Comparison between portals for placement of anchors in shoulder instability / Comparação entre portais para colocação de âncoras na instabilidade do ombro

ABSTRACT Objective: to radiographically compare the effects of anchor positioning in the arthroscopic treatment of shoulder instability, in the 3- and 5-o'clock portals. Methods: retrospective study of 36 patients, operated by two shoulder surgeons at the Unimed BH hospital, between January 2013 and January 2018. Each surgeon used only one of either the 3- or the 5-o'clock portal. After postoperative radiographs we performed angle comparisons between the greatest glenoidal axis, the angle of anchor insertion and distance from the inferior pole. Results: the 5-o'clock portal provided better placement than its 3-o'clock counterpart, which allowed for greater orthogonality in relation to the glenoid rim (p < 0.05). Conclusion: the 5-o'clock portal allowed for better anchor placement than the 3 o'clock one. Level of Evidence II, Clinical Trial.

RESUMO Objetivo: Comparar radiograficamente o posicionamento das âncoras utilizadas no tratamento artroscópico da instabilidade do ombro, através dos portais de 3 ou 5 horas. Métodos: Avaliação retrospectivae de 36 pacientes, operados por dois cirurgiões de ombro do Hospital Unimed BH, entre janeiro de 2013 e janeiro de 2018. Cada cirurgião utilizou apenas uma das técnicas - portal de 3 ou 5 horas. As radiografias pós-operatórias foram avaliadas e comparadas a angulações entre o maior eixo da glenoide, o ângulo de inserção da âncora e a distância em relação ao polo inferior. Resultados: A utilização do portal de 5 horas propiciou a colocação mais adequada das âncoras em relação ao portal de 3 horas, permitindo o posicionamento mais ortogonal em relação à borda da glenoide (p < 0,05). Conclusão: A utilização do portal de 5 horas apresenta melhor posicionamento das âncoras quando comparado ao portal de 3 horas. Nível de evidência II, Ensaio Clínico.

Retrospective analysis and comparison of total internal disability preservation technique and standardized reconstruction technique / 中国骨伤

OBJECTIVE@#To investigate the efficacy and clinical results of total internal protection technique in anterior cruciate ligament reconstruction.@*METHODS@#A total of 56 patients undergoing anterior cruciate ligament reconstruction treated from January 2018 to December 2019 were selected. According to the different surgical methods, they were divided into total internal reconstruction group and standard bone tunnel group. There were 21 patients in the total internal reconstruction group, including 15 males and 6 females, aged from 20 to 48 with an average of (35.6±6.7) years old, and 35 patients in the standard tibial tunnel group, including 26 males and 9 females, aged 22 to 51 years old with an average of (33.7±9.6) years old. Preoperative examination of Lachman test was positive, magnetic resonance indicated anterior cruciate ligament rupture. There were no significant differences between the two groups in age, sex, body mass index, time from injury to ACL reconstruction, combined meniscus injury and operation method, operation time, ligament diameter, ligament length and other general information. Postoperative evaluation included operation duration, length and diameter of transplanted tendon after braid. International Knee Documentation Committee (IKDC) score, Lysholm score, Tegner score and perioperative complications 2 years after surgery.@*RESULTS@#Both groups were followed up, ranging from 24 to 30 months with an average of (26.9±3.4) months. Postoperative incision healing was good, and no failure or joint infection occurred at the last follow-up. There was no statistically significant difference between the two groups in IKDC score, Lysholm score and Tegner score before, 1 year and 2 years after surgery. However, IKDC score, Lysholm score and Tegner score at 1 year and 2 years after surgery.@*CONCLUSION@#The same postoperative function and stability of knee joint can be obtained by both the residual whole technique and the standardized reconstruction technique. In the residual whole group, only the semitendinosus muscle is taken, and the femoral thin muscle is retained, with greater tibial bone mass preserved, which is safe and effective in clinical practice.

Short-term effectiveness of arthroscopic repair via modified subacromial viewing portal in treatment of Lafosse Ⅰ subscapularis tendon tears / 中国修复重建外科杂志

OBJECTIVE@#To investigate short-term effectiveness of arthroscopic repair via modified subacromial viewing portal (hereinafter referred to as modified viewing portal) in treatment of LafosseⅠsubscapularis tendon tears.@*METHODS@#A clinical data of 52 patients with LafosseⅠsubscapularis tendon tears, who underwent the arthroscopic repair via modified viewing portal between October 2020 and November 2022 and met the selective criteria, was retrospectively analyzed. There were 15 males and 37 females with an average age of 63.4 years (range, 41-76 years). Twelve patients had trauma history and the other 40 patients had no obvious inducement. The main clinical symptom was shoulder pain and the hug resistance tests were positive in all patients. The interval between symptom onset and admission ranged from 3 to 26 months (mean, 7.2 months). The shoulder pain and function were evaluated by visual analogue scale (VAS) score, American Shoulder and Elbow Surgeons (ASES) score, and University of California Los Angeles (UCLA) score before operation and at 12 months after operation. The shoulder range of motion (ROM) of forward flexion, abduction, and external rotation and the internal rotation strength were measured before operation and at 3 and 12 months after operation. MRI was performed at 3-6 months after operation to assess the tendon healing and the structural integrity and tension of reattached tendon. Patient's satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention, no complication such as incision infection or nerve injury occurred. All patients were followed up 12-37 months (mean, 18.5 months). The VAS, UCLA, and ASES scores at 12 months after operation significantly improved when compared with those before operation ( P<0.05). The ROMs of abduction and forward flexion and the internal rotation strength at 3 and 12 months significantly improved when compared with those before operation ( P<0.05); and the ROMs at 12 months significantly improved compared to that at 3 months ( P<0.05). However, there was no significant difference ( P>0.05) in the ROM of external rotation at 3 months compared to that before operation; but the ROM at 12 months significantly improved compared to that before operation and at 3 months after operation ( P<0.05). Thirty-one patients underwent MRI at 3-6 months, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing; 3 patients underwent tendon re-tear. At last follow-up, 41 patients (78.8%) were very satisfied with the effectiveness, 7 were satisfied (13.5%), and 4 were dissatisfied (7.7%).@*CONCLUSION@#Arthroscopic repair via modified viewing portal for Lafosse Ⅰsubscapularis tendon tears, which can achieve the satisfactory visualization and working space, can obtain good short-term effectiveness with low overall re-tear risk.

Abstract Objective To validate the low-cost model for arthroscopy training and analyze the acceptance and usefulness of the developed simulator in medical teaching and training. Method Ten medical students, ten third-year orthopedic residents, and ten shoulder surgeons performed predetermined tasks on a shoulder simulator twice. The parameters used were time to complete the tasks, number of looks at the hands, GOALS score (Global Operative Assessment of Laparoscopic Skills) and comparison between groups and within groups. An adapted Likert scale was applied addressing the individuals' impressions about the simulator and its applicability. Results In the intergroup comparison, the shoulder surgeons had better scores and times than the other groups. When the tasks were repeated, the group of surgeons had a 59% improvement in time (p < 0.05), as did the group of medical students. In the GOALS score, shoulder surgeons had consistently better scores than the other groups. And when we evaluated the evolution from the first to the second test, the group of surgeons and the group of academics had a statistically significant improvement (p < 0.05). In terms of lookdowns, there was a decrease in all groups. There was consensus that the simulator is useful in training. Conclusion The simulator developed allowed the differentiation between individuals with different levels of training in arthroscopic surgery. It was accepted by 100% of the participants as a useful tool in arthroscopic shoulder surgical training.

Bloqueo interescalénico en el contexto de la recuperación acelerada para artroscopía de hombro: serie de casos / Interscalene block in the context of enhanced recovery for shoulder: A case series

Introducción La aplicación de la recuperación acelerada en cirugía de hombro no ha tenido una aceptación tan favorable. Por ello, el objetivo de este estudio fue presentar y describir el uso de bloqueo interescalénico para favorecer la recuperación acelerada en una serie de pacientes sometidos a cirugía artroscopica de hombro. Métodos Se incluyeron 35 pacientes sometidos a cirugía artroscópica de hombro, en quienes se administró bloqueo interescalénico y sedación. Posteriormente se evaluó la intensidad del dolor, náuseas, vómito, disnea, presencia de síndrome de Horner, visión borrosa, ronquera, tiempo transcurrido hasta el alta, reingresos no planeados, satisfacción del paciente y cumplimiento de los criterios de alta hospitalaria en las primeras 12 horas siguiendo los criterios de una recuperación acelerada. Resultados En total, 27 pacientes (77,1%) tuvieron clasificación de la (ASA) I y 8 pacientes (22,9%) ASA II. Además, 97,1% fueron reparaciones de manguito rotador. Previo al alta, dos pacientes (5,7%) presentaron náuseas. Al momento del alta ningún paciente presentó disnea o visión borrosa, dos pacientes (5,7%) presentaron ronquera y la mediana de intensidad del dolor fue de 1,0 (0,0 a 7,0). Entre las 24 y 48 horas solo un (2,8%) paciente presentó náuseas y la mediana de intensidad del dolor fue de 1,0 (0,0 a 8,0). Todos los pacientes se mostraron satisfechos con disposición a repetir la experiencia. El 100% de pacientes cumplió los criterios médicos de alta a las 12 horas y 30 pacientes (85,7%) se dieron de alta el mismo día. La estancia fue de 12 (11,5 a 12,5) horas y ningún paciente reingresó. Conclusión En pacientes seleccionados, con un equipo quirúrgico-anestésico comprometido, capacitado y con experiencia, hay una alta posibilidad de que el bloqueo interescalénico favorezca la realización de programas de recuperación acelerada en cirugía artroscópica de hombro.

Introduction The application of enhanced recovery in shoulder surgery has not had such a favorable acceptance, therefore, the objective of this study was to present and describe the use of interscalene block to promote enhanced recovery in a series of patients undergoing shoulder arthroscopic surgery. Methods Thirty-five patients undergoing arthroscopic shoulder surgery were included, in whom interscalene blockade and sedation were administered. Subsequently, pain intensity, nausea, vomiting, dyspnea, presence of Horner's syndrome, blurred vision, hoarseness, time elapsed to discharge, unplanned readmissions, patient satisfaction, and compliance with hospital discharge criteria in the first 12 weeks were evaluated, hours following the criteria of an enhanced recovery. Results 27 patients (77,1%) had ASA I and 8 patients (22,8%) ASA II, 97,1% were rotator cuff repairs. Before discharge, two patients (5.7%) had nausea. At discharge, no patient had dyspnea or blurred vision, two patients (5.7%) developed hoarseness, and the median pain intensity was 1.0 (0.0-7.0). Between 24 and 48 hours only one patient (2.8%) presented nausea and the median pain intensity was 1.0 (0.0-8.0). All the patients were satisfied with their willingness to repeat the experience, 100% of the patients met the criteria for medical discharge after 12 hours, 30 patients (85.7%) were discharged the same day, the stay was 12 (11.5 to 12.5) hours, and no patient was readmitted. Conclusion In selected patients with a committed, trained and experienced surgical-anesthetic team, there is a high possibility that the interscalene block will favor the performance of enhanced recovery programs in shoulder arthroscopic surgery.

Evaluación en la aplicación de ácido hialurónico en pacientes postoperados de artroscopía con gonartrosis grado II-III mediante la escala de WOMAC / Evaluation of the application of hyaluronic acid in postoperative arthroscopy patients with grade II-III gonarthrosis using the WOMAC scale

Resumen: Introducción: la gonartrosis es una enfermedad degenerativa, cuya pérdida de cartílago origina cambios en el hueso adyacente y su respuesta produce deformaciones e intentos de regeneración. En 1934 Meyer y Palmer aislaron el humor vítreo bovino, polisacárido denominado ácido hialurónico, que tiene la propiedad de visco elasticidad. Hoy en día se conocen múltiples procedimientos realizados en ortopedia, con la finalidad de limitar el proceso degenerativo que este conlleva. Objetivo: conocer el uso y la eficacia del ácido hialurónico, en el paciente que requiere artroscopía de rodilla, valorando la evolución del paciente mediante escala de WOMAC; así como el tiempo ideal de aplicación del ácido hialurónico en este grupo de estudio. Material y métodos: ensayo clínico, no aleatorizado longitudinal, prospectivo, analítico. Se valoraron 48 pacientes de 45 a 60 años de edad, divididos en tres grupos con diagnóstico de gonartrosis grado II-III, en quienes se realizaron artroscopía con posterior aplicación ácido hialurónico; en el transquirúrgico (grupo 1), al mes del postquirúrgico (grupo 2) y sin aplicación (grupo 3) en un período de Septiembre de 2015 a Junio de 2016 en el Hospital del ISSSTE «Dr. Darío Fernández Fierro¼. Resultados: el tratamiento mostró diferencias en los pacientes en cuanto a reducción de dolor y rigidez; y mejoría en capacidad funcional. Conclusión: a pesar de que no es concluyente si algún tratamiento es mejor que otro, ciertos datos sugieren que el utilizar ácido hialurónico en el transquirúrgico mejora la rigidez y la función, sin embargo, no logró ser estadísticamente significativo.

Abstract: Introduction: gonarthrosis is a degenerative disease, whose loss of cartilage causes changes in the adjacent bone and its response produces deformations and attempts at regeneration. In 1934 Meyer and Palmer isolated bovine vitreous humor, a polysaccharide called hyaluronic acid, which has the property of visco-elasticity. Today, multiple procedures performed in orthopedics are known, in order to limit the degenerative process that this entails. Objective: to know the use and efficacy of hyaluronic acid in the patient requiring knee arthroscopy, evaluating the evolution of the patient using the WOMAC scale; as well as the ideal time of application of hyaluronic acid in this study group. Material and methods: clinical, non-randomized, prospective, analytical trial. 48 patients from 45 to 60 years of age, divided into 3 groups with a diagnosis of gonarthrosis grade II-III, who underwent arthroscopy with subsequent hyaluronic acid application, were evaluated; in the postoperative period (group 1), one month after the postoperative period (group 2) and without application (group 3) in a period from September 2015 to June 2016 at the ISSSTE Hospital «Dr. Darío Fernández Fierro¼. Results: the treatment showed differences in patients regarding reduction of pain and stiffness; and improvement in functional capacity. Conclusion: despite, there are no conclusive results if the treatment is better than the other, certain data suggests that using hyaluronic acid in the postoperative improves rigidity and function, however, it was not statistically significant.

Total arthroscopic reconstruction of the anterior cruciate ligament / Reconstrução artroscópica total do ligamento cruzado anterior / Reconstrucción artroscópica total del ligamento cruzado anterior

ABSTRACT Introduction: Total internal arthroscopic anterior cruciate ligament reconstruction is one of the new technologies in recent years. The main advantage is the need for only one tendon for the surgical procedure. Objective: Compare the clinical effects of total internal and traditional anterior cruciate ligament reconstruction techniques. Methods: From January 2019 to January 2022, the clinical data of 45 patients with anterior cruciate ligament reconstruction were retrospectively analyzed, including 32 males and 13 females aged 18-33 years, mean of 24.2 ± 3.3 years. Total internal reconstruction was performed in 22 cases (total internal group) and traditional reconstruction in 23 cases (traditional group). The two groups recorded and compared the time of injury, duration of surgical procedure, postoperative VAS score, and recovery of knee function. The International Knee Literature Committee (IKDC) and the Lysholm scoring system were used to evaluate clinical efficacy. Results: 45 patients were followed for 14 to 18 months, mean (15.4 ± 1.3) months. There were no significant differences between the two groups in time between operation and injury, duration of operation, IKDC, and Lysholm score of the affected knee at the last follow-up. However, there were significant differences in the VAS score on day one, day three, day seven, two weeks, and one month after the operation (P < 0.05), with no significant difference at three months, six months, and one year after the operation. Conclusion: The effect of total internal reconstruction of the anterior cruciate ligament is equivalent to that of traditional methods, with less postoperative pain, making it the ideal choice for this treatment.

Metodología: Realizamos una búsqueda bibliográfica online en los buscador PubMed y en la Biblioteca Virtual en Salud (BVS) utilizando los siguientes términos MESH: ("Arthritis, Infectious/surgery"(Mesh) OR "Arthritis, Infectious/therapy"(Mesh)), utilizando filtros de búsqueda y aplicando criterios de inclusión y exclusión según nuestro objetivo. De los artículos incluidos se obtuvieron entre otros los siguiente datos: país, año, nivel de evidencia, número de pacientes con artritis séptica, articulación afectada, edad media, seguimiento promedio, tipo de tratamiento quirúrgico realizado de inicio y sus resultados según cada autor : complicaciones (de la enfermedad y del procedimiento ) y/o secuelas (en base a evolución clínica y radiológica), necesidad de un tratamiento quirúrgico adicional ante la falla del método terapéutico inicial y además de conclusiones relevantes de cada autor. Resultados: Se incluyeron un total de 22 artículos: 8 para el lavado por artroscopia, 6 para el lavado por artrocentesis, 4 para el lavado por artrotomía, ademas de otros 4 artículos que realizaba un análisis comparativo: dos de ellos entre lavado artroscópico y lavado por artrotomía y los otros dos entre lavado por artrocentesis y lavado abierto. El lavado artroscópico se encuentra en lo más alto de nuestra revisión ya que presenta los mejores resultados con solo un 6% complicaciones y/o secuelas (en solo 4 de los 8 artículos incluidos), con un total de 13 pacientes (8,7% ) que requirieron un tratamiento adicional (5 artrotomías y 8 un nueva lavado artroscópico ) y se destacan ademas 3 artículos con un 100% de buenos resultados, en los que no se presentaron complicaciones y/o secuelas, ni se requirió un segundo lavado, mientras que solo en 3 trabajos, de los 8, se necesitó de la artrotomía adicional para la resolución final. Para el lavado por artrocentesis se obtuvo el menor porcentaje de complicaciones y/o secuelas con un 2%, (reportado en tres de los 6 trabajos), y solo el 9,7% necesitaron de un segundo método terapéutico diferente a la aspiración articular (23 artrotomías y 2 artroscopias), destacando ademas la repetición de la punción (hasta 4 veces) como dentro de la directiva terapéutica del autor en dos artículos, y que para éste método se encontró el mayor número de pacientes. El lavado por artrotomía como método inicial obtuvo los peores resultados, con un 12% de complicaciones y/o secuelas y un 22,6% de lavados adicionales. Conclusiones: A pesar de que el lavado abierto por artrotomía se toma como el ¨ gold-standard ¨, teniendo indicaciones absolutas en el tratamiento quirúrgico de la artritis séptica en niños (especialmente en cadera), de nuestro análisis se desprende que ésta opción arroja los peores porcentajes de resultados, duplicando el porcentaje de necesidad de lavado adicional y el de complicaciones, en comparación con el lavado artroscópico. Existen otros métodos terapéuticos que se presentan como procedimientos menos invasivos, seguros y eficaces, respaldados por buenos resultados en la biografiaría, como son: el lavado por artroscopia (que presentó el porcentaje más bajo de pacientes con necesidad de lavado adicional, con el mayor número de artículos con buenos resultados en general, con un porcentaje de complicaciones por debajo del lavado por artrotomía) y el lavado por artrocentesis (que presentó el porcentaje de compilaciones más bajo de las 3 opciones analizadas.

Introduction: Despite its low incidence, osteoarticular infections can generate devastating complications and sequelae for the developing child with his growing skeleton. The general management of the pathology must be multidisciplinary, associating antibiotic therapy and adequate surgical treatment if required. The objective of our work is to analyze the results on the different surgical therapeutic options (puncture-aspiration, arthroscopic lavage or open lavage) in the treatment of septic arthritis in the pediatric age, by carrying out a systematic review of the bibliography. Methodology: We conducted an online bibliographic search in the PubMed search engine and in the Virtual Health Library (VHL) using the following MESH terms: ("Arthritis, Infectious/surgery"(Mesh) OR "Arthritis, Infectious/therapy"(Mesh)), using search filters and applying inclusion and exclusion criteria according to our objective. The following data were obtained from the included articles, among others: country, year, level of evidence, number of patients with septic arthritis, affected joint, mean age, average follow-up, type of initial surgical treatment and its results according to each author: complications (of the disease and of the procedure) and/or sequelae (based on clinical and radiological evolution), the need for additional surgical treatment in the event of failure of the initial therapeutic method, and in addition to relevant conclusions of each author. Results: A total of 22 articles were included: 8 for arthroscopic lavage, 6 for arthrocentesis lavage, 4 for arthrotomy lavage, in addition to another 4 articles that performed a comparative analysis: two of them between arthroscopic lavage and lavage. by arthrotomy and the other two between lavage by arthrocentesis and open lavage. Arthroscopic lavage is at the top of our review as it presents the best results with only 6% complications and/or sequelae (in only 4 of the 8 articles included), with a total of 13 patients (8.7% ) that required additional treatment (5 arthrotomies and 8 a new arthroscopic lavage) and also highlight 3 articles with 100% good results, in which there were no complications and/or sequelae, nor did a second lavage be required, while that only 3 of the 8 studies required an additional arthrotomy for the final resolution. For lavage by arthrocentesis, the lowest percentage of complications and/or sequelae was obtained with 2% (reported in three of the 6 works), and only 9.7% required a second therapeutic method other than joint aspiration (23 arthrotomies and 2 arthroscopies), also highlighting the repetition of the puncture (up to 4 times) as within the author's therapeutic directive in two articles, and that the largest number of patients was found for this method. Arthrotomy lavage as the initial method obtained the worst results, with 12% complications and/or sequelae and 22.6% additional lavages. Conclusions: Even though open lavage by arthrotomy is taken as the ¨ gold-standard ¨, having absolute indications in the surgical treatment of septic arthritis in children (especially in the hip), from our analysis it can be deduced that this option yields the worse percentages of results, doubling the percentage of need for additional lavage and the percentage of complications, compared to arthroscopic lavage. There are other therapeutic methods that are presented as less invasive, safe and effective procedures, supported by good results in the biography, such as: arthroscopic lavage (which presented the lowest percentage of patients requiring additional lavage, with the highest number of articles with good results in general, with a percentage of complications below lavage by arthrotomy) and lavage by arthrocentesis (which presented the lowest percentage of compilations of the 3 options analyzed).

Introdução: Apesar de sua baixa incidência, as infecções osteoarticulares podem gerar complicações e sequelas devastadoras para a criança em desenvolvimento com seu esqueleto em crescimento. O manejo geral da patologia deve ser multidisciplinar, associando antibioticoterapia e tratamento cirúrgico adequado, se necessário. O objetivo do nosso trabalho é analisar os resultados das diferentes opções terapêuticas cirúrgicas (punção-aspiração, lavagem artroscópica ou lavagem aberta) no tratamento da artrite séptica em idade pediátrica, através da realização de uma revisão sistemática da bibliografia. Metodologia: Foi realizada uma busca bibliográfica online no buscador PubMed e na Biblioteca Virtual em Saúde (BVS) utilizando os seguintes termos MESH: ( "Arthritis, Infectious/surgery"(Mesh) OR "Arthritis, Infectious/therapy"(Mesh) ), utilizando filtros de busca e aplicando critérios de inclusão e exclusão de acordo com nosso objetivo. Os seguintes dados foram obtidos dos artigos incluídos, entre outros: país, ano, nível de evidência, número de pacientes com artrite séptica, articulação afetada, idade média, seguimento médio, tipo de tratamento cirúrgico inicial e seus resultados de acordo com cada autor: complicações (da doença e do procedimento) e/ou sequelas (com base na evolução clínica e radiológica), necessidade de tratamento cirúrgico adicional em caso de falha do método terapêutico inicial e, além das conclusões relevantes de cada autor. Resultados: Foram incluídos 22 artigos: 8 para lavagem artroscópica, 6 para lavagem artrocentese, 4 para lavagem artrotômica, além de outros 4 artigos que realizaram uma análise comparativa: dois deles entre lavagem artroscópica e lavagem por artrotomia e a outros dois entre lavagem por artrocentese e lavagem aberta. A lavagem artroscópica está no topo da nossa revisão por apresentar os melhores resultados com apenas 6% de complicações e/ou sequelas (em apenas 4 dos 8 artigos incluídos), com um total de 13 doentes (8,7%) que necessitaram de tratamento adicional (5 artrotomias e 8 uma nova lavagem artroscópica) e também destacam 3 artigos com 100% de bons resultados, nos quais não houve complicações e/ou sequelas, nem foi necessária uma segunda lavagem, enquanto que apenas 3 dos 8 estudos necessitaram de uma artrotomia para a resolução final. Para a lavagem por artrocentese, o menor percentual de complicações e/ou sequelas foi obtido com 2% (relatado em três dos 6 trabalhos), e apenas 9,7% necessitaram de um segundo método terapêutico diferente da aspiração articular (23 artrotomias e 2 artroscopias), destacando também a repetição da punção (até 4 vezes) conforme diretriz terapêutica do autor em dois artigos, e que o maior número de pacientes foi encontrado para este método. A lavagem por artrotomia como método inicial obteve os piores resultados, com 12% de complicações e/ou sequelas e 22,6% de lavagens adicionais. Conclusões: Apesar de a lavagem aberta por artrotomia ser tida como ¨padrão-ouro¨, tendo indicações absolutas no tratamento cirúrgico da artrite séptica em crianças (especialmente no quadril), da nossa análise pode-se deduzir que esta opção rende os piores percentuais de resultados, dobrando o percentual de necessidade de lavagem adicional e o percentual de complicações, em comparação com a lavagem artroscópica. Existem outros métodos terapêuticos que se apresentam como procedimentos menos invasivos, seguros e eficazes, corroborados por bons resultados na biografia, tais como: a lavagem artroscópica (que apresentou a menor percentagem de doentes que necessitaram de lavagem adicional, com o maior número de artigos com boa resultados em geral, com percentual de complicações abaixo da lavagem por artrotomia) e lavagem por artrocentese (que apresentou o menor percentual de compilações das 3 opções analisadas).

Risk factors for infections after arthroscopic rotator cuff repair / 中国骨伤

OBJECTIVE@#To explore risk factors for infections after arthroscopic rotator cuff repair, and improve the under standing for reducing infection.@*METHODS@#Clinical data of 2 591 patients who underwent arthroscopic rotator cuff repair from January 2019 to January 2022 were retrospectively analyzed, including 1 265 males and 1 326 females, aged from 25 to 82 years old with an average age of (51.5±15.6) years old. They were divided into infection group(n=18) and uninfected group(n=2 573) according to whether or not patients had postoperative infection. Gender, age, smoking, diabetes, body mass index, local closure within 1 month before operation, operation time, preventive use of antibiotics, and internal fixation implantation between two groups were recorded. Univariate Logistic regression analysis screened factors associated with infections after arthroscopic rotator cuff repair. Theresultswere entered into the multivariate logistic regression analysis, screening the high risk factors for infections after arthroscopic rotator cuff repair.@*RESULTS@#In 2 591 patients, 18 patients were infected after operation, infection rate was 0.69%. Univariate Logistic regression analysis showed that gender, age, operation time, antibiotic prophylaxis, internal fixation implantation were risk factors for infections after arthroscopic rotator cuff repair. Multivariate Logistic regression analysis showed male(OR=14.227), age≥65 years(OR=34.313), operation time≥2 h (OR=15.616), without antibiotic prophylaxis(OR=4.891), and internal fixation implantation(OR=5.103) were major risk factors for infection after arthroscopic rotator cuff repair(P<0.05).@*CONCLUSION@#Male, age≥65 years, operation time≥2 h, without antibiotic prophylaxis and internal fixation implantation were independent risk factors for infection after arthroscopic rotator cuff repair. Early diagnosis and timely treatment should be carried out to reduce the incidence of infection.

Effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament tibial insertion fracture in adults / 中国修复重建外科杂志

OBJECTIVE@#To explore the effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament (PCL) tibial insertion fractures in adults.@*METHODS@#Between October 2019 and October 2021, 16 patients with PCL tibial insertion fractures were treated with arthroscopic binding fixation using suture through single bone tunnel. There were 11 males and 5 females with an average age of 41.1 years (range, 26-58 years). The fractures were caused by traffic accident in 12 cases and sports in 4 cases. The time from injury to operation ranged from 2 to 10 days with an average of 6.0 days. The fractures were classified as Meyers-McKeever type Ⅱ in 4 cases and type Ⅲ in 9 cases, and Zaricznyi type Ⅳ in 3 cases. There were 2 cases of grade Ⅰ, 7 cases of grade Ⅱ, and 7 cases of grade Ⅲ in the posterior drawer test. There were 3 cases combined with lateral collateral ligament injury and 2 cases with meniscus injury. The visual analogue scale (VAS) score, Lysholm score, International Knee Documentation Committee (IKDC) score, and knee range of motion were used to evaluate knee joint function. The posterior drawer test and knee stability tester (Kneelax 3) were used to evaluate knee joint stability. The X-ray films were used to evaluate fracture reduction and healing.@*RESULTS@#All incisions healed by first intention after operation. There was no incision infection, popliteal neurovascular injury, or deep venous thrombosis of lower limbs. All patients were followed up 6-12 months, with an average of 10 months. X-ray films at 6 months after operation showed the fractures obtained bone union. There were 11 cases of grade 0, 4 cases of gradeⅠ, and 1 case of grade Ⅱin posterior drawer test, showing significant difference when compared with preoperative results ( Z=23.167, P<0.001). The VAS score, Lysholm score, IKDC score, knee range of motion, and the results of Kneelax3 examination all significantly improved when compared with preoperative results ( P<0.05).@*CONCLUSION@#For adult patients with PCL tibial insertion fractures, the arthroscopic binding fixation using suture through single bone tunnel has the advantages of minimal trauma, good fracture reduction, reliable fixation, and fewer complications. The patient's knee joint function recovers well.

Mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion lesion / 中国修复重建外科杂志

OBJECTIVE@#To explore the mid-term effectiveness of arthroscopic "mini incision" transtendon repair for partial articular-sided supraspinatus tendon avulsion (PASTA) lesion.@*METHODS@#A clinical data of 39 patients with PASTA lesions, who underwent the arthroscopic "mini incision" transtendon repair and met the selected criteria between May 2017 and April 2021, was retrospectively analyzed. There were 13 males and 26 females, with an average age of 63.7 years (range, 43-76 years). Nine patients underwent trauma history, and no obvious inducement was found in the other 30 patients. The main clinical symptom was shoulder pain with positive hug resistance test. The interval from symptom onset to operation was 3-21 months (mean, 8.3 months). The visual analogue scale (VAS) score, University of California Los Angeles (UCLA) shoulder score, American Association of Shoulder and Elbow Surgeons (ASES) score and shoulder range of motion (ROM) of forward flexion, abduction, and external rotation were used to evaluate shoulder function. MRI was performed to assess the structural integrity and tension of reattached tendon. Patient satisfactions were calculated at last follow-up.@*RESULTS@#All incisions healed by first intention with no complications such as incision infection or nerve injury. All patients were followed up 24-71 months (mean, 46.9 months). The VAS, UCLA, and ASES scores significantly improved at 24 months after operation when compared with preoperative ones ( P<0.05). The ROMs of forward flexion and external rotation of the shoulder joint significantly increased at 3 and 24 months, and further increased at 24 months compared to 3 months, with significant differences ( P<0.05). However, the ROM of abduction of the shoulder joint at 3 months did not significantly improve compared with that before operation ( P>0.05), and it was significantly greater at 24 months than before operation and at 3 months after operation ( P<0.05). At last follow-up, the patients were very satisfied with the effectiveness in 30 cases (76.9%), satisfied in 5 cases (12.8%), and dissatisfied in 4 cases (10.3%). At 6 months after operation, 31 patients underwent reviews of MRI scans, of which 28 patients possessed intact structural integrity, good tendon tension and tendon healing, and 3 patients underwent tendon re-tear.@*CONCLUSION@#Arthroscopic "mini incision" transtendon repair in treatment of PASTA lesion could obtain satisfying mid-term effectiveness with low risk of tendon re-tear.

Progress in diagnosis and hip arthroscopic treatment of borderline developmental dysplasia of hip with Cam-type femoroacetabular impingement / 中国修复重建外科杂志

OBJECTIVE@#To summarize the biomechanical characteristics, diagnosis, and hip arthroscopic treatment of borderline developmental dysplasia of hip (BDDH) with Cam-type femoroacetabular impingement (Cam FAI).@*METHODS@#The literature on BDDH with Cam FAI at home and abroad in recent years was extensively reviewed and analyzed.@*RESULTS@#In patients with BDDH and Cam FAI, the femoral neck anteversion angle and femoral neck shaft angle increase, the pelvis tilts, and the acetabulum rotates, resulting in instability of the hip joint. In order to maintain the stability of the hip joint, the direction of biomechanical action of the hip joint has changed, which further affects the anatomical structures such as the proximal femur and acetabular morphology. BDDH with Cam FAI can be diagnosed clinically by combining lateral center edge angle, anterior center edge angle, and acetabular index. BDDH with Cam FAI can be effectively treated through arthroscopic polishing of the edges of the acetabular proliferative bone, excision of Cam malformations, and minimally invasive repair of the glenoid lip and cartilage of the hip joint.@*CONCLUSION@#Currently, there is no unified standard for the diagnosis and treatment of BDDH with Cam FAI. Minimally invasive treatment of the hip under arthroscopy can achieve good early- and medium-term effectiveness, and has certain advantages in repairing and maintaining the integrity of the glenoid lip and suturing/compression joint capsule. However, the long-term effectiveness needs to be further followed up to determine. The timing of surgery, intraoperative bone edge depth polishing, and joint capsule suturing/compression techniques also need to be further explored.

Effectiveness analysis of "tail compression fixation+suture bridge" technology under shoulder arthroscopy for treating primary tear in medial enthesis of rotator cuff / 中国修复重建外科杂志

OBJECTIVE@#To investigate the feasibility and effectiveness of "tail compression fixation+suture bridge" technology under shoulder arthroscopy for treating primary tear in medial enthesis of rotator cuff.@*METHODS@#The clinical data of 11 patients with primary tear in medial enthesis of rotator cuff who met the selection criteria between October 2020 and October 2022 were retrospectively analyzed, including 3 males and 8 females, aged 39-79 years, with an average of 61.0 years. Rotator cuff injury was caused by traumatic fall in 8 cases, and the time from injury to admission was 1-4 months, with an average of 2.0 months; the remaining 3 cases had no obvious inducement. The active range of motion of the affected shoulder was limited, with an active forward flexion range of motion of (64.1±10.9)°, abduction of (78.1±6.4)°, internal rotation of (48.2±6.6)°, and external rotation of (41.8±10.5)°; 5 cases had shoulder stiffness. The preoperative visual analogue scale (VAS) score was 7.8±0.8 and the American Society of Shoulder and Elbow Surgeons (ASES) score was 23.9±6.4. The patients were treated with "tail compression fixation+suture bridge" technology under shoulder arthroscopy, and the pain and functional recovery were evaluated by VAS score, ASES score, and active range of motion of shoulder joint at last follow-up; MRI was performed after operation, and the integrity of rotator cuff was evaluated by Sugaya classification system.@*RESULTS@#All the 11 patients were followed up 2-22 months, with an average of 13.5 months. All incisions healed by first intention, and there was no complication such as infection, rotator cuff re-tear, and anchor falling off. At last follow-up, the VAS score was 0.8±0.7 and the ASES score was 93.5±4.2, which significantly improved when compared with those before operation ( P<0.05). All 11 patients had no significant swelling in the shoulders, and the active range of motion was (165.1±8.8)° in flexion, (75.3±8.4)° in abduction, (56.6±5.5)° in internal rotation, and (51.8±4.0)° in external rotation, which significantly improved when compared with those before operation ( P<0.05). Shoulder MRI showed adequate tendon thickness and good continuity in 9 cases, including 4 cases with partial high signal area; and 2 cases with inadequate tendon thickness but high continuity and partial high signal area. According to Sugaya classification system, there were 4 cases of type 1 (36.4%), 5 cases of type 2 (45.5%), and 2 cases of type 3 (18.1%).@*CONCLUSION@#For the patients with primary tear in medial enthesis of rotator cuff, the "tail compression fixation+suture bridge" technology under shoulder arthroscopy is simple and effective.
