Comparable Pain Levels and Functional Outcomes With and Without the Use of Dermal Allograft Augmentation in Endoscopic Gluteus Medius Repair. Arthroscopy 2024:S0749-8063(24)00622-4. [PMID: 39209076 DOI: 10.1016/j.arthro.2024.08.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 08/15/2024] [Accepted: 08/16/2024] [Indexed: 09/04/2024]
Abstract
PURPOSE To retrospectively compare the clinical outcomes of patients undergoing endoscopic gluteal tendon repair with and without the use of dermal allograft augmentation. METHODS A retrospective review of prospectively collected data, single-surgeon cohort study was performed on all patients undergoing endoscopic gluteus medius repair (GMR) and gluteus medius repair with augmentation (GMR-A) between April 2017 and April 2022. Dermal allograft augmentation was utilized in cases where intraoperative gluteus tissue quality was poor. An electronic survey of patient-reported outcome measures (PROMs) was completed at a minimum of 1 year postoperatively. PROMs included a Visual Analogue Scale (VAS) for pain; University of California, Los Angeles (UCLA) Activity Scale; modified Harris Hip Score (mHHS); Hip Outcome Score-Sport-Specific Subscale (HOS-SSS); and a Single Assessment Numeric Evaluation (SANE). The proportion of patients achieving the minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB) for each PROM were compared between groups. RESULTS Sixty-four patients were reached for follow-up (26 GMR, 38 GMR-A). No differences were found between the groups in terms of demographics. There was a significantly longer time to follow-up in the GMR group (39.4±26.9 vs 24.2±11.7 months, p=0.003). There were no differences between the GMR and GMR-A groups in terms of postoperative PROMs including VAS (3.3±2.6 vs 3.3±2.8, p=0.99), UCLA (5.8±2.1 vs 5.1±2.0, p=0.17), mHHS (70.1±18.1 vs 68.9±17.8, p=0.80), HOS-SSS (67.7±28.9 vs 62.5±30.2, p=0.50), and SANE (71.7±27.9 vs 71.3±22.8, p=0.95). A significantly greater proportion of patients in the GMR group achieved a PASS for UCLA (64% vs. 34%, p=0.02). One patient each in the GMR (3.8%) and GMR-A (2.6%) groups underwent revision gluteus medius repair with dermal allograft augmentation at the final follow-up. CONCLUSIONS Our study demonstrates comparable clinical outcomes with and without the use of dermal allograft augmentation in endoscopic gluteus medius repairs. LEVEL OF EVIDENCE III, retrospective comparative series.

Abstract
PURPOSE To assess the consistency and quality of risk factor reporting for rotator cuff repair (RCR) retear and identify risk factors most frequently associated with retear. METHODS A systematic review was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Of the initial 3,158 studies, a total of 31 met the following inclusion criteria: (1) clinical studies regarding RCR failure, (2) arthroscopic procedures involving RCR, (3) reporting of clinical outcomes, (4) publication within the past 5 years, and (5) studies investigating preoperative risk factors for retear. After full-text review, 18 risk factors were analyzed. RESULTS The most consistently significant risk factors were acromiohumeral distance (80%), critical shoulder angle (67%), tear size (63%), anterior-posterior dimension (60%), fatty infiltration (FI) (58%), and retraction size (56%). FI was analyzed using different methods among studies, with 63% finding significant results and 50% of all studies performing ordinal analysis. Tear size was inconsistently analyzed quantitatively or qualitatively, with 58% of studies finding significant results and 63% of all studies performing quantitative analysis. Risk factors consistently found to be nonsignificant included age, sex, diabetes mellitus, symptom duration, hand dominance, repair technique, smoking, and body mass index. CONCLUSIONS Tear size, FI, and retraction size were found to be significant risk factors in most of the included studies evaluating rotator cuff retear. Risk factors less likely reported as predictive included repair technique, age, sex, diabetes mellitus, symptom duration, hand dominance, repair technique, smoking, and body mass index. Risk factors that require further investigation include critical shoulder angle, acromiohumeral distance, and anterior-posterior tear dimension. LEVEL OF EVIDENCE Level III, systematic review of Level III-IV studies.

Abstract
Background The purpose of this study was to evaluate and compare the clinical and structural outcomes after arthroscopic repair of isolated supraspinatus tears in patients older than 70 years vs. patients younger than 50 years to determine whether age influences the treatment of these tears. Methods We conducted a retrospective, comparative study of 87 shoulders of 86 patients older than 70 years who underwent rotator cuff repair after isolated full-thickness supraspinatus tear between January 2010 and December 2020. A control group of 87 patients younger than 50 years was matched for sex, body mass index, smoking habits, tendon retraction according to Patte and fatty infiltration according to Goutallier. Clinical assessment used Constant-Murley Score (CMS), age- and sex-matched Constant Scores and Subjective Shoulder Value at 6 months. Cuff integrity was evaluated using ultrasonography based on the Sugaya criteria, types I-II-III being considered as healed. Results The CMS significantly improved by +17.91 points in elderly patients compared with +7.47 points in controls (P < .1) and activity (P = .2), mobility (P < .1), and strength (P < .1). The adjusted CMS significantly improved by +24.94 in elderly patients compared with +8.49 points in controls (P < .1). The Subjective Shoulder Value improved by +29.48 points in elderly patients compared with +23.47 points in controls. The improvement was similar in both groups. (P < .10). Satisfaction was similar in both groups (P = .31). Regarding structural outcomes, patients younger than 50 years presented better results in terms of healing than patients older than 70 years, as the healing rate was 73.7% in the elderly group and 88.5% in the control group (P = .1). The clinical outcomes were not significantly associated with the tendon healing (P = .1). Conclusion Functional gain for patients older than 70 years is better than their younger peers despite their low-grade healing. Arthroscopic repair after isolated supraspinatus tears should be considered as a valuable treatment regardless the age.

Abstract
BACKGROUND Previous research has emphasized the effect of prognostic factors on arthroscopic rotator cuff repair (ARCR) success, but a specific focus on subscapularis (SSC) tendon repair healing is lacking. PURPOSE To identify prognostic factors for SSC healing after ARCR and develop the Subscapularis Healing Index (SSC-HI) by incorporating these factors. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This was a retrospective study using prospectively maintained data collected from patients with isolated or combined SSC tears who underwent ARCR between 2011 and 2021 at a single institution with a minimum 2-year follow-up. Functional outcomes were assessed using the American Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Value (SSV), and visual analog scale (VAS) pain scale. SSC tendon healing was evaluated via ultrasound at the final follow-up. Multivariate logistic regression analysis was performed to determine the factors affecting SSC healing, and based on these factors, the SSC-HI, which ranges from 0 to 15 points, was developed using odds ratios (ORs). RESULTS Among 1018 ARCR patients, 931 met the inclusion criteria; 279 returned voluntarily for postoperative SSC ultrasound assessment. The overall healing failure rate was 10.8% (30/279). Risk factors for healing failure included female sex (P = .008; OR, 3.119), body mass index (BMI) ≥30 (P = .053; OR, 2.323), supraspinatus fatty infiltration ≥3 (P = .033; OR, 3.211), lower SSC fatty infiltration ≥2 (P = .037; OR, 3.608), and Lafosse classification ≥3 (P = .007; OR, 3.224). A 15-point scoring system comprised the following: 3 points for female sex, 2 points for BMI ≥30, 3 points for supraspinatus fatty infiltration ≥3, 4 points for lower SSC fatty infiltration ≥2, and 3 points for Lafosse classification ≥3. Patients with ≤4 points had a 4% healing failure rate, while those with ≥9 points had a 55% rate of healing failure. Patients with a healed SSC reported significantly higher ASES (healed SSC: ΔASES, 44.7; unhealed SSC: ΔASES, 29; P < .01) and SSV (healed SSC: ΔSSV, 52.9; unhealed SSC: ΔSSV, 27.5; P < .01) and lower VAS (healed SSC: ΔVAS, -4.2; unhealed SSC: ΔVAS, -3; P < .01) scores compared with those with an unhealed SSC. CONCLUSION The SSC-HI scoring system integrates clinical and radiological factors to predict SSC healing after surgical repair. Successful SSC healing was found to be associated with enhanced functional outcomes, underscoring the clinical relevance of SSC healing prediction in the management of these tears.

Abstract
Loss of shoulder function can be a complex condition to manage. Specifically, the definition between the terms pseudoparalysis and pseudoparesis remains inconsistent in the literature based on various factors including chronicity, present pathology, and the role of pain in the loss of function. There is also debate as to the optimal management strategies for these challenging conditions. In the setting of advanced glenohumeral arthritis or arthropathy in the correct patient, arthroplasty provides consistent and reliable results. However, in younger patients or the patient without arthritis, arthroplasty may not be the best option. In some cases, addressing pain with biceps procedures, balloon spacer placement, débridement, or others may be appropriate. However, other instances may require attempts at improving shoulder kinematics with procedures such as rotator cuff repair, superior capsular reconstruction, and tendon transfer. In this review, we discuss current definitions for pseudoparalysis and pseudoparesis, in addition to reviewing the indications for the various treatment options and their respective outcomes.

J Orthop Surg Res 2024; 19:368. [PMID: 38902793 PMCID: PMC11191288 DOI: 10.1186/s13018-024-04858-x] [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: 04/14/2024] [Accepted: 06/15/2024] [Indexed: 06/22/2024] Open
Abstract
BACKGROUND The effects of the timing of surgical repair on the outcomes of traumatic and non-traumatic rotator cuff injuries (RCI) remain elusive. Thus, this study aimed to compare differences in outcomes following the repair of traumatic and non-traumatic RCI at varying time points. METHODS The study population comprised 87 patients with traumatic and non-traumatic RCI who underwent arthroscopic rotator cuff repair and were followed up for a minimum of 6 months. Next, the trauma and the non-trauma groups were stratified into subgroups according to the time of injury (early repair: occurring within 3 months; delayed repair: occurring after 3 months). Measurements before and after surgical interventions were compared to evaluate the effect of the duration of RCI on the functional status of patients in the trauma and non-trauma groups. Primary evaluation indices included the Visual Analog Scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, Constant shoulder function score, and the University of California, Los Angeles (UCLA) shoulder score. Secondary evaluation indices consisted of shoulder range of motion (ROM), postoperative rotator cuff retear rate, and incidence of joint stiffness. RESULTS Among the 40 patients in the trauma group, 22 underwent early repair, whereas the remaining 18 underwent delayed repair. In the non-trauma group consisting of 47 patients, 18 underwent early repair, whereas the remaining 29 underwent delayed repair. The minimum clinical follow-up time was 6 months, with an average follow-up time of 10.2 months. During postoperative follow-up, 1 and 6 patients who underwent early and delayed repair experienced re-tear in the trauma group, respectively. Contrastingly, 3 and 8 patients who underwent early and delayed repair presented with re-tear in the non-trauma group, respectively. CONCLUSION Early repair of traumatic RCI yielded superior outcomes, including improved range of motion, lower pain symptoms, and lower risk of postoperative re-tears compared to delayed repair. Additionally, non-surgical treatment is recommended as the preferred approach for patients with non-traumatic RCI.

Massive Irreparable Rotator Cuff Tears Treated With a Tuberoplasty Yield Favorable Clinical Outcomes With Variable Rates of Complications: A Systematic Review. Arthroscopy 2024; 40:1897-1905. [PMID: 38278459 DOI: 10.1016/j.arthro.2023.11.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/15/2023] [Accepted: 11/19/2023] [Indexed: 01/28/2024]
Abstract
PURPOSE To systematically review the patient-reported outcomes and postoperative complications following tuberoplasty for the treatment of massive irreparable rotator cuff tears. METHODS A literature search was conducted using PubMed and EMBASE computerized databases from database inception to June 2023 in accordance with the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Included studies evaluated clinical outcomes, postoperative complications, and reoperation rates following tuberoplasty for the treatment of massive irreparable rotator cuff tears. Exclusion criteria consisted of non-English language, cadaveric studies, case reports, animal studies, studies with overlapping cohorts, letters to editors, and review articles. Study quality was assessed using the Methodological Index for Non-Randomized Studies criteria. Clinical outcome scores included the visual analog scale for pain, University of California Los Angeles score, and Constant score. RESULTS Seven studies from 2002 to 2023 consisting of 123 patients with a mean age of 66.5 years (mean range, 63-70.4 years) were included. The mean follow-up time ranged from 18 to 98 months. The mean Methodological Index for Non-Randomized Studies score was 13.5 (range, 13-15). At final follow-up, the mean postoperative visual analog scale pain scores ranged from 2.3 to 2.5, University of California-Los Angeles shoulder score from 27.2 to 27.7, and Constant scores from 59.2 to 90.6. Postoperative active forward flexion and abduction ranged from 131° to 165°, and 123° to 160°, respectively. The change in acromiohumeral distance postoperatively ranged from -1 mm to -0.6 mm. The rate of postoperative complications ranged from 0% to 19% of patients, while 0% to 19% of patients underwent revision surgery to reverse shoulder arthroplasty. CONCLUSIONS Tuberoplasty for the treatment of massive irreparable rotator cuff tears results in good clinical outcomes with significant pain relief in select populations. However, the variable reoperation rates should be considered when counseling patients. LEVEL OF EVIDENCE Level IV, systematic review of Level IV studies.

Semi-automatic proximal humeral trabecular bone density assessment tool: technique application and clinical validation. Osteoporos Int 2024; 35:1049-1059. [PMID: 38459138 DOI: 10.1007/s00198-024-07047-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 02/27/2024] [Indexed: 03/10/2024]
Abstract
PURPOSE This study aimed to apply a newly developed semi-automatic phantom-less QCT (PL-QCT) to measure proximal humerus trabecular bone density based on chest CT and verify its accuracy and precision. METHODS Subcutaneous fat of the shoulder joint and trapezius muscle were used as calibration references for PL-QCT BMD measurement. A self-developed algorithm based on a convolution map was utilized in PL-QCT for semi-automatic BMD measurements. CT values of ROIs used in PL-QCT measurements were directly used for phantom-based quantitative computed tomography (PB-QCT) BMD assessment. The study included 376 proximal humerus for comparison between PB-QCT and PL-QCT. Two sports medicine doctors measured the proximal humerus with PB-QCT and PL-QCT without knowing each other's results. Among them, 100 proximal humerus were included in the inter-operative and intra-operative BMD measurements for evaluating the repeatability and reproducibility of PL-QCT and PB-QCT. RESULTS A total of 188 patients with 376 shoulders were involved in this study. The consistency analysis indicated that the average bias between proximal humerus BMDs measured by PB-QCT and PL-QCT was 1.0 mg/cc (agreement range - 9.4 to 11.4; P > 0.05, no significant difference). Regression analysis between PB-QCT and PL-QCT indicated a good correlation (R-square is 0.9723). Short-term repeatability and reproducibility of proximal humerus BMDs measured by PB-QCT (CV: 5.10% and 3.41%) were slightly better than those of PL-QCT (CV: 6.17% and 5.64%). CONCLUSIONS We evaluated the bone quality of the proximal humeral using chest CT through the semi-automatic PL-QCT system for the first time. Comparison between it and PB-QCT indicated that it could be a reliable shoulder BMD assessment tool with acceptable accuracy and precision. This study developed and verify a semi-automatic PL-QCT for assessment of proximal humeral bone density based on CT to assist in the assessment of proximal humeral osteoporosis and development of individualized treatment plans for shoulders.

Takeda Y, Fujii K, Suzue N, Kawasaki Y, Sumitomo J, Nishidono K, Fujii Y, Kano M. A modified Patte classification system for rotator cuff tendon retraction to predict reparability and tendon healing in arthroscopic rotator cuff repair. Knee Surg Sports Traumatol Arthrosc 2024; 32:1579-1590. [PMID: 38545631 DOI: 10.1002/ksa.12162] [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: 12/11/2023] [Revised: 03/09/2024] [Accepted: 03/12/2024] [Indexed: 05/31/2024]
Abstract
PURPOSE The purpose of this study was to propose a modified Patte classification system for tendon retraction, including the cut-off points for predicting reparability and rotator cuff healing after arthroscopic rotator cuff repair (ARCR) and assess its prediction accuracy and measurement reliability. METHODS This retrospective study included 463 consecutive patients scheduled to undergo ARCR for full-thickness supraspinatus tears. Receiver operating characteristic (ROC) curve analysis was used to determine the cut-off points for predicting reparability and tendon healing. The modified Patte classification system, in which these cut-off points were combined with the original Patte classification, classified the tendon retraction as stages I-V. The prediction accuracy of reparability and tendon healing was assessed using the area under the curve (AUC). Measurement reliability was determined using Cohen's κ statistics. RESULTS Of the 402 included patients, 32 rotator cuff tears were irreparable and 71 of the remaining 370 were diagnosed with healing failure. ROC analysis determined the cut-off point of reparability at the medial one-fifth and that of tendon healing at the medial one-third of the humeral head. The AUC of the modified Patte classification for predicting reparability and tendon healing was 0.897 (excellent) and 0.768 (acceptable), respectively. Intra-rater reliability was almost perfect (mean κ value: 0.875), and inter-rater reliability was substantial (0.797). CONCLUSION Diagnostic performance of the modified Patte classification system was excellent for reparability and acceptable for rotator cuff healing, with high measurement reliability. The modified Patte classification system can be easily implemented in clinical practice for planning surgical procedures and counselling patients in the day-by-day clinical work.

Biologic Adjuvants to Rotator Cuff Repairs Induce Anti-inflammatory Macrophage 2 Polarization and Reduce Inflammatory Macrophage 1 Polarization In Vitro. Arthroscopy 2024:S0749-8063(24)00337-2. [PMID: 38735413 DOI: 10.1016/j.arthro.2024.04.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/01/2024] [Revised: 04/18/2024] [Accepted: 04/26/2024] [Indexed: 05/14/2024]
Abstract
PURPOSE To examine the effect of various biologic adjuvants on the polarization of macrophages in an in vitro model for rotator cuff tears. METHODS Tissue was harvested from 6 patients undergoing arthroscopic rotator cuff repair. An in vitro model of the supraspinatus and subacromial bursa was created and treated with control, platelet-rich plasma (PRP), autologous activated serum (AAS), or a combination of PRP+AAS. The effect of treatment on macrophage polarization between M1 proinflammatory macrophages or M2 anti-inflammatory macrophages was measured using gene expression, protein expression, flow cytometry, and nitric oxide production. RESULTS Tendon and bursa treated with PRP, AAS, and PRP+AAS significantly decreased the gene expression of M1 markers interleukin (IL)-12 and tumor necrosis factor-alpha while significantly increasing the expression of M2 markers arginase, IL-10, and transforming growth factor-β (P < .05) compared with treatment with control. Enzyme-linked immunosorbent assay analysis of protein production demonstrated that, compared with control, coculture treated with PRP, AAS, and PRP+AAS significantly decreased markers of M1-macrophages (IL-6, IL-12, and tumor necrosis factor-alpha) while significantly increasing the expression of markers of M2-macrophages (arginase, IL-10, and transforming growth factor-beta) (P < .05). Flow cytometry analysis of surface markers demonstrated that compared with control, tendon and bursa treated with PRP, AAS, and PRP+AAS significantly decreased markers of M1-macrophages (CD80, CD86, CD64, CD16) while significantly increasing the expression of markers of M2-macrophages (CD163 and CD206) (P < .05). Treatment of the coculture with PRP, AAS, and PRP+AAS consistently demonstrated a decrease in nitric oxide production (P < .05) compared with control. AAS and PRP+AAS demonstrated an increased macrophage shift to M2 compared with PRP alone, whereas there was not as uniform of a shift when comparing PRP+AAS with AAS alone. CONCLUSIONS In an in vitro model of rotator cuff tears, the treatment of supraspinatus tendon and subacromial bursa with PRP, AAS, and PRP+AAS demonstrated an increase in markers of anti-inflammatory M2-macrophages and a concomitant decrease in markers of proinflammatory M1-macrophages. AAS and PRP+AAS contributed to a large shift to macrophage polarization to the anti-inflammatory M2 compared with PRP. CLINICAL RELEVANCE The mechanism of biologic adjuvant effects on the rotator cuff remains poorly understood. This study suggests that they may contribute to polarization of macrophages for their proinflammatory (M1) state to the anti-inflammatory (M2) state.

Arthroscopic Repair of Retracted Large and Massive Rotator Cuff Tears With and Without Augmentation With a Bio-Inductive Collagen Implant Reveals Substantial and Comparable Clinical Improvement. Arthroscopy 2024; 40:1434-1442. [PMID: 37931669 DOI: 10.1016/j.arthro.2023.10.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2023] [Revised: 10/11/2023] [Accepted: 10/20/2023] [Indexed: 11/08/2023]
Abstract
PURPOSE To compare clinical and imaging results after repair of retracted large and massive full-thickness rotator cuff tears, including revision repairs, with and without augmentation with a bio-inductive collagen implant. METHODS The study group comprised 24 patients (17 male subjects) with retracted 2 or 3 tendon rotator cuff tears undergoing arthroscopic repair followed by onlay augmentation with a bio-inductive collagen implant. The control group comprised 24 patients (19 male subjects) matched by tear size undergoing repair without augmentation. Mean patient age at repair in both groups was 61 years. Active range of motion and patient-reported outcomes were recorded before and after surgery. Noncontrast high-field magnetic resonance imaging was obtained in 20 of 24 collagen implant patients and 17 of 24 control patients at minimum 6 months' follow-up to assess tendon healing. RESULTS American Shoulder and Elbow Surgeons and Simple Shoulder Test scores improved from 35 to 86 and 3.6 to 9.3, respectively, in the collagen implant group and from 39 to 87 and 3.9 to 9.7 in the control group. The visual analog score-pain improved from 6.0 to 0.9 and from 5.9 to 0.9 in the collagen implant and control groups, respectively (P < .001 for all). Overall improvements in range of motion and patient-reported outcomes were similar in both groups. Magnetic resonance imaging revealed intact repairs in 11 of 20 (55%) patients in the patch group and 9 of 17 (53%) in the control group. Two patients in each group were revised to reverse shoulder arthroplasty. CONCLUSIONS Arthroscopic repair of retracted large and massive rotator cuff tears, including revision repairs, with and without augmentation using a bio-inductive collagen implant results in substantial and comparable early clinical improvement, although predictable healing remains elusive. Further work is needed to optimize patient selection for massive rotator cuff repair and define more precisely the indications for augmentation of these repairs using the collagen implant.

Abstract
Introduction Arthroscopic advancements have notably improved rotator cuff repair, yet the healing of tendons and retear risks still pose significant challenges, especially with massive and large tears. These larger tears have shown a quadruple increase in retear rate when the tear size grows from 1-3 cm. The prevalent cause of failure, particularly in tears with fatty degeneration, is suture tearing. As such, techniques that enhance tendon healing are pivotal due to their correlation with improved functional outcomes. Dermal allograft augmentation (DAA) is one method that has demonstrated improvements in rotator cuff repair biomechanics, as well as the promotion of vascularization and neotendon formation. This study evaluates the efficacy of DAA in the postoperative healing of large and massive rotator cuff tears, assessed through patient-reported outcomes and functional range of motion. Methods This retrospective study reviewed a single surgeon's database, selecting patients who underwent arthroscopic surgery for full-thickness rotator cuff tears measuring at least 3 cm, or those with maximum stage II fatty infiltration of the supraspinatus or infraspinatus muscle on MRI. We used three validated patient-reported outcome (PRO) measures, American Shoulder and Elbow Surgeon Score (ASES), Single Assessment Numeric Evaluation (SANE), and Simple Shoulder Test (SST), alongside a range of motion metrics, external rotation (ER), and forward flexion (FF). These were recorded pre-operatively and, at minimum, one year post-operatively, with a standard student t-test employed for comparative analysis. Results Out of 18 total patients, the average age was 61 years, and 83% were male. The cause of injury was mostly traumatic in nature (n=11), with the remainder being chronic (n=7). All three PROs (n=11) demonstrated a statistically significant increase in score including ASES (p=0.003), SANE (p=0.004), and SST (p=0.039). External rotation also significantly improved pre- to post-operative function (46 vs 58, p=0.049). Three patients (17%) suffered from a retear within three months of their rotator cuff repair. Two patients (11%) required a reverse shoulder arthroplasty within a year. Conclusion Our study demonstrated that DAA in rotator cuff repair yielded notable functional and clinical advancements, with a moderately low retear rate as confirmed by ultrasound. These outcomes suggest that DAA is a promising intervention for large and historically difficult rotator cuff tears, offering significant implications for future treatment protocols.

Abstract
PURPOSE To perform a meta-analysis of randomized controlled trials (RCTs) to compare the outcomes of arthroscopic rotator cuff repair (ARCR) with and without acellular collagen matrix patch (ACMP) augmentation. METHODS A literature search of 3 databases was performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. RCTs comparing ACMP augmentation and a control for ARCR were included. Clinical outcomes were compared using Revman, and a P value < .05 was considered to be statistically significant. RESULTS Five RCTs with 307 patients were included. Overall, 11% of patients treated with ACMP augmentation and 34% of patients in the control group had a re-tear (P = .0006). The mean Constant score was 90.1 with ACMP augmentation, and 87.3 in controls (P = .02). Additionally, there was a significant higher American Shoulder and Elbow Surgeons score with ACMP augmentation (87.7 vs 82.1, P = .01). CONCLUSIONS The RCTs in the literature support the use of ACMP augment as a modality to reduce re-tear rates and improve outcomes after ARCR.

Abstract
Understanding the preoperative risk factors for successful rotator cuff repair (RCR) and ways to optimize these factors is an evolving area of study. The Rotator Cuff Healing Index and other proxy risk factors for failed rotator cuff healing have implicated significant fatty infiltration, muscular atrophy, advanced chronological age, tear size and retraction, and ultimately, osteoporosis. Although structural (or biological) augmentation and tendon transfer have been proposed as solutions for the alarmingly high rate of failure after primary RCR, other options may preferentially focus on the enthesis and underlying osseous footprint. Currently, bisphosphonates are frequently used in the treatment of osteoporosis and prevention of fragility fractures. However, burgeoning evidence suggests that postoperative zoledronic acid may have clinical utility after rotator cuff and other tendon repairs. In the cost-conscious world of evidence-based medicine, the added economic burden of additional medications and office visits may or may not improve patient outcomes-much less confer added value. Our advice to fellow shoulder surgeons: Wait for further information, but continue to holistically consider and optimize risk factors for poor soft-tissue healing. Although the addition of postoperative bisphosphonates may improve suture anchor fixation and promote a better foundation for healing, it will not immediately transform your RCR success rates.

Abstract
The study aimed to describe the changes in biomechanical properties of the supraspinatus tendon, deltoid muscle, and humeral head post arthroscopic rotator cuff repair using shear wave elastography. Shear wave velocity of the tendon, deltoid, and humeral head of 48 patients was measured at predetermined sites at 1 week, 6 weeks, 12 weeks, 6 months, and 12 months post repair. One-way ANOVA with Tukey's correction and Spearman's correlation were performed. Mean±SEM healing tendon stiffness, adjacent to tendon footprint, increased from 1 week (6.2±0.2 m/s) to 6 months (7.5±0.3 m/s) and 12 months (7.8±0.3 m/s) (P<0.001). Mean±SEM deltoid muscle stiffness was higher at 12 months (4.1±0.2 m/s) compared to 1 week (3.4±0.1 m/s) and 12 weeks (3.5±0.1 m/s) (P<0.05). Humeral head stiffness did not change. Following arthroscopic rotator cuff repair, supraspinatus tendon stiffness increased in a curvilinear fashion over 6 months. From 6 months, deltoid muscle stiffness increased, corresponding to when patients were instructed to return to normal activities.

Abstract
BACKGROUND Magnetic resonance (MR) imaging is the most common modality for assessment of the rotator cuff before and after surgery. Several classifications have been described aiming to define main tear characteristics. However, there is still confusion when it comes to the reliability of those classifications. PURPOSE (1) To identify all MR classifications available in the literature for preoperative assessment of rotator cuff tears, (2) to summarize available data on the reliability of identified classifications, and (3) to assess the methodological quality of reliability studies. STUDY DESIGN Systematic review; Level of evidence, 4. METHODS This systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. All studies reporting MR assessment in patients with a superior or posterosuperior rotator cuff tear were included. After identification of the available MR criteria, reliability studies were analyzed. Descriptive statistics were used to summarize findings. Methodological quality was assessed using the Quality Appraisal of Reliability Studies checklist. RESULTS A total of 75 studies were included in this review. Eight categories of outcomes could be identified. Of the total, 62 studies reported interobserver reliability whereas 32 reported intraobserver reliability of some of the identified criteria. Each category reflected a variety of reliability, ranging from poor to excellent agreement. MR proved to be a reliable imaging modality to detect the structural integrity of the posterosuperior cuff, especially in cases of full-thickness tear; it was also reliable in terms of tear width and length and muscle atrophy based on a tangent sign or Thomazeau classification. All other classifications did not prove acceptable reliability. Methodological quality was high for 23 articles and moderate for 14. CONCLUSION Preoperative MR is a reliable imaging modality to identify full-thickness tears, measure tear size and morphology, and identify muscle atrophy with tangent sign or Thomazeau classification. All other outcomes and classifications did not show acceptable reliability; therefore, caution is needed when using them for preoperative evaluation of a rotator cuff tear.

Abstract
Rotator cuff tears are the most frequent shoulder injury in patients over 50 years old. Treatment of rotator cuff tears is individualized based on the age, demands, and symptoms of the patient. Nonoperative treatment may often be effective, especially in lower-demand or elderly patients. Surgical repair is indicated after failure of nonoperative treatment or in patients whose high-demand lifestyle requires full strength and function of the shoulder. In older patients, larger tears are less likely to heal and rotator cuff repair may not reliable. In cases of failed previous rotator cuff repair, there may not be enough viable tissue for complete repair. If there is underlying arthritis, a rotator cuff repair is unlikely to resolve all symptoms, and treatment to care for the arthritis and rotator cuff tear is indicated. Reverse shoulder arthroplasty provides the surgical answer for these scenarios and is now being used for numerous indications of shoulder pathology.

Abstract
Rotator cuff tears are the most common upper extremity condition seen by primary care and orthopaedic surgeons, with a spectrum ranging from tendinopathy to full-thickness tears with arthritic change. Some tears are traumatic, but most rotator cuff problems are degenerative. Not all tears are symptomatic and not all progress, and many patients in whom tears become more extensive do not experience symptom worsening. Hence, a standard algorithm for managing patients is challenging. The pathophysiology of rotator cuff tears is complex and encompasses an interplay between the tendon, bone and muscle. Rotator cuff tears begin as degenerative changes within the tendon, with matrix disorganization and inflammatory changes. Subsequently, tears progress to partial-thickness and then full-thickness tears. Muscle quality, as evidenced by the overall size of the muscle and intramuscular fatty infiltration, also influences symptoms, tear progression and the outcomes of surgery. Treatment depends primarily on symptoms, with non-operative management sufficient for most patients with rotator cuff problems. Modern arthroscopic repair techniques have improved recovery, but outcomes are still limited by a lack of understanding of how to improve tendon to bone healing in many patients.

Abstract
PURPOSE To identify patient preoperative history, examination, and imaging characteristics that increase the risk of postoperative failure of gluteus medius/minimus repair, and to develop a decision-making aid predictive of clinical outcomes for patients undergoing gluteus medius/minimus repair. METHODS Patients from 2012 to 2020 at a single institution undergoing gluteus medius/minimus repair with minimum 2-year follow-up were identified. MRIs were graded according to the "three-grade" classification system: grade 1: partial-thickness tear, grade 2: full-thickness tears with <2 cm of retraction, grade 3: full-thickness tears with ≥2 cm retraction. Failure was defined as undergoing revision within 2 years postoperatively or not achieving both a cohort-calculated minimal clinically important difference (MCID) and responding "no" to patient acceptable symptom state (PASS). Inversely, success was defined as reaching both an MCID and responding "yes" to PASS. Predictors of failure were verified on logistic regression and a predictive scoring model, the Gluteus-Score-7, was generated to guide treatment-decision making. RESULTS In total, 30 of 142 patients (21.1%) were clinical failures at mean ± SD follow-up of 27.0 ± 5.2 months. Preoperative smoking (odds ratio [OR], 3.0; 95% confidence interval [CI], 1.0-8.4; P = .041), lower back pain (OR, 2.8; 95% CI, 1.1-7.3; P = .038), presence of a limp or Trendelenburg gait (OR, 3.8; 95% CI, 1.5-10.2; P = .006), history of psychiatric diagnosis (OR, 3.7; 95% CI, 1.3-10.8; P = .014), and increased MRI classification grades (P ≤ .042) were independent predictors of failure. The Gluteus-Score-7 was generated with each history/examination predictor assigned 1 point and MRI classes assigned corresponding 1-3 points (min 1, max 7 score). A score of ≥4/7 points was associated with risk of failure and a score ≤2/7 points was associated with clinical success. CONCLUSIONS Independent risk factors for revision or not achieving either MCID or PASS after gluteus medius and/or minimus tendon repair include smoking, preoperative lower back pain, psychiatric history, Trendelenburg gait, and full-thickness tears, especially tears with ≥2 cm retraction. The Gluteus-Score-7 tool incorporating these factors can identify patients at risk of both surgical treatment failure and success, which may be useful for clinical decision-making.

Abstract
Massive rotator cuff tears are one the most challenging conditions to treat in the shoulder. A variety of surgical approaches have been used to manage massive rotator cuff tears, such as repair with or without augmentation, superior capsule reconstruction, tendon transfer, and reverse shoulder arthroplasty. The choice between joint preservation or reverse shoulder arthroplasty is first considered based on preoperative imaging and functional status, as well as patient factors. When joint preservation is the goal of treatment, a combination of repairability, patient function, and age can be used to provide an algorithmic approach to treatment. LEVEL OF EVIDENCE: Level V, expert opinion.

Abstract
BACKGROUND Healing failure after rotator cuff repair is a challenging problem. Acute, trauma-related tears are considered a separate entity and are often treated surgically. The aim of this study was to identify factors associated with healing failure in previously asymptomatic patients with trauma-related rotator cuff tears treated with early arthroscopic repair. METHODS This study included 62 consecutively recruited patients (23% women; median age, 61 years; age range, 42-75 years) with acute symptoms in a previously asymptomatic shoulder and a magnetic resonance imaging-verified full-thickness rotator cuff tear after shoulder trauma. All patients were offered, and underwent, early arthroscopic repair, during which a biopsy specimen was harvested from the supraspinatus tendon and analyzed for signs of degeneration. Of the patients, 57 (92%) completed 1-year follow-up and underwent assessment of repair integrity on magnetic resonance images according to the Sugaya classification. Risk factors for healing failure were investigated using a causal-relation diagram where age, body mass index, tendon degeneration (Bonar score), diabetes mellitus, fatty infiltration (FI), sex, smoking, tear location regarding integrity of the rotator cable, and tear size (number of ruptured tendons and tendon retraction) were included and analyzed. RESULTS Healing failure at 1 year was identified in 37% of patients (n = 21). A high degree of FI of the supraspinatus muscle (P = .01), a tear location including disruption of rotator cable integrity (P = .01), and old age (P = .03) were associated with healing failure. Tendon degeneration as determined by histopathology was not associated with healing failure at 1-year follow-up (P = .63). CONCLUSION Older age, increased FI of the supraspinatus muscle, and a tear including disruption of the rotator cable increased the risk of healing failure after early arthroscopic repair in patients with trauma-related full-thickness rotator cuff tears.

Abstract
Background Although some evidence suggests that machine learning algorithms may outperform classical statistical methods in prognosis prediction for several orthopaedic surgeries, to our knowledge, no study has yet used machine learning to predict patient-reported outcome measures after rotator cuff repair. Purpose To determine whether machine learning algorithms using preoperative data can predict the nonachievement of the minimal clinically important difference (MCID) of disability at 2 years after rotator cuff surgical repair with a similar performance to that of other machine learning studies in the orthopaedic surgery literature. Study Design Case-control study; Level of evidence, 3. Methods We evaluated 474 patients (n = 500 shoulders) with rotator cuff tears who underwent arthroscopic rotator cuff repair between January 2013 and April 2019. The study outcome was the difference between the preoperative and 24-month postoperative American Shoulder and Elbow Surgeons (ASES) score. A cutoff score was calculated based on the established MCID of 15.2 points to separate success (higher than the cutoff) from failure (lower than the cutoff). Routinely collected imaging, clinical, and demographic data were used to train 8 machine learning algorithms (random forest classifier; light gradient boosting machine [LightGBM]; decision tree classifier; extra trees classifier; logistic regression; extreme gradient boosting [XGBoost]; k-nearest neighbors [KNN] classifier; and CatBoost classifier). We used a random sample of 70% of patients to train the algorithms, and 30% were left for performance assessment, simulating new data. The performance of the models was evaluated with the area under the receiver operating characteristic curve (AUC). Results The AUCs for all algorithms ranged from 0.58 to 0.68. The random forest classifier and LightGBM presented the highest AUC values (0.68 [95% CI, 0.48-0.79] and 0.67 [95% CI, 0.43-0.75], respectively) of the 8 machine learning algorithms. Most of the machine learning algorithms outperformed logistic regression (AUC, 0.59 [95% CI, 0.48-0.81]); nonetheless, their performance was lower than that of other machine learning studies in the orthopaedic surgery literature. Conclusion Machine learning algorithms demonstrated some ability to predict the nonachievement of the MCID on the ASES 2 years after rotator cuff repair surgery.

Abstract
BACKGROUND It is challenging to predict retear after arthroscopic rotator cuff repair (ARCR). The usefulness of arthroscopic intraoperative images as predictors of the ARCR prognosis has not been analyzed. PURPOSE To evaluate the usefulness of arthroscopic images for the prediction of retear after ARCR using deep learning (DL) algorithms. STUDY DESIGN Cohort study (Diagnosis); Level of evidence, 2. METHODS In total, 1394 arthroscopic intraoperative images were retrospectively obtained from 580 patients. Repaired tendon integrity was evaluated using magnetic resonance imaging performed within 2 years after surgery. Images obtained immediately after ARCR were included. We used 3 DL architectures to predict retear based on arthroscopic images. Three pretrained DL algorithms (VGG16, DenseNet, and Xception) were used for transfer learning. Training and test sets were split into 8:2. Threefold stratified validation was used to fine-tune the hyperparameters using the training data set. The validation results of each fold were evaluated. The performance of each model in the test set was evaluated in terms of accuracy, area under the receiver operating characteristic curve (AUC), F1-score, sensitivity, and specificity. RESULTS In total, 1138 and 256 arthroscopic images were obtained from 514 patients and 66 patients in the nonretear and retear groups, respectively. The mean validation accuracy of each model was 83% for VGG16, 89% for Xception, and 91% for DenseNet. The accuracy for the test set was 76% for VGG16, 87% for Xception, and 91% for DenseNet. The AUC was highest for DenseNet (0.92); it was 0.83 for VGG16 and 0.91 for Xception. For the test set, the specificity and sensitivity were 0.93 and 0.84 for DenseNet, 0.89 and 0.84 for Xception, and 0.70 and 0.80 for VGG16, respectively. CONCLUSION The application of DL algorithms to intraoperative arthroscopic images has demonstrated a high level of accuracy in predicting retear occurrences.

Abstract
BACKGROUND Arthroscopic rotator cuff repairs (RCRs) are known to be associated with substantial pain and post-operative pain management is critical in overall patients' outcomes. Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used oral medications and can reduce opioid usage. However, controversies arise due to its postulated effect on postoperative tendon healing. As the evidence of safety and efficacy of NSAIDs remains unclear, this study aims to investigate the effect of NSAIDs on retear rates and clinical outcomes. METHODS A systematic search of four databases (PubMed, EMBASE, Scopus, and Cochrane Library) was conducted, identifying studies that compared cohorts with post-RCR NSAIDs use versus control groups without NSAID use. Meta-analysis was conducted for retear rate as well as pain and functional outcomes (Visual Analogue Scale and American Shoulder and Elbow Surgeons Shoulder score). Subgroup analysis was conducted for retear rates to determine the overall treatment effect of including selective COX-2 inhibitors. RESULTS Six studies were included in the meta-analysis. The total baseline cohort size was 916, with 443 (48.3%) patients in the NSAID group and 473 (51.6%) patients in the control group. There were no statistically significant differences in the baseline characteristics between the two groups. Meta-analysis between the two groups showed that there were no statistically significant differences in retear rates (p = 0.70), early and late post-operative Visual Analogue Scale score (p = 0.10 and p = 0.10, respectively) and latest American Shoulder and Elbow Surgeons Shoulder score (p = 0.31). However, subgroup analysis of retear rates revealed a statistically significant difference between the subgroup including COX-2 selective inhibitor versus non-selective COX inhibitor (p < 0.01). CONCLUSION NSAID use in post-arthroscopic RCR pain relief does not increase retear rates and can provide similar clinical outcomes compared to a non-NSAID regimen. LEVEL OF EVIDENCE Meta-analysis, level of evidence, 4.

Abstract
Nonoperative and operative strategies exist to manage rotator cuff pathology. Although surgical repair is successful for most patients, others may experience retear or nonhealing of the rotator cuff. Several modifiable and nonmodifiable risk factors are associated with an increased retear rate. The literature shows consistency and agreement regarding many of these risk factors, most notably, patient age, tear size, and rotator cuff muscular atrophy, whereas others remain controversial. It is important that shoulder surgeons are familiar with modifiable and nonmodifiable risk factors associated with retear, to better advise patients and optimize their chances of success following rotator cuff repair surgery.

Abstract
Background The aim of this study was to compare the clinical outcomes and retear rate of arthroscopic superior capsular reconstruction (SCR) with dermal allograft following structural failure of a previous rotator cuff repair, with a cohort of primary SCRs. Methods This was a retrospective comparative study with a study group comprising 22 patients who were followed up at a minimum of 24 (mean, 41; range, 27-65) months after SCR with dermal allograft performed for structural failure of a previous rotator cuff repair. The control group included 13 patients who previously underwent a primary SCR using dermal allograft and were followed up for 24 months. Clinical outcome measures comprised range of motion, the American Shoulder and Elbow Surgeons score, and the Western Ontario Rotator Cuff (WORC) Index. Radiological outcomes included the acromiohumeral interval and graft integrity on magnetic resonance imaging at one year. Logistic regression was used to determine whether SCR being undertaken as either a primary or revision procedure influenced functional outcomes or retear rate. Results The mean age at the time of surgery was 58 (range, 39-74) years for the study group and 60 (range, 48-70) years for the control group. Forward flexion improved from a mean of 117° (range, 7°-180°) preoperatively to 140° (range, 45°-170°) postoperatively (P = .11), and external rotation increased from a mean of 31° (range, 0°-70°) preoperatively to 36° (range, 0°-60°) postoperatively (P = .23). The American Shoulder and Elbow Surgeons score improved (P = 0) from a mean of 38 (range, 12-68) to 73 (range, 17-95), and the WORC Index improved (P = 0) from a mean of 29 (range, 7-58) to 59 (range, 30-97). Following SCR, there was no significant change in the acromiohumeral interval. The graft was intact in 42% of cases on magnetic resonance imaging and none of the retears underwent further surgery. Compared to revision SCR, primary SCR resulted in a significant improvement in forward flexion (P = .001), external rotation (P = 0), and WORC Index (P = .019). Logistic regression demonstrated that SCR performed as a revision procedure was associated with a higher retear rate (P = .006) and worse forward flexion (P = .009) and external rotation (P = .008). Conclusion SCR using human dermal allograft following structural failure of a previous rotator cuff repair can lead to an improvement in clinical outcomes but the results are inferior to primary procedures.

Abstract
BACKGROUND There is no practical consensus on managing cholesterol in patients with rotator cuff repair despite hyperlipidemia and statin therapy being well-known factors in rotator cuff healing. The 10-year atherosclerotic cardiovascular disease (ASCVD) risk score is a commonly used guideline to determine statin administration for hyperlipidemia. PURPOSE To identify the relationship between retear and preoperative factors, including 10-year ASCVD risk score and statin administration status, and to compare clinical outcomes and retear rates between patients who are taking and not taking statins. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This study enrolled 182 patients with a symptomatic full-thickness rotator cuff tear who underwent arthroscopic repair. Serum lipid profile, 10-year ASCVD risk score, statin eligibility, and statin administration status were assessed. Patients were categorized into 2 groups based on magnetic resonance imaging to evaluate cuff integrity at postoperative 6 months: a healed group and a retear group. Radiographic and intraoperative factors related to retear were analyzed. Multiple regression analysis was performed to evaluate factors related to rotator cuff retear. For the subgroup analysis, patients eligible for statin therapy were divided into 2 subgroups according to administration status. RESULTS There were 149 (81.9%) patients in the healed group and 33 (18.1%) in the retear group. In the multiple regression analysis, missed statin therapy, 10-year ASCVD risk score, and fatty infiltration of the infraspinatus muscle were the independent factors related to retear. The cutoff value for 10-year ASCVD risk score was 11.85%, with a sensitivity of 0.75 and a specificity of 0.62. In the subgroup analysis of 104 patients eligible for statin therapy, 66 (63.5%; group 1) received statin therapy and 38 (36.5%; group 2) missed it. Group 2 showed a significantly higher retear rate than group 1 (36.8% vs 13.6%; P = .006). CONCLUSION Missed statin therapy, 10-year ASCVD risk score, and fatty infiltration of the infraspinatus were the independent factors associated with rotator cuff retear. Patients who missed statin therapy showed a higher retear rate than patients receiving statin therapy. Optimal statin therapy for patients who undergo arthroscopic rotator cuff repair might improve repair integrity.

Abstract
Background The success rate of surgical treatment for rotator cuff (RC) tear ranges from 16% to 94%. The Rotator Cuff Healing Index (RoHI) is a system for predicting failure after RC repair and is based on a combined score of factors, including age, anteroposterior (AP) tear size, tendon retraction, fatty infiltration of the infraspinatus muscle, bone mineral density (BMD), and level of work activity. Purpose To determine the factors leading to RC repair failure in a Thai population, to test the reliability of the RoHI in this population, and to compare the RoHI with a modified RoHI (m-RoHI) based on the factors for repair failure as determined. Study Design Case-control study; Level of evidence, 3. Methods This study included 133 Thai patients who underwent arthroscopic RC repair between February 2012 and February 2021. Postoperative magnetic resonance imaging was performed at 6 to 24 months to evaluate RC healing. Variables that might affect failure rates were evaluated, including demographic characteristics, AP tear size and retraction, radiographic measurements, and magnetic resonance imaging findings. The m-RoHI was created using factors that significantly predicted repair failure on multivariate analysis. The area under the receiver operating characteristic curve was calculated to determine the reliability of the RoHI and to compare the reliability of the RoHI and m-RoHI to predict failure rates. Results Multivariate logistic regression analysis revealed that body mass index ≥23 (adjusted odds ratio [OR], 9.02; P = .034), high work activity (adjusted OR, 19.53; P = .008), AP tear size ≥2.5 cm (adjusted OR, 19.04; P = .001), and a retraction size of 2 to <3 cm (adjusted OR, 20.36; P = .013) were the independent factors that predicted repair failure in our population. BMD was not independently predictive of repair failure. We used these 4 significant independent factors to generate the m-RoHI. The area under the curve of the final adjusted m-RoHI was slightly improved as compared with the original RoHI, but this difference was not significant (0.827 [95% CI, 0.741-0.913] vs 0.780 [95% CI, 0.686-0.875], respectively; P = .447). Conclusion The m-RoHI had a similar predictive value for repair failure to the original RoHI in our study population, but it did not require obtaining BMD. The m-RoHI may be useful in populations where BMD is not routinely obtained.

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.

Abstract
INTRODUCTION To highlight the preoperative risk factors that influence postoperative patient satisfaction following Rotator Cuff Repair (RCR) and to determine whether this satisfaction was correlated with tendon healing. HYPOTHESIS Preoperative factors influence patient satisfaction, assessed by SSV (Subjective Shoulder Value) postoperatively, with a correlation with tendon healing. METHODS With a mean age of 60.6 years (40-72), 102 patients with arthroscopic RCR were included retrospectively. The preoperative SSV score was less than or equal to 50%. There was clinical and radiological follow-up with an ultrasound evaluation of tendon healing 6 months postoperatively. We divided the patients into 2 groups using a postoperative SSV of 85% as the cut-off; 55 patients in the first group (SSV>85%); and 47 patients in the second group (SSV<85%). RESULTS In multivariate analysis, Preoperative risk factors for poor postoperative SSV after RCR were: tobacco use [-8.41 (-13.64; -3.17) p=0.002], fatty infiltration [-3.65 (-6.24 -1.06) p=0.006] and workers compensation [-19.15 (-24.04; -14.27) p<0.001]. When patients were not in workers compensation, the lower their SSV score before surgery, the higher their postoperative SSV score. For patients in workers compensation, the higher the SSV preoperatively, the less elevated was SSV postoperatively. The Sugaya ultrasound classification did not influence the SSV score (p=0.15) CONCLUSIONS: Smoking, fatty infiltration and patients in workers compensation are factors of poorer subjective results evaluated by the SSV score. Tendon healing did not influence the SSV score and patient satisfaction. LEVEL OF EVIDENCE IV, cohort study.

Abstract
BACKGROUND The high incidence of incomplete or failed healing after rotator cuff repair (RCR) has led to an increased focus on the biologic factors that affect tendon-to-bone healing. Inflammation plays a critical role in the initial tendon-healing response. C-C chemokine receptor type 2 (CCR2) is a chemokine receptor linked to the recruitment of monocytes in early inflammatory stages and is associated with an increase in pro-inflammatory macrophages. The purpose of this study was to evaluate the role of CCR2 in tendon healing following RCR in C57BL/6J wildtype (WT) and CCR2-/- knockout (CCR2KO) mice in a delayed RCR model. METHODS Fifty-two 12-week-old, male mice were allocated to 2 groups (WT and CCR2KO). All mice underwent unilateral supraspinatus tendon (SST) detachment at the initial surgical procedure, followed by a delayed repair 2 weeks later. The primary outcome measure was biomechanical testing. Secondary measures included histology, gene expression analysis, flow cytometry, and gait analysis. RESULTS The mean load-to-failure was 1.64 ± 0.41 N in the WT group and 2.50 ± 0.42 N in the CCR2KO group (p = 0.030). The mean stiffness was 1.43 ± 0.66 N/mm in the WT group and 3.00 ± 0.95 N/mm in the CCR2KO group (p = 0.008). Transcriptional profiling demonstrated 7 differentially expressed genes (DEGs) when comparing the CCR2KO and WT groups (p < 0.05) and significant differences in Type-I and Type-II interferon pathway scores (p < 0.01). Flow cytometry demonstrated significant differences between groups for the percentage of macrophages present (8.1% for the WT group compared with 5.8% for the CCR2KO group; p = 0.035). Gait analysis demonstrated no significant differences between groups. CONCLUSIONS CCR2KO may potentially improve tendon biomechanical properties by decreasing macrophage infiltration and/or by suppressing inflammatory mediator pathways in the setting of delayed RCR. CLINICAL RELEVANCE CCR2 may be a promising target for novel therapeutics that aim to decrease failure rates following RCR.

Abstract
PURPOSE Many previous research efforts have been made to identify prognostic factors for rotator cuff healing. However, majority of these studies were conducted with heterogeneous cohorts consisted of different tear characteristics. Healing properties of a rotator cuff tear may differ depending on tear characteristics such as tear size or fatty infiltration. Therefore, studies with subgroups confined by these variables may reflect more accurate results. This study aims to investigate predictive factors for rotator cuff healing in a subgroup with small- to medium-sized tears without significant fatty infiltration. METHODS This retrospective case-control study was conducted with 94 patients with small- to medium-sized rotator cuff tears. Mean age of patients was 56.0 ± 9.0 years and mean follow-up duration was 38.3 ± 8.1 months. Post-operative magnetic resonance imaging assessment showed that there were 75 (79.8%) successfully healed repairs and 19 (20.2%) healing failures. Age, gender, hand dominancy, body mass index (BMI), smoking habit, diabetes, corticosteroid injection, baseline clinical status, duration of surgery and biceps procedure were variables evaluated as predictive factors. RESULTS Both study groups showed significant improvement from baseline regarding clinical outcome measures (p < 0.05). However, successfully healed patients had significantly higher post-operative functional scores and lower pain scores (p < 0.05). The univariate analysis revealed that healing was significantly affected by age (p = 0.004), BMI (p = 0.01) and diabetes (p = 0.03). In the multivariate analysis, age (p = 0.02) and BMI (p = 0.02) were found to be significant independent factors for healing. Cutoff values for oldest age and highest BMI were 63 years and 28.1 kg/m2, respectively, for a successful healing according to receiver-operating characteristic curve analysis. CONCLUSION Healing failure after rotator cuff repair in small- to medium-sized tears is associated with poorer outcomes. Age and BMI are independent predictive factors for healing. A successful repair is more likely in patients younger than 63 years and with BMI less than 28.1 kg/m2. Surgeons should consider this information during risk assessment, decision making and patient counselling. LEVEL OF EVIDENCE Level III.

Abstract
BACKGROUND High rates of structural failure are reported after rotator cuff repairs due to inability to recreate the native enthesis during healing. The development of biological augmentation methods that mitigate scar formation and regenerate the enthesis is still an unmet need. Since neonatal enthesis is capable of regeneration after injury, this study tested whether delivery of neonatal tendon progenitor cells (TPCs) into the adult injured environment can enhance functional and structural supraspinatus enthesis and tendon healing. METHODS TPCs were isolated from Ai14 Rosa26-TdTomato mouse Achilles tendons and labeled using adenovirus-Cre. Fifty-two CB57BL/6J mice underwent detachment and acute repair of the supraspinatus tendon and received either a fibrin-only or TPC-fibrin gel. Immunofluorescence analysis was carried out to determine cellularity (DAPI), fibrocartilage (SOX9), macrophages (F4/80), myofibroblasts (α-smooth muscle actin), and scar (laminin). Assays for function (gait and biomechanical testing) and structure (micro-computed tomography imaging, picrosirius red/Alcian Blue staining, type I and III collagen staining) were carried out. RESULTS Analysis of TdTomato cells after injury showed minimal retention of TPCs by day 7 and day 14, with detected cells localized near the bursa and deltoid rather than the enthesis/tendon. However, TPC delivery led to significantly increased %Sox9+ cells in the enthesis at day 7 after injury and decreased laminin intensity across almost all time points compared to fibrin-only treatment. Similarly, TPC-treated mice showed gait recovery by day 14 (paw area and stride length) and day 28 (stance time), while fibrin-treated mice failed to recover gait parameters. Despite improved gait, biomechanical testing showed no differences between groups. Structural analysis by micro-computed tomography suggests that TPC application improves cortical thickness after surgery compared to fibrin. Superior collagen alignment at the neo-enthesis was also observed in the TPC-augmented group at day 28, but no difference was detected in type I and III collagen intensity. CONCLUSION We found that neonatal TPCs improved and restored functional gait by reducing overall scar formation, improving enthesis collagen alignment, and altering bony composition response after supraspinatus tendon repair. TPCs did not appear to integrate into the healing tissue, suggesting improved healing may be due to paracrine effects at early stages. Future work will determine the factors secreted by TPCs to develop translational targets.

Abstract
Posterosuperior rotator cuff tear (PSRCT) is one of the most common shoulder disorders in elderly people’s daily life; however, the biomechanical relationship between PSRCT and shoulder abduction function is still controversial. In this study, a total of twelve freshly frozen cadaveric shoulders were included and tested in five conditions: intact rotator cuff, 1/3 PSRCT, 2/3 PSRCT, entire PSRCT, and global RCT. In each condition, extra load (0%, 45%, and 90% failure load) was sequentially added to the distal humerus, and the function of the remaining rotator cuff was mainly evaluated via the middle deltoid force (MDF) required for abduction. It is found that the peak MDF is required for abduction did not differ among the three PSRCT conditions (1/3 PSRCT: 29.30 ± 5.03 N, p = 0.96; 2/3 PSRCT: 29.13 ± 9.09 N, p = 0.98; entire PSRCT: 28.85 ± 7.12 N, p = 0.90) and the intact condition (29.18 ± 4.99 N). However, the peak MDF significantly differed between the global RCT (76.27 ± 4.94 N, p < 0.01) and all PSRCT and intact conditions. Under 45% failure load, the MDF of the entire PSRCT and global tear conditions were significantly increased compared with another status. With the 90% failure load, only the 1/3 PSRCT condition maintained the same shoulder function as the intact rotator cuff. These biomechanical testing jointly suggested that the weight-bearing ability of the shoulder significantly decreased as PSRCT progressed.

Abstract
PURPOSE This study aimed to evaluate the effect of retear on long-term functional outcomes and glenohumeral joint osteoarthritis (OA) progression after arthroscopic rotator cuff repair (ASRCR). METHODS We retrospectively reviewed 201 patients who underwent ASRCR and were followed up for at least 5 years. Rotator cuff tendon structural integrity was evaluated using magnetic resonance imaging and/or ultrasonography. Pain, active range of motion, and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) were evaluated for functional outcomes. To evaluate deterioration over time, the minimal clinically important difference value of pain and ASES were used. RESULTS The mean follow-up period was 8.6 ± 2.2 years and overall retear rate was 21.4%. OA progression was strongly associated with retear (odds ratio 5.1, P < .001). Functional outcomes at the 2-year postoperative follow-up significantly improved compared to the preoperative status (all P < .017), regardless of retear. However, the retear group presented worse functional outcomes at the final follow-up (pain: 3.1 ± 2.6; ASES: 72.0 ± 17.4) than at the 2-year postoperative follow-up (pain: 1.2 ± 2.3, P = .014; ASES: 91.1 ± 9.9, P= .015) than the healed tendon group at final follow-up (pain: .6 ± 1.7; P < .001; ASES 95.5 ± 11.8; P < .001). The time for deterioration of pain (healed group vs. retear group: 5.5 ± 0.5 vs. 10.6 ± 0.4 years; P < .001) and ASES (healed group vs. retear group: 7.5 ± 0.5 vs. 12.8 ± 0.2 years; P < .001) decreased in the retear group. CONCLUSIONS The functional status improved after ASRCR in short- and long-term follow-up, regardless of retear. However, retear was strongly associated with OA progression, and long-term functional outcomes deteriorated over time in retear cases, which was not observed during short-term follow-up.

Abstract
Background Lipid deposition secondary to dyslipidemia (DLD) is shown to have a significant impact on tendon pathology, including tendon elasticity, fatty infiltration, and healing properties. Rotator cuff repair is a common procedure, susceptible to influence from many tear-related and patient-related characteristics. The purpose of this study was to determine the relationship between DLD and rotator cuff repair outcomes with analysis of retear risk and function. Methods PubMed, Embase, and SPORTDiscus were searched for all English-language, peer-reviewed studies between 2000 and the present, which analyzed relationships between patient-related factors and outcomes of rotator cuff repair. Studies that explicitly examined the effect of DLD on rotator cuff repair outcomes were chosen for inclusion. Included studies were assessed for methodological quality, and data were extracted for meta-analysis. Results Of the 3087 titles, 424 were screened by abstract, and 67 were reviewed in full. Inclusion criteria were met by 11 studies. Of these studies, 5 studies assessed retear, 2 studies measured function, 3 studies reported both retear and function, and 1 study evaluated the risk of retear necessitating a revision surgery. The studies report no significant difference in functional outcomes. Meta-analysis revealed that DLD patients had a significantly higher risk of retear after primary rotator cuff repair (odds ratio 1.32, 95% confidence interval 1.06-1.64). Conclusion DLD leads to an increased risk of retear after rotator cuff repair, although function appears to be unimpaired. DLD should be considered among other risk factors when counseling patients regarding expected rotator cuff repair outcomes.

Abstract
Rotator cuff repair has benefitted from many technologic advances including the advent of arthroscopy, improved implant materials, and refined repair techniques. Despite our efforts to improve the science of rotator cuff repair, clinical advances have lagged far behind. Graft augmentation of rotator cuff repairs is an emerging and heterogeneous field that has significantly improved both healing rates and patient-reported metrics in initial data reporting. Treatment algorithms that guide the use of this novel surgical modality are of benefit to practicing orthopaedic surgeons.

Abstract
We provide our algorithm for tissue augmentation of rotator cuff repairs based on the current available evidence regarding rotator cuff healing. A variety of factors are associated with healing following rotator cuff repair. Increasing tear size and retraction as well as severe fatty degeneration have been associated with worsening rates of tendon healing. Given the correlation between tendon healing and postoperative outcomes, it is important to identify patients at high risk for failure and to modify their treatment accordingly to minimize the risk of early biomechanical failure and maximize the potential for structural healing. One approach that may be used to improve healing is tissue augmentation. Tissue augmentation is the use of tissue patches and scaffolds to provide rotator cuff reinforcement. Surgical management for rotator cuff tears (RCTs) continues to be a challenging task in orthopaedic surgery today. Appropriate treatment measures require an in depth understanding and consideration of the patient's prognostic factors such as age, fatty infiltration of the rotator cuff muscles, bone mineral density, rotator cuff retraction, anteroposterior tear size, work activity, and degenerative changes of the joint. Using these factors within the Rotator Cuff Healing Index, we can determine a patient's surgical treatment that will yield the maximum healing rate. For nonarthritic RCTs, joint-preserving strategies should be first-line treatment options. For young, active patients with a reparable RCT and minimal fatty infiltration, a complete repair can be effective. For young patients with irreparable RCTs, superior capsular reconstructions, and tendon transfers are viable options. For elderly patients with low work activity, an irreparable RCT and significant fatty infiltration, a partial repair with or without graft augmentation can be attempted if minimal to no arthritic changes are seen. LEVEL OF EVIDENCE: Level V, expert opinion.

Abstract
Total shoulder arthroplasty is a rapidly growing field, with more procedures performed each year. An important aspect of shoulder arthroplasty surgery is the management of soft tissues. Good functional outcomes in shoulder arthroplasty are significantly dependent on the repair of the rotator cuff tendons and proper release of the shoulder capsule. The success of any shoulder arthroplasty is predicated upon the meticulous handling of these tissues. The surgeon's ability to execute appropriate soft tissue techniques will facilitate easier surgery by increasing exposure and lead to better outcomes for the patient.

Knee Surg Sports Traumatol Arthrosc 2022; 30:2123-2129. [PMID: 35022825 DOI: 10.1007/s00167-021-06831-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2021] [Accepted: 12/02/2021] [Indexed: 01/08/2023]
Abstract
PURPOSE The purpose of this study was to evaluate clinical outcomes and tendon integrity on magnetic resonance imaging (MRI) of chronic posterosuperior rotator cuff tears treated with single-row tensionless repair and subacromial balloon spacer as protection with a minimum follow-up of 2 years. The hypothesis of this study was that this procedure would have acceptable clinical outcomes and tendon-healing rate without increased complications. METHODS This is a retrospective study of patients with chronic posterosuperior rotator cuff tears repaired with a single-row technique protected with a subacromial balloon device. Patients were followed up for a minimum of 2 years. Clinical outcomes were evaluated with American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) and Numerical Rating Scale (NRS) for pain. MRI study was obtained likewise after at least 2 years to assess tendon-healing rate. Statistical comparison was performed between pre-operative and at least 2-year clinical and imaging follow-up. RESULTS Thirty-two patients were included in the study with a mean follow-up of 27 ± 7 (range 24-48). The mean age of this cohort was 58 ± 6 (range 41-66) including 15 males and 17 females. The tear size was on average 2.3 cm (range 2-4) and a mean of 2.1 triple-loaded anchors were used (range 2-3). The ASES score significantly increased from a mean of 39 ± 12 points to a mean of 89 ± 12 at the final follow-up (P < 0.001). Similarly, pain significantly reduced from a mean pre-operative NRS of 6.8 ± 1.4 to 0.8 ± 1.5 at the final follow-up (P < 0.001). MRI scans showed that repair occurred in 26 patients (81.3%). Significant higher ASES score was reached at final follow-up in patients with a "healed" (Sugaya I-III) tendon when compared to patients with an evidence of tendon discontinuity on MRI study (Sugaya IV-V), 93 ± 9 and 74 ± 13, respectively (P < 0.001). CONCLUSIONS Arthroscopic repair of chronic posterosuperior rotator cuff tears using a single-row tensionless repair and subacromial spacer as protection resulted in an 81.3% of tendon integrity at a mean follow-up of 27 months. Clinical outcomes and pain scores significantly improved without severe complications reported after a minimum follow-up of 2 years. LEVEL OF EVIDENCE III.

Front Physiol 2022; 13:801829.

Abstract
The rabbit supraspinatus is a useful translational model for rotator cuff (RC) repair because it recapitulates muscle atrophy and fat accumulation observed in humans after a chronic tear (the “first hit”). However, a timeline of RC tissue response after repair, especially with regard to recent evidence of muscle degeneration and lack of regeneration, is currently unavailable. Thus, the purpose of this study was to characterize the progression of muscle and fat changes over time after the repair of a chronic RC tear in the rabbit model. Two rounds of experiments were conducted in 2017–2018 and 2019–2020 with N = 18 and 16 skeletally mature New Zealand White rabbits, respectively. Animals underwent left supraspinatus tenotomy with repair 8 weeks later. The unoperated right shoulder served as control. The rabbits were sacrificed at 1-, 2-, 4-, and 8-weeks post-repair for histological and biochemical analysis. Atrophy, measured by fiber cross-sectional area and muscle mass, was greatest around 2 weeks after repair. Active muscle degeneration peaked at the same time, involving 8% of slide areas. There was no significant regeneration at any timepoint. Fat accumulation and fibrosis were significantly increased across all time points compared to contralateral. Statement of Clinical Significance: These results demonstrate model reproducibility and a “second hit” phenomenon of repair-induced muscle atrophy and degeneration which partially recovers after a short time, while increased fat and fibrosis persist.

Reverse shoulder arthroplasty for rotator cuff tears with and without prior failed rotator cuff repair: A large-scale comparative analysis. J Orthop 2022; 31:1-5. [PMID: 35299693 PMCID: PMC8920866 DOI: 10.1016/j.jor.2022.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Accepted: 03/06/2022] [Indexed: 10/18/2022] Open
Abstract
Background Large-scale data assessing the effect of a prior failed rotator cuff repair (RCR) on the outcome of reverse shoulder arthroplasty (RSA) is currently lacking. Therefore, this study aimed (1) to assess the course of patients undergoing RCR, specifically focusing on the need for conversion to RSA within two years, and (2) to compare outcomes following RSA performed for rotator cuff tears (RCTs) with and without prior RCR. Methods This retrospective cohort study included data from the CMS Data Set (2016-2018). For the first study objective, we included patients undergoing an RCR; these were followed for 24 months to identify a conversion to RSA. For the second study objective, we included RSAs for RCTs, stratified by those with and without a prior RCR (preceding 24 months). Outcomes (hospitalization cost, institutional post-acute care discharge, 90-day readmission and health resource utilization up to 6 months post-RSA) were compared between propensity score-matched groups. Results Out of 33,244 RCRs, 433 (1.3%) patients underwent RSA conversion within two years. Among 7534 RSA cases for RCTs, 245 (3.3%) had an RCR in the preceding two years. In the propensity score analysis, except for a minimal increase in the number of physical rehabilitation visits (RR 1.10; p = 0.0009), no differences were observed between those with and without prior RCR in terms of other RSA outcomes. These included hospitalization cost, discharge to institutional post-acute care facility, 90-day readmission and 6-month post-op cost. Conclusion Rotator cuff repair in elderly patients, when utilizing currently employed indication criteria, results in low conversion rates to RSA within 2 years postoperatively. Furthermore, large dataset outcomes after RSA for RCT such as cost, post-acute care discharge, physical rehabilitation, and readmission rates appear not to be negatively affected by the presence of a prior RCR.

Abstract
PURPOSE The purpose of this study was to evaluate the short-term patient-reported outcomes of superior capsular reconstruction (SCR) and identify factors contributing to the success or failure of the procedure at 2 years. METHODS A retrospective review was performed on data prospectively collected from the Surgical Outcomes System database. Patient-reported outcomes (PROMs) including American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) were evaluated at a minimum of 2 years postoperatively and reported using a minimal clinically important difference (MCID) and the percent of maximal possible improvement (MPI). In addition, preoperative and intraoperative variables were evaluated in patients with and without a postoperative improvement in ASES and SANE scores meeting the threshold of MCID. RESULTS Two-year follow-up data were available for 350 patients. Statistically significant improvements were noted in all PROMs at 2-year follow-up. In total, 240 patients (68.8%) achieved an MCID improvement of >17.5 in ASES score, and 185 patients (52.9%) achieved an MCID of >29.8 improvement in the SANE score. Primary SCRs were associated with a higher MPI in the ASES score (60.1% ± 39.8% vs 40.4% ± 47.9%; P = .025) and VR-12 physical score (14.0% ± 13.8% vs 8.0% ± 14.7%; P = .028) compared to revision repairs. Only diabetes was identified as a predictor of SANE score improvement (64.5% vs 62.2%; P = .041). CONCLUSIONS SCR is associated with improvement in patient-reported outcomes at short-term follow-up, with 53% to 69% of patients achieving an improvement considered to meet the MCID. Greater improvement is expected when SCR is performed as a primary procedure rather than as a revision procedure for failed rotator cuff repair.

Abstract
BACKGROUND Retear after arthroscopic rotator cuff repair (ARCR) consistently challenges medical staff and patients, and the incidence of retear after surgery is 10%-94%. The purpose of this study was to identify the risk factors that cause retear after ARCR and provide theoretical guidance for clinical intervention to reduce the occurrence of postoperative rotator cuff retear. METHODS The protocol for this meta-analysis was registered with PROSPERO (CRD42021225088). PubMed, Web of Science, and Embase were searched for observational studies on risk factors for rotator cuff retear after arthroscopic repair. Meta-analytical methods were used to determine the odds ratio or weighted mean difference of potential risk factors related to postoperative rotator cuff retear. Stata 15.1 was used to quantitatively evaluate the publication bias of the statistical results. RESULTS Fourteen studies from 6 countries with a total of 5693 patients were included. The meta-analysis revealed that the risk factors for retear after rotator cuff repair were age, body mass index, diabetes, subscapularis and infraspinatus fatty infiltration, symptom duration, bone mineral density, tear length, tear width, tear size area, amount of retraction, critical shoulder angle, acromiohumeral interval, distance from the musculotendinous junction to the glenoid, operative duration, biceps procedure, and postoperative University of California Los Angeles shoulder score. CONCLUSION These findings can help clinical medical staff identify patients who are prone to retear early after arthroscopic repair and develop targeted prevention and treatment strategies for modifiable risk factors, which are of great significance for reducing the occurrence of rotator cuff retear after ARCR.

Abstract
Background Osteoporosis is an important clinical factor for tendon healing after arthroscopic rotator cuff repair (ARCR). Conventional dual energy X-ray absorptiometry (DXA) of the hip and lumbar spine (LS) does not represent proximal humeral bone mineral density (BMD). Theoretically, direct measurement of the BMD of the proximal humerus is the best method; however, it is not popular and is non-standardized. Therefore, we evaluate whether the trabecular bone score (TBS) using LS DXA would represent proximal humeral BMD. Methods Conventional hip and LS DXA and proximal humeral BMD were measured in 212 consecutive ARCR patients, and TBS was calculated using LS DXA. Comparative analysis between the affected and contralateral asymptomatic shoulders was done; moreover, correlation analysis was conducted to evaluate the representativity of TBS for proximal humeral BMD. Regression analysis was performed to elucidate the risk factor of intraoperative suture anchor failure (ISAF). Results BMDs of the affected shoulder were significantly lower than those of the contralateral side (all P<0.05). TBS failed to present a strong correlation with proximal humeral BMD (correlation coefficients 0.155–0.506, all P<0.05), and the BMD of the greater tuberosity (GT) of the proximal humerus was revealed to be a sole risk factor for ISAF (odds ratio, 0.01, P=0.020). Conclusions TBS and conventional hip and LS DXA did not represent proximal humeral BMD. Furthermore, among the various radiological measurements, the BMD of the GT was a sole risk factor of ISAF. Therefore, further research for the direct measurement of proximal humeral BMD is mandatory to predict proximal humeral focal osteoporosis.

Abstract
BACKGROUND Retear or nonhealing of a surgically repaired rotator cuff is common, but the determinants of retear are poorly understood. We aimed to determine the relationship between preoperative and intraoperative factors and retear rate following rotator cuff repair and to formulate a predictive model based on this relationship, including any interaction effects between tear size, patient age, and surgical experience in contributing to the retear rate. METHODS We performed a post hoc analysis of prospectively collected data from 1962 consecutive patients who underwent a primary arthroscopic single-row rotator cuff repair performed by the senior author from 2007 through 2018 and postoperatively returned for 6-month follow-up ultrasonography. RESULTS Multiple logistic regression analysis revealed anteroposterior tear length to be the most important independent predictor of retear (Wald statistic, 90; P < .001). Other independent predictors included case number (Wald statistic, 59; P < .001), patient age at surgery (Wald statistic, 30; P < .001), and type of hospital (public vs. private) (Wald statistic, 17; P < .001). The data indicated that following rotator cuff repair, there was a 4-fold increase in the retear rate as the anteroposterior tear size increased from 1 cm to 3 cm; a 8-fold decrease when comparing case number 1000 with case number 3000; a 2-fold increase as patient age increased from 50 years to 70 years; and a 3-fold increase when comparing surgery performed in a public hospital vs. a private hospital. The area under the receiver operating characteristic curve was 0.81 (95% confidence interval, 0.78-0.84), indicating that our equation could predict 81% of retears. CONCLUSIONS Anteroposterior tear length was the most important independent predictor of retear or nonhealing. Other predictive factors included case number, patient age at surgery, and hospital type. The predictive effect of anteroposterior tear length, patient age, and case number in contributing to retear was additive. Our regression equation may be used to calculate patient rotator cuff retear risk at 6 months after repair.

Significance of the acromiohumeral distance on stress radiography for predicting healing and function after arthroscopic repair of massive rotator cuff tears. J Shoulder Elbow Surg 2021; 30:e471-e481.

Abstract
BACKGROUND A decreased acromiohumeral distance (AHD) is commonly detected in patients with massive rotator cuff tears (mRCTs). Most studies evaluating fixed humeral elevation have used preoperative or postoperative standardized radiography and not stress radiography. This study aimed to evaluate the predictive role of the preoperative AHD measured using stress radiography (AHD_stress) in rotator cuff healing and function after arthroscopic repair of mRCTs. METHODS The data of 113 patients who underwent arthroscopic repair of mRCTs were analyzed. Postoperative cuff integrity was evaluated using magnetic resonance imaging at 1 year, and shoulder function was evaluated at a mean of 34.9 ± 17.8 months (range, 24-92 months) postoperatively. Forty-seven patients showed healing failure. Propensity score matching (1-1) was performed between the healed group and healing failure group. Thirty-eight patients in each group were matched in the final analysis. The AHD and AHD_stress were defined as the shortest distances from the inferior acromion to the superior humerus on standard anteroposterior radiography and stress radiography (5.4-kg weight applied inferiorly in a neutral position), respectively. The AHD difference (AHD_diff) was defined as the difference between the AHD and AHD_stress values. Receiver operating characteristic curve analysis was performed to determine cutoff values for significant variables. RESULTS No difference in the mean preoperative AHD was found between the healed group (7.5 ± 2.0 mm) and healing failure group (6.9 ± 2.2 mm, P = .234). The AHD_diff value was significantly higher in the healed group (4.4 ± 2.1 mm) than in the healing failure group (3.0 ± 2.0 mm, P = .002; cutoff, 3.2 mm). Patients with an AHD_diff value ≥ 3.2 mm showed a lower healing failure rate (28.9% vs. 71.1%, P < .001) and higher functional scores than patients with an AHD_diff value < 3.2 mm. The AHD_diff value was higher in patients with an American Shoulder and Elbow Surgeons (ASES) score ≥ 80 (4.9 ± 1.9 mm) than in those with an ASES score < 80 (3.1 ± 2.1 mm, P = .024). Among patients with healing failure, only the postoperative AHD showed a significant difference between those with an ASES score ≥ 80 (7.0 ± 2.5 mm) and those with an ASES score < 80 (4.8 ± 2.1 mm, P = .009; cutoff, 4.8 mm). CONCLUSION A reducible AHD, which increased by ≥ 3.2 mm under stress radiography, can be a favorable predictor of rotator cuff healing and function after arthroscopic repair of mRCTs. Our findings suggest that this new and simple radiologic parameter should be considered preoperatively and would be helpful to determine appropriate treatment strategies.

Abstract
Causes of failure after arthroscopic rotator cuff repair include patient factors, tear factors, and surgical factors. Failure may occur at the suture-tendon interface, the bone-tendon interface, or the bone-anchor interface. Low bone mineral density (BMD) in the greater tuberosity has been reported as a prognostic factor for recurrent tears following rotator cuff repair, and although most studies suggest the tendon-to-suture interface as the "weakest link," patients with low BMD may have lower suture anchor pull-out strength. A potential alternative cause of failure is the suture cutting through the greater tuberosity bone in patients with low BMD. Knotless suture bridge constructs or single-row constructs may be more susceptible to a suture cutting through the bone. The knotted suture bridge technique, wherein the medial mattress sutures are tied, may to some extent "shield" against complete cut-through. When bone quality appears poor, a common response is to change the type of anchor, size of anchor, or the location of the anchor. Other factors, such as bone preparation, suture type, suture tensioning, and anchor type (e.g., internal vs external locking), may all potentially affect suture cutting through weak bone.
