested using a customized shoulder testing system. Humeral head translation, subacromial contact pressure, and the subacromial contact area were evaluated across 4 conditions: (1) intact shoulder; (2) simulated massive rotator cuff tear, (3) 3-mm acromiograft condition, and (4) 6-mm acromiograft condition. The acromiografts were simulated using Teflon and a reported technique. The values were measured at 0°, 20°, and 40° abduction and 0°, 30°, 60°, and 90° external rotation for each abduction status. RESULTS Compared with a massive cuff tear, the 6-mm acromiograft significantly reduced the superior translation of the humeral head at all abduction/external rotation angles (P < .05). The 3-mm acromiograft also decreased superior translation of the humeral head compared with massive cuff tear, but not all differences were significant. The 3- and 6-mm acromiografts significantly decreased the subacromial contact pressure and increased the subacromial contact area in almost all positions (P < .05). The 3-mm acromiograft maintained biomechanical properties similar to the intact condition, whereas the 6-mm acromiograft increased the contact area. CONCLUSIONS This biomechanical study demonstrated that both 3- and 6-mm acromiografts using Teflon in a cadaveric model of a massive cuff tear resulted in recentering of the superiorly migrated humeral head, increased the subacromial contact area, and decreased the subacromial contact pressure. The 3-mm graft was sufficient for achieving the intended therapeutic effects. CLINICAL RELEVANCE The acromiograft can normalize altered biomechanics and may aid in the treatment of massive cuff tears. Because grafting the acromion's undersurface is new with limited clinical outcomes, further observation is crucial. Using a Teflon instead of an acellular dermal matrix allograft for bursal acromial resurfacing could yield different results, requiring careful interpretation.

Abstract
Background Recently, among the various method for irreparable rotator cuff tears, the "tension-free allodermis graft technique" has been introduced as a method for arthroscopic biologic tuberoplasty(ABT) and bursal acromial reconstruction(BAR).The objective was to analyze the outcomes of ABT and BAR combination surgical technique. Methods Eighteen cases who underwent simultaneous ABT and BAR procedures were retrospectively recruited. Before the surgery and at one year post-surgery, the researchers assessed the patients' Visual Analog Scale(VAS), American Shoulder and Elbow Surgeons(ASES) scores, pain scores, range of motion(ROM), retear, and acromiohumeral distance (AHD). Results One year post-surgery, both the VAS pain scores, ASES scores, and ROM showed statistically significant improvement compared to before the surgery. Upon reviewing the radiological results, the AHD significantly improved from 4.3 ± 4.1 mm before surgery to 9.2 ± 1.9 mm at one year post-surgery (p < 0.001). Moreover, in the one year follow-up, there was no observed failure of the allodermis graft in any of the cases. Conclusion The combination of ABT and BAR demonstrated significantly improved clinical outcomes after surgery, showing a substantial increase in AHD and preventing graft failure effectively.

Abstract
PURPOSE OF REVIEW The purpose of the review is to provide an updated overview of a relatively novel but controversial surgical device (InSpace subacromial balloon, Stryker, Kalamazoo, MI) that can be readily incorporated into the armamentarium of the shoulder surgeon. The authors review the critical clinical and surgical decision-making aspects of InSpace. A recommended surgical technique and rehabilitation protocol are outlined. The authors present a nuanced view of the balloon spacer in the continuum of care of the irreparable rotator cuff tear. RECENT FINDINGS Within the last year, two Level I clinical trials have been published, and the data from these studies offer conflicting evidence regarding the utility of the subacromial balloon spacer. The current review contrasts these two recent studies and offers a framework by which the available evidence can be practically understood with respect to clinical decision-making. The literature currently supports a limited indication for use of InSpace: the elderly, low-demand patient with preserved active range of motion with an operatively irreparable, posterosuperior rotator cuff tear with an intact subscapularis. The InSpace subacromial balloon spacer is a simple device that can yield substantial improvements in clinical outcomes among a subset of patients with irreparable rotator cuff tears. InSpace is not a panacea for the complex, irreparable rotator cuff tear. Individualized decision-making is necessary in this diverse and challening patient population.

Abstract
Purpose To evaluate the biomechanical effects of acellular human dermal allograft tuberoplasty (AHDAT) in a cadaveric model of an irreparable supraspinatus + anterior one-half infraspinatus (stage III) rotator cuff tear. Methods Eight cadaveric shoulders were tested at 20°, 40°, and 60° of glenohumeral abduction (AB) and 0°, 30°, 60°, and 90° of external rotation (ER). Superior humeral translation, acromiohumeral distance, and subacromial contact were quantified for 4 conditions: (1) intact, (2) stage III tear (entire supraspinatus and anterior one-half infraspinatus), (3) single-layer AHDAT, and (4) double-layer AHDAT. Results Stage III tear significantly increased superior translation at 20° and 40° AB and all ER angles and at 60° AB/60° ER (P ≤ .045 vs intact). Compared to the stage III tear, the single-layer AHDAT significantly decreased superior translation at 60° AB/60° ER (P = .003), whereas the double-layer AHDAT significantly decreased superior translation at 40° and 60° AB at all ER angles except 60° AB/0° ER (P ≤ .028). The stage III tear significantly decreased acromiohumeral distance at 20° AB (P ≤ .003); both grafts increased acromiohumeral distance to intact levels (P ≥ .055 vs intact). Stage III tear increased subacromial contact pressure at 20° and 40° AB/0° and 30° ER and at 60° AB/30° and 60° ER (P ≤ .034). Both AHDAT groups decreased contact pressure at 40° AB/30° and 60° ER back to intact, whereas the double-layer AHDAT also decreased contact pressure at 20° AB/0° and 60° ER and 60° AB/30° ER (P ≥ .051 vs intact). Conclusions Both single- and double-layer grafts for AHDAT improved superior translation, subacromial contact characteristics, and acromiohumeral distance after a stage III rotator cuff tear, with varying effectiveness due to the position-dependent nature of greater tuberosity to acromial contact with abduction. Clinical Relevance The best treatment for massive or irreparable rotator cuff tears is a matter of concern. The results of this study will help determine whether an acellular human dermal allograft tuberoplasty is a potential treatment option worthy of further investigation.

Abstract
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.

Abstract
BACKGROUND Biomechanical testing of abduction moment arms presents a useful method to assess the contributions of individual rotator cuff muscles to glenohumeral function. This study aimed to investigate the changes in abduction moment arms after the treatment of supraspinatus tears with superior capsular reconstruction (SCR), bursal acromial reconstruction (BAR), and a combined SCR-BAR procedure, all with human dermal allograft. METHODS We tested 7 fresh-frozen cadaveric specimens under 6 conditions: (1) intact, (2) 50% supraspinatus tear (partial tear), (3) 100% supraspinatus tear, (4) SCR, (5) SCR combined with BAR, and (6) BAR. In each condition, the moment arms for the individual muscles of the teres minor, subscapularis, and infraspinatus were calculated throughout 90° of abduction using a motion capture system. Analysis of variance and post hoc Tukey testing were performed to determine significance. RESULTS In the teres minor, the moment arms in the SCR (11.9 mm), BAR (10.1 mm), and SCR-BAR (11.9 mm) conditions were greater than those in the intact (8.5 mm; P = .001, P = .001, and P = .001, respectively), partial tear (9.1 mm; P = .001, P = .128, and P = .001, respectively), and complete tear (8.8 mm; P = .001, P = .011, and P = .001, respectively) conditions. Similarly, in the subscapularis, the moment arms in the SCR (13.4 mm), BAR (13.8 mm), and SCR-BAR (13.5 mm) conditions were greater than those in the intact (10.6 mm; P = .006, P = .001, and P = .003, respectively) and partial tear (10.4 mm; P = .006, P = .001, and P = .003, respectively) conditions. In the teres minor, the SCR (11.9 mm) and SCR-BAR (11.9 mm) conditions were also found to have significantly increased moment arms compared with the BAR condition (10.1 mm; P = .001 and P = .001, respectively). In the infraspinatus, the BAR condition (13.8 mm) was found to have a significantly decreased moment arm compared with the partial tear condition (15.8 mm, P = .026), with no other significant findings between conditions. CONCLUSION Our results suggest that the moment arm contributions of the individual muscles comprising the rotator cuff can change after reconstruction to compensate for tears. SCR and SCR-BAR increase the moment arms in the teres minor and subscapularis, potentially allowing for increased abduction ability.

Abstract
PURPOSE To evaluate the effect of an irreparable posterosuperior rotator cuff tear (PSRCT) on glenohumeral joint loads and to quantify improvement following superior capsular reconstruction (SCR) using an acellular dermal allograft. METHODS Ten fresh-frozen cadaveric shoulders were tested using a validated dynamic shoulder simulator. A pressure mapping sensor was placed between the humeral head and glenoid surface. Each specimen underwent the following conditions: (1) native, (2) irreparable PSRCT, (3) SCR using a 3mm-thick acellular dermal allograft. Glenohumeral abduction angle (gAA) and superior humeral head migration (SM) were measured using 3D motion tracking software. Cumulative deltoid force (cDF) and glenohumeral contact mechanics, including contact area (gCA) and contact pressure (gCP), were assessed at rest,15°,30°,45°, and maximum angle of glenohumeral abduction. RESULTS The PSRCT resulted in a significant decrease of gAA along with an increase in SM, cDF, and gCP (P<.001, respectively). SCR did not restore native gAA (P<.001), however, SM was significantly reduced (P<.001). Further, SCR significantly reduced deltoid forces at 30° (P=.007) and 45° of abduction (P=.007) when compared to the PSRCT. SCR did not restore native cDF at 30°(P=.015), 45°(P<.001), and maximum angle (P<.001) of glenohumeral abduction. Compared to the PSRCT, SCR resulted in a significant decrease of gCP at 15°(P=.008), 30°(P=.002), and 45°(P=.006). However, SCR did not completely restore native gCP at 45° (P=.038) and maximum abduction angle (P=.014). CONCLUSION In this dynamic shoulder model, SCR only partially restored native glenohumeral joint loads. However, SCR significantly decreased glenohumeral contact pressure, cumulative deltoid forces, and superior migration, while increasing abduction motion, when compared to the posterosuperior rotator cuff tear. CLINICAL RELEVANCE These observations raise concerns regarding the true joint preserving potential of SCR for an irreparable posterosuperior rotator cuff tear, along with its ability to delay progression of cuff tear arthropathy and eventual conversion to reverse shoulder arthroplasty.

Abstract
The management of irreparable rotator cuff tears in active patients without severe osteoarthritis is challenging. Retracted tears of the superior cuff result in devastating glenohumeral kinematics and decreased shoulder function. Surgical solutions such as superior capsular reconstruction (SCR) or tendon transfers may improve shoulder function. Regarding SCR, the superior capsule has been described as a static stabilizer allowing for the centering of the humeral head. However, some bases for SCR are based on biomechanical studies that should be regarded as time zero, absent healing, and generally oversimplified as ball-and-socket research rather than replicating complex functional shoulder kinematics. SCR may be waning in popularity. SCR using autograft may, or may not, prove effective in the long run. For now, it remains to be seen whether SCR is superior to partial repair of the rotator cuff.

Abstract
While functional reconstruction of massive irreparable rotator cuff tears remains a challenge, current techniques aimed at recentering and preventing superior migration of the humeral head allow for clinical and biomechanical improvements in shoulder pain and function. Recentering of the glenohumeral joint reduces the moment arm and helps the deltoid to recruit more fibers, which compensates for insufficient rotator cuff function and reduces joint pressure. In the past, the concept of a superior capsular reconstruction with a patch secured by suture anchors has been used. However, several innovative arthroscopic treatment options have also been developed. The purpose of this article is to present an overview of new strategies and surgical techniques and if existing present initial clinical results. Techniques that will be covered include rerouting the long head of the biceps tendon, utilization of the biceps tendon as an autograft to reconstruct the superior capsule, utilization of a semitendinosus tendon allograft to reconstruct the superior capsule, superior capsular reconstruction with dermal allografts, and subacromial spacers.

Abstract
Massive irreparable rotator cuff tears in patients for whom arthroplasty is not an option can be a challenging clinical scenario for shoulder surgeons to manage. To achieve the best patient outcomes, a myriad of options has been presented in the literature, including debridement with biceps tenotomy or tenodesis, various tendon transfer procedures, superior capsular reconstruction, biceps tendon rerouting, bursal acromion resurfacing, balloon spacers, and tuberoplasty. While debridement with biceps tenotomy and superior capsular reconstruction have historically provided improvements in patient-reported outcomes, high rates of arthritis progression and failure of graft healing have been noted with these techniques, respectively. The superior capsular reconstruction has also proven to be technically challenging. The biologic tuberoplasty procedure was developed after several studies noted a lack of correlation between graft healing and improvement in patient-reported outcomes in superior capsular reconstructions, as long as the tuberosity remained covered with the graft. We present a technically efficient and expedited technique using an acellular human dermal allograft.

Abstract
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.

Abstract
Failed rotator cuff repairs present a complex issue for treating surgeons. Many methods of management exist for this pathology including revision repair with biologic augmentation, repairs with allograft, tendon transfers, superior capsular reconstruction, balloon arthroplasty, bursal acromial reconstruction, and reverse total shoulder arthroplasty. This review discusses the current literature associated with these management options.

Abstract
For the treatment of irreparable posterosuperior rotator cuff tears of the supraspinatus and infraspinatus, superior capsular reconstruction (SCR) has continued to supplant other less successful and/or reproducible techniques, including partial rotator cuff repair and latissimus tendon transfer. After its initial description utilizing a folded fascia lata autograft with a thickness of up to 8 mm, many in North America adapted their surgical technique to use commercially available human dermal allograft to mitigate donor site morbidity. Early series have revealed the importance of graft thickness in predicting risk of radiographic or clinical failure. As a result, there has been a renewed interest in increasing the thickness of an SCR graft to further prevent superior humeral head translation and diminish subacromial contact pressures and secondary radiographic, or more importantly, clinical failure. Some authors have sought to augment dermal allografts for increased stiffness, whereas other authors have explored the option of adding a separate graft on the undersurface of the acromion for a bursal acromial reconstruction. Although this increased graft thickness may result in improved acromiohumeral distance and clinically significant patient improvement, secondary graft retear and acromial osteolysis may develop due to increased friction or "overstuffing" of the subacromial space.

Abstract
Treatment options for massive irreparable rotator cuff tears continue to evolve. Recently bursal acromial reconstruction (BAR) has been described as an additional option to reduce pain and improve comfort. As originally described, an acellular dermal allograft is secured to the underside of the acromion as an interposition graft. We describe a modified technique that facilitates suture passage, reduces entanglement, and optimizes contact between the bone-graft interface.

Abstract
PURPOSE To investigate the effect of bursal acromial reconstruction (BAR) using an acellular dermal allograft on glenohumeral joint kinematics including maximum abduction angle, glenohumeral superior translation, cumulative deltoid force, and subacromial contact pressure. METHODS In this dynamic biomechanical cadaveric shoulder study, 8 fresh-frozen cadaveric shoulders (age 53.4 ± 14.2 years, mean ± standard deviation) were tested using a dynamic shoulder testing system. Maximum abduction angle (MAA), glenohumeral superior translation (ghST), maximum cumulative deltoid force (cDF), and subacromial peak contact pressure (sCP) were compared across 3 conditions: (1) intact shoulder; (2) massive retracted irreparable posterosuperior rotator cuff tear (psRCT) according to Patte III; and (3) BAR. Additionally, humeral head containment was measured using contact pressure. RESULTS Compared with the simulated psRCT, BAR significantly increased mean MAA and significantly decreased ghST (P < .001, respectively) and cDF (P = .017) Additionally, BAR was found to significantly decrease sCP compared with psRCT (P = .024). CONCLUSION In a dynamic biomechanical cadaveric shoulder simulator, resurfacing the undersurface of the acromion using the BAR technique leads to significantly improved ghST, MAA, cDF, and sCP compared with the irreparable rotator cuff tear. CLINICAL RELEVANCE With the BAR technique, native humeral containment may be restored, which can potentially delay progressive subacromial and glenoidal abrasive wear and improve overall shoulder function. As such, the proposed BAR technique can be considered as a technically feasible and potentially cost- and timesaving procedure, as no bone anchors are needed, glenoidal or humeral side graft ruptures can be avoided, and postoperative rehabilitation can be started immediately. However, future clinical studies are needed.

Abstract
Introduction Current understanding of the biomechanical effects of treatment options for irreparable rotator cuff (RC) tears is lacking. This study examines how shoulder muscle lengths and excursions are affected by superior capsular reconstruction (SCR), bursal acromial reconstruction (BAR), and SCR with BAR, following a complete supraspinatus tear. Method Six fresh-frozen cadaveric shoulders were examined. Deltoid and RC muscle lengths were measured at 0, 30, 45, 60, and 90° of shoulder abduction under six conditions: (1) intact, (2) partially torn supraspinatus, (3) completely torn supraspinatus, (4) SCR, (5) SCR with BAR, and (6) BAR. Muscle excursions from 0–90° of abduction were then calculated. Results Subscapularis muscle lengths after SCR, BAR, and SCR with BAR were significantly greater (post-hoc Tukey HSD test; p < .01) compared to the other conditions. Supraspinatus, infraspinatus, teres minor, and deltoid lengths were not significantly different (ANOVA test; p > .01) between the conditions. All muscle excursions remained statistically similar between the conditions (ANOVA test; p > .01). Conclusion These findings demonstrate that the use of SCR, BAR, or SCR with BAR for a complete supraspinatus tear, may increase subscapularis muscle length while maintaining other shoulder muscle lengths. An increase in subscapularis length can allow for more effective subscapularis muscle strengthening and increased compensatory function in the long term. Additionally, all shoulder muscle excursions are preserved after partial or complete supraspinatus tears and after SCR, BAR, or SCR with BAR. Therefore, these surgical treatments can initially normalize shoulder muscle function during 0–90° of abduction, after an irreparable supraspinatus tear.

Abstract
Massive and irreparable rotator cuff tears remain a major challenge for orthopaedic surgeons and several surgical options have been accepted for different patterns of irreparable cuff tears. However, the high-cost and technical complexity of some surgeries and the inconsistent clinical results of others, leave room for the search for surgical options that can offer a good balance between technical simplicity, a lower cost and an acceptable clinical result.The rationale behind some available techniques includes lowering the humeral head, which enables a more efficient balance of the force couples around the shoulder during rehabilitation. The interpositional arthroplasty with a biodegradable balloon, the Superior Capsule Reconstruction and, more recently, subacromial resurfacing with a dermal allograft have been presented as valid options to address that purpose.This technical note presents Subacromial Resurfacing with fascia lata as an option for the treatment of irreparable rotator cuff tears in the elderly population. Its low-cost and reasonable technical demand, along with the need for further elucidation of the ideal indications and technical optimization of other available techniques may open up room for the success of this option.

Abstract
We present the technique of biologic tuberoplasty, where an acellular dermal allograft is used to cover the tuberosity in patients with massive irreparable cuff tears to prevent bone-to-bone contact between the tuberosity and acromion when active elevation is attempted. This technique can be performed in patients with massive rotator cuff tears who are low-demand and have significant medical comorbidities, poor bone quality, or who are not candidates for a reverse shoulder arthroplasty or who cannot tolerate a lengthy rehabilitation protocol. It is less time-consuming than a superior capsule reconstruction and more bone-sparing than traditional tuberoplasty. Patients with massive rotator cuff tears involving the supraspinatus and a portion of the infraspinatus lose their force couple, leading to superior humeral head migration with abutment of the tuberosity against the acromion upon deltoid activation. The center of rotation moves superiorly with deltoid contraction, developing an acromiohumeral articulation. This results in bone-to-bone contact between the acromion and humerus, leading to pain and acetabularization of the acromion over time. Coverage of the tuberosity with the acellular dermal allograft acts as an interpositional tissue and prevents bone-to-bone contact between the tuberosity and acromion.
