J Shoulder Elbow Surg 2024; 33:e465-e477. [PMID: 38642872 DOI: 10.1016/j.jse.2024.03.014] [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: 01/14/2024] [Revised: 02/18/2024] [Accepted: 03/03/2024] [Indexed: 04/22/2024]
Abstract
BACKGROUND To identify and quantify the factors associated with the reparability of rotator cuff tears (RCTs). METHODS PubMed, Scopus, and Web of Science databases were searched for clinical studies published in English focusing on RCT reparability by using the keywords "rotator cuff tear" and "reparability". A meta-analysis was conducted if ≥3 studies examined the same factor and provided enough data to assess RCT reparability. Quality assessment was completed using the quality assessment of diagnostic accuracy studies tool. RESULTS Eighteen studies (2700 patients) were enrolled and 26 factors were included in the meta-analysis. The dichotomous variables associated with irreparability were Patte stage 3 (odds ratio (OR): 8.0, 95% confidence interval [CI]: 4.3-14.9), massive tear vs. large tear (OR: 3.1, 95% CI: 1.3-7.2), Goutallier stage for each tendon, and tangent sign (OR: 11.1, 95% CI: 4.3-28.4). The continuous variables associated with irreparability were age (mean difference (MD): 3.25, 95% CI: 1.4-5.1), mediolateral tear size (MD: 12.3, 95% CI: 5.8-18.9), anteroposterior tear size (MD: 10.4, 95% CI: 5.2-15.6), acromiohumeral distance on X-ray (MD: -2.3, 95% CI: -3.0 to -1.6) and magnetic resonance imaging (MD: -1.8, 95% CI: -2.8 to -0.9), and inferior glenohumeral distance on magnetic resonance imaging (MD: 2.2, 95% CI: 1.4-3.0). CONCLUSION This study revealed that older age, larger tear size, severe fatty infiltration, muscle atrophy, and advanced superior migration of the humeral head were strongly associated with irreparable RCTs. Conversely, clinical symptoms provided limited information for predicting reparability. Additionally, the tangent sign emerged as a powerful and simple tool for individual prediction, and several quantitative scoring systems also proved useful.

Abstract
Rotator cuff tear is a common source of pain and disfunction in shoulder, with prevalence increasing with age. Nonsurgical treatment is adequate for many patients; however, for those for whom surgical treatment is indicated, rotator cuff repair provides reliable pain relief and good functional results. However, massive and irreparable tears due to tear size, tendon retraction, muscle atrophy, fatty infiltration are a significant challenge for surgeons. Whenever irreparable tears coexist with cartilage degeneration/arthritis (rotator cuff arthropathy), the indication of reverse shoulder arthroplasty is the golden standard. However, in young patients without arthritis, joint preserving procedures, from debridement to muscle transfers, are preferred. Choosing the most appropriate treatment is not quite established in literature, each treatment modality present particular indications, advantages and disadvantages.

Abstract
OBJECTIVE To explore the treatment experiences of those diagnosed with large to massive rotator cuff tears and the perspectives of healthcare practitioners providing their care. DESIGN A qualitative descriptive study using reflexive thematic analysis. SETTING In-person focus groups were undertaken in a clinical setting (private practice [n = 1]; public outpatient [n = 2]). Semi-structured interviews were conducted online via Microsoft Teams. PARTICIPANTS Patients diagnosed with these tears (n = 12) and healthcare practitioners (n = 11). RESULTS Two interlinking themes were identified based on the care received and provided for patients with symptomatic large to massive rotator cuff tears:1) Positive treatment experiences and management: Education, clear communication and reassurance around prognosis were the foundation of positive patient-clinician care. Sub-themes of pain relief, exercise prescription and confidence in their pathway underpinned this experience. This proficiency in care was affirmed by some healthcare practitioners who spoke about the importance of confidence and experience in their management plan even in times of poor progress.2) Negative treatment experiences and management: Uncertainty, delays and exacerbation of pain flawed the patient-clinician care. Sub-themes of inappropriate pain relief, inappropriate exercise prescription and uncertainty impacted their care. Some healthcare practitioners acknowledged knowledge gaps led to uncertainty especially when choosing the next step of care and were quick to escalate care to deflect this uncertainty. CONCLUSIONS The findings suggest discordance exists between the patient's experiences and expectations when the delivery of care was by less experienced and confident healthcare practitioners in the management of this condition. This highlights the need for improved education and support for healthcare practitioners.

Abstract
Background Superior migration of the humeral head is common in large and massive rotator cuff tears (RCTs). Humeral heads migrate superiorly according to an increase in the RCT size; however, the relevance of the remaining cuff has not been elucidated. This study investigated the relation between superior migration of the humeral head and the remaining rotator cuff, especially the teres minor (TM) and subscapularis (SSC), in RCTs involving tears and atrophy of the infraspinatus (ISP). Methods Plain anteroposterior radiographic and magnetic resonance imaging examinations were performed on 1345 patients between January 2013 and March 2018. A total of 188 shoulders with tears of the supraspinatus and ISP with atrophic ISP were evaluated. Gradings of superior migration of the humeral head and osteoarthritic change were evaluated using the acromiohumeral interval, Oizumi classification, and Hamada classification on plain anteroposterior radiographs. The cross-sectional area of the remaining rotator cuff muscles was evaluated using oblique sagittal magnetic resonance imaging. The TM was classified as hypertrophic (H) and normal and atrophic (NA). The SSC was classified as nonatrophic (N) and atrophic (A). All shoulders were classified as groups A (H-N), B (NA-N), C (H-A), and D (NA-A). Age- and sex-matched patients with no cuff tears were also enrolled (control). Results The acromiohumeral intervals of the control group and groups A-D were 11.4 ± 2.4, 9.5 ± 3.8, 7.8 ± 4.1, 7.2 ± 4.0, and 5.4 ± 3.5 mm (84, 74, 64, 21, and 29 shoulders, respectively), with significant differences between groups A and D (P < .001) and groups B and D (P = .016). Grade 3 of the Oizumi classification and grades 3, 4, and 5 of the Hamada classification were significantly higher in group D than in others (P < .001). Conclusion The group showing hypertrophic TM and nonatrophic SSC prevented significantly migration of the humeral head and cuff tear osteoarthritis compared to the group showing atrophic TM and SSC in posterosuperior RCTs. The findings indicate that the remaining TM and SSC may prevent superior migration of the humeral head and progression of osteoarthritic change in RCTs. In treating patients with large and massive posterosuperior RCTs, the status of the remaining TM and SSC muscles should be assessed.

Abstract
This study aimed to compare the outcomes of arthroscopic rotator cuff repair (ARCR) surgery between younger and older patients. We performed this systematic review and meta-analysis of cohort studies comparing outcomes between patients older than 65 to 70 years and a younger group following arthroscopic rotator cuff repair surgery. We searched MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and other sources for relevant studies up to 13 September 2022, and then assessed the quality of included studies using the Newcastle-Ottawa Scale (NOS). We used random-effects meta-analysis for data synthesis. The primary outcomes were pain and shoulder functions, while secondary outcomes included re-tear rate, shoulder range of motion (ROM), abduction muscle power, quality of life, and complications. Five non-randomized controlled trials, with 671 participants (197 older and 474 younger patients), were included. The quality of the studies was all fairly good, with NOS scores ≥ 7. The results showed no significant differences between the older and younger groups in terms of Constant score improvement, re-tear rate, or other outcomes such as pain level improvement, muscle power, and shoulder ROM. These findings suggest that ARCR surgery in older patients can achieve a non-inferior healing rate and shoulder function compared to younger patients.

Abstract
PURPOSE To evaluate the effect of biceps tenotomy on humeral migration and clinical outcomes in patients who underwent arthroscopic rotator cuff (RC) repair. METHODS This is a retrospective study of 60 patients who underwent arthroscopic RC repair. Patients were divided into two groups, whether they underwent concomitant biceps tenotomy or not. The group underwent concomitant biceps tenotomy, tenotomy ( +), or not, tenotomy (-). Clinical and functional outcomes were performed using the American Shoulder and Elbow Surgeons (ASES), the University of California-Los Angeles (UCLA) scoring system. Radiological evaluation was performed in X-rays and magnetic resonance imaging (MRI), measuring the acromiohumeral distance (AHD), humeral migration (HM) and upper migration index (UMI). RESULTS There was no significant difference between the groups in terms of patient characteristics. The follow-up period was 30.9 ± 8.7 months in the tenotomy ( +) group and 34.9 ± 8.2 months in the tenotomy (-) group with no significant difference. Postoperative ASES score improved significantly in the tenotomy ( +) group compared to the tenotomy (-) group (91.2 ± 4.7, 80.8 ± 18.7, respectively, p = 0.005). There was a significant difference in postoperative AHD, HM and UMI values (MRI; p = 0.003, p = 0.017, p = 0.025; X-ray; p = 0.049, p = 0.002, p = 0.010, respectively). The post-pre difference increase of AHD [MRI for tenotomy( +): 0.14 ± 0.86 and tenotomy(-): 0.91 ± 0.85, p = 0.001; X-ray for tenotomy( +): 0.61 ± 0.43 and tenotomy(-): 1.12 ± 0.7, p = 0.001] and UMI [MRI for tenotomy( +): 0.005 ± 0.05 and tenotomy(-): 0.04 ± 0.06, p = 0.006; X-ray for tenotomy( +): 0.01 ± .064 and tenotomy(-): 0.12 ± 0.37, p = 0.110] values were higher in the tenotomy (-) group compared to the tenotomy ( +) group while HM values decreased more in the tenotomy (-) group. [MRI for tenotomy ( +): -0.19 ± 1.07 and tenotomy (-): -0.79 ± 1.52, p = 0.079; X-ray for tenotomy ( +): -0.27 ± 0.54 and tenotomy (-): -1.006 ± 1.83, p = 0.040]. CONCLUSION After short-term follow-up, the humeral head was positioned higher in patients who underwent LHBT tenotomy compared to patients without tenotomy. However, it seems to affect clinical outcomes during this period positively. LEVEL OF EVIDENCE Level 3.

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

Abstract
BACKGROUND Adhesive capsulitis is a common shoulder disorder inducing joint capsule fibrosis and pain. When combined with rotator cuff tear (RCT), treatments can be more complex. Currently, targeted therapy is lacking. Since adhesive capsulitis is reported to be related to circulating materials, we analyzed the contents and biology of circulating exosomes from RCT patients with and without adhesive capsulitis, in an attempt to developing a targeting treatment. METHODS Samples from a consecutive cohort of patients with RCT for surgery were collected. Circulating exosomal miRNAs sequencing were used to detect differentially expressed miRNAs in patients with and without adhesive capsulitis. For experiments in vitro, Brdu staining, CCK-8 assay, wound healing test, collagen contraction test, real-time quantitative polymerase chain reaction, and western blot were conducted. Histological and immunofluorescent staining, and biomechanical analysis were applied in a mouse model of shoulder stiffness. The characteristics of liposomes loaded with siRNA were measured via dynamic light scattering or electron microscopy. RESULTS Circulating exosomal miRNAs sequencing showed that, compared to exosomes from patients without adhesive capsulitis, miR-142 was significantly up-regulated in exosomes from adhesive capsulitis (Exo-S). Both Exo-S and miR-142 could inhibit fibrogenesis, and the anti-fibrotic effect of Exo-S relied on miR-142. The target of miR-142 was proven to be transforming growth factor β receptor 1 (Tgfbr1). Then, liposomes were developed and loaded with si-Tgfbr1. The si-Tgfbr1-loading liposomes exhibited promising therapeutic effect against shoulder stiffness in mouse model with no evidence toxicity. CONCLUSION This study showed that, in RCT patients with adhesive capsulitis, circulating exosomes are protective and have anti-fibrotic potential. This effect is related to the contained miR-142, which targets Tgfbr1. By mimicking this biological function, liposomes loaded with si-Tgfbr1 can mitigate shoulder stiffness pre-clinically.

Abstract
PURPOSE The purpose of this study is to describe rotator cuff muscle stiffness in patients with different degrees of rotator cuff tear (RCT) severity and to assess its predictive ability for RCT reparability. METHODS One hundred and thirty-three consecutive patients who were scheduled to undergo arthroscopic shoulder surgery were prospectively enrolled. Tendon retraction, fatty infiltration, and muscle atrophy were evaluated using magnetic resonance imaging. Shear modulus of supraspinatus (SSP) and infraspinatus (ISP) muscles were measured by ultrasound shear wave elastography (SWE). The tear size and reparability were determined intraoperatively. RESULTS There were 97 patients in RCT group and 36 patients in control group. Bilateral shear modulus discrepancy (Δshear modulus) was used to represent rotator cuff stiffness. Severely fatty-infiltrated rotator cuff muscles possessed a significantly higher stiffness compared with their counterparts (SSP: CI 27.8-31.8 vs. 13.5-15.6 kPa, ISP: CI 33.2-38.1 vs. 8.8-11.2 kPa, p < 0.001). The same trend applied to muscles with distinct tendon retraction (SSP: CI 27.7-32.3 vs. 10.9-14.9 kPa, ISP: CI 33.2-38.6 vs. 6.5-11.0 kPa, p < 0.001) and obvious muscle atrophy (SSP: CI 27.9-32.1 vs. 13.6-15.8 kPa, ISP: CI 32.9-38.2 vs. 9.0-11.7 kPa, p < 0.001). Irreparable massive RCT (MRCT) patients had significantly stiffer SSP (CI 27.7-31.9 vs. 13.5-16.5 kPa, p < 0.001) and ISP (CI 33.5-37.8 vs. 10.3-14.8 kPa, p < 0.001) than reparable MRCT. The Δshear modulus of the ISP was a highly accurate predictor of RCT reparability. A cutoff value of 18.0 kPa had a sensitivity of 100% and specificity of 98.8% for irreparable MRCT. CONCLUSION Ultrasound SWE-derived rotator cuff muscle stiffness is closely correlated with RCT size and severity. LEVEL OF EVIDENCE I.

Intra-articular injection versus interscalene brachial plexus block for acute-phase postoperative pain management after arthroscopic shoulder surgery. J Orthop Sci 2022; 28:560-566. [PMID: 35184956 DOI: 10.1016/j.jos.2022.01.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Revised: 08/25/2021] [Accepted: 01/05/2022] [Indexed: 02/09/2023]
Abstract
BACKGROUND The minimally invasive approach of arthroscopic shoulder surgery is beneficial; however, for optimal outcomes, perioperative pain management is essential. This cross-sectional study aimed to examine the analgesic effectiveness of intra-articular injection (IA) versus interscalene brachial plexus block (ISPB) among patients treated with arthroscopic shoulder surgeries. METHODS We reviewed 100 consecutive patients who underwent shoulder arthroscopic surgery, of whom 50 each underwent IA (February 2019─January 2020; IA group) and ISPB (October 2018─July 2019; ISPB group). The primary outcome was the postoperative pain score measured using a Wong-Baker FACES Pain Rating Scale preoperatively and at 2, 6, 12, 24, and 48 h postoperatively. We performed multiple regression analysis to examine whether IA/ISPB selection is associated with acute-phase postoperative pain and adjusted for intra-articular injection, interscalene brachial plexus block, postoperative pain management, arthroscopic shoulder surgery, IA with 10 mg of morphine previously reported prognostic factors for postoperative pain (e.g., surgical procedures, operative time, older age, and preoperative pain). Furthermore, we examined induction time, total pentazocine dosage, and total postoperative nausea and vomiting (PONV) events. RESULTS There were no significant differences between the IA and ISPB groups in perioperative pain control during the acute-phase periods (p = 0.12, repeated analysis of variance). The difference in anesthesia method was not a prognostic factor for acute-phase postoperative pain (p = 0.11). The IA group (15.06 ± 4.00 min) had a significantly shorter mean anesthesia induction time than the ISPB group (29.23 ± 9.22 min) (p = 0.0001). There was no significant between-group difference in the total pentazocine dosage during the first 7 days (p = 0.3934) postoperatively. PONV was observed in eight (17.0%) and two (4.2%) patients in the IA and ISPB groups, respectively. There was no significant between-group difference in the PONV incidence (p = 0.1582). CONCLUSIONS There was no significant difference in acute-phase postoperative pain management between the IA and ISPB groups. The induction time was significantly shorter in IA.

Association between type of rotator cuff tear and functional outcomes in patients with massive and irreparable rotator cuff tear: A pre-post intervention study. J Shoulder Elbow Surg 2021; 30:1393-1401. [PMID: 32920107 DOI: 10.1016/j.jse.2020.08.034] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 08/07/2020] [Accepted: 08/17/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND The aim of this study was to analyze: (1) the differences in the pre-post change in functional outcomes after a physical therapy program by the type of massive and irreparable rotator cuff tear (MIRCT) controlling for potential confounders, and (2) the influence of lifestyle behaviors and demographic and tear tendon characteristics on function in patients over 60 years of age with conservatively treated MIRCT. MATERIALS AND METHODS In this pre-post intervention study, 92 patients were prospectively recruited at the Clinical Hospital San Borja Arriaran, with atraumatic MIRCT, between 60 and 75 years of age (mean: 67.9 ± 4.5 years), and the mean of length of symptoms was 16.5 months (±5.7 months). Patients received a physical therapy program consisting of manual therapy and a specific exercise program of 2 sessions per week for 12 weeks. The imaging findings were performed by 2 medical radiologists who classified the rotator cuff tear according to the criteria proposed by Collins. Shoulder function, upper limb function, and pain intensity were assessed with the Constant-Murley; Disabilities of the Arm, Shoulder, and Hand; and visual analog scale (VAS), respectively. Analysis of covariance models were estimated to assess differences in MIRCT categories between functional outcomes. Multiple regression model analysis was used for the association between the change in functional outcomes and lifestyle behaviors, and demographic and tear tendon characteristics. RESULTS The results showed no pre-post change in functional outcomes by type of MIRCT in all models (P > .05). There is an association between length of symptoms (P = .000), and the baseline values of the 3 functional measures (P = .000) are associated with changes in Constant-Murley; Disabilities of the Arm, Shoulder, and Hand; and VAS. In addition, changes in VAS are associated with body mass index (BMI) (P = .000), and changes in Constant-Murley are associated with gender (P = .023), BMI (P = .000), and tobacco consumption (P = .000). CONCLUSION There is no difference in functional outcomes by type of MIRCT after a physical therapy program controlling for potential confounders. In addition, there is an association of length of symptoms with all functional outcomes, an association of BMI with VAS and Constant-Murley questionnaire, and an association between tobacco consumption and Constant-Murley questionnaire. Our results could influence the orthopedic surgeon's decisions; thus, not predicting the functional outcome through imaging findings could lead clinicians to reconsider the need for surgery in the treatment algorithm in patients over 60 years with MIRCT. In addition, demographic characteristics and lifestyle behaviors might be considered within the patient's evaluation and follow-up to decide on surgical interventions and evaluate the clinical course of the disease. Further studies measuring additional variables and longer follow-up are needed to confirm these results.

Abstract
BACKGROUND The effect of patient age on functional improvement after arthroscopic rotator cuff repair (ARCR) is still a matter of debate. The purpose of this study was to evaluate the clinical midterm results after ARCR in patients who were 75 years or older at the time of surgery. METHODS A total of 31 shoulders in 30 patients older than 75 years at the time of surgery underwent ARCR for a degenerative full-thickness rotator cuff tear (RCT) between 2010 and 2016. Among those, 23 shoulders in 22 patients (74%) with a mean age at time of surgery of 77 ± 2 years (range, 75-82 years) were followed up after a mean of 7 ± 2 years (range, 3-9 years). Clinical assessment included the Western Ontario Rotator Cuff (WORC) index as well as patient satisfaction, the Subjective Shoulder Value (SSV), Simple Shoulder Test (SST), and the American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) score. RESULTS Overall, patient satisfaction was excellent, as everybody stated to be very satisfied with the surgery. Neither any complication nor revision surgery occurred during the study period. At final follow-up, the mean WORC index was 88% ± 15%. The mean SSV was comparable between the affected shoulder (90% ± 15%) and the contralateral side (87% ± 15%) (P = .235). The mean SST score was 10 ± 2 points and the mean ASES score was 89 ± 17 points. CONCLUSION ARCR for symptomatic RCTs without advanced muscle degeneration in patients older than 75 years at the time of surgery provided good clinical results and high patient satisfaction at midterm follow-up.

Abstract
Objectives: The literature indicates that reduced acromiohumeral distance (AHD) and increased critical shoulder angle (CSA) are associated with large and massive rotator cuff (RC) tears which may not be amenable to a successful repair. The purpose of this study was to examine the overall accuracy of these two radiographic features in diagnosing significant RC pathology. Methods: This was a diagnostic study of patients with shoulder pain. To examine the overall accuracy of the measurements, the area under the Receiver Operating Characteristic curves (AUC) were calculated. The validity indices (sensitivity, specificity and likelihood ratios) examined the predictive value of specific cutoff categories of AHD<6 mm and the CSA >35°. Results: Data of 200 consecutive patients; mean age: 59(11), 117 males were used for analysis. There was a weak inverse correlation (r = 0.46) between the AHD and CSA. The AUCs for presence and size of RC tear and different stages of fatty infiltration of supraspinatus and infraspinatus muscles varied from fair to excellent for AHD and poor to good for CSA. Specificity was high for the cutoff categories of both AHD and CSA (>90%). The positive LRs were large for AHD and small to moderate for CSA. Conclusion: The AHD and CSA were reliably measured in the true AP radiographic view. Both radiographic features (AHD<6mm and CSA>35°) were able to confirm the presence of a major RC pathology. However, the AHD<6 mm, an acquired radiologic abnormality secondary to failure of the RC muscles/tendons had better measurement properties. This information is of value to primary care physicians, sports medicine specialists and advanced practice physiotherapists in their clinical decision making.

Abstract
BACKGROUND Bone mineral density at the humeral head is reduced in patients with chronic rotator cuff tears. Bone loss in the humeral head is associated with repair failure after rotator cuff reconstruction. Bisphosphonates (eg, zoledronic acid) increase bone mineral density. HYPOTHESIS Zoledronic acid improves bone mineral density of the humeral head and biomechanical properties of the enthesis after reconstruction of chronic rotator cuff tears in rats. STUDY DESIGN Controlled laboratory study. METHODS A total of 32 male Sprague-Dawley rats underwent unilateral (left) supraspinatus tenotomy with delayed transosseous rotator cuff reconstruction after 3 weeks. All rats were sacrificed 8 weeks after rotator cuff repair. Animals were randomly assigned to 1 of 2 groups. At 1 day after rotator cuff reconstruction, the intervention group was treated with a single subcutaneous dose of zoledronic acid at 100 µg/kg bodyweight, and the control group received 1 mL of subcutaneous saline solution. In 12 animals of each group, micro-computed tomography scans of both shoulders were performed as well as biomechanical testing of the supraspinatus enthesis of both sides. In 4 animals of each group, histological analyses were conducted. RESULTS In the intervention group, bone volume fraction (bone volume/total volume [BV/TV]) of the operated side was higher at the lateral humeral head (P = .005) and the medial humeral head (P = .010) compared with the control group. Trabecular number on the operated side was higher at the lateral humeral head (P = .004) and the medial humeral head (P = .001) in the intervention group. Maximum load to failure rates on the operated side were higher in the intervention group (P < .001). Cortical thickness positively correlated with higher maximum load to failure rates in the intervention group (r = 0.69; P = .026). Histological assessment revealed increased bone formation in the intervention group. CONCLUSION Single-dose therapy of zoledronic acid provided an improvement of bone microarchitecture at the humeral head as well as an increase of maximum load to failure rates after transosseous reconstruction of chronic rotator cuff lesions in rats. CLINICAL RELEVANCE Zoledronic acid improves bone microarchitecture as well as biomechanical properties after reconstruction of chronic rotator cuff tears in rodents. These results need to be verified in clinical investigations.

Abstract
Whether tendon regeneration can be induced using the umbilical cord as a whole-graft structure is unknown. In this study, we explored the potential for tendon regeneration induction using an umbilical cord graft in a rabbit model of patella tendon defects. In 52 of 54 New Zealand White rabbits, the central third of the patella tendons of both hind legs was removed to create tendon defects. The rabbits were randomly divided into four groups, nonfilling (empty defect), refilling (defect refilled with resected tendon portion), Wharton's jelly (WJ) outside (WJO; defect filled with umbilical cord graft, WJ side facing outward), and WJ inside (WJI; same as WJO with WJ side facing inward) groups. Four rabbits from WJO and WJI groups were sacrificed for human CD 105 evaluation 1 month after surgery. Further histological, biomechanical, and gene expression analyses were performed at 3 and 6 months after surgery. The untreated patella tendons in the remaining two rabbits were harvested as normal biomechanical controls. Histological evaluation showed that the formed tissue structure fibers in the tendon defect area were much denser and more mature in the WJI group than in all other groups. Biomechanical testing showed that the failure load of the final tissue structure was the highest in the WJI group. Real-time polymerase chain reaction indicated that the expression of most tendon-related genes was upregulated in the WJI group at 6 months after surgery. We concluded that umbilical cord grafting induces effective tendon regeneration, particularly when the WJ side faces inward.

Abstract
The postoperative retear rate of direct repair of massive rotator cuff tear has risen up to 40% because of the dissatisfied tendon-to-bone healing and poor regenerative potential of remnant rotator cuff tissue. A biological scaffold that connects the remnant rotator cuff tissue and bone might be a promising substitute. In the present study, we have developed a macroporous three-dimensional scaffold poly(ester-urethane)urea (PEUU), with self-fitting capability employing thermally induced phase separation (TIPS) technique. The scaffold provides oriented connected macropores for cells migration, and promoted tendon-to-bone healing on the basis of surgical repair. The scaffolds were characterized by scanning electron microscopy, stress-strain test and cell biocompatibility study. In vitro studies exhibited that PEUU scaffold with suitable elastic mechanical properties can better support proliferation and migration of rabbit bone mesenchymal stem cells (RBMSCs). After three months postreconstruction of massive rotator cuff tear in a rabbit model using PEUU scaffold, there was complete regeneration of rotator cuff with physical tendon-to-bone interface and continuous tendon tissue, as observed from histological analysis. Further, biomechanical testing demonstrated that rotator cuff induced by PEUU scaffold had no significant difference as compared to normal rotator cuff. This macroporous, mechanically matched scaffold is potentially suitable for the application in massive rotator cuff repair. In conclusion, this study demonstrates the high efficiency of the macroporous 3D scaffold with self-fitting capability in facilitating rotator cuff regeneration.

Park SH, Choi CH, Yoon HK, Ha JW, Lee C, Chung K. What can the radiological parameters of superior migration of the humeral head tell us about the reparability of massive rotator cuff tears? PLoS One 2020; 15:e0231843. [PMID: 32298371 PMCID: PMC7162485 DOI: 10.1371/journal.pone.0231843] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Accepted: 04/01/2020] [Indexed: 02/03/2023] Open
Abstract
Objective The interrelation and clinical utility of the parameters for superior migration of the humeral head, such as the acromiohumeral interval (AHI), inferior glenohumeral distance (IGHD), and upward migration index (UMI), in the management of massive rotator cuff tears are not clear. The objectives of this study were to identify the relation between AHI, IGHD, and UMI when measured with radiography and MRI and to determine whether superior migration can predict the irreparability of massive rotator cuff tears. Methods We retrospectively reviewed the files of 64 consecutive patients who underwent arthroscopic partial or complete repair for massive rotator cuff tears at our institution between August 2015 and August 2018. We recorded both radiography and MRI measurements of AHI, IGHD, and UMI, and further the tangent sign, fatty infiltration of the rotator cuff muscles, and the Patte grade. We performed correlation assessments and multiple logistic regression analysis to identify potential predictors of the reparability of massive rotator cuff tears. Results Thirty-five patients had partially reparable and 29 had completely reparable tears. Parameters measured with either radiography or MRI were highly correlated with each other. The radiographic measurements showed a moderate or low correlation with the MRI measurements. All parameters of superior migration of the humeral head on radiography and MRI, the tangent sign, fatty infiltration of the infraspinatus muscle, and the Patte grade showed significant differences between patients with partially and completely repaired tears. Among these, the independent predictors for irreparability was Patte grade = 3. Conclusion The AHI, IGHD, and UMI were highly correlated when measured with either radiography or MRI, but not when comparing their radiographic with their MRI values. Furthermore, they were not independent indicators of reparability in massive rotator cuff tears.

Anatomic shoulder parameters and their relationship to the presence of degenerative rotator cuff tears and glenohumeral osteoarthritis: a systematic review and meta-analysis. J Shoulder Elbow Surg 2019; 28:2457-2466. [PMID: 31353303 DOI: 10.1016/j.jse.2019.05.008] [Citation(s) in RCA: 33] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/25/2019] [Revised: 05/03/2019] [Accepted: 05/06/2019] [Indexed: 02/08/2023]
Abstract
BACKGROUND Scapular anatomy, as measured by the acromial index (AI), critical shoulder angle (CSA), lateral acromial angle (LAA), and glenoid inclination (GI), has emerged as a possible contributor to the development of degenerative shoulder conditions such as rotator cuff tears and glenohumeral osteoarthritis. The purpose of this study was to investigate the published literature on influences of scapular morphology on the development of degenerative shoulder conditions. METHODS A systematic review of the Embase and PubMed databases was performed to identify published studies on the potential influence of scapular bony morphology on the development of degenerative rotator cuff tears and glenohumeral osteoarthritis. The studies were reviewed by 2 authors. The findings were summarized for various anatomic parameters. A meta-analysis was completed for parameters reported in more than 5 related publications. RESULTS A total of 660 unique titles and 55 potentially relevant abstracts were reviewed with 30 published articles identified for inclusion. The AI, CSA, LAA, and GI were the most commonly reported bony measurements. Increased CSA and AI correlated with rotator cuff tears, whereas lower CSA appeared to be related to the presence of glenohumeral osteoarthritis. Decreased LAA correlated with degenerative rotator cuff tears. Five articles reported on the GI with mixed results on shoulder pathology. DISCUSSION Degenerative rotator cuff tears appear to be significantly associated with the AI, CSA, and LAA. There does not appear to be a significant relationship between the included shoulder parameters and the development of osteoarthritis.

Abstract
PURPOSE To evaluate the preliminary clinical outcomes and complications of superior capsule reconstruction (SCR) for irreparable rotator cuff tears. METHODS A systematic review of PubMed, MEDLINE, EMBASE, and Cochrane databases was performed using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies reporting clinical outcomes of irreparable rotator cuff tears managed by SCR were included. Clinical outcome analyses of pre- and postoperative range of motion, American Shoulder and Elbow Surgeons scores, visual analog scale pain scores, and acromiohumeral intervals (AHIs) were performed and reported as range or frequency. RESULTS Five studies (285 patients, 291 shoulders) of level III-IV evidence were included, with a weighted mean (± standard deviation) follow-up of 27.7 ± 17.3 months. Forward flexion improved from 91°-130° preoperatively to 147°-160° postoperatively, external rotation from 26°-41° to 41°-45°, and internal rotation from L4-L1 to L1. American Shoulder and Elbow Surgeons scores increased from 36-52.2 to 77.5-92, and visual analog scale pain scores decreased from 4.0-6.3 to 0.4-1.7. Radiographically, AHIs with acellular dermal allograft ranged from 4.5 to 7.1 mm preoperatively, improving to 7.6-10.8 mm immediately postoperation before decreasing to 6.7-9.7 mm by final follow-up. Complication and graft failure rates were 17.2% and 11.7%, respectively. CONCLUSIONS Preliminary results of SCR show consistent improvement in shoulder functionality and pain reduction. However, a decrease in postoperative AHIs indicates dermal allograft elongation and persistent superior migration of the humerus, potentially contributing to later graft failure. Studies with longer follow-up will be essential to evaluate the long-term utility of SCR in the treatment of irreparable rotator cuff tears. LEVEL OF EVIDENCE Level IV, systematic review of level III-IV studies.

Abstract
Background and aim of the work: It is recognised that a significant percetage of large and massive rotator cuff tears (RCT) cannot be anatomically repaired and this correlates with a worste outcome in terms of pain, active range of motion, increased incidence of retair. The aim of our work is to find reliable index on pre-operative MRI shoulder image to assist orthopaedist in surgical planning of rotatator cuff tears repair. Methods: We performed a retrospective study on a population on 131 patients undergoing arthroscopic cuff repair by a single expert surgeon. Pre-operative MRI images were evaluated by a single orthopaedist, trained on MRI shoulder images ad blinded to surgical outcome. For each magnetic resonance we evaluated the following 9 parameters: fatty Infiltration (FI), Patte Stage (PS), tear size measured in medial-lateral (ML) and anterior-posterior (AP) dimension, Tangent Sign (TS), Occupation Grade (OG), Acromion-Humeral Distance (AHD), Inferior Gleno-Humeral Distance (IGHD), Glenoid Version Angle (GVA). We divided population into two groups: patients who obtained a complete repair of RCT (n=110) and patients who obtained only a partial repair of RCT (n=21). For each MRI index we conducted statistical analysis (Student’s t test, Mann-Whitney U test, Shapiro-Wilk test, Chi-square test, Fisher exact test, ROC curves and maximum Youden index) to find a Cut Off value useful to predict partial repair. Results: We have found statistical significance in predicting partial repair on MRI mesurements of Fatty Infiltration (FI grade ≥3; test di Fisher p<0.001), Patte Stage (grade= 3; test di Fisher p<0.001), Tear size measured in ML (>36 mm; Mann-Whitney p<0.001), Positive Tangent Sign (Chi-quadro p<0.001; sensitivity 95,3%, specificity 83,6%), Occupation Grade (OG <0,46; t-test p<0.001). Acromion-Humeral Distance (AHD <7 mm), Inferior Gleno-Humeral Distance (IGHD >5 mm). Tear size measured in AP (>21 mm; Mann-Whitney p<0.001) seems to be dependent on the contextual size of the lesion in ML. We haven’t found statistical significance in predicting partial repair of Glenoid Version Angle. Conclusions: A systematic observation of seven independent MRI parameters (FI, PS, tear size ML, TS, OG, AHD, IGHD) can help the surgeon to predict the impossibility to obtain complete repair of RCT and to consider different surgical approach.
