Treatment Options for Massive Irreparable Rotator Cuff Tears

Surgical Management of Massive Irreparable Cuff Tears: Superior Capsule Reconstruction and Rotator Cable Reconstruction

PURPOSE OF REVIEW

Massive irreparable rotator cuff tears (MIRCTs) present treatment challenges. Recently, superior capsule reconstruction (SCR) and anterior cable reconstruction have emerged as surgical options, but no single approach is superior. This review provides an overview of SCR and cable reconstruction techniques, including biomechanical studies, clinical outcomes, and surgical considerations.

RECENT FINDINGS

Biomechanical studies show SCR with autografts or allografts improves glenohumeral stability and mechanics. Clinical outcomes of SCR demonstrate improved range of motion, function scores, and pain relief in short-term studies. Anterior cable reconstruction reduces superior humeral head translation and subacromial pressures in biomechanical models. Early clinical studies report improved rotator cuff healing and outcomes for cable reconstruction in specific irreparable tear patterns. SCR and cable reconstruction are viable surgical options for MIRCTs based on early encouraging results. However, higher-level comparative studies with long-term follow-up are still needed. Careful consideration of tear pattern, patient factors, and surgical goals is required to optimize treatment of MIRCTs. Further research is necessary to determine the optimal role for these procedures.

Combined Anterior Latissimus Dorsi and Teres Major Tendon Transfer (aLDTM) for Irreparable Anterosuperior Rotator Cuff Tears

Background

Transfer of the anterior latissimus dorsi and teres major (LDTM) tendons has demonstrated favorable outcomes in patients with irreparable anterosuperior rotator cuff tears1. The objective of this procedure is to restore internal rotation strength, enhance active range of motion, and provide pain relief while preserving the glenohumeral joint.

Description

The incision extended from the coracoid to the inferior border of the pectoralis major tendon, following the deltopectoral interval located laterally to the coracoid. While preserving the pectoralis major tendon, the latissimus dorsi (LD) and teres major (TM) tendons are identified and detached from the humerus without separating the tendons. The LDTM tendons are grasped, and nonabsorbable sutures are placed in a continuous running-locking suture fashion. Traction is applied to the sutures while bluntly releasing the adhesions surrounding the LDTM muscles in order to enable further mobilization and excursion. With the patient's arm positioned in full internal rotation and at 45° of abduction for physiological tensioning, the LDTM tendons are attached 2 cm distal to the lateral edge of the greater tuberosity and lateral to the biceps groove with use of 1 medial anchor and 3 lateral anchors.

Alternatives

Arthroscopic partial repair, superior capsular reconstruction, pectoralis major tendon transfer, and isolated LD tendon transfer are potential alternative treatments. In cases in which these options are not feasible or have been unsuccessful, reverse total shoulder arthroplasty can be considered as a treatment option.

Rationale

Arthroscopic partial repair can provide pain relief, but its effectiveness in improving range of motion and muscle strength is limited2,3. Additionally, there is a high risk of retear, with reported rates as high as 52%4. Superior capsular reconstruction is considered a viable treatment, but it is not recommended in cases involving irreparable subscapularis tears5-7. Pectoralis major transfer may lead to less favorable clinical outcomes in cases in which an irreparable subscapularis tear and an irreparable supraspinatus tear are simultaneously present8-10. In cases of irreparable anterosuperior rotator cuff tears, the transfer of the LD tendon alone may not fully restore the superior migration and anterior subluxation of the humeral head.11. Reverse total shoulder arthroplasty may be another option in these cases, but it does not preserve the glenohumeral joint.

Expected Outcomes

The procedure involves stabilizing the superior translation of the humeral head by rebalancing the force couple, as the TM tendon exhibits scapulohumeral kinematics similar to the subscapularis tendon. Additionally, the procedure effectively reduces anterior glenohumeral subluxation through the combined effect of the posterior line of pull from the combined LDTM tendons and the scapulohumeral kinematics of the teres minor tendon. Also, by fixing the transferred LDTM tendons just distal to the greater tuberosity, the vector becomes less vertical, thereby preventing axillary nerve impingement and achieving appropriate tendon tensioning. The use of this procedure is supported by a study of 30 patients who were followed for a minimum of 2 years1. Significant improvements were observed in various scoring systems, including the pain VAS (visual analogue scale), Constant, ASES (American Shoulder and Elbow Surgeons), UCLA (University of California-Los Angeles), SANE (Single Assessment Numeric Evaluation), and ADLIR (Activities of Daily Living requiring active Internal Rotation) scores. Importantly, there was no significant progression of cuff tear arthropathy observed during the final follow-up. Additionally, preoperative anterior glenohumeral subluxation (15 of 30 patients) was restored in all patients after LDTM tendon transfer.

Important Tips

Careful attention should be paid to the anterior humeral circumflex vessels to prevent bleeding.The radial nerve, passing through the anteroinferior surface of the LDTM tendons, should be carefully identified and protected to avoid iatrogenic injury.To maintain physiologic tension, the patient's arm should be positioned in full internal rotation and 45° of abduction.To avoid axillary nerve impingement, the LDTM tendons should be fixed just distal to the greater tuberosity and lateral to the biceps groove.

Up to date diagnosis and treatment of massive irreparable cuff tears: Results of the survey of the U45 ESSKA Committee

PURPOSE

Irreparable rotator cuff tears are disabling and can severely affect daily life activities, especially when young and active patients are involved. The definition is still debated, and they can have several clinical presentations. The treatment depends on the clinical presentation and the patient's age.

METHODS

The survey was developed by the ESSKA U45 Committee and was uploaded on the ESSKA website. Fifty-seven questionnaires were returned. Several aspects of the diagnosis and treatment of massive irreparable cuff tears were investigated. Moreover, treatment options for specific clinical scenarios were given for posterior-superior and anterior-superior cuff tears in young and old patients.

RESULTS

Fatty degeneration of the muscles was the most common criterion to define an irreparable tear (59.7%). In young patients with external rotation with the arm at side lag, partial repair of the cuff was the most common option (41.8%); in case of external rotation with the arm at side + external rotation at 90° of abduction lag without pseudoparalysis, the most common option was partial repair of the cuff + latissimus dorsi or lower trapezius transfer (39.3%), and in case of external rotation with the arm at side + external rotation at 90° of abduction lag with pseudoparalysis, partial repair of the cuff + latissimus dorsi or lower trapezius transfer was still the most common option (25.5%). The same scenarios in old patients yielded the following results: reverse prosthesis (49.1%), reverse prosthesis (44.6%) and reverse prosthesis ± latissimus dorsi or lower trapezius transfer (44.6%), respectively.

CONCLUSIONS

The present survey clearly confirms that biological options (partial cuff repairs and tendon transfers) are the reference in the case of young patients with deficient cuffs (both posterior and anterior). Reverse shoulder prosthesis is the most common treatment option in old patients in all clinical scenarios.

Age-different BMSCs-derived exosomes accelerate tendon-bone interface healing in rotator cuff tears model

BACKGROUND

Rotator cuff tears (RCTs) are culprit of shoulder pain and dysfunction. Tendon-bone interface (TBI) mal-healing is an essential contributor to retear after RCTs. Consequently, present project was conducted to investigate the role of bone marrow mesenchymal stem cells (BMSCs)-derived exosomes on TBI healing.

METHOD

Young BMSCs (Y-BMSCs) and Aged BMSCs (A-BMSCs) were isolated from Young (3-month-old) and old (24-month-old) SD rats, and their-derived exosomes (A-BMSCs-exo and Y-BMSCs-exo) were identified. RCTs model was established, and A-BMSCs-exo and Y-BMSCs-exo were injected at the rotator cuff using hydrogel as a vehicle. Pathological changes of TBI were observed by HE, Sirius Red and Oil Red O staining. Western blotting and RT-qPCR were applied to assess the expression of extracellular matrix (ECM)-, tendon cell (TCs)-, osteogenic-, tendon-derived stem cell (TDSCs)- and angiogenic-associated proteins and mRNAs in TBI.

RESULT

Y-BMSCs exhibited increased activity, osteogenic and lipogenic abilities than A-BMSCs. After A-BMSCs-exo and Y-BMSCs-exo treatment, TBI displayed massive sharpey's fibers growing along the tendon longitudinally, and a collagen fiber-chondrocyte migration zone forming a typical tendon-noncalcified fibrocartilage-calcified fibrocartilage-bone structure. A-BMSCs-exo and Y-BMSCs-exo significantly upregulated the expression of collagen Col I/II/III, Aggrecan, TNMD, SCX, Runx2, OPN, CD45, Sox2, CD31 and VEGFR2 in TBI. In vitro, A-BMSCs-exo and Y-BMSCs-exo significantly enhanced the activity of TCs and TDSCs, TDSCs stemness, and reduced the osteogenic and lipogenic capacity of TDSCs. The effect of Y-BMSCs-exo was significantly stronger than that of A-BMSCs-exo.

CONCLUSION

BMSCs-derived exosomes facilitate ECM remodeling, osteogenic differentiation, angiogenesis, and stemness of TDSCs, thereby accelerating TBI healing in RCTs, with better outcomes using young individual-derived BMSCs.

Patients With Intact Shoulder Superior Capsular Reconstruction Grafts on Ultrasound Show Significant Improvement in Functional Outcomes at Minimum 2-Year Follow-up

Purpose

To assess the utility of using dynamic ultrasound for postoperative evaluation after superior capsular reconstruction (SCR) by evaluating graft integrity and its correlation with clinical outcomes at a minimum 2-year follow-up.

Methods

A retrospective chart review was conducted to identify patients who underwent SCR between July 2015 and July 2020 with a minimum 2-year clinical and ultrasound follow-up. Clinical outcome measures included Simple Shoulder (SS) and American Shoulder and Elbow Surgeon (ASES) scores. Integrity of the SCR graft was evaluated by dynamic ultrasound.

Results

We evaluated 22 shoulders in 21 patients with a mean follow-up of 44.8 months (range, 24-71 months). The graft was found to be intact by ultrasound evaluation in 82% (18/22). Patients with intact grafts had higher mean SS (11.6 vs 7.8, P = .00079) and ASES (91.2 vs 64.1, P = .0296) scores at latest follow-up compared to those with failed grafts. Those with intact grafts also had significant improvement in SS (3.7 vs 11.6, P < .00001) and ASES (23.2 vs 91.2, P < .00001) scores at latest follow-up compared to their preoperative scores. In contrast, patients with graft failure had no significant improvement in SS (6.3 vs 9.0, P = .123) and ASES (40.4 vs 58.3, P = .05469) scores at latest follow-up compared to their preoperative scores. There was no difference between clinical outcomes at 6 to 12 months vs latest follow-up for both SS (P = .11, P = .5) and ASES (P = .27, P = .21) scores.

Conclusions

SCR grafts were found by ultrasound to be intact in 82% of cases. Patients with intact grafts on ultrasound had significant improvement in functional outcome scores while those with graft failure did not. Functional outcome scores suggest that maximal recovery from this procedure occurs by 6 to 12 months.

Massive and irreparable rotator cuff tear treatment by arthroscopic partial repair with long head of the biceps tendon augmentation provides better healing and functional results than partial repair only

BACKGROUND

The aim of this study was to compare the clinical and radiologic outcomes of 2 treatment methods for massive and irreparable rotator cuff tears (RCTs): partial repair (PR) and PR with long head of the biceps tendon (LHBT) augmentation. Biceps tendon augmentation is believed to promote better healing at the bone-tendon junction, leading to improved clinical and radiologic outcomes.

METHODS

This retrospective comparative study included patients with chronic, massive and irreparable RCTs involving both the supraspinatus (SSP) and infraspinatus muscles. Only patients with failure of nonoperative treatment and at least 1 year of follow-up between 2013 and 2018 were analyzed. The patients were divided into 2 groups based on the chosen treatment method. Irreparability was defined intraoperatively as the inability to achieve sustainable repair of the SSP after complete release, typically corresponding to a Goutallier classification of stage ≥ 3 and Patte classification of stage 3. The clinical assessment protocol involved measurements of range of motion and shoulder strength, as well as the Constant-Murley score (CMS) and Simple Shoulder Test score. Radiologic assessment comprised measurements of the acromiohumeral distance, Hamada classification, Sugaya classification, and Goutallier classification of both the SSP and infraspinatus.

RESULTS

The study included data from 60 patients (30 in each group) with a mean age of 62.5 years and a mean follow-up period of 34.5 months. The retear rate was 43.3% for PR with LHBT augmentation and 73.3% for PR alone (P = .036). During the final examination, statistically significant differences in favor of PR with LHBT augmentation were observed for the CMS (76.2 ± 10.9 vs. 70.9 ± 11.5, P = .034), Sugaya classification (3.5 ± 1.1 vs. 4.1 ± 0.9, P = .035), and acromiohumeral distance (5.8 ± 2 mm vs. 4.7 ± 1.3 mm, P = .021). There were no significant differences between the groups in range of motion, shoulder strength, Hamada classification, Simple Shoulder Test score, and postoperative Goutallier stage.

CONCLUSION

PR with LHBT augmentation for patients with irreparable, massive RCTs provides a lower retear rate and better humeral head centralization, as well as improved results measured by the CMS, compared with PR alone.

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.

[Early effectiveness of arthroscopic superior fulcrum reconstruction in treatment of irreparable massive rotator cuff tear]

Objective

To investigate early effectiveness of arthroscopic superior fulcrum reconstruction in the treatment of irreparable massive rotator cuff tear (IMRCT).

Methods

A retrospective analysis was conducted on the clinical data of 24 patients with IMRCT who met the inclusion criteria between January 2020 and April 2022. Among them, there were 11 males and 13 females with an average age of 56.2 years (range, 42-68 years). There were 12 cases of falling injuries, 3 cases of traction injuries, and the other 9 cases had no obvious causes. The disease duration ranged from 1 to 25 months (median, 6 months). The rotator cuff tears were classified as Hamada grade 2 in 18 cases and grade 3 in 6 cases, and Goutallier grade 1 in 3 cases, grade 2 in 20 cases, and grade 3 in 1 case. All patients were treated with arthroscopic superior fulcrum reconstruction. Visual analogue scale (VAS) score, Constant-Murley score, the University of California at Los Angeles (UCLA) score, and the American Shoulder and Elbow Surgeons (ASES) score were recorded before operation and at 1, 3, 6, and 12 months after operation.

Results

The operations were all successfully completed. The incisions healed by first intention and no related complications occurred. All patients were followed up 12-33 months (mean, 24.6 months). The VAS, Constant-Murley, UCLA, and ASES scores at different time points after operation were superior to those before operation ( P<0.05). All of the above indicators further improved with time. Except for no significant difference in VAS and Constant-Murley scores between 6 and 12 months ( P>0.05), the differences between the other time points were significant ( P<0.05). At 12 months after operation, according to UCLA scoring standard, shoulder joint function was rated as excellent in 4 cases, good in 19 cases, and poor in 1 case, with an excellent and good rate of 96.0%. MRI showed that there was no graft re-tear and the transplanted tendon and bone tunnel healed.

Conclusion

The arthroscopic superior fulcrum reconstruction for IMRCT can effectively relieve the pain, improve the shoulder range of motion, and restore good shoulder function.

Superior capsular reconstruction using the long head of the biceps to treat massive rotator cuff tears improves patients shoulder pain, mobility and function

PURPOSE

Arthroscopic superior capsule reconstruction (SCR) with the long head of the biceps (LHBT) was performed to restore structural stability, force couple balance, and shoulder joint function. This study aimed to evaluate the functional outcomes of SCR using the LHBT over at least 24 months of follow-up.

METHOD

This retrospective study included 89 patients with massive rotator cuff tears who underwent SCR using the LHBT, met the inclusion criteria and underwent follow up for at least 24 months. The preoperative and postoperative shoulder range of motion (forward flexion, external rotation, and abduction), acromiohumeral interval (AHI), visual analog scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score and Constant-Murley score were obtained, and the tear size, and Goutallier and Hamada grades were also investigated.

RESULTS

Compared with those measured preoperatively, the range of motion, AHI, and VAS, Constant-Murley, and ASES scores were significantly improved immediately postoperatively (P < 0.001) and at the 6-month, 12-month, and final follow-ups (P < 0.001). At the last follow-up, the postoperative ASES score and Constant-Murley score increased from 42.8 ± 7.6 to 87.4 ± 6.1, and 42.3 ± 8.9 to 84.9 ± 10.7, respectively; with improvements of 51 ± 21.7 in forward flexion, 21.0 ± 8.1 in external rotation, and 58.5 ± 22.5 in abduction. The AHI increased 2.1 ± 0.8 mm and the VAS score significantly changed from 6.0 (5.0, 7.0) to 1.0 (0.0, 1.0), at the final follow-up. Eleven of the 89 patients experienced retears, and one patient needed reoperation.

CONCLUSION

In this study with at least 24-months of follow-up, SCR using the LHBT for massive rotator cuff tears could effectively relieve shoulder pain, restore shoulder function and increase shoulder mobility to some extent.

Subacromial Balloon Implantation for the Treatment of Irreparable Posterosuperior Rotator Cuff Tears

Despite the development of various therapeutic options, surgical management of irreparable rotator cuff tears (IRCTs) remains controversial. Recently, implantation of a biodegradable subacromial balloon spacer (InSpace, Stryker Corporation; Kalamazoo, MI) has gained considerable interest for the treatment of certain IRCTs. The reported outcome of balloon implantation has not been consistent, likely due to differing indications and technical approaches. The purpose of this article is to present a reproducible arthroscopic technique for implantation of a subacromial balloon and to review the literature published to date, regarding the efficacy and outcomes of this procedure.

Subacromial Balloon Spacer Versus Partial Rotator Cuff Repair in the Treatment of Massive Irreparable Rotator Cuff Tears: Facility Personnel Allocation and Procedural Cost Analysis

Background The subacromial balloon is a novel technology that has shown promise in managing a select patient population with massive irreparable rotator cuff tears. The purpose of this study was to quantify the true facility cost difference between subacromial balloon placement (SBP) and partial rotator cuff repair (PCR). Methodology A prospective cohort of patients with massive irreparable rotator cuff tears randomized to SBP versus PCR between 2015 and 2018 was retrospectively reviewed. Demographic variables, medical comorbidities, and range-of-motion (ROM) outcomes for all patients were recorded. True facility costs with respect to personnel were calculated using a time-driven activity based-costing (TDABC) algorithm and were classified into personnel costs and supply costs. Results Seven patients were treated with PCR compared to nine treated with SBP. No significant differences were observed with respect to demographic characteristics. Postoperative mean external rotation was 37° in SBP patients significantly higher than that of PCR patients at 8° (P = 0.023). Personnel time and cost differences while in the operating room (OR) were significantly less for the SBP ($605.58) compared to PCR ($1362.76) (P < 0.001). Implant costs were higher for SBP when compared to PCR, whereas disposable equipment costs were higher for PCR when compared to SBP. The total mean true facility cost was $7658.00 for SBP, significantly higher than that of PCR at $3429.00 (P < 0.001). Conclusions Despite the substantial reduction in personnel costs seen with SBP, the true facility cost of SBP was significantly higher than that of PCR. As this novel technology is used more ubiquitously and its price is negotiated down, the cost savings seen in personnel and OR time will become more significant. Future prospective cost analyses should follow up on the changes in implant costs and account for potential anesthesia cost savings.

Effective Management of Bilateral Massive Irreparable Rotator Cuff Tears through Implantation of Subacromial Balloon Spacers

Introduction

Massive irreparable rotator cuff tears are challenging pathologies with many treatment modalities and therapeutic approaches. In patients with certain indications, the subacromial balloon spacer can effectively alleviate pain and improve function, in a manner that may be superior to other management options.

Case Report

We report the case of a 64-year-old active male who had previously underwent a subacromial balloon placement in his right shoulder and an arthroscopic rotator cuff repair procedure on his left shoulder. He later presented with persistent pain and disability in his left shoulder and opted to undergo a second subacromial balloon placement on his left side. To the best of our knowledge, this is the first case of bilateral subacromial balloon placement procedure in the literature.

Conclusion

The subacromial balloon is a safe treatment modality for irreparable rotator cuff tears, and its introduction into bilateral shoulders can provide an easier recovery and rehabilitation when compared to other more invasive procedures.

Massive Irreparable Rotator Cuff Tears: Which Patients Will Benefit from Physiotherapy Exercise Programs? A Narrative Review

Massive irreparable rotator cuff tears can cause significant shoulder pain, disability and reduction in quality of life. Treatment approaches can be operative or non-operative. Operative approaches include reverse total shoulder arthroplasty, arthroscopic debridement, partial rotator cuff repair, subacromial balloon spacers, superior capsule reconstruction, and tendon transfer procedures. Non-operative approaches include physiotherapy exercise programs and corticosteroid injections. There are no randomized controlled trials comparing the different treatment approaches. It is therefore challenging for clinicians to advise patients on what is their best treatment pathway. Physiotherapy exercise programs are less expensive and have lower risks for patients than surgical approaches. However, the success of physiotherapy in patients with massive irreparable rotator cuff tears is highly variable with published success rates of 32-96%. Several cohort studies have sought to identify if certain factors are predictive of success with physiotherapy. Several biomechanical factors were identified as possibly being related to a successful or unsuccessful outcome following physiotherapy, with complete tear of subscapularis demonstrating the strongest evidence. However, there were no appropriately designed prognostic studies. There has been a strong emphasis on biomechanical factors. Other domains such as psychosocial factors, which are important in similar patient populations, have not been explored. We recommend that further research is needed in this area and should include randomized controlled trials comparing treatment approaches and longitudinal prospective prognostic studies to identify predictors of treatment success.

Re-Tear Rates Following Rotator Cuff Repair Surgery

Aim Re-tears following rotator cuff repair surgery are a common occurrence. Previous studies have identified several factors that have been shown to increase the risk of re-tears. The purpose of this study was to evaluate the rate of re-tear following primary rotator cuff repair and to identify the factors that may contribute to this rate. Method The authors performed a retrospective review, looking at rotator cuff repair surgeries performed between May 2017 and July 2019 performed in a hospital by three specialist surgeons. All methods of repair were included. All patients' medical data, including imaging and operation records, were reviewed. Results A total of 148 patients were identified. Ninety-three males and 55 females with a mean age of 58 years (range 33-79 years). Thirty-four patients (23%) had post-operative imaging with either magnetic resonance imaging or ultrasound, where it was found that 20 (14%) had a confirmed re-tear. Of these patients, nine went on to have further repair surgery. The average age of the re-tear patients was 59 (age range 39-73) and 55% were female. The majority of the re-tears were from chronic rotator cuff injuries. This paper did not identify any correlation between smoking status or diabetes mellitus and re-tear rates. Conclusions This study indicates that re-tear after rotator cuff repair surgery is a common complication. The majority of studies find increasing age to be the biggest risk factor; however, this was not the case in our study which found females in their 50s to have the highest rate of re-tear. Additional research is required to understand what factors can contribute towards rotator cuff re-rupture rates.

Assessment of the effectiveness of surgical treatment of patients with massive ruptures of rotator cuff tendons using latissimus dorsi tendon transposition

Rotator cuff ruptures are the most common injuries of shoulder joint with an incidence of about 20 %. This pathology is more common in adults over 60 years of age because it is caused by degenerative changes in the tendon. Massive injuries account for 10–40 % of all rotator cuff injuries. Currently, there is no unified surgical tactics for the treatment of patients with massive ruptures of rotator cuff tendons.The aim. To assess the efficiency of transposition of the latissimus dorsi tendon in patients with massive ruptures of the rotator cuff tendon.Materials and methods. The study included 15 patients with Patte stage III massive ruptures of the rotator cuff who had transposition of the latissimus dorsi tendon.Results. The article presents clinical cases of surgical treatment of patients. The following criteria were assessed: mean age; time since injury; duration of the surgery; blood loss volume; functional results by the ASES (American Shoulder and Elbow Surgeons) Shoulder Score. Taking into account the ASES Shoulder Score indicators 1 year after the surgical treatment, the following results were obtained: excellent results – in 9 (53.3 %) cases; good results – in 1 (13.4 %) case; satisfactory results – in 5 (33.3 %) cases.Conclusion. When preserving the articular cartilage, the method of choice in the treatment of patients with massive ruptures of rotator cuff tendons is transposition of the latissimus dorsi tendon. At the same time, an incomplete restoration of the function of the injured limb was registered in 33.3 % of patients, which requires further study and modification of the known method of transposition of the latissimus dorsi tendon.

Irreparable Massive Rotator Cuff Tears: Subacromial Balloon Surgical Technique

Massive irreparable rotator cuff tears pose a significant challenge for both the treating orthopedic surgeon and patient. Surgical treatment options for massive rotator cuff tears include arthroscopic debridement, biceps tenotomy or tenodesis, arthroscopic rotator cuff repair, partial rotator cuff repair, cuff augmentation, tendon transfers, superior capsular reconstruction, subacromial balloon spacer, and ultimately reverse shoulder arthroplasty. The present study will provide a brief overview of these treatment options along with a description of the surgical technique for subacromial balloon spacer placement.

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.

Five trials (n = 297 participants, average age 66.7 years, 55% male) were included in analysis. Three trials compared exercise to another non-surgical intervention and 2 trials compared exercise to surgery. At 12 months a significant improvement in pain of 0.47 (95% CI 0.07-0.88, I² = 53%, REM) favoured the surgical group and a significant improvement in shoulder external rotation ROM of 9° (95% CI 2.16-16.22, I² = 0%, FEM) favoured the exercise group. The median CERT score was 7/19 (range 4-12). The certainty of evidence was low or very low across all outcomes.

CONCLUSION

A paucity of high-quality research on the role of exercise in the management of L-MRCTTs exists with substantial discrepancies in the reporting of the exercise interventions in the published research.
