Abstract
Background Tendon transfers in conjunction with reverse total shoulder arthroplasty can significantly improve functional outcomes in patients with glenohumeral arthritis and irreparable rotator cuff deficiency. There have been multiple promising new techniques described within the last 20 years that shoulder surgeons should become familiar with. Methods The authors reviewed the literature on tendon transfers in the setting of reverse total shoulder arthroplasty. Procedures to restore various shoulder functions were described including surgical anatomy, techniques, pearls and pitfalls, and photos. Results Subscapularis insufficiency can be reconstructed with a pectoralis major transfer or latissimus dorsi transfer, with the latter having better clinical outcomes and a more anatomic line of pull. Posterosuperior rotator cuff deficiency can be reconstructed with a latissimus transfer (L'Episcopo transfer) or lower trapezius transfer, with the latter proving superior in biomechanical and short-term studies. Deltoid deficiency can be reconstructed with a pedicled upper pectoralis major transfer. Massive proximal humerus bone loss can be reconstructed with an allograft-prosthetic composite, and any of the aforementioned transfers can be utilized in this setting as well. Conclusion Tendon transfers in conjunction with reverse shoulder arthroplasty can significantly improve functional outcomes in patients with glenohumeral arthritis and irreparable rotator cuff deficiency. There have been multiple promising new techniques described within the last 20 years that shoulder surgeons should become familiar with.

Increased latissimus dorsi and teres major muscle volume after anterior transfer for irreparable anterior superior rotator cuff tear: correlation with improved internal rotation strength. Arch Orthop Trauma Surg 2024; 144:1491-1502. [PMID: 38316700 DOI: 10.1007/s00402-023-05192-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 12/19/2023] [Indexed: 02/07/2024]
Abstract
INTRODUCTION While the well-established correlation between increased muscle volume and enhanced muscle strength is widely recognized, there have been no studies assessing volumetric muscle changes in transfer surgery in the shoulder. This study aimed to evaluate changes in transferred muscle volume and their clinical implications in anterior latissimus dorsi and teres major (aLDTM) tendon transfer in patients with anterior superior irreparable rotator cuff tears (ASIRCTs). MATERIALS AND METHODS The study retrospectively examined 40 patients who underwent aLDTM tendon transfers for ASIRCTs between August 2018 and January 2022. Using ImageJ software, the LDTM muscle was segmented in T2-weighted oblique axial images, and total muscle volume (tLDTMV) of both immediate and postoperative 1-year were calculated. Pearson correlation analysis was used to determine the correlation between ΔtLDTMV and ΔASES scores, Δactive-ROM, and Δstrength. RESULTS The current study revealed an 11.4% increase in tLDTMV at 1-year postoperative. Patients were grouped based on postoperative ASES score: Group 1 (Optimal, n = 17) and Group 2 (Suboptimal, n = 23). Although tLDTMVimmediate postoperative values were similar between groups (P = 0.954), tLDTMV1-year postoperative value was significantly higher in Group 1 compared to Group 2 (P = 0.021). In correlation analysis, ΔtLDTMV showed significant correlations with ΔASES score (r = 0.525, P < 0.001), ΔaROM of forward elevation (FE) (r = 0.476, P = 0.002), ΔaROM of internal rotation (IR) at back (r = 0.398, P = 0.011), Δstrength of FE (r = 0.328, P = 0.039), Δ strength of IR at 90° abduction (r = 0.331, P = 0.037), and IR at side (r = 0.346, P = 0.029). CONCLUSIONS Significant increase in tLDTMV was observed at 1-year postoperative for ASIRCT patients. Notably, greater ΔtLDTMV exhibited a correlation with better ASES scores, increased aROM and strength in both FE and IR. Nevertheless, further research is required by employing more robust standardized measurement tools and a larger sample size.

Arch Orthop Trauma Surg 2024; 144:1473-1483. [PMID: 38285220 DOI: 10.1007/s00402-023-05196-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2023] [Accepted: 12/19/2023] [Indexed: 01/30/2024]
Abstract
INTRODUCTION Treating global irreparable rotator cuff tears (GIRCTs) that involve both antero-and postero-superior cuff tendon tears could be a challenging problem. There has been limited joint-preserving treatment options in high-demand patients with minimal glenohumeral arthritis. The study aims to assess the clinical outcome of combined anterior latissimus dorsi and teres major tendon (aLDTM) transfer for patients with both GIRCTs and minimal glenohumeral arthritis. MATERIALS AND METHODS This retrospective study included patients who underwent combined aLDTM transfer for GIRCTs between 2018 May and 2020 October. Clinical outcomes include pain VAS, Constant, American Shoulder and Elbow Society (ASES), University of California Los Angeles (UCLA), activities of daily living requiring active internal rotation (ADLIR) score, active range of motion (aROM), strength, rates of pseudoparalysis or pseudoparesis reversal and return to work. Radiographic assessment included the acromiohumeral distance (AHD), Hamada grade, and transferred tendon integrity at final follow-up. RESULTS 23 patients (mean age: 64.7 ± 5.9 years [55-74]) were included and the mean follow-up period was 28.2 ± 4.3 [24‒36] months. Postoperatively, VAS, Constant, ASES, UCLA, and ADLIR scores significantly improved at final follow-up (P < .001). Postoperative aROM was significantly improved in forward elevation (FE) to 129° ± 29°, abduction (ABD) to 105° ± t3°, and internal rotation (IR) at back to 5.9 ± 2.5. Strength of both FE and IR were also significantly improved (P < .001). Patients with preoperative pseudoparalysis (2 of 4 patients) and pseudoparesis (6 of 6 patients) experienced a reversal. No significant change in AHD and hamada grade was confirmed at final follow-up. 3 patients experienced partial tear of the transferred tendon. CONCLUSIONS In this study, we found significant improvement in clinical outcomes with no significant progression of arthritis by final follow-up. The aLDTM transfer could be an alternative choice of joint-preserving treatment option for young and active patients with GIRCTs and minimal glenohumeral arthritis. However, large and long-term studies should be conducted to establish its adequacy. STUDY DESIGN Case series. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE OF REVIEW Irreparable subscapularis tears, especially in younger patients with higher functional demands, present a challenging entity. Pectoralis major and latissimus dorsi tendon transfers are commonly considered for surgical management of this pathology, yet no consensus exists regarding the superior option. The purpose of this article is to review the most current tendon transfer techniques for irreparable subscapularis tears. RECENT FINDINGS For decades, transfer of the pectoralis major has been considered the gold standard technique for irreparable subscapularis tears. This transfer was found to reduce pain and improve functional outcome scores, yet range of motion and force of internal rotation were not maintained in long-term follow-up studies. The latissimus dorsi tendon transfer for the same indications has demonstrated biomechanical superiority in recent cadaveric studies with promising short-term results clinically. Both pectoralis major and latissimus dorsi tendon transfers improve outcomes of patients with irreparable subscapularis tears. Future comparative studies are still needed to determine superiority amongst techniques.

Abstract
Primary repair of acute subscapularis (SSC) tears provides excellent results, but tendon retraction, muscle atrophy, fatty infiltration, and humeral head migration may render a more chronic tear irreparable. These irreparable SSC tears present a diagnostic and treatment challenge for orthopaedic surgeons. Careful physical examination and imaging evaluation can help to distinguish those with reparable versus irreparable tears, but they are still not very reliable due to the methodological limitations of current evidence. Therefore, future research using 3D and quantitative measurement techniques is necessary to better predict the irreparability of the SSC. When conservative treatment of an irreparable SSC tear fails, reversed shoulder arthroplasty has been established as the preferred treatment option for older, low-demand patients with arthropathy, providing reliable improvements in pain and function. In younger patients without significant arthropathy, musculotendinous transfers are the treatment of choice. The pectoralis major transfer is historically the most frequently performed procedure and provides improved range of motion and pain relief, but fails to adequately restore strength and shoulder function. The latissimus dorsi transfer has gained increased interest over the last few years due to its biomechanical superiority, and early clinical studies suggest improved outcomes as well. More recently, anterior capsular reconstruction has been proposed as an alternative to musculotendinous transfers, but clinical data are completely lacking. Future high-quality randomised controlled trials are necessary to reliably compare the different musculotendinous transfers and anterior capsular reconstruction.

Abstract
Failed rotator cuff repairs pose several challenges due to the high incidence rate, complexity, and range of symptoms. We propose an overview for assessing and treating failed rotator cuff repairs. For active young patients, attempt revision repair with patch augmentation if possible. When anatomic revision is not viable, but muscle is retained, consider partial repair with interposition bridging. Isolated, irreparable supraspinatus tears may benefit from superior capsule reconstruction. Tendon transfer is suitable for patients with significant atrophy and multiple irreparable cuff tears. Low-demand elderly patients or those with substantial glenohumeral arthritis may consider reverse total shoulder arthroplasty if conservative management fails. There are a variety of reported outcomes in the literature but long-term studies with larger cohorts are needed to improve the management of failed rotator cuff repair.

Abstract
Background While massive and irreparable rotator cuff tears (MIRCTs) have been abundantly studied, inconsistent definitions in the literature and theories about pain and dysfunction related to them can be difficult to navigate when considering an individual patient. Purpose To review the current literature for definitions and critical concepts that drive decision-making for MIRCTs. Study Design Narrative review. Methods A search of the PubMed database was performed to conduct a comprehensive literature review on MIRCTs. A total of 97 studies were included. Results Recent literature reflects added attention to clarifying the definitions of "massive, "irreparable," and "pseudoparalysis." In addition, numerous recent studies have added to the understanding of what generates pain and dysfunction from this condition and have reported on new techniques for addressing them. Conclusion The current literature provides a nuanced set of definitions and conceptual foundations on MIRCTs. These can be used to better define these complex conditions in patients when comparing current surgical techniques to address MIRCTs, as well as when interpreting the results of new techniques. While the number of effective treatment options has increased, high-quality and comparative evidence on treatments for MIRCTs is lacking.

Biomechanical comparison of combined latissimus dorsi and teres major tendon transfer vs. latissimus dorsi tendon transfer in shoulders with irreparable anterosuperior rotator cuff tears. J Shoulder Elbow Surg 2023; 32:703-712. [PMID: 36529382 DOI: 10.1016/j.jse.2022.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 10/26/2022] [Accepted: 11/10/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Irreparable anterosuperior rotator cuff tears (IASRCTs) can result in a gradual loss of active elevation and internal rotation, superior and anterior translation of the humeral head, and cuff tear arthropathy. Joint-preserving treatment options for IASRCTs in young and high-demand elderly patients remain a subject of ongoing debate. The aim of the study was to evaluate the biomechanical efficacy of the combined latissimus dorsi and teres major tendon (LDTM) transfer and compare it to an isolated latissimus dorsi (LD) transfer in a cadaveric IASRCT model. METHODS Eight cadaveric shoulders (mean age, 68.3 ± 5.2 years; range 58-71) were tested with a custom shoulder testing system. All specimens were tested at 0°, 30°, and 60° of glenohumeral abduction in the scapular plane under 4 conditions: (1) intact, (2) IASRCT, (3) combined LDTM transfer, and (4) isolated LD transfer. The superior and anteroinferior translation and subacromial contact pressure were measured. The effects of 3 different LD and LDTM muscle loading conditions were investigated to determine the effectiveness of the muscle transfer conditions. A linear mixed effect model was used for statistical analysis, followed by a Tukey post hoc test. RESULTS IASRCTs significantly increased superior translation, anteroinferior translation, and subacromial peak contact pressure. Combined LDTM transfer significantly decreased superior and anteroinferior translation compared with IASRCTs in all positions and muscle loadings. Isolated LD transfer did not significantly decrease superior (P > .115) and anteroinferior translation (P > .151) compared to IASRCT at any abduction and muscle loads except superior translation at 60° abduction and 90° of external rotation (ER) (P < .036). LDTM transfer also significantly decreased peak contact pressure from the IASRCT condition at every abduction angle (P < .046). However, isolated LD transfer significantly decreased subacromial peak contact pressure only at 30° abduction and 0° and 30° of ER with triple loading (P < .048), as well as at 60° abduction and 90° of ER (P < .003). CONCLUSIONS Combined LDTM transfer decreased superior translation, anteroinferior translation, and subacromial contact pressure compared with the IASRCT condition. Isolated LD transfer did not improve glenohumeral translation and subacromial contact pressure. Combined LDTM transfer may be a more reliable treatment option than isolated LD transfer in patients with an IASRCT.

Abstract
INTRODUCTION Latissimus dorsi and teres major (LDTM) tendon transfer has demonstrated better clinical outcomes compared to Latissimus dorsi (LD) transfer for irreparable anterosuperior cuff (subscapularis/supraspinatus) tears; however, the biomechanical effects of these procedures are unknown. Therefore, the objective of this study was to compare kinematics and internal rotation of LDTM transfer to LD transfer for anterosuperior cuff tear. METHODS Eight cadaveric shoulders were tested in four conditions; (1) intact, (2) anterosuperior rotator cuff tear, (3) LDTM transfer, and (4) LD transfer. Glenohumeral kinematics and internal rotation at 0°, 30°, and 60° of glenohumeral abduction in the scapular plane were measured. Muscle loading was applied based on physiological cross-sectional area ratios with three muscle loading conditions to simulate potentially increased tension due to the advanced insertion site of the transferred tendons. RESULTS The anterosuperior rotator cuff tear leads to a significant superior shift of the humeral head compared to intact at 0° and 30° abduction (p < 0.039). Both the LDTM (p < 0.047) and LD transfers (p < 0.032) significantly shifted the humeral head inferiorly compared to the tear condition.; however, the LDTM transfer shifted the head in the anteroinferior direction compared to the LD transfer at 60° abduction and 30° ER (p < 0.045). Both LDTM and LD transfer significantly increased internal resting rotation (p < 0.008) and maximum internal rotation (p < 0.008) compared to anterosuperior rotator cuff tear and intact at 30° and 60° abduction. LDTM transfer resulted in a significant internal resting rotation compared with the LD transfer at 30° abduction with double muscle loading (p = 0.02). At 0° abduction, the LDTM transfer (p < 0.027) significantly increased maximum internal rotation compared to anterosuperior rotator cuff tear and intact. CONCLUSION Although both LDTM and LD tendon transfer improved the abnormal humeral head apex position and internal rotation compared with the tear condition, the LDTM transfer was biomechanically superior to the LD transfer in a cadaveric model.

Abstract
BACKGROUND Irreparable anterosuperior rotator cuff tears (IASRCTs) can result in loss of active elevation, loss of internal rotation, and pseudoparalysis. Joint-preserving treatment options for IASRCTs in young and high-demand elderly patients are limited. The purpose of this study was to evaluate the clinical and radiologic outcomes of combined anterior latissimus dorsi and teres major (aLDTM) tendon transfer in patients with IASRCTs without reconstruction of the superior rotator cuff and capsular portion. METHODS This retrospective study was conducted between 2015 and 2018. We included patients who underwent combined aLDTM tendon transfer for IASRCTs. Clinical outcomes included visual analog scale for pain, Constant score, American Shoulder and Elbow Surgeons score, University of California Los Angeles shoulder scores, activities of daily living requiring active internal rotation score, active range of motion, subscapularis-specific physical examination, and rate of return to work. Radiographic analyses included the assessment of acromiohumeral distance, Hamada grade for cuff tear arthropathy, rate of anterior glenohumeral subluxation reduction, and transferred tendon integrity at 2 years postoperatively. RESULTS The mean follow-up period was 38.1 ± 13.7 (range: 24-63) months. Of the patients, 30 (mean age: 64.1 years) met the study criteria. Postoperatively, mean Constant, American Shoulder and Elbow Surgeons, University of California Los Angeles, and activities of daily living requiring active internal rotation scores improved from 47.4 to 69.9 (P < .001), 44.9 to 79.2 (P < .001), 20.0 to 28.7 (P < .001), and 13.2 to 26.9 (P < .001), respectively. The mean active range of motion was significantly increased postoperatively for both forward elevation (P < .001) and internal rotation at the back (P < .001). Of the patients, 24 (83%) returned to their previous work. No significant progression of cuff tear arthropathy was observed at final follow-up (Hamada grade: preoperative 1.3 ± 0.5 to postoperative 1.5 ± 0.7; p=0.155). Fifteen of 30 patients (50%) restored the anterior glenohumeral subluxation that was apparent preoperatively. One patient presented with transient axillary nerve palsy after surgery. Two patients presented with partial nonretracted tears of the transferred tendon. CONCLUSION This minimum 2-year follow-up study demonstrated that combined aLDTM tendon transfer without reconstruction of the superior rotator cuff and capsular portion was a viable treatment option with favorable clinical and radiologic outcomes for patients with IASRCTs.

Abstract
Background Management of combined persistent anterior glenoid bone deficiency with irreparable subscapularis tear can be very complicated and challenging especially if associated with arthritis. The objective of this study was to report the outcome of combined reconstruction of the anterior glenoid with bone autograft or allograft with additional anterior latissimus transfer to reconstruct irreparable subscapularis tear with or without humeral head replacement. Methods Nineteen patients (average age 29 years old) who underwent open anterior glenoid bone reconstruction with iliac crest bone autograft or ostechondral bone allograft (distal tibia or glenoid allograft), with anterior latissimus transfer to reconstruct irreparable subscapularis tear with or without humeral head replacement were included in this study. Outcome measures included preoperative and postoperative pain score, visual analog scale, Subjective Shoulder Value, American Shoulder and Elbow Surgeons score, and Constant Score. Results Out of the 19 patients, 5 patients underwent humeral resurfacing arthroplasty. Anterior glenoid bone reconstruction was performed with iliac crest bone autograft in 8 patients, glenoid osteochondral allograft in 7 patients, and tibial plafond in 4 patients. At mean 31-month follow-up of (13-63 months), 15 patients (79%) considered their shoulder stable and were able to return to their work and 14 (74%) patients returned to their sport activity. Redislocation had occurred in 1 of the 18 shoulders (5%), subluxation had occurred in 3 patients (16%) of the shoulders and apprehension was reported for 4 patients, 21% of the operated shoulders. All outcome measures showed significant improvement compared to before surgery. No intraoperative or immediate postoperative complications were observed. Four patients (21%) had to be revised to reverse shoulder arthroplasty. Conclusion The combination of anterior latissimus transfer, anterior glenoid bone grafting with or without humeral head resurfacing is an effective salvage surgical reconstruction that can stabilize shoulders in the setting of recurrent anterior instability after a failed Latarjet with an irreparable subscapularis tear. This could be a potential alternative reconstruction option that might be offered to patients with this difficult problem. Long-term outcome is needed to better evaluate the validity of this technique.

Management of Subscapularis Insufficiency After Total Shoulder Arthroplasty. J Am Acad Orthop Surg 2022; 30:933-940.

Abstract
The functional success of anatomic total shoulder arthroplasty (TSA) relies heavily on the healing integrity of the subscapularis tendon. Access to the glenohumeral joint is performed through a deltopectoral approach, and takedown of the subscapularis tendon is necessary in most surgeons' hands. Although initially described as a tenotomy, lesser tuberosity osteotomy and subscapularis peel are two techniques more commonly used today. Both of these options offer good results as long as proper repair is done. A subscapularis-sparing approach has more recently been advocated but is technically demanding. Failure of tendon repair can lead to early failure of anatomic total shoulder arthroplasty with accelerated glenoid loosening, decreased function, and anterior instability. Treatment options for subscapularis insufficiency include nonsurgical management, revision tendon repair, tendon reconstruction or transfer, or conversion to reverse shoulder arthroplasty. As shoulder arthroplasty continues to become increasingly prevalent, subscapularis insufficiency, too, will become more common. Accordingly, a surgeon's knowledge of subscapularis management in an arthroplasty setting must encompass treatment options for postoperative subscapularis insufficiency.

Abstract
BACKGROUND Latissimus dorsi transfer (LDT) and pectoralis major transfer (PMT) were developed to treat an irreparable subscapularis tendon tear (ISScT); however, the difference in their outcomes remains unclear. PURPOSE To systematically review and compare the outcomes of LDT and PMT for ISScT. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS A systematic review was performed through a comprehensive search of Embase, PubMed, and the Cochrane Library. Studies of LDT or PMT were included according to the inclusion and exclusion criteria. The primary outcome was the Constant-Murley score (CMS) at the final follow-up. Secondary outcomes included the subjective shoulder value (SSV), visual analog scale (VAS) score for pain, active shoulder range of motion, and the belly-press and lift-off tests. Postoperative failure and complication rates were the safety outcome measures. Outcomes were summarized into the LDT and PMT groups, and results were compared statistically (P < .05). RESULTS Twelve studies were included in this review: 184 shoulders from 9 studies for the PMT group and 85 shoulders from 3 studies for the LDT group. For the PMT and LDT groups, the mean ages were 58.9 and 55.1 years, respectively, and the mean follow-up was 66.9 and 17.4 months, respectively. Overall, the LDT and PMT groups improved in the primary outcome (CMS) and secondary outcomes (SSV, VAS, ROM, and belly-press and lift-off tests), with low rates of failure and complication. When compared with the PMT group, the LDT group showed more significant improvements in CMS (35.2 vs 24.7; P < .001), active forward flexion (44.3° vs 14.7°; P < .001), abduction (35.0° vs 17.6°; P < .002), and positive belly-press test rate (45% vs 27%; P < .001). No statistically significant difference was seen between the groups in postoperative failure rate, complication rate, mean improvement of active internal rotation, VAS, or SSV. CONCLUSION In general, LDT showed significantly better clinical outcomes postoperatively than did PMT. The available fair-quality evidence suggested that LDT might be a better choice for ISScT. Further evaluations on the relative benefits of the 2 surgical approaches are required, with more high-quality randomized controlled studies.

Abstract
BACKGROUND Reverse shoulder arthroplasty (RSA) for irreparable massive rotator cuff tear (mRCT) and cuff tear arthropathy (CTA) demonstrates satisfactory clinical outcomes. However, many studies have reported no significant improvements in internal and external rotation. To our knowledge, there have been no studies on new attempts to restore active internal rotation following RSA. The purpose of this study was to compare RSA alone and RSA with anterior latissimus dorsi and teres major (aLDTM) tendon transfer in patients with CTA and mRCT with combined loss of active elevation and internal rotation (CLEIR). METHODS This retrospective cohort study included patients who underwent RSA with a lateralized design and had CLEIR between October 2014 and January 2019. Two groups were classified: patients who underwent RSA alone (group R, n = 36) and patients who underwent RSA with aLDTM tendon transfer (group T, n = 24). Clinical outcomes, including the visual analog scale score, Constant score, American Shoulder and Elbow Surgeons score, active range of motion, score for activities of daily living requiring active internal rotation (ADLIR), and ability to perform toileting activity, were compared. Moreover, radiologic outcomes and complications were compared. RESULTS The mean follow-up period was 36.8 ± 11.6 months (range, 24-67 months). Both group R and group T showed significant improvements in clinical scores and active range of motion preoperatively and postoperatively. In group T, the Constant score (65.2 ± 7.5 vs. 58.1 ± 12.3, P = .008), ADLIR score (26.1 ± 3.1 vs. 20.3 ± 5.0, P < .001), internal rotation level with the arm behind the back (P < .001), and subscapularis-specific physical examination findings (P < .001) were significantly better than in group R. However, no significant difference in the American Shoulder and Elbow Surgeons score, forward flexion, and external rotation at 0° and 90° of abduction were found at final follow-up. Transient axillary nerve palsy was found in 2 patients in group T. However, there were no significant differences in complication rates between 2 groups. CONCLUSION Lateralized RSA with aLDTM tendon transfer for patients with CTA and mRCT with CLEIR restored shoulder function and improved clinical outcomes, especially the ability to perform ADLIR and toileting activity.

Abstract
Subscapularis tears occur more commonly than previously reported. Owing to the importance of the subscapularis in shoulder function, strong consideration should be given to repairing a full-thickness subscapularis tear when present. Historically, subscapularis repairs were done through a deltopectoral approach with good results. More recently, arthroscopic techniques have been developed with similar outcomes. When tears of the subscapularis are irreparable, reconstructive options, including tendon transfers, capsular reconstruction, and reverse shoulder arthroplasty, exist and continue to evolve.

Abstract
➤ Muscle tendon transfers (MTTs) are effective surgical procedures for reducing pain and for improving active shoulder range of motion and patient-reported outcomes for a wide range of pathologies, including serratus anterior and trapezius muscle palsy, irreparable subscapularis tears, irreparable posterosuperior rotator cuff tears, irreparable posterior rotator cuff tears in the setting of reverse shoulder arthroplasty, and symptomatic complete deltoid deficiency. ➤ The principles of MTT include ensuring that the transferred muscle is expendable, the muscle tendon unit has similar excursion, the line of pull of the transferred tendon and of the recipient muscle are similar in terms of biomechanical force, and the transferred muscle should replace at least 1 grade of strength of the deficient recipient muscle. ➤ When MTT procedures are considered, patients must have exhausted all nonoperative management, have preserved passive range of motion, and have an understanding of the postoperative expectations and potential complications. ➤ For patients with scapulothoracic abnormal motion (STAM) due to long thoracic nerve palsy, the indirect or direct pectoralis major tendon transfer is an effective procedure for reducing pain and improving active forward elevation. For patients with STAM due to spinal accessory nerve palsy, the Eden-Lange or the triple tendon transfer procedures reduce pain and improve active forward elevation and abduction as well as patient-reported clinical outcomes. ➤ Both pectoralis major and latissimus dorsi transfer procedures for isolated irreparable subscapularis deficiency without anterosuperior humeral head escape result in improvement with respect to pain, patient-reported outcomes, and forward elevation, with the pectoralis major tendon transfer demonstrating durable long-term outcomes. ➤ The latissimus dorsi or lower trapezius tendon transfer procedures for irreparable posterosuperior rotator cuff tears reliably improve patient-reported outcomes, forward elevation, abduction, and external rotation range of motion. Additionally, latissimus dorsi transfer with or without teres major transfer can be used to restore active external rotation, both in the native shoulder and in the setting of reverse shoulder arthroplasty. ➤ The complications of MTTs include infection, hematoma, and failure of tendon transfer healing; therefore, it is recommended that these complex procedures be performed by shoulder surgeons with appropriate training.

Abstract
Latissimus dorsi (LD) transfer is a reliable treatment option for irreparable posterosuperior (PS) rotator cuff tears in young and active patients that need to recover the range of motion for their daily living activities. The technique starts with an arthroscopic assessment of the tear. The next step is the mini-open stage for muscle release from the subcutaneous layer of the skin, the teres major (TM), the triceps, and the lateral border and inferior angle of the scapula. Later, the scope is used to prepare the footprint (arthroscopy) and for the release and the harvest of the tendon (endoscopy), taking care not to detach the TM and not to damage the radial nerve. A grasper is used to push the LD to its correct path medial to the triceps. After that the same instrument is placed from the anterolateral and the anterior arthroscopic portals toward the mini-open incision to catch the sutures previously loaded on the LD tendon with Krackow stitches. The LD is transferred to the greater tuberosity and is attached with one medial and one lateral knotless anchors. A third point of fixation enables a partial RC repair and ensures a surface of bone to tendon healing.

Abstract
BACKGROUND Irreparable subscapularis (SSc) tears alter the dynamic force coupling of the shoulder, resulting in pain, weakness, and impaired shoulder function. Pectoralis major (Pma), pectoralis minor (Pmi), and latissimus dorsi (LD) transfers are treatment options for irreparable SSc tears, but clinical outcomes vary. The purpose of this study was to compare the biomechanical properties of Pma, Pmi, and LD transfers in an SSc-deficient shoulder using a computational model. METHODS A computer shoulder model was used to investigate the moment arms of Pma, Pmi, and LD tendon transfers compared with an intact SSc. Nine computed tomography scans from subjects without osteoarthritis were used. Virtual Pma, Pmi, and LD transfers were performed to the upper border of the SSc insertion site on the lesser tuberosity of the humerus. Muscle moment arms were computed for functional motions of 0°-80° of internal rotation with the arm in 20° and 90° of shoulder abduction and 0°-150° of shoulder abduction. The results were compared with those of the native SSc moment arms. A repeated-measures analysis of variance was then performed to determine significant differences. RESULTS Internal rotation moment arms of the transferred Pma and Pmi decreased significantly after 30° and 40° of internal rotation compared with the SSc moment arm of the intact shoulder, whereas the moment arm of LD transfer more closely mimicked that of the native SSc through 0°-80° of internal rotation. All 3 tendon transfer configurations demonstrated weak abductive moment arms (7.6-8.0 mm), comparable to the intact SSc (7.8 mm) but significantly lower than the intact adductive moment arms of the native Pma and LD (26.8 mm and 28.2 mm, respectively). CONCLUSION LD transfer most closely approximates the native SS regarding internal rotation moment arms. However, LD transfer also showed a reduction in adductive moment arms.

Abstract
Objectives: To explore the indications and surgical techniques for arthroscopic lower trapezius transfer (LTT) with tendon autograft in managing massive irreparable posterosuperior rotator cuff tears (PSRCTs); to validate the feasibility, safety, and efficacy of this technique. Methods: This study retrospectively enrolled 23 patients with massive irreparable PSRCTs, admitted to and followed up by the Taizhou Hospital of Zhejiang province between July 2020 and April 2021, and treated with ipsilateral LTT and ipsilateral hamstring tendon autograft. The control group consisted of 23 patients with massive RCTs receiving conventional repair procedures within the same frame. Follow-up data at the preoperative visit, and postoperative month 3 were collected to assess the active range of motion, Constant–Murley Score (CMS),American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES), University of California, Los Angeles (UCLA)shoulder score, visual analog scale (VAS)and the post-operative MRI results, all of which could provide a comprehensive postoperative early efficacy assessment. Results: Three months follow-up visits were completed for all patients, revealing improvements in all aspects compared to the preoperative state, with no complications, such as postoperative infection of surgical sites and nerve injuries of infection and nerve injury. The distribution of active shoulder range of motion of patients and function scores with two types of operation was as follow: angles of flexion and lifting (130.00° ± 31.55° vs. 90.78° ± 19.85°), abduction (123.26° ± 30.47°vs. 85.87° ± 18.74°), external rotation at side (101.74° ± 14.74° vs. 91.74° ± 11.92°), external rotation at 90° abduction (41.52° ± 21.97° vs. 24.57° ±12.60°), VAS (0.74± 0.81 vs. 1.87 ±0.87), CMS(56.3 ± 13.01 vs. 48.30 ± 8.38), UCLA shoulder score (24.04 ± 2.88 vs.20.96 ± 3.47), ASES (72.91 ± 9.99 vs.60.74 ± 8.84). Significantly better improvements were found in the study group on month 3.19 of 23 patients in the study group and 17 of 23 patients in the control group underwent MRI on the 3 months follow up. Retear was found in only one patient who had grade 4 subscapularis tendon injury, However, revision was not performed due to postoperative pain relief and functional improvement. Conclusion: Compared to conventional repair procedures, in the early postoperative period, LTT with tendon autograft could achieve better pain relief, more rapid motor functional recovery, and higher functional scores for massive irreparable PSRCTs.

Abstract
Background Previously reported outcomes after tendon transfers to reconstruct the subscapularis are unpredictable and often unsatisfactory, especially in the presence of anterior humeral head subluxation. We studied the anatomic feasibility of the lower trapezius and the rhomboid minor transfer to reconstruct irreparable tendon tears of the subscapularis. The aim of this study was to determine the feasibility of lower trapezius and rhomboid minor transfer to reconstruct irreparable subscapularis tendon tears. Materials and methods We measured the tendons dimensions, muscles excursions, distances to pedicles, and dissection needed to complete a successful lower trapezius and/or rhomboid minor transfer to the subscapularis footprint in 10 cadaveric shoulders. The transferred muscles were detached distally, augmented with a semitendinosus and gracilis autograft, and passed anteriorly between the scapula and the subscapularis remnant through a small serratus window to reach the lesser tuberosity. The risk of pedicle compression was subjectively assessed in all cases. Results The trapezius and rhomboid tendons were asymmetric with an average length of 37.6 mm and 21.7 mm, an average width of 63 mm and 33.4 mm, respectively. The mean distances from each distal insertion to the lesser tuberosity were 109 mm for the trapezius and 144 mm for the rhomboid. Mean distances from tendon to pedicle were 57.9 mm and 33.1 mm, respectively. The mean size of the necessary serratus window was 49.4 mm, which was measured at maximal excursion achieved at maximal external rotation 90° representing two digitations. All of the tendon transfers were feasible, and the risk of pedicle compression was 20% for the trapezius and 10% for the rhomboid. Superior migration of the transfer was observed during passive external rotation if the insertion point was too high. Conclusions Transfer of the lower trapezius and rhomboid minor to the lesser tuberosity to reconstruct an irreparable subscapularis tear is feasible without extensive dissection and with a low risk of nerve compression. We recommend not to transfer the rhomboid minor routinely, owing to the risk of tendon luxation after external rotation of the shoulder.

Abstract
Symptomatic irreparable rotator cuff tears pose a challenge for shoulder surgeons. Whilst reverse polarity shoulder arthroplasty is an effective option for older symptomatic patients who have exhausted conservative management, the optimal treatment for younger patients remains controversial. In this article we outline the main tendon transfer options, including anatomical considerations, indications, contraindications, surgical technique, complications and a review of the evidence. Tendon transfers provide an alternative joint-preserving surgical option, but the evidence so far is limited, with a clear need for well-designed comparative studies to confirm their effectiveness.

Werthel JD, Schoch BS, Hooke A, Sperling JW, An KN, Valenti P, Elhassan B. Biomechanical effectiveness of tendon transfers to restore active internal rotation in shoulder with deficient subscapularis with and without reverse shoulder arthroplasty. J Shoulder Elbow Surg 2021; 30:1196-1206. [PMID: 32919048 DOI: 10.1016/j.jse.2020.08.026] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 08/13/2020] [Accepted: 08/17/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Loss of active shoulder internal rotation can be very disabling. Several tendon transfers have been described for the management of an irreparable subscapularis (SSC) tear. The purpose of this study was to determine and compare the internal rotation moment arm (IRMA) of the sternal head of the pectoralis major (PM), latissimus dorsi (LD), and teres major (TM) when transferred to different insertion sites to restore shoulder internal rotation with and without reverse shoulder arthroplasty (RSA). METHODS Six fresh-frozen right hemithoraces were prepared and evaluated using a custom tendon transfer model to determine the IRMA of different tendon transfers using the tendon and joint displacement method. Five tendon-transfer pairs were modeled using a single suture and tested before and after implantation of an RSA (Comprehensive; Zimmer-Biomet, Warsaw, IN, USA): PM to the insertion site of the SSC, LD to the anterior insertion site of the supraspinatus (SSP) tendon on the greater tuberosity, LD to SSC, TM to SSP, and TM to SSC. The SSC was not repaired at the end of the RSA procedure to simulate an SSC deficiency. The PM transfer was passed under the conjoined tendon when tested on the intact shoulder and above the conjoined tendon when tested with an RSA. RESULTS Tendon transfers were shown to have a significant effect on IRMA. The effect of transferred tendons was significantly affected by the position of the humerus. With the humerus adducted, the IRMA of the TM-SSP (14.1 mm ± 3.1 mm) was significantly greater than the other transfers. With the humerus abducted to 90°, the IRMAs of the LD-SSP (30.0 mm ± 5.4 mm) and TM-SSP (28.4 mm ± 6.6 mm) were significantly greater than the IRMAs of other transfer options. The IRMA of the native shoulder differed significantly from that of the RSA state for all tendon transfers. With the humerus adducted to the side of the body, the IRMA of the RSA PM-SSC transfer was significantly greater than that without an RSA (19.0 mm ± 6.4 mm vs. 7.1 mm ± 0.9 mm), demonstrating increased efficiency for internal rotation in the RSA state. CONCLUSION Tendon transfers to restore shoulder internal rotation differ in effectiveness and may be affected by arm position and by implantation of a lateralized humerus/lateralized glenoid RSA. The LD potentially results in superior restoration of shoulder internal rotation in a native shoulder (given the risk of nerve compression with the TM transfer) compared with PM and should be considered as a potential tendon transfer to restore internal rotation in selected patients. In combination with a lateralized humerus/lateralized glenoid RSA, the fulcrum provided by the biomechanics of the semiconstrained implant allows the PM transfer to become a more efficient tendon transfer to restore active internal rotation.

Abstract
Background Understanding muscle and tendon anatomy is of tremendous importance to achieve optimal surgical execution and results in tendon transfers around the shoulder. The aim of this study was to introduce and describe an additional distal muscle slip of the teres major (TM). Methods Sixteen fresh-frozen cadaver shoulders were dissected with the deltopectoral approach. The ventral latissimus dorsi (LD) tendon was harvested, and the shoulders were analyzed for the presence/absence of a distal teres major slip (dTMs) and its dimensions and relationship with the TM and LD tendons. Results The dTMs was identified in 12 shoulders (75%). It was always distal to the TM tendon and visible during the deltopectoral approach. There was a clear separation between the TM proximally and dTMs tendon distally. At the humeral insertion, both tendons had a common epimyseal sheet around the teres major and inserted continuously at the humerus. The mean width of the dTMs tendon at the insertion was 13 ± 4 mm (range, 7–22 mm). The total lengths of the dTMs tendon and LD tendon were 40 ± 7 mm (range, 25–57 mm) and 69 ± 7 mm (range, 57–79 mm), respectively (p < 0.001). The dTMs muscle showed direct adhesions in ten shoulders (83%) with the LD muscle. Conclusions This is the first macroscopic description of an additional distal slip of the teres major muscle. The dTMs has a separate (distal) but continuous (mediolateral) insertion at the humerus within a common epimyseal sheet around the TM. The dTMs tendon is visible during the deltopectoral approach and can therefore provide a lead structure, particularly in ventral LD transfers with the deltopectoral approach.

Abstract
Several latissimus dorsi tendon transfer techniques for shoulder problems have been previously described and developed. These techniques involve the transfer in obstetric palsy, transfer in irreparable posterosuperior rotator cuff tears and subscapularis tears, and transfer in reverse shoulder arthroplasty. We detail the differences in planning and surgery and the need for different approaches. This historical and technical description provided in this study will benefit surgeons wishing to use the procedure.

Abstract
Several reconstruction techniques for irreparable tears of the subscapularis tendon have been described with variable results regarding pain relief, functional recovery, and dynamic stabilization of the glenohumeral joint. Because of a more advantageous direction of movement compared with previously described transfer techniques such as transfer of the pectoralis major and pectoralis minor tendons, the anterior latissimus dorsi (LD) transfer has been proposed as a potentially beneficial treatment method. This Technical Note aims to introduce an alternative technique for the anterior LD transfer that combines the advantages of a proper muscle release and tendon reinforcement through an axillary incision with the arthroscopic intra-articular and periarticular work, including detachment of the LD tendon from its humeral insertion and reattachment at the lesser tuberosity.

Abstract
CASE A 43-year-old man with chronic right shoulder pain and dysfunction due to recurrent anterior instability, irreparable subscapularis tear, and glenohumeral arthritis presented to our practice. After workup and counseling, he was treated with anatomic total shoulder arthroplasty augmented by anterior capsular reconstruction using human acellular dermal allograft. At 15 months postoperatively, his forward elevation, external rotation, and internal rotation were 160, 45, and T12, nearly equal to contralateral values. His glenohumeral joint remained reduced, and no complications were encountered. CONCLUSION We report the first known anterior capsular reconstruction performed in combination with anatomic shoulder arthroplasty.

Abstract
Irreparable tears of the subscapularis (SS) tendon are difficult to manage and represent a challenge for the surgeon, especially in young and active patients. They are associated with a horizontal imbalance of the shoulder, causing pain and limitation of active internal rotation. Historically, the alternative for these patients has been transfer of the pectoralis major, with all its variations, total or partial, up or under the conjoint tendon. However, this transfer has mechanical disadvantages, especially related to the vector of traction, because it originates in the anterior region of the chest. In 2013, Elhassan and colleagues demonstrated in cadavers the technical feasibility and neurological safety of performing transfers of the latissimus dorsi (LD) to the lesser tuberosity to reconstruct irreparable lesions of the subscapularis. This option, compared with alternatives, has superior biomechanical advantages such as a similar vector of traction, originating from lower and posterior to the thorax, in addition to involving a synergistic muscle in action. In early 2016, Kany and colleagues first published a study of 5 patients undergoing arthroscopic assisted LD to SS transfer, with promising results. Our purpose is to present an arthroscopically assisted latissimus dorsi transfer technique in patients with irreparable subscapularis rupture.

Abstract
In young patients, irreparable subscapularis tears can be managed by latissimus dorsi (LD) transfer on the lesser tuberosity. We provide a technical guide for isolated LD anterior transfer. The surgical procedure begins with glenohumeral exploration and release of the remaining subscapularis. Then, we dissect the LD tendon below the subscapularis. At the upper and inferior borders, we dissect the LD from the teres major, protecting the radial nerve anteriorly and inferiorly. Next, we detach the LD. Inferiorly, we cut the aponeurotic expansion for the triceps. A Foley catheter is used as a shuttle relay, anterior to the axillary nerve and medial and posterior to the radial nerve. We continue with an open dissection of the LD, posterior to the axillary fossa, to release the LD from the skin and tip of the scapula. The LD is transferred on the lesser tuberosity after retrieved by the Foley catheter, with care taken not to twist the tendon. It is fixed with 2 lateral anchors and 1 medial anchor. A shoulder brace is worn for 6 weeks. Physiotherapy begins thereafter.

Abstract
Repairing massive rotator cuff tendon defects remains a challenge due to the high retear rate after surgical intervention. 3D printing has emerged as a promising technique that enables the fabrication of engineered tissues with heterogeneous structures and mechanical properties, as well as controllable microenvironments for tendon regeneration. In this study, we developed a new strategy for rotator cuff tendon repair by combining a 3D printed scaffold of polylactic-co-glycolic acid (PLGA) with cell-laden collagen-fibrin hydrogels. We designed and fabricated two types of scaffolds: one featuring a separate layer-by-layer structure and another with a tri-layered structure as a whole. Uniaxial tensile tests showed that both types of scaffolds had improved mechanical properties compared to single-layered PLGA scaffolds. The printed scaffold with collagen-fibrin hydrogels effectively supported the growth, proliferation, and tenogenic differentiation of human adipose-derived mesenchymal stem cells. Subcutaneous implantation of the multilayered scaffolds demonstrated their excellent in vivo biocompatibility. This study demonstrates the feasibility of 3D printing multilayered scaffolds for application in rotator cuff tendon regeneration.

Abstract
PURPOSE OF REVIEW Irreparable subscapularis tears represent a challenging entity, especially when they occur in younger patients with high functional demands. Tendon transfers are one of the options considered for surgical management for this pathology. The purpose of this article is to review the surgical technique and outcome of the two most common tendon transfers considered for irreparable subscapularis tears: pectoralis major and latissimus dorsi. RECENT FINDINGS Transfer of the pectoralis major has been considered for decades the transfer of choice for irreparable subscapularis tears. Recently, a series with long-term follow-up (over 18 years) supported the reduction in pain and improvement in functional scores and patient satisfaction after pectoralis major transfer. However, the range of motion and the force in internal rotation were not maintained over time. Transfer of the latissimus dorsi to the lesser tuberosity has been recently described as an alternative with a sound biomechanical rationale and encouraging short-term results. Transfer of the pectoralis major and the transfer of latissimus dorsi to the lesser tuberosity are the two transfers most commonly considered for patients with irreparable subscapularis tears. Transfer of the pectoralis major has a much longer track record. Both procedures seem to improve outcomes. Comparative studies are needed to determine the relative indications of these two procedures.

Abstract
BACKGROUND Anterior capsule reconstruction (ACR) and latissimus dorsi transfers (LTs) have been proposed as solutions for irreparable subscapularis tears. The purpose of this study was to biomechanically assess the effects of ACR and LT separately and together for treatment of irreparable subscapularis tears. MATERIALS AND METHOD Eight cadaveric shoulders underwent 5 testing conditions: (1) intact, (2) irreparable subscapularis tear, (3) ACR, (4) ACR+LT, and (5) LT alone. Anteroinferior translation loads of 20, 30, and 40 N were applied. Range of motion and magnitudes of glenohumeral anterior and inferior translation at 0°, 30°, and 60° of abduction and at 30° and 60° of external rotation were measured for each testing condition. RESULTS At 30° of abduction and 60° of external rotation, ACR and ACR+LT restored anterior and inferior translation to intact (P > .702) for 30 and 40 N of anteroinferiorly directed force. LT alone did not restore anteroinferior stability at 30 N of distraction force at 30° of glenohumeral abduction and 60° of external rotation (P < .001). However, ACR and ACR+LT led to significant decreases in total range of motion compared to intact at 0° and 30° of abduction (P < .007). CONCLUSIONS ACR with dermal allograft was able to restore anteroinferior stability in the setting of irreparable subscapularis tears but resulted in decreased total range of motion. LT alone was less effective than ACR in restoring glenohumeral stability. The addition of LT as a dynamic restraint did not increase the efficacy of ACR.

Abstract
Indications and techniques for tendon transfer in irreparable rotator-cuff tear have greatly progressed and are no longer restricted to external rotation deficit. The present article first reviews the various types of tear and corresponding tendon transfers and the biomechanics of the pseudoparalytic shoulder. The indication of choice for tendon transfer is iterative tear following failure of isolated long biceps tenotomy or partial repair. Latissimus dorsi, inferior trapezius and pectoralis major transfer are the 3 types to be used after failure of primary surgery. Latissimus dorsi transfer is indicated for partial loss of active limb elevation or isolated loss of internal rotation. Inferior trapezius transfer is best indicated for isolated active external rotation deficit. In pseudoparalytic shoulder with total loss of active elevation or combined loss of elevation and active external rotation, isolated transfer is insufficiently powerful to restore active range of motion and should be associated to reverse arthroplasty. We describe the various transfer techniques and report their results.

Abstract
Background This retrospective study was undertaken to evaluate mid-term clinical and radiological outcomes of lattisimus dorsi (LD) tendon transfer in patients with irreparable massive rotator cuff tears (MRCT). We hypothesize that LD tendon transfer would provide safe and satisfactory clinical outcomes at mid-term follow-up. Methods From November 2008 to December 2016, 23 patients (57.5 ± 4.4 years; 20 male, 3 female) who underwent LD tendon transfer for massive tears, were enrolled. Inclusion criteria were irreparable MRCT. Exclusion criteria included full thickness subscapularis tear, rotator cuff arthropathy, anterosuperior rotator cuff tear, and osteoarthritis. Mean follow-up period was 4.7 ± 4.0 years (range, 2–12 years). Clinical assessment (American Shoulder and Elbow Surgeons [ASES], University of California, Los Angeles [UCLA], Simple Shoulder Test [SST]) and radiographic assessment (osteoarthritis [OA], acromiohumeral distance [AHI]) were evaluated. Results ASES, UCLA and SST scores, and range of motion (ROM), except internal rotation, improved significantly at the last follow-up (p<0.05). Also, AHI was significantly improved at the last follow-up, from 6.6 mm to 8.2 mm (p=0.008). At the final follow-up, the radiologic stages of the glenohumeral osteoarthritis were determined as stage 1 in 9 patients, stage 2 in 10 patients, stage 3 in 2 patients, and stage 4 in 2 patients. Complications were observed in 21.7% cases: 3 re-tears and 2 infections were noted in our study. Conclusions LD tendon transfer for irreparable MRCT provides satisfactory clinical outcomes at mid-term follow-up. Mild degenerative osteoarthritis (stage 1, 2) of the shoulder joint are common at the mid-term follow-up. Also, complications such as tear, infection should be considered.

Arthroscopy 2019; 35:1973-1981. [PMID: 31167737 DOI: 10.1016/j.arthro.2019.01.057] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2018] [Revised: 12/26/2018] [Accepted: 01/20/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate clinical outcomes and tendon integrity in patients with chronic retracted subscapularis tears using an arthroscopic single-row oblique mattress suture repair technique. METHODS Patients with full-thickness subscapularis tears retracted to the glenoid level and with at least 2 years of follow-up were included. Tendon retraction level was measured on preoperative axial magnetic resonance images and confirmed during arthroscopic surgery. The subscapularis tendon was repaired arthroscopically using the single-row oblique mattress suture technique on the medial margin of the lesser tuberosity. Two double-loaded suture anchors were used to obtain firm fixation between the tendon and the footprint. Clinical outcomes were assessed for all patients preoperatively and postoperatively using active range of motion, a visual analog scale score for pain, and American Shoulder and Elbow Surgeons and Constant scores. To evaluate structural integrity of the repaired tendon, all patients underwent magnetic resonance imaging at 6 months and ultrasonography at 1 year after surgery. RESULTS The shoulder function of the 33 patients analyzed was improved significantly after a mean follow-up period of 26.3 ± 3.5 months compared with preoperative values (American Shoulder and Elbow Surgeons score of 52.0 ± 7.9 preoperatively vs 79.6 ± 7.0 at last follow-up, P < .001, and Constant score of 43.0 ± 13.4 preoperatively vs 76.7 ± 9.2 at last follow-up, P < .001). Postoperative active range of motion improved significantly in forward flexion, external rotation, and internal rotation (P < .001). The mean visual analog scale pain score decreased by 3.42 (5.2 ± 1.6 preoperatively vs 1.9 ± 1.4 at last follow-up, P < .001). In 4 patients (12.1%), subscapularis retears were confirmed on postoperative magnetic resonance imaging. CONCLUSIONS Despite significant retraction, arthroscopic repair using a single-row oblique mattress suture technique in patients who had chronic subscapularis tears with retraction to the glenoid level yielded satisfactory clinical outcomes and reliable tendon healing. LEVEL OF EVIDENCE Level IV, therapeutic case series.

Significant improvement in patient self-assessed comfort and function at six weeks after the smooth and move procedure for shoulders with irreparable rotator cuff tears and retained active elevation. INTERNATIONAL ORTHOPAEDICS 2019; 43:1659-1667.

Abstract
BACKGROUND It has been documented that the smooth and move procedure-smoothing the proximal humeral surface while maintaining the coracoacromial arch-can provide clinically significant long-term improvement in function for patients having irreparable rotator cuff tears with retained active elevation. This study sought to demonstrate that clinically significant gains in comfort, function, and active motion can be realized as early as 6 weeks after this procedure. METHODS We conducted a prospective cohort study of the 6-week clinical outcomes for 48 patients enrolled prior to a smooth and move procedure for irreparable rotator cuff tears. Prior rotator cuff repair had been attempted in 28 (70%). RESULTS In 40 patients with preoperative and 6-week postoperative measurements, the Simple Shoulder Test scores improved from an average of 3.4 ± 2.8 preoperatively to 5.7 ± 3.5 at 6 weeks (p < 0.001), an improvement that exceeded the published values for the minimal clinically important difference (MCID). The clinical outcomes were not worse for the 18 shoulders with irreparable tears of both the supraspinatus and infraspinatus. In 30 patients with preoperative and 6-week postoperative objective measurements of active motion, the average abduction improved from 93(± 43) to 123(± 47)° (p = 0.005) and the average flexion improved from 102(± 46) to 126(± 44)° (p = 0.023). CONCLUSIONS In addition to its previously documented long-term effectiveness for shoulders with irreparable rotator cuff tears and retained active elevation, this study demonstrates that the smooth and move procedure provides clinically significant improvement as early as 6 weeks after surgery.

Abstract
Massive, irreparable rotator cuff tears (MIRCTs) provide a significant dilemma for orthopaedic surgeons. One treatment option for MIRCTs is reverse total shoulder arthroplasty. However, other methods of treating these massive tears have been developed. A search of the current literature on nonoperative management, arthroscopic debridement, partial repair, superior capsular reconstruction (SCR), graft interposition, balloon spacer arthroplasty, trapezius transfer, and latissimus dorsi transfer for MIRCTs was performed. Studies that described each surgical technique and reported on clinical outcomes were included in this review. Arthroscopic debridement may provide pain relief by removing damaged rotator cuff tissue, but no functional repair is performed. Partial repair has been suggested as a technique to restore shoulder functionality by repairing as much of the rotator cuff tendon as possible. This technique has demonstrated improved clinical outcomes but also fails at a significantly high rate. SCR has recently gained interest as a method to prohibit superior humeral head translation and has been met with encouraging early clinical outcomes. Graft interposition bridges the gap between the retracted tendon and humerus. Balloon spacer arthroplasty has also been recently proposed and acts to prohibit humeral head migration by placing a biodegradable saline-filled spacer between the humeral head and acromion; it has been shown to provide good clinical outcomes. Both trapezius and latissimus dorsi transfer techniques involve transferring the tendon of these respective muscles to the greater tuberosity of the humerus; these 2 techniques have shown promising restoration in shoulder function, especially in a younger, active population. Arthroscopic debridement, partial repair, SCR, graft interposition, balloon spacer arthroplasty, trapezius transfer, and latissimus dorsi transfer have all been shown to improve clinical outcomes for patients presenting with MIRCTs. Randomized controlled trials are necessary for confirming the efficacy of these procedures and to determine when each is indicated based on specific patient and anatomic factors.

Abstract
The optimal approach to management of the subscapularis in total shoulder arthroplasty (TSA) is controversial. Options include the subscapularis tenotomy, lesser tuberosity osteotomy (LTO), and peel. This review provides a summary of subscapularis anatomy and function, outcomes associated with subscapularis management options in TSA, and postoperative subscapularis deficiency. Based on the available literature, LTO appears to result in improved function and subscapularis integrity relative to tenotomy, while peel and LTO have generally led to equivalent outcomes. The highest level of evidence to date is derived from a randomized controlled trial that demonstrated that outcomes following peel and LTO were not significantly different. There is currently a paucity of high-quality evidence as most studies have consisted of small retrospective series with varying outcome measures. Furthermore, the optimal approach to establishing the diagnosis of subscapularis deficiency following TSA is unclear.
