ABSTRACT BACKGROUND: Instability or tears of the long head of the biceps tendon (LHBT) may be present in more than 35% of rotator cuff repairs (RCR). OBJECTIVE: To compare clinical results from patients undergoing arthroscopic RCR, according to the procedure performed at the LHBT. DESIGN AND SETTING: Retrospective cohort study designed at the shoulder and elbow clinic of Instituto de Ortopedia e Traumatologia, Hospital das Clinicas, Faculdade de Medicina, Universidade de Sao Paulo, Brazil. METHODS: Functional results among patients were compared using the American Shoulder and Elbow Surgeons (ASES) and University of California Los Angeles (UCLA) scales, according to the LHBT approach adopted: no procedure, tenotomy or tenodesis. RESULTS: We evaluated 306 shoulders (289 patients): 133 underwent no procedure at the LHBT, 77 tenotomy and 96 tenodesis. The ASES scale at 24 months showed no difference (P = 0.566) between the groups without LHBT procedure (median 90.0; interquartile range, IQR 29), tenotomy (median 90.0; IQR 32.1) or tenodesis (median 94.4; IQR 22.7); nor did the UCLA scale (median 33; IQR 7 versus median 31; IQR 8 versus median 33; IQR 5, respectively, P = 0.054). The groups differed in the preoperative functional assessment according to the ASES and UCLA scale, such that the tenodesis group started from higher values. However, there was no difference in pre and postoperative scores between the groups. CONCLUSION: Tenodesis or tenotomy of the LHBT, in the sample analyzed, did not influence the clinical results from RCR, as assessed using the ASES and UCLA scales.

OBJETIVO:Comparar el promedio de curva de presión de contacto y el porcentaje de presión de contacto residual final en la interfase tendón-huella de una reparación transósea (TO) realizada con nudos cruzados y una configuración Mason-Allen modificada (MAM). MÉTODOS: Se utilizaron ocho hombros de cordero para simular una rotura de manguito rotador. Se midió la presión con un sensor digital. Se registró la presión basal durante la aplicación de carga cíclica y al final de la intervención. Se compararon dos reparaciones: dos túneles TOs con nudos cruzados (TOCs) (n » 4) y dos puntos MAMs (n » 4) utilizando suturas MaxBraid #2 (Zimmer Biomet, Warsaw, IN, EEUU). Se realizaron 1.000 ciclos, con una frecuencia de 2 Hz y una carga de 30 N. Se utilizó el test de t de Student, y se consideraron significativos valores de p < 0,05. RESULTADOS: El promedio de curva de presión de contacto en las piezas que fueron reparadas con suturas TOCs fue de 86,01 8,43%, mientras que con MAM fue de 73,28 12,01% (p < 0,0004). El promedio del porcentaje residual al final del ciclado fue de 71,57% para suturas TOCs y de 51,19% para MAM (p < 0,05). CONCLUSION: La reparación TOC presenta mayor promedio de curva de presión de contacto y mayor porcentaje de presión de contacto residual final en la interfase tendón-huella que la reparación con sutura MAM luego de carga cíclica estandarizada, lo que podría traducirse en una mejor cicatrización del tendón. NIVEL DE EVIDENCIA: Estudio de ciencia básica.

OBJECTIVE: To compare the average contact pressure curve and the percentage of final residual contact pressure at the tendon-footprint interphase of a transosseous (TO) repair performed with crossover sutures or a modified Mason-Allen (MMA) configuration. METHODS: Eight lamb shoulders were used to simulate a rotator cuff tear. The pressure was measured with a digital sensor. The baseline pressure was recorded during the application of the cyclic load and at the end of the intervention. Two repairs were compared: 2 crossover TO (CTO) sutures (n » 4) and 2 MMA sutures MMA (n » 4), using MaxBraid #2 (Zimmer Biomet, Warsaw, IN, US) sutures. A thousand cycles were performed, with a frequency of 2 Hz and a 30-N load. The Student t-test was used, and significance was set at p < 0.05. RESULTS: The average contact pressure curve was of 86.01 8.43% for parts repaired with CTO sutures, and of 73.28 12.01% for those repaired with MMA sutures (p < 0.0004). The mean residual percentage at the end of cycling was of 71.57% for CTO sutures, and of 51.19% for MMA sutures (p < 0.05). CONCLUSION: The CTO repair shows a higher average contact pressure curve and a higher percentage of final residual contact pressure at the tendon-footprint interphase than the MMA suture repair after standardized cyclic loading, potentially resulting in improved tendon healing. LEVEL OF EVIDENCE: Basic Science Study.

OBJECTIVE@#To explore clinical effect of arthroscopic meniscus tear strapping suture by rotator cuff suture threader.@*METHODS@#Forty patients with meniscus tear injury admitted from July 2015 to May 2019, including 27 males and 13 females, aged from 20 to 55 years old with an average of (36.0±1.4) years old. Menisci laceration was sutured with rotator cuff suture thread under arthroscopy. Postoperative complication was observed, Lysholm knee joint score before and after operation at 12 months were used to evaluate clinical effects, visual analogue scale (VAS) and range of knee flexion and extension were applied to evaluate recovery of pain and function.@*RESULTS@#All patients were followed up from 12 to 15 months with an average of (12.6±0.7) months.No complication such as joint effusion, suture failure occurred. Two patients occurred mild pain after activity without clinical physical abnormality, and 1 patient manifested moderate pain with joint space tenderness, the other rest without abnormal. Lysholm knee joint score was increased from (49.55±1.21) preoperatively to (98.95±0.42) at 12 months after operation, VAS score decreased from (5.18±0.78)preoperatively to (1.03±0.77) at 12 months after operation, and range of knee joint flexion and extension activity increased from (50.63±9.20)°preoperatively to (130.38±4.99)°after operation, and there were statistical differences in Lysholm knee joint score, VAS and range of knee joint flexion and extension activity (@*CONCLUSION@#Arthroscopic strapping suture by rotator cuff suture threading device applies to most meniscus injuries, including medial meniscus posterior horn tears, lateral meniscus body tears and lateral meniscus posterior horn tears. This technique meets the need of full-internal meniscus suture without specialmeniscus suture, and has advantages of convenient operation, less complications and good postoperative function.

Shoulder arthroscopic as a conventional method usually is applied to repair rotator cuff tears. In clinical, plenty single-row, double-row and transosseous tunnels suture technique are performed, but the ideal suture technique for rotator cuff repair is not found. Compared with single-row, double-row has better strength in biomechanics property. As the two best suture technique among the single-row, massive cuff stitch and modified Mason-Allen suture have the strongest biomechanics property. Clinical trials indicate that double-row could improve healing rates, but there are no significant difference in clinical outcome functional scores. Transosseous tunnel techniques possess a better bio-mechanic property, which could improve regional micro-environment and induce tendon-bone healing. Transosseous tunnel techniques are better for small to media size rotator cuff tears and osteoporosis patient. The author suggest that optimal rotator cuff repair technique should performed according to skill of performer and individual of patient by analysing bio-mechanic properties, clinical outcome, operative complexity and patient situation. The technique should follow simple opertaion, rapid, less trauma, stable fixation and utility to perform.

Introducción: El objetivo de este trabajo es evaluar resultados clínicos y funcionales de pacientes con una rotura irreparable del manguito rotador posterosuperior, sometidos a una transferencia artroscópica del trapecio inferior. Materiales y métodos: estudio de una cohorte retrospectiva de pacientes con roturas irreparables del manguito rotador, en quienes se realizó una transferencia del trapecio inferior asistida por artroscopía. Se evaluó la evolución clínica mediante la ganancia del rango de movilidad del hombro y la disminución del dolor. Del mismo modo, se evaluó la evolución funcional usando el índice de Constant-Murley y la valoración subjetiva del hombro (SSV, por sus siglas en inglés). Resultados: se incluyeron ocho pacientes, con un seguimiento promedio de veintidós meses. Obtuvimos una ganancia estadísticamente significativa de rotación externa de 32°, disminución de 5 puntos en la escala del dolor, aumento de 31 puntos en el score de Constant y un aumento de 38% del SSV. Se registró un aumento de 12° de elevación, sin embargo, este no fue estadísticamente significativo. Dos pacientes presentaron un seroma en el sitio de la cosecha del trapecio, que se resolvió con manejo conservador. Conclusión: la transferencia del trapecio inferior con asistencia artroscópica, en pacientes con rotura irreparable del manguito rotador posterosuperior, es una técnica segura que mejora significativamente la rotación externa y los índices funcionales en este grupo de pacientes. Tipo de estudio: Serie de casos IV

Introduction: The purpose of this study is to compare clinical and functional outcomes of patients with irreparable posterosuperior rotator cuff tears treated by arthroscopic assisted lower trapezius transfer. Materials and methods: retrospective cohort design of patients with irreparable rotator cuff tear, treated by arthroscopy-assisted lower trapezius transfer. The clinical evolution was evaluated according to the gain in the range of shoulder movement and the decrease of pain. Functional outcomes were evaluated using the Constant-Murley score and the subjective shoulder value (SSV). Results: eight patients were included, with average follow-up of twenty-two months. We obtained a statistically significant gain in active external rotation of 32°, 5-point decrease in the pain scale (VAS), a 31-point increase in the Constant score, and a 38% increase in SSV. There was a 12° increase in active forward elevation, however this was not statistically significant. Two patients had a seroma at the trapezius harvest site, which resolved with conservative treatment. Conclusion: arthroscopically assisted lower trapezius transfer in patients with irreparable posterosuperior rotator cuff tears were a safe technique that significantly improves external rotation and functional scores in patients. Type of study: Case series IV

OBJECTIVE@#To compare and analyze the mechanical differences between single-row suture anchor fixation for repairing rotator cuff injuries and double-row suture bridges for repairing rotator cuff injuries from a biomechanical perspective.@*METHODS@#The CT scan data of healthy adult shoulder joint were imported into Mimics, Geomagics and Hypermesh to carry out reverse reconstruction of two repair models, material assignment and mesh division, and the tearing of supraspinatus muscle was designed. After treatments, the load and boundary conditions were applied to the shoulder joint in ABAQUS software. The shoulder joint was fixed with four working conditions including flexion 15 °, flexion 30 °, internal rotation 15 ° and internal rotation 30 ° after anchor fixationand repair. The stress changes of the upper rotator cuff muscle and the anchor with thread were compared under these four conditions.@*RESULTS@#Under the two flexion conditions, the stress of the supraspinatus in the double row suture bridge fixation model was 8.3% and 12% less than that in the single-row suture anchor fixation, respectively. Under the two internal rotation conditions, the stress of supraspinatus in the double row suture bridge fixation model was 47% and 48% less than that in the single row fixation repair model, respectively.@*CONCLUSION@#The "load sharing" effect between the two rows of four anchors makes the stress distribution more dispersed, increases the contact area between the supraspinatus muscle and the humerus, reduces the stress of the anchor, avoids the serious stress concentration phenomenon, and explains the advantages of the fixation method of the double row suture bridge from the biomechanical angle.

OBJECTIVE@#To observe and compare the clinical outcomes between arthroscopic modified Mason-Allen repair and suture-bridge repair for medium-size rotator cuff tears.@*METHODS@#From January 2017 to January 2018, 22 patients with medium-size rotator cuff tears underwent arthroscopic modified Mason-Allen repair. There were 9 males and 13 females with an average age of (57.14±10.26) years. From February 2018 to January 2019, 20 patients with medium-size rotator cuff tears underwent arthroscopic suture-bridge repair. There were 6 males and 14 females with an average age of (57.75±7.57) years. The preoperative and postoperative clinical function was assessed by American Shoulder and Elbow Surgeons (ASES) and Constant score system. The healing status of repaired rotator cuff was assessed using MRI.@*RESULTS@#All patients were followed up, and the duration ranged from 24 to 33 months, with a mean of (26.38±2.29) months. In modified Mason-Allen group, AS###ES score and Constant score increased from (45.22±7.58) and (58.72±9.26) preoperatively to (96.89±3.49) and (93.18± 3.20) postoperatively. In suture-bridge group, ASES score and Constant score increased from(47.33±7.50) and (60.05±11.76) scores to (97.58±3.43) and (93.85±3.15). There were no significant differences in ASES score and Constant score between the two groups before and after operation. There were no significant differences in rotator cuff healing between the two groups.@*CONCLUSION@#Both arthroscopic modified Mason-Allen and suture-bridge repair for treatment of medium-size rotator cuff tears could obtain good clinical outcomes, and there were no significant differences in clinical outcomes between the two techniques.

RESUMEN Introducción: Diferentes estudios relacionan el diagnóstico del ultrasonido de alta resolución con el diagnóstico artroscópico del manguito rotador, ambos métodos son favorables y muestran una alta sensibilidad y especificidad al compararlos. Objetivo: Establecer la eficacia diagnóstica entre los hallazgos ecográficos de alta resolución y el diagnóstico artroscópico de rupturas parciales y completas del manguito rotador. Métodos: Se realizó un estudio analítico transversal con el objetivo de evaluar la eficacia diagnóstica del ultrasonido de alta resolución en pacientes del Hospital Provincial General Docente Dr. Antonio Luaces Iraola, de Ciego de Ávila, con diagnóstico clínico de rupturas parciales y completas del manguito rotador, de enero del 2016 a enero del 2019. El universo estuvo constituido por 62 pacientes con diagnóstico clínico de ruptura del manguito rotador que presentaban indicaciones quirúrgicas, a los que se les indicó un estudio imagenológico con ultrasonido de alta resolución y, con posterioridad, se les realizó la intervención quirúrgica por artroscopia, que fue tomada como criterio de verdad. Resultados: Predominó el sexo masculino, con una edad media menor que los del sexo femenino. Los hallazgos diagnósticos por ambos métodos mostraron concordancia en más de dos tercios de los pacientes que presentaron rupturas parciales y completas del espesor del manguito rotador. La ultrasonografía según el método empleado resultó un medio diagnóstico eficaz para las rupturas parciales y completas del espesor del manguito rotador. Conclusiones: El ultrasonido de alta resolución presentó una adecuada correlación en el diagnóstico de lesiones parciales o completas del manguito rotador, confirmada por artroscopia y es considerado un medio diagnóstico eficaz(AU)

ABSTRACT Introduction: Different studies relate the diagnosis of high-resolution ultrasound with the arthroscopic diagnosis of the rotator cuff. Both methods are favorable and show high sensitivity and specificity when they are compared. Objective: To establish diagnostic efficacy between the findings of high-resolution ultrasound and the arthroscopic diagnosis of partial and complete ruptures of the rotator cuff. Methods: A cross-sectional analytical study was carried out, aimed at evaluating the diagnostic efficacy of high-resolution ultrasound in patients of Dr. Antonio Luaces Iraola Provincial General Teaching Hospital, in Ciego de Ávila, with a clinical diagnosis of partial and complete ruptures of the rotator cuff, from January 2016 to January 2019. The universe consisted of 62 patients with a clinical diagnosis of rotator cuff rupture who presented surgical indications, and who were also indicated for an imaging study with high-resolution ultrasound and, subsequently, performed arthroscopic surgery, taken as a criterion of truth. Results: The male sex predominated, with an average age lower than those corresponding to female sex. The diagnostic findings by both methods showed agreement in more than two thirds of the patients who presented partial and complete ruptures of the rotator cuff's thickness. Ultrasonography, according to the method used, was an effective diagnostic tool for partial and complete ruptures of the rotator cuff's thickness. Conclusions: High-resolution ultrasound showed an adequate correlation in the diagnosis of partial or complete ruptures of rotator cuff, as confirmed by arthroscopy. It is considered an effective diagnostic means(AU)

ABSTRACT BACKGROUND: The accuracy of magnetic resonance imaging (MRI) for making the diagnosis of subscapularis tears presents wide variation in the literature and there are few prospective studies. OBJECTIVE: To compare the findings from MRI and arthroscopy for diagnosing subscapularis tears. DESIGN AND SETTING: Diagnostic test study performed in a tertiary care hospital. METHODS: We included patients who underwent arthroscopic rotator cuff repair and who had firstly undergone high magnetic field MRI without contrast. The images were independently evaluated by a shoulder surgeon and two musculoskeletal radiologists. Sensitivity, specificity, positive and negative predictive values, accuracy and inter and intra-observer agreement were calculated. RESULTS: MRIs on 200 shoulders were evaluated. The incidence of subscapularis tears was 69.5% (41.5% partial and 28.0% full-thickness). The inter and intra-observer agreement was moderate for detection of subscapularis tears. The shoulder surgeon presented sensitivity of 51.1% to 59.0% and specificity of 91.7% to 94.4%. The radiologists showed sensitivity of 83.5% to 87.1% and specificity of 41% to 45.9%. Accuracy ranged from 60.5% to 73.0%. CONCLUSION: The 1.5-T MRIs without contrast showed mean sensitivity of 70.2% and mean specificity of 61.9% for detection of subscapularis tears. Sensitivity was higher for the musculoskeletal radiologists, while specificity was higher for the shoulder surgeon. The mean accuracy was 67.6%, i.e. lower than that of rotator cuff tears overall.

Resumen: Introducción: La lesión masiva e irreparable del manguito rotador es un problema clínico que genera la pérdida de la función biomecánica del hombro. Esta lesión amerita una intervención oportuna, de modo tal que, previo a la artrosis, ayude a preservar la función articular durante el mayor tiempo posible. La opción de reparación de la cápsula superior con autoinjerto de fascia lata en la ruptura masiva e irreparable del manguito rotador es una técnica propuesta por Mihata, la cual ha demostrado obtener constantes mejorías de la función a corto y mediano plazo. Reporte de caso: Se trata de una mujer de 51 años con lesión irreparable del supraespinoso e infraespinoso y fallo en el tratamiento conservador. Clínicamente, se presentó con dolor de hombro intolerable y disfunción subjetiva; sin datos de artropatía moderada a severa, defectos óseos, rigidez o disfunción del deltoides, del dorsal ancho y del pectoral mayor. Se realizó reconstrucción de la cápsula superior con autoinjerto de fascia lata en Agosto de 2018 y seguimiento en las primeras 12 semanas. El resultado de este procedimiento mostró mejoría de las escalas SST de 58.33 y QD de 20.45 puntos con respecto a la valoración prequirúrgica (SST de 33.3 y QD de 27.7 puntos) y una movilización activa completa en abducción, flexión, extensión y rotación interna; el único arco de movilidad que no presentó mejoría fue la rotación externa del hombro, la cual se mantuvo en las mismas condiciones previas al procedimiento quirúrgico.

Abstract: Introduction: Massive and irreparable rotator cuff injury is a clinical problem that results in loss of shoulder function and merits timely intervention that helps preserve it as long as possible before arthropathy. The option of repair of the superior capsule with autograft of Fascia Lata in the massive and irreparable rupture of the rotator cuff, is a technique proposed by Mihata, which has demonstrated an improvement of function in the short and medium term. Case report: Female of 51 years old with irreparable tear of supraspinatus and infraspinatus, failure in conservative treatment, clinically with intolerable shoulder pain, subjective dysfunction without signs of moderate to severe arthropathy, no bone defects, stiffness or dysfunction of Deltoid, Latissimus Dorsi and Pectoralis Major. Superior capsule reconstruction was performed with autograft of fascia Lata in August 2018, with follow-up for the first 12 weeks. The result of this procedure showed improvement of the SST 58.33 and QD 20.45 scales compared to pre-surgical evaluation (SST 33.3 and QD 27.7). Full active mobilization in abduction, flexion, extension and internal rotation. The external rotation of the shoulder has no functional improvement.

Abstract: Introduction: The rotator cuff tears are a very frequent condition. The rotator cuff repair is a procedure often perform by the orthopedic surgeon. There are multiple techniques and suture configurations for this type of repairs. The double row configuration is one of the most used and consider very effective for mid-size and large size rotator cuff tears. The parachute configuration for this repair is a novel technique that may be useful for mid-size and large size tears, for this repair two medial double row anchors are used and one knotless lateral anchor. Our porpoise was to compare biomechanical performance and footprint coverage of a conventional suture-bridge double-row rotator cuff repair configuration versus a double-row-parachute. Methods: This paper shows the biomechanical behavior on a cadaver model of the parachute configuration, and also compares this conformation with a double row in a suture-bridge fashion. Our hipothesis was that the Parachute configuration's biomechanical performance is equivalent to the suture-bridging double-row technique. Results: The parachute configuration advantages show the advantage of using less anchors, which will decrease the surgical time and also the risks of using multiple hardware in the humeral head.

Resumen: Introducción: La lesión del manguito rotador es una patología común cuya reparación es un procedimiento realizado por los cirujanos ortopedistas. Existen muchas técnicas de reparación, así como múltiples configuraciones de anclas y suturas para realizar estos procedimientos. La técnica de doble fila es una de las más usadas para rupturas de tamaño mediano y grande con buenos resultados. La configuración en «paracaídas¼ para la reparación del manguito rotador puede llegar a ser útil para éstas, en este tipo de configuración se utilizan dos anclas mediales y un ancla sin nudos lateral. Nuestro objetivo fue la comparación de la eficiencia biomecánica y cobertura de la huella de una configuración convencional de doble fila «suture bridge¼ frente a una configuración en «paracaídas¼. Métodos: Este trabajo revisó el comportamiento biomecánico, en piezas cadavéricas, de la configuración de paracaídas y se comparó con la configuración de doble fila tipo «suture-bridge¼. Nuestra hipótesis era que el rendimiento biomecánico de la configuración de Parachute es equivalente a la técnica de doble fila «suture bridge¼. Resultados: Las posibles ventajas de la configuración de paracaídas son el uso de menos anclas, disminuyendo el tiempo quirúrgico y los riesgos de tener múltiples implantes en la cabeza humeral.

Resumen: Antecedentes: El aumento de la esperanza de vida de la población incrementa el número de pacientes con patología sintomática del manguito rotador. Nuestro objetivo fue determinar los resultados clínicos de una cohorte de pacientes mayores de 60 años con rotura del manguito rotador intervenidos mediante cirugía artroscópica de hombro (CAH). La hipótesis de trabajo fue que la CAH permitiría resultados clínicos satisfactorios. Material y métodos: De nuestra base de datos prospectiva de CAH seleccionamos los pacientes con: edad mayor de 60 años, rotura de manguito rotador, seguimiento mínimo de dos años. La valoración clínica se determinó según el test de Constant y el cuestionario Quick-DASH de calidad de vida. Resultados: 42 pacientes con una edad media de 66.7 años (rango de 60 a 83). La rotura del supraespinoso se reparó con sutura en doble fila en 25 pacientes (59.5%) y en fila única en 17 pacientes (40.5%). Lesiones asociadas: lesión de la porción larga del bíceps en 31 pacientes (48.4%), del subescapular en 24 pacientes (37.5%) y lesión tipo SLAP en tres pacientes (7.1%). El seguimiento medio fue de 32.4 meses. La puntuación media en la escala de Constant pasó de 48.3 puntos en el preoperatorio a 87.2 puntos al final del seguimiento. El cuestionario DASH síntomas/discapacidad disminuyó de 52.5 de media a 11.0 al final del seguimiento. Discusión: El tratamiento artroscópico de las roturas de manguito rotador en mayores de 60 años permite obtener resultados satisfactorios en los cuestionarios de valoración funcional y calidad de vida a mediano plazo.

Abstract: Introduction: Increasing life expectancies in population increase the number of patients with rotator cuff tears. The purpose of this study was to evaluate clinical outcomes after arthroscopy rotator cuff repair in patients over 60 years old. We hypothesized that shoulder arthroscopy would allow significant improvements in clinical outcomes without serious complications. Material and methods: We screened from our shoulder arthroscopy database patients older than 60 years old, with rotator cuff tear, and minimun 2-year follow-up. The patients were evaluated using Constant scores for clinical outcomes and Quick-DASH score for quality of life. Results: In total, 42 patients were enrolled in the study with a mean age of 66.7 years old (range 60 to 83). A double-row repair was indicated in 25 patients (59.5%), and single-row repair in 17 patients (40.5%). As associated injuries we found proximal biceps pathology in 31 patients (48.4%), subscapularis tears in 24 patients (37.5%), and SLAP tears in 3 patients (7.1%). Mean follow-up was 32.4 months. Constant scores improved from 48.3 preoperatively to 87.2 at final follow-up. Quick-DASH decreased from 52.5 preoperatively to 11.0 at final follow-up. Discussion: Arthroscopy cuff repair in patients older than 60 years old provides satisfactory clinical outcomes without morbidity at medium follow-up.

OBJECTIVE@#To investigate the method and clinical effects of arthroscopic rotator cuff repair with footprint ending shift for massive rotator cuff tear.@*METHODS@#From March 2015 to April 2019, 27 patients with massive rotator cuff tear underwent arthroscopic repair, including 12 males and 15 females, ranging in age from 37 to 74 years old, with an average age of (56.1±8.9) years. According to the tension of rotator cuff, 5 patients were treated with double row suture bridge technique, and 22 patients were treated with single row technique, among which 7 patients underwent partial rotator cuff repair. Before and after operation, University of California Los Angeles(UCLA) score, American Shoulder and Elbow Surgeons (ASES) score and visual analogue scale (VAS) were used to evaluate shoulder joint function.@*RESULTS@#All the patients were followed up, and the duration ranged from 8 to 40 months, with an average of (18.0±5.9) months. The UCLA score increased from preoperative 8.67±0.78 to final follow-up 30.89±1.07(@*CONCLUSION@#Arthroscopic rotator cuff repair with footprint ending shift for massive rotator cuff tear has satisfactory results, and single-row can be chosen to completely or partial repair rotator cuff tear for most patients.

The rate of rotator cuff injury repair and retear is high in elderly patients due to the combination of different degrees of osteoporosis. To solve this problem, many surgeons try to reduce retear rate of rotator cuff injuries in these patients by increasing the initial fixation strength of anchors and changing local bone conditions. The rapid advances of tissue engineering have made it possible to use growth factors as an aid. However, repair of rotator cuff injury with osteoporosis is still a great challenge for clinical workers. How to better increase anchor fixation strength, improve micro-environment of tendon and bone healing, reduce the rotator cuff retear rate have become the research focus in recent years. The paper reviewed literatures on the relationshipbetween osteoporosis and rotator cuff injury, effect of osteoporosis in rotator cuff tendon healing, methods of reducing osteoporosis on rotator cuff tendon healing, in order to guide clinical treatment, improve operative effect and postoperative satisfaction.

Rotator cuff tears are common among the elderly, and studies on the outcomes after rotator cuff repair in the elderly are limited. We carried out this meta-analysis with systematic literature search, aiming to clarify the outcomes after rotator cuff repair in the elderly as assessed by the American Shoulder and Elbow Surgeons (ASES) shoulder score. We conducted a literature search through October 2019 in PubMed and EMBASE databases and performed meta-analysis to calculate the summary mean difference comparing the post- and pre-operation ASES scores under both fixed-effect and random-effect models. Among 4978 studies identified through literature search, four studies (two in the United States, one in France, and one in Republic of Korea) were eligible for the meta-analysis, including 282 patients who were aged over 70 years. These studies had low heterogeneity as measured by Cochran's Q test (p=0.88) and I2 statistic (0%). The ASES scores on average increased by 39.7 (95% confidence interval 28.3-51.1, p<0.001) after rotator cuff repair, in both fixed-effect and random-effect models. No substantial publication bias was indicated. Our findings suggest improved outcomes after rotator cuff repair in the elderly population as measured by the ASES score, and such improvements have been consistent in previous studies.

OBJECTIVES: We compared the analgesic efficacy of a continuous suprascapular nerve block (C-SSNB) and a single-shot interscalene brachial plexus block (S-ISNB) for postoperative pain management in patients undergoing arthroscopic rotator cuff repair. METHODS: A total of 118 patients undergoing arthroscopic rotator cuff repair were randomly allocated to the S-ISNB or C-SSNB groups. Postoperative pain was assessed using the visual analog scale (VAS) at 1, 2, 6, 12, and 24 h postoperatively. Supplemental analgesic use was recorded as total equianalgesic fentanyl consumption. RESULTS: The C-SSNB group showed significantly higher VAS scores at 0−1 h and 1−2 h after the surgery than the S-ISNB group (4.9±2.2 versus 2.3±2.2; p<0.0001 and 4.8±2.1 versus 2.4±2.3; p<0.0001, respectively). The C-SSNB group showed significantly lower VAS scores at 6−12 h after the surgery than the S-ISNB group (4.1±1.8 versus. 5.0±2.5; p=0.031). The C-SSNB group required significantly higher doses of total equianalgesic fentanyl in the post-anesthesia care unit than the S-ISNB group (53.66±44.95 versus 5.93±18.25; p<0.0001). Total equianalgesic fentanyl in the ward and total equianalgesic fentanyl throughout the hospital period were similar between the groups (145.99±152.60 versus 206.13±178.79; p=0.052 and 199.72±165.50 versus 212.15±180.09; p=0.697, respectively) CONCLUSION: C-SSNB was more effective than S-ISNB at 6−12 h after the surgery for postoperative analgesia after arthroscopic rotator cuff repair.

ABSTRACT BACKGROUND: Shoulder pain is considered to be the third largest cause of musculoskeletal functional alterations in individuals presenting pain during movement. OBJECTIVE: The purpose of this synthesis of evidence was to identify the clinical effectiveness of conservative and surgical treatments reported in Cochrane systematic reviews among individuals diagnosed with rotator cuff disease. DESIGNAND SETTING: Review of systematic reviews, conducted in the Federal University of São Paulo (Universidade Federal de São Paulo, UNIFESP). METHODS: This synthesis of evidence included systematic reviews that had been published in the Cochrane database. The inclusion criteria were that these systematic reviews should involve individuals aged ≥ 16 years with rotator cuff disease, comparing surgical procedures with or without associated nonsurgical procedures versus placebo, no treatment or other nonsurgical interventions. RESULTS: Thirty-one systematic reviews were included, involving comparisons between surgical procedures and conservative treatment; procedures either combined or not combined with drugs, versus other procedures; and procedures involving exercises, manual therapy and electrothermal or phototherapeutic resources. CONCLUSIONS: The findings suggest that strengthening exercises, with or without associated manual therapy techniques and other resources, were the interventions with greatest power of treatment over the medium and long terms, for individuals with shoulder pain. These had greater therapeutic power than surgical procedures, electrotherapy or photobiomodulation. Protocol registration number in the PROSPERO database: ID - CRD42018096578.

Abstract Purpose: To evaluate the effects of rotator cuff muscle regeneration in sheep and establish an experimental model for the use of autologous stem cells as a treatment option for tendon injuries. Methods: Infrared muscle tenotomies and Penrose drain implantation were performed on 12 shoulders of six clinically healthy adult sheep. After 60 days, the tendons were submitted to tissue repair, drainage removal, and divided into two groups according to the use of autologous stromal stem cells for treatment. Muscle regeneration was performed by biopsy on days 14 and 34 after repair. Results: The treatment group with cell therapy showed neovascularization and expressive regeneration. Complete regeneration of the muscle pattern did not occur in any sample although some muscle gain was obtained in the group 1 samples at 34 days after repair and introduction of stem cells. Fatty infiltration of these samples from group 1 at 34 days was less intense than that in samples from group 2 at 34 days after repair without the introduction of autologous precursor cells. Conclusion: The sheep proved to be a good experimental model to assist in the development of research on muscle regeneration and the autologous manipulation of stem cells as a therapeutic option.
