Abstract Objective The aim of this study is to analyze various rehabilitation protocol and determine which methods will yield a better outcome. Methods The database reports were searched within 1990 until 2020, using PubMed, Cochrane library database, Ovid, Medline, and the other several published trials. A statistical analysis was made from Review Manager and Trial Sequential Analysis (TSA). Result The mean of re-rupture rate is 3.3% (n= 8) in the combination protocol until 8% (n= 48) in CAM protocol. Meta-analyses found no significant difference between Kleinert vs CAM in re-rupture rate. Also no significant difference in Duran vs CAM in rerupture rate. In Trial Sequential Analysis (TSA), the z-curve does not cross both of the trial sequential boundaries, a further trial with larger sample will be required. The TSA of flexion contracture CAM vs Kleinert was indicated that CAM protocol may be superior than Kleinert to reduce the incidence of flexion contracture. For the range of mean flexion contracture 6.6% (n= 18) in CAM to 23.6% (n= 76) in Kleinert protocol. Conclusion Current meta-analysis proposed that the combination technique will result less re-rupture incidence and better functional outcome in flexor zone II injuries than other techniques. The CAM method also results less flexion contracture than others. However, a further meta-analyses with larger sample trials will be required to confirm this review's conclusion.

Resumo Objetivo O objetivo deste estudo é analisar vários protocolos de reabilitação e determinar quais métodos produzem um melhor resultado. Métodos Os relatórios dos bancos de dados foram pesquisados entre 1990 e 2020, usando PubMed, banco de dados da biblioteca Cochrane, Ovid, Medline e vários outros ensaios publicados. Uma análise estatística foi feita a partir do Review Manager e Trial Sequential Analysis (TSA). Resultado A taxa média de re-ruptura é de 3,3% (n = 8) no protocolo combinado, e até 8% (n = 48) no protocolo de Movimento Ativo Controlado (MAC). As metanálises não encontraram diferença significativa entre Kleinert vs MAC na taxa de re-ruptura. Também não há diferença significativa entre Duran e MAC na taxa de re-ruptura. Na Trial Sequential Analysis (TSA), a curva z não cruza ambos os limites sequenciais de ensaio, será necessário um ensaio adicional com amostra maior. A TSA de contratura em flexão MAC vs Kleinert indicou que o protocolo MAC pode ser superior ao Kleinert para reduzir a incidência de contratura em flexão. Para a faixa de contratura média em flexão de 6,6% (n = 18) no MAC a 23,6% (n = 76) no protocolo Kleinert. Conclusão A metanálise atual propôs que a técnica combinada resultará em menor incidência de re-ruptura e melhor resultado funcional em lesões da zona flexora II do que outras técnicas. O método MAC também resulta em menos contratura em flexão do que outros. No entanto, serão necessárias mais metanálises com estudos com amostras maiores para confirmar a conclusão desta revisão.

Abstract Acute distal biceps injuries clinically present with sudden pain and acute loss of flexion and supination strength. The main injury mechanism occurs during the eccentric load of the biceps. The hook test is the most significant examination test, presenting the highest sensibility and specificity for this lesion. Magnetic resonance imaging, the gold standard imaging test, can provide information regarding integrity and identify partial and/or complete tears. The surgical treatment uses an anterior or double approach and several reattachment techniques. Although there is no clinical evidence to recommend one fixation method over the other, biomechanical studies show that the cortical button resists better to failure. Although surgical treatment led to an 89% rate of return to work in 14 weeks, the recovery of high sports performance occurred in 1 year, with unsustainable outcomes.

Resumo As lesões agudas do tendão distal do bíceps se apresentam, clinicamente, com uma dor súbita associada a perda aguda de força de flexão e supinação. Seu principal mecanismo de lesão ocorre durante contração excêntrica do bíceps. O "Hook Test" é o principal teste semiológico, sendo o mais sensível e específico. A ressonância magnética, exame padrão ouro para o diagnóstico, pode fornecer informações sobre a integridade, identificando as lesões parciais e/ou completas. O tratamento cirúrgico pode ser realizado por duas vias principais: anterior e por dupla via porém as técnicas de reinserção tendínea são diversas não havendo evidência clínica que recomende um método de fixação em detrimento ao outro; embora o botão cortical apresente maior resistência a falha nos estudos biomecânicos. Com o tratamento cirúrgico o retorno as atividades laborais foi de 89% em 14 semanas (média) porém ao esporte de alto rendimento o prazo foi longo, média de 1 ano, e não duradouro.

OBJECTIVE@#To investigate the feasibility and effectiveness of absorbable anchor combined with Kirschner wire fixation in the reconstruction of extension function of old mallet finger.@*METHODS@#Between January 2020 and January 2022, 23 cases of old mallet fingers were treated. There were 17 males and 6 females with an average age of 42 years (range, 18-70 years). The cause of injury included sports impact injury in 12 cases, sprain in 9 cases, and previous cut injury in 2 cases. The affected finger included index finger in 4 cases, middle finger in 5 cases, ring finger in 9 cases, and little finger in 5 cases. There were 18 patients of tendinous mallet fingers (Doyle type Ⅰ), 5 patients were only small bone fragments avulsion (Wehbe type ⅠA). The time from injury to operation was 45-120 days, with an average of 67 days. The patients were treated with Kirschner wire to fix the distal interphalangeal joint in a mild back extension position after joint release. The insertion of extensor tendon was reconstructed and fixed with absorbable anchors. After 6 weeks, the Kirschner wire was removed, and the patients started joint flexion and extension training.@*RESULTS@#The postoperative follow-up ranged from 4 to 24 months (mean, 9 months). The wounds healed by first intention without complications such as skin necrosis, wound infection, and nail deformity. The distal interphalangeal joint was not stiff, the joint space was good, and there was no complication such as pain and osteoarthritis. At last follow-up, according to Crawford function evaluation standard, 12 cases were excellent, 9 cases were good, 2 cases were fair, and the good and excellent rate was 91.3%.@*CONCLUSION@#Absorbable anchor combined with Kirschner wire fixation can be used to reconstruct the extension function of old mallet finger, which has the advantages of simple operation and less complications.

Superior labrum anterior posterior (SLAP) injury is a major challenge for orthopedic surgeons, due to the poor healing ability of the injured labrum. Although arthroscopic surgery is the gold standard for the treatment of SLAP injury, there are still disputes about the adaptation of different surgical techniques, the choice of anchors during operation, knotted or knotless anchors, and fixation methods. The authors believe that arthroscopic repair of SLAP lesions is effective for young patients with intact glenoid labrum(<35 years old) or with extensive activity, where single and knotless anchor is preferred. For the older patients(≥35 years old) with degeneration and wear of glenoid labrum, biceps tenodesis is more preferable, and interference screw fixation technique is recommended. As for patients with failed SLAP repair, biceps tenodesis can achieve a high success rate as a revision surgery. By review of the relevant literature in recent years, this paper summarizes the adaptation of different surgical methods of arthroscopic treatment of SLAP injury, intraoperative anchoring techniques, fixation methods and other improved surgical techniques.

Calcific tendinitis is a pathology characterized by the deposits of periarticular hydroxyapatite. Its pathophysiology is not completely known. It is clinically characterized by important inflammatory changes with incapacitating pain. It most commonly affects the shoulder joint and it rarely affects the hand and wrist. Given the unusual nature of this localization, we present the clinical case of a woman who developed calcific tendinitis of the third metacarpophalangeal muscle. We present the clinical evolution of the case, the treatments carried out, and a review of the literature related to this unusual localization of calcific tendinitis.

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.

The surgical treatment of massive rotator cuff tears is a clinical challenge for orthopaedic surgeons. Moreover, tendon retraction, adhesions and fatty infiltration after rotator cuff tear will further increase the difficulty of surgical repair. Therefore, it has become a hotspot and difficulty to repair massive rotator cuff tears with a better way in current research. In recent years, with the continuous development of arthroscopic techniques, shoulder arthroscopic surgery has become the gold standard for the treatment of massive rotator cuff tears, but the adaptations, effects and combined application of different surgical methods are still controversial. The author believes that arthroscopic debridement of shoulder joint and acromioplasty or tuberoplasty could relieve shoulder pain in the short-term for elderly patients with lower functional requirements;long biceps tenotomy or tenodesis is effective for patients with biceps long head tendon injury; complete repair is still the first line treatment for massive rotator cuff tears, but partial repair is possible for massive rotator cuff tears that could not be completely repaired;patch augmentation technology could bring good results for young patients with high functional requirements;for patients with limited internal and external rotation of the shoulder joint and high functional requirements, tendon transfers surgery is recommended;superior capsular reconstruction is more advantageous for young patients with no obvious glenohumeral arthritis, better deltoid muscle strength and higher functional requirements. In addition, subacromial spacer implantation has become a current research hotspot due to its advantages of small trauma, low cost and relative safety, and its long-term effect still needs to be further confirmed.

OBJECTIVE@#To investigate the morphological, histological and ultrastructural changes of acute closed rupture of Achilles tendon, in order to clarify the pathological basis of the injury and to explore the significance.@*METHODS@#From January 2015 to January 2019, 35 patients with acute Achilles tendon rupture who underwent the minimally invasive Achilles tendon suture technique were retrospectively analyzed. Among these patients, 12 cases in acute open Achilles tendon rupture group included 10 males and 2 females, with an average age of (35.1±9.7) years old ranging from 19 to 50, and the time from injury to operation was 2 to 8 hours with an average of(5.6±1.8);23 cases in acute closed Achilles tendon rupture group included 21 males and 2 females, with an average age of (35.5±6.6) years old ranging from 18 to 50, and the time from injury to operation was 3 to 15 hours with an average of (7.5±3.1). The gross appearance and imaging findings of the broken end of Achilles tendon tissue in the two groups were compared by naked eye observation and foot and ankle MRI at 4 to 6 hours before operation. HE staining, scanning and fluoroscopic electron microscopy, immunohistochemistry(Sirius red staining) were performed on the intraoperative Achilles tendon tissue specimens at 1 to 2 days after operation, the collagen fiber degeneration and local fat infiltration, collagen fiber shape, cell morphology and function, and the distribution of typeⅠand type Ⅲ collagen fibers in Achilles tendon were compared between the two groups.@*RESULTS@#Compared with the acute open Achilles tendon rupture group, the acute closed Achilles tendon rupture group had poor elasticity, hard texture, moderate edema, irregular shape of Achilles tendon broken end, horsetail shape, and more calcification around the broken end. HE staining results:the collagen fibers in the Achilles tendon of the acute open Achilles tendon rupture group were arranged irregularly, with hyaline degeneration and fat infiltration;The results of electron microscopy showed that collagen arranged disorderly and fibroblasts atrophied in the acute closed Achilles tendon rupture group. Immunohistochemical(Sirius staining) results:the proportion of collagenⅠin the acute open Achilles tendon rupture group and the acute closed Achilles tendon rupture group was(91.12±4.34)% and(54.71±17.78)% respectively, and the proportion of collagen Ⅲ was (8.88±4.34)% and (45.29±17.78)% respectively. The content of collagenⅠin the acute closed Achilles tendon rupture group was lower than that in the acute open Achilles tendon rupture group, and the content of collagen Ⅲ in the acute closed Achilles tendon rupture group was higher than that in the acute open Achilles tendon rupture group(P<0.05).@*CONCLUSION@#The morphology, histology and ultrastructure of the acute closed ruptured Achilles tendon are significantly altered compared with the normal Achilles tendon. The original fine and orderly spatial structure cannot be maintained, part of collagen Ⅰ is replaced by collagen Ⅲ, and the toughness and strength of the tendon tissue decreased, which may be the feature of degeneration of the Achilles tendon and an important pathological basis for closed Achilles tendon rupture.

Objetivo: Evaluar los resultados de la tenodesis suprapectoral mediante un miniabordaje en una serie de pacientes con lesión SLAP y desgarros completos de la porción larga del bíceps, y compararlos con los valores prequirúrgicos. Materiales y Métodos: Se incluyeron pacientes adultos tratados con dicha técnica entre 2019 y 2020, y un seguimiento mínimo de un año. Se registraron las características demográficas, la indicación de cirugía, el retorno a las actividades consideradas habituales por el paciente y las complicaciones. Se utilizó el puntaje ASES para hombro, y se midió la movilidad activa del hombro afectado. Además, se le preguntó al paciente si retomó la actividad que consideraba habitual, con opciones "sí" o "no". Se consignó si los pacientes reconocían un evento traumático con el inicio de los síntomas y se registró el diagnóstico con el que se llegó a la cirugía. Resultados: Se evaluó a 8 pacientes (7 hombres), con una mediana de la edad de 42.5 años. El seguimiento fue de 17 meses (RIC 13.5-21.5). Seis (75%) tenían diagnóstico de lesión SLAP tipo II y dos (25%), de desgarro completo. Seis pacientes (75%) asociaron los síntomas con un evento traumático. Las medianas de los rangos de movilidad finales fueron: flexión 180° (RIC 170°-180°), rotación interna 65° (RIC 60°-75°) y rotación externa 70° (RIC 5°-87,5°). Conclusión: La tenodesis suprapectoral tras una tenotomía artroscópica para casos de lesión SLAP tipo II o de desgarros completos de la porción larga del bíceps resultó una técnica segura y con resultados funcionales. Nivel de Evidencia: IV

Objective: To evaluate and compare outcomes in a case series of SLAP injuries and complete tears of the long head of the biceps treated with suprapectoral tenodesis using a mini-open approach. materials and methods: Patients aged over 18, treated between 2019 and 2020, with a minimum 1-year follow-up were included. The demographic characteristics, indication for surgery, return to activities considered usual by the patient, and complications were recorded. The American Shoulder and Elbow Surgeons (ASES) score for the shoulder was used, and the active range of motion of the affected shoulder was measured. In addition, the patients were asked if they were able to return to their daily activities. We recorded the diagnosis that led the patients to surgery and whether they had undergone a traumatic event coinciding with the onset of symptoms. Results: 8 patients were evaluated, the median age was 42.5, and the follow-up was 17 months (IQR 13.5-21.5). Six patients (75.0%) had a type II SLAP injury, and two (25.0%) had a complete LHB tear. Six patients (75.0%) associated the symptoms with a traumatic event. The final range of motion of the shoulder (median) was: flexion 180° (IQR 170°-180°), internal rotation 65° (IQR 60°-75°), and external rotation 70° (IQR 65°-87.5°). Conclusion: Suprapectoral tenodesis with a prior arthroscopic tenotomy for SLAP II cases or in cases of complete tears of the long head of the biceps is a safe technique for achieving functional outcomes.

Introducción: Las lesiones en las manos causadas por amoladora son comunes y generalmente ocurren en adultos jóvenes. En países en desarrollo, el ámbito doméstico y el trabajo informal son los escenarios más frecuentes. El objetivo de este estudio fue describir factores asociados a las lesiones por amoladora, y cuantificar y clasificar las heridas, según la gravedad y la región anatómica de la mano involucrada. Materiales y Métodos: Se realizó un estudio epidemiológico, retrospectivo. Entre 2016 y 2020, estudiamos a los pacientes con heridas de mano causadas por amoladora. Se analizaron el nivel educativo, la experiencia con la herramienta, el material cortado, el uso de equipo de protección personal, la edad y el sexo. Para determinar el patrón de las lesiones se realizó un análisis clínico-anatómico y radiológico detallado e individualizado. La gravedad fue evaluada con el Hand Injury Severity Score. Resultados: Se evaluó a928 pacientes (920 hombres y 8 mujeres, edad promedio 42 años). Solo el 22,4% usaba equipo de protección personal en el momento del accidente. El 84,5% (776 casos) realizaba tareas inusuales para la que esta herramienta no fue diseñada. La mano más afectada fue la izquierda (62,06%). En 784 pacientes, las heridas involucraban los dedos, el patrón de asociación predominante fue entre el 2do y 3er dedo (54,44%). Las lesiones fueron leves (24,1%), moderadas (41,3%), graves (26%) y mayores (8,6%). Conclusiones: Las lesiones por amoladora pueden resultar devastadoras. Una actualización epidemiológica reforzaría la necesidad de desarrollar métodos preventivos con el fin de disminuir su alta incidencia. Nivel de Evidencia: IV

Introduction: Hand injuries caused by angle grinders are frequent and generally take place among young adults. In developing countries, the domestic and informal work environments are the most frequent places where this could happen. The present study is aimed at describing associated factors to these types of injuries. Lesions were quantified and classified according to the sever-ity and anatomic region of the hand involved. Methods: An epidemiologic, retrospective study was performed between 2016 and 2020. The patients' level of education, previous experience using the machine, use of personal protective equipment (PPE), sex, and age were analyzed. To determine the pattern of the injuries, a clinical-anatomical and a detailed and individualized radiological analysis were performed on each patient. The severity was measured using the "Hand Injury Severity Score" (HISS). Results: 928 patients were studied (920 men, 8 women, average age of 42 years [range 18-67]). Only 22.4% were wearing PPE at the time of the accident. 776 participants were performing tasks for which the tool was not intended (84.5%). The left hand was the most af-fected (60%). In 784 patients, the injuries involved their fingers (84.48%); the predominant pattern was the index and middle finger (55%). According to the HISS, 24.1% were minor injuries, 41.3% were moderate, 26% were serious, and 8.6% were severe. Con-clusions: Injuries caused by an angle grinder can be devastating. We believe that an epidemiological update is likely to increase the need to develop preventive methods to decrease its high incidence. Level of Evidence: IV

Las fracturas de fémur distal, especialmente las abiertas, se asocian con traumas de alta energía. Las lesiones asociadas al-rededor de la rodilla son frecuentes; sin embargo, la asociación con una lesión completa del tendón cuadricipital ha sido poco documentada. El diagnóstico temprano y un adecuado tratamiento de ambas lesiones son fundamentales para conseguir buenos resultados posoperatorios. Presentamos dos casos de fracturas intrarticulares de fémur distal expuestas asociadas con lesiones completas del tendón cuadricipital. La reparación de la lesión tendinosa asociada mediante túneles transóseos luego de la fijación de la fractura permite comenzar un protocolo de rehabilitación temprano, esencial para obtener buenos resultados funcionales.Palabras clave: Fractura; fémur distal; lesión; tendón cuadricipital; aparato extensor. Nivel de Evidencia: V

Fractures of the distal femur, especially open fractures, occur in association with high-energy trauma. The presence of associated injuries around the knee is common; however, the association with a complete quadricipital tendon injury has been poorly documented. Early diagnosis and adequate treatment of both injuries is essential to achieve good postoperative outcomes. We present two cases of exposed intra-articular distal femoral fractures associated with complete quadricipital tendon injuries. The repair of the associated tendon injury with transosseous tunnels after fracture fixation allows an early rehabilitation protocol, essential to obtain good functional outcomes.Key words:Fracture; distal femur; injury; quadricipital tendon; extensor mechanism.

OBJETIVO: Comparar la presión y el área de contacto en la interfase tendón-huella de una reparación realizada con suturas transóseas simples y cruzadas. MÉTODOS: Se utilizaron doce hombros de cordero para simular una rotura de manguito rotador. Se midió el área de contacto en la interfase tendón-huella con láminas sensibles a presión; luego, 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 2 reparaciones: 2 túneles transóseos con nudos simples (TOS; n = 6) y 2 túneles transóseos con nudos cruzados (TOC; n = 6), utilizando FiberWire #2. Se realizaron 1.400 ciclos, con una frecuencia 2,5 Hz y una carga de 5 N. Se utilizó la prueba de Mann-Whitney, y ae consideraron significativos valores de p < 0,05. RESULTADOS: La reparación TOS presentó un 50,9 ± 12,7% distribución de presiones en comparación con 72,2 ± 5,3% en la reparación TOC (p < 0,009). La presión promedio en la reparación TOS fue 0,7 ± 0,1 MPa en comparación con 1,1 ± 0,2 MPa en la reparación TOC (p < 0,007). La reparación TOS registró una presión basal de 5,3 ± 5,3 N, presión final de 3,8 ± 4,6 N, y una variación de 51,7 ± 38%. La reparación TOC registró una presión basal de 10,7 ± 1,8 N, presión final de 12,9 ± 8,7 N, y una variación de 114,9 ± 65,9% (p < 0,044; p < 0,022; y p < 0,017, respectivamente). CONCLUSIÓN: La reparación TOC presenta mayor presión a nivel de la interfase tendón-hueso, menor pérdida de fuerza de contacto ante cargas cíclicas, y una mejor distribución de fuerza en la huella al comparar con la reparación TOS, lo que se podría traducir en mejor cicatrización tendínea.

OBJETIVE: To compare the pressure and contact area at the tendon-footprint interface of a repair performed with simple and crossed transosseous sutures. METHODS: Twelve lamb shoulders were used to simulate a rotator cuff tear. The contact area at the tendon-footprint interface was measured with pressure-sensitive films; then, the pressure was measured with a digital sensor. The baseline pressure was recorded during the application of a cyclic load and at the end of the intervention. A total of 2 repairs were compared: 2 transosseous sutures with single knots (STO; n = 6) and 2 transosseous sutures with crossed knots (TOC; n = 6) using FiberWire #2. In total, 1,400 cycles were performed, with a frequency of 2.5 Hz and a load of 5 N. The Mann-Whitney test was used. Values of p < 0.05 were considered significant.RESULTS: The TOS repair presented 50.9 ± 12.7% of pressure distribution compared to 72.2 ± 5.3% in the TOC repair (p < 0.009). The mean pressure in the TOS repair was of 0.7 ± 0.1 MPa compared to 1.1 ± 0.2 MPa in the TOC repair (p < 0.007). The TOS repair registered a basal pressure of 5.3 ± 5.3 N, a final pressure of 3.8 ± 4.6 N, and a variation of 51.7 ± 38%. The TOC repair registered a basal pressure of 10.7 ± 1.8 N, a final pressure of 12.9 ± 8.7 N, and a variation of 114.9 ± 65.9% (p < 0.044; p < 0.022; and p < 0.017 respectively).CONCLUSION: The TOC repair presents higher pressure at the tendon-bone interface, less loss of contact force under cyclic loads, and a better distribution of force on the footprint when compared with the TOS repair, which could translate into better tendon healing.

MÉTODOS La investigación se realizó de acuerdo con los métodos descritos en el Manual Cochrane. Los resultados se informan de acuerdo con el consenso de Ítems Preferidos de Reporte en Revisiones Sistemáticas y Metaanálisis (Preferred Reporting Items for Systematic Reviews and Meta-Analyses, PRISMA, en inglés). La búsqueda se realizó el 1er de junio de 2020. Se identificaron e incluyeron estudios ex vivo de ciencia básica y estudios biomecánicos publicados, que evaluaran la magnitud y distribución de la presión en la interfase tendón-huella de las roturas del manguito rotador reparadas entre enero de 2015 y junio de 2020. Se realizaron búsquedas sistemáticas en las bases de datos MEDLINE, Embase, Scopus y Google Scholar utilizando los términos y operadores booleanos: (Rotator Cuff OR Supraspinatus OR Infraspinatus OR Subscapularis OR Teres Minor) AND Pressure AND Footprint. En la base de datos Embase, respetando su sintaxis, se utilizó: Rotator Cuff AND Pressure AND Footprint. RESULTADOS Un total de 15 de los 87 artículos encontrados cumplieron con todos los criterios de elegibilidad y se incluyeron en el análisis. CONCLUSIÓN La presión y área de contacto sería optimizada biomecánicamente con una reparación transósea de doble fila equivalente, sin nudos en la hilera medial, y con el uso de cintas para su ejecución, conceptos de reparación específica para roturas delaminadas, y limitación de la abducción en el postoperatorio inmediato.

OBJETIVE To provide a comprehensive synopsis and analysis of biomechanical studies on the magnitude and distribution of pressure at the tendon-footprint interface of rotator cuff tears reported in the literature in the last five years. METHODS The research was performed according to the methods described in the Cochrane Manual. The results are reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) consensus. The search was performed on June 1st, 2020. We identified and included ex vivo basic science studies and published biomechanical studies that evaluated the magnitude and distribution of pressure at the tendon-footprint interface of rotator cuff tears repaired between January 2015 and June 2020. Systematic searches on the MEDLINE, Embase, Scopus and Google Scholar databases were performed using the terms and Boolean operators: (Rotator Cuff OR Supraspinatus OR Infraspinatus OR Subscapularis OR Teres Minor) AND Pressure AND Footprint. In the Embase database, respecting its syntax, the following was used: Rotator Cuff AND Pressure AND Footprint. RESULTS In total, 15 of the 87 articles found fulfilled all the eligibility criteria and were included in the analysis. CONCLUSION The pressure and contact area would be biomechanically optimized with an equivalent transosseous double-row repair, without knots in the medial row, and with the use of tapes for its execution, specific repair concepts for delaminated tears, and a limitation of abduction in the immediate postoperative period.
