OBJECTIVE@#To summarize the clinical features, surgical methods, and prognosis of bucket-handle meniscal tears (BHMTs), and provide guidance for clinical treatment.@*METHODS@#The clinical data of 91 BHMTs patients (91 knees), who met the selection criteria and were admitted between January 2015 and January 2021, was retrospectively analyzed. There were 68 males and 23 females. Age ranged from 16 to 58 years with an average of 34.4 years. The injury was caused by sports in 68 cases, traffic accident in 15 cases, and falls or sprains in 8 cases. There were 49 cases of left knee injury and 42 cases of right knee injury. The time from the onset of symptoms to the admission ranged from 1 day to 13 months (median, 18 days), including >1 month in 35 cases and ≤1 month in 56 cases. Medial BHMTs occurred in 52 cases and lateral BHMTs in 39 cases. There were 36 cases with ACL rupture and 12 cases with discoid meniscus. The knee extension was limited more than 10° in 55 cases. According to the condition of meniscus injury, the meniscus suture with Inside-out combined with All-inside techniques (54 cases) or meniscoplasty (37 cases) under arthroscopy were selected. ACL reconstruction was performed in all patients with ACL rupture with autogenous hamstring tendon. Postoperative complications were observed. International Knee Documentation Committee (IKDC) score, Lysholm score, and Tegner score were used to evaluate knee function, and clinical failure was recorded.@*RESULTS@#Two patients developed intermuscular venous thrombosis, which improved after oral anticoagulant therapy. No vascular injury, postoperative infection, joint stiffness, or other complications occurred in all patients. All patients were followed up 24-95 months, with a median of 64 months. A total of 12 cases (13.19%) failed the operation and were re-operated or given oral anti-inflammatory analgesics and rehabilitation therapy. At last follow-up, IKDC score and Lysholm score of 91 patients significantly increased when compared with those before operation ( P<0.05), while Tegner score significantly decreased ( P<0.05). The above indexes of patients treated with meniscus suture and meniscoplasty were also significantly different from those before operation ( P<0.05).@*CONCLUSION@#BHMTs occurs mostly in young men and is one of the important reasons for the limitation of knee extension after trauma. Arthroscopic meniscus suture and meniscoplasty can obtain good effectiveness according to individual conditions of patients. But the latter can better preserve the shape and function of meniscus, and theoretically can obtain better long-term outcomes, which needs to be confirmed by further research with larger sample size.

ABSTRACT Introduction: Meniscal injury is a common condition that can lead to disability due to pain and proprioceptive failure, requiring immediate attention. Combination therapies involve advanced approaches aiming to accelerate rehabilitation in athletes, and electroacupuncture presents therapeutic benefits, although there is still no evidence of its combination with sports therapy. Objective: This paper analyzes the performance of sports rehabilitation in athletes with meniscal lesions using electroacupuncture combined with sports therapy. Methods: The intervention in the control group was based on a traditional range of motion work, muscle strength, proprioceptive training, and other exercise therapies, while the experimental group received a 30 min electro-acupuncture protocol three times a week for four consecutive weeks. The surrogate data (gender, age, disease course, location) are the same. Before treatment, joint activity, muscle strength, total joint scale score of the LYSHOLM questionnaire, and other observational indices were measured during the 6th and 12th week of treatment. The non-parametric statistical method and T-test were used to analyze the changes of each index before and after treatment. After 12 weeks of treatment, the difference between the experimental group and the combination before treatment was significant. Results: The treatment effect of the experimental group was significantly better than the control group. Conclusion: The effect of sports rehabilitation of athletes with meniscus injury based on electroacupuncture combined with sports therapy showed high resolutive application value, indicating an alternative for non-surgical treatment in knee meniscus injuries. Level of evidence II; Therapeutic studies - investigation of treatment outcomes.

RESUMO Introdução: A lesão meniscal é um acometimento comum que pode gerar incapacitação por dor e falha proprioceptiva, exigindo atenção imediata. Terapias combinadas envolvem abordagens avançadas com o objetivo de acelerar a reabilitação nos atletas, e a eletroacupuntura apresenta benefícios terapêuticos, embora ainda não possua evidencias de sua combinação com a terapia esportiva. Objetivo: Analisar o desempenho da reabilitação esportiva em atletas com lesão meniscal utilizando eletroacupuntura combinada à terapia esportiva. Métodos: A intervenção no grupo controle baseou-se no trabalho tradicional de amplitude de movimento, força muscular, treinamento proprioceptivo e outros tipos de terapias de exercício enquanto que ao grupo experimental foi adicionado um protocolo de eletro-acupuntura de 30 minutos de duração, 3 vezes por semana durante 4 semanas consecutivas. Os dados de substituição (sexo, idade, curso de doença, localização) são basicamente os mesmos. Antes do tratamento, a atividade articular, a força muscular, o escore total da escala articular do questionário LYSHOLM e outros índices de observação foram medidos na 6ª e 12ª semana do tratamento. O método estatístico não paramétrico e teste-T foram utilizados para analisar as alterações de cada índice antes e depois do tratamento. Após 12 semanas de tratamento, a diferença entre o grupo experimental e a combinação antes do tratamento foi significativa. Resultados: O efeito de tratamento do grupo experimental foi significativamente melhor do que o grupo controle. Conclusão: O efeito de reabilitação esportiva de atletas com lesão meniscal baseada em eletroacupuntura combinada à terapia esportiva demonstrou alto valor de aplicação resolutiva, indicada como alternativa para o tratamento não cirúrgico em lesões no menisco do joelho.

Abstract The first meniscal suture was performed in 1885 and took about a century to become popular. Currently, all-inside meniscal repair devices are widely used. However, this technique presents the disadvantage of being a method dependent on specific devices, presenting a higher cost than other techniques. This high cost limits the use of such a technique in many locations. The objective of the present technical note is to describe a microinvasive meniscal suture technique as a modification of the all-inside technique, using a disposable 40 x 12 mm procedure needle. The authors believe that the proposed modification to the technique can make it more popular, enabling the use of the microinvasive technique in places with limited resources.

Resumo A primeira sutura meniscal foi realizada em 1885 e levou cerca de um século para tornar-se popular. Atualmente, os dispositivos de reparo meniscal all-inside são amplamente utilizados. Contudo, esta técnica apresenta a desvantagem de ser um método dependente de dispositivos específicos, apresentando um custo superior aos de outras técnicas. Este valor elevado limita o uso de tal técnica em muitos locais. O objetivo da presente nota técnica é descrever uma técnica de sutura meniscal microinvasiva, como uma modificação da técnica all-inside, utilizando uma agulha descartável de procedimento de 40 x 12 mm. Os autores acreditam que a modificação proposta para a técnica pode torná-la mais popular, possibilitando o uso da técnica microinvasiva em locais com recursos limitados.

Introducción: El objetivo del siguiente trabajo es mostrar los resultados clínicos de una serie de pacientes mayores de cuarenta años, tratados con reparación meniscal, evaluar detalles de las técnicas utilizadas, índice y causa de fallas y vuelta al deporte. Materiales y métodos: analizamos retrospectivamente pacientes intervenidos quirúrgicamente por nuestro equipo entre enero de 2012 y enero de 2018, a los que se les realizó reparación de lesión meniscal, asociada o no a lesión de LCA. Se excluyeron los pacientes menores de cuarenta años, aquellos con cirugías previas y seguimiento menor a cuatro años. Resultados: evaluamos cuarenta pacientes con edad promedio de cuarenta y ocho años (rango 40­61). El seguimiento promedio fue de sesenta y seis meses (rango 48­84). El promedio de suturas utilizadas fue 3 (rango 1 a 8 puntos). Cinco pacientes presentaron fallas (12.5%): cuatro asociadas a plástica de LCA y la restante por una reparación aislada. Los scores de Lysholm, IKDC y Tegner mostraron mejoría en el postoperatorio. Conclusión: según la evidencia disponible hasta la fecha, y los muy buenos resultados obtenidos en este estudio con un índice de falla del 12.5%, la edad, como factor independiente, no debe ser tomada como una contraindicación para la reparación meniscal. La reparación meniscal en pacientes mayores de cuarenta años tiene índices de fallas comparables a las reparaciones realizadas en pacientes jóvenes después de cuatro años de seguimiento. Nivel de Evidencia: IV

Purpose: Our aim is to evaluate clinical results in a series of meniscal repair in patients over forty years old. Reviewing the used technique, index and failure cause and return to sport. Materials and methods: we retrospectively reviewed our patients who underwent an arthroscopic meniscal repair between January 2012 and January 2018, with or without concomitant ACL reconstruction surgery. We excluded patients under forty years old, previous surgery, and a follow up of less than four years. Results: forty patients met our criteria. Mean age was forty-eight years old (range 40­61). The mean follow-up was of sixty-six months (range 48­84). The average number of sutures needed to make the repair was of three (range 1­8 sutures). Five patients failed (12.5%), four had an associated ACL reconstruction surgery and the latter was an isolated repair. Lysholm Score, IKDS and Tegner Score showed great results in the post-operative period. Conclusion: as more and more patients remain active into adulthood, the ability to preserve native meniscal tissue after injury is an important goal. According to the available evidence published so far, and our very promising results shown in this study with a 12.5% failure rate, age as an independent factor should not be considered as a non-repairing factor. Meniscal repair in patients over forty years old present similar results and failure rate comparable to repairs in younger patients after four years of follow-up. Level of Evidence: IV

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.

OBJECTIVE@#To bring forward an arthroscopic classification of the popliteal hiatus of the lateral meniscus (PHLM) tears and to assess the effects of arthroscopic all-inside repair with suture hook in management of such injuries.@*METHODS@#This study involved 146 patients who underwent arthroscopic operation because of PHLM tears from April 2014 to October 2017, eliminating the patients who had discoid lateral meniscus. There were 81 males and 65 females, with 54 left knees and 92 right knees. The average ages were (34.7±3.7) years. Among the selected participants, there were 107 patients with anterior cruciate ligament (ACL) injuries, 39 patients with medial collateral ligament (MCL) injuries, and 48 patients with medial meniscus tears. The average preoperative Lysholm and International Knee Documentation Committee (IKDC) scores were 57.7±9.2 and 54.1±8.9, respectively. The arthroscopic classification was based on the extent and degree of PHLM tears and using the arthroscopic all-inside repair with suture hook for such injuries. For the patients associated with ACL injuries, the ipsilateral autograft hamstring tendons use as the reconstruction graft for single bundle ACL reconstructions. The suture anchors were used for treatment of MCL Ⅲ injuries, and the arthroscopic all-inside repair for medial meniscus tears.@*RESULTS@#A total of 146 PHLM tears in 146 patients were divided into type Ⅰ (tears not involved in popliteus tendon incisura; n=86, 58.9%), type Ⅱ (tears involved in popliteomeniscal fascicles; n=36, 24.7%), and type Ⅲ (tears involved in popliteus tendon incisura; n=24, 16.4%). For type Ⅰ, there were three subtypes, including type Ⅰa: longitudinal tear (n=53, 61.6%), type Ⅰb: horizontal tear (n=27, 31.4%), and type Ⅰc: radial tear (n=6, 7.0%). For type Ⅱ, there were also three subtypes, including type Ⅱa: anterosuperior popliteomeniscal fascicle tear (n=5, 13.9%), type Ⅱb: posterosuperior popliteomeniscal fascicle tear (n=20, 55.6%), and type Ⅱc: both tears (n=11, 30.6%). For type Ⅲ, there were two subtypes, including type Ⅲa: horizontal tear (n=9, 37.5%), type Ⅲb: radial tear (n=15, 62.5%). In the follow-up for an average of 15.3±2.6 months, all the patients had done well with significantly improved Lysholm (84.6±14.3) and IKDC (83.2±12.8) scores at the end of the last follow-up relative to preoperative scores (P > 0.01).@*CONCLUSION@#We propose that it is possible to classify lateral meniscus tears at the popliteal hiatus region for three types, which can summarize the injury characteristics of this area. The arthroscopic all-inside repair with suture hook for the PHLM tears can avoid stitching to popliteal tendon or narrowing popliteal hiatus and have satisfactory clinical results.

SUMMARY: Meniscus tear is an important injury affecting the quality of life. This work is aimed to investigate the activity of CD68 and ADAMTS-5 in cells in synovial fluid in male and female patients with meniscal tear. In this study ,18 male and 22 female patients with meniscal tears were included. Local pain sensation during patients' physical examination, swelling, performing daily activities and difficulty in running-walking complaints were determined. 5 cc synovial fluids were aspirated from the lateral suprapatellar pouch part of the knees with meniscal pain. After routine histological follow-up of the samples, they were embedded in paraffin and sectioned with microtome and 5 micrometer thickness. CD68 and ADAMTS-5 primary antibodies were used for immunohistochemical analysis. Sections were taken and evaluated with a stylish microscope. The distribution of blood cells after meniscus tear was higher in female patients than in male patients. CD68 distribution in female patients appeared higher than in male patients. CD68 expression was high in macrophage cell cytoplasm. ADAMTS-5 expression was higher in female patients in degenerative cells and apoptotic cells. ADAMTS-5 is an important metallo-protein involved in the development of apoptotic signal and extracellular matrix synthesis in patients with ADAMTS-5 meniscus tear, and it may be an important criterion for the treatment developed after injury. CD68 and ADAMTS-5 activity was thought to be one of the important signal pathways that can be identified in the treatment of meniscus tear.

RESUMEN: La rotura del menisco es una lesión importante que afecta la calidad de vida. El objetivo fue investigar la actividad de CD68 y ADAMTS-5 en células del líquido sinovial en pacientes masculinos y femeninos con desgarro meniscal. Se incluyeron 18 pacientes masculinos y 22 femeninos con desgarros meniscales. Se determinó la sensación de dolor local durante el examen físico de los pacientes, la hinchazón, la realización de actividades diarias y la dificultad al correr y caminar. Se aspiraron 5 cc de líquido sinoviale de la parte de la bolsa suprapatelar lateral de las rodillas de los pacientes con dolor meniscal. Después del seguimiento histológico de rutina, las muestras se incluyeron en parafina y se seccionaron con un micrótomo de grosor de 5 micrómetros. Para el análisis inmunohistoquímico se usaron los anticuerpos primarios CD68 y ADAMTS-5. La distribución de las células sanguíneas después del desgarro del menisco fue mayor en pacientes femeninos que en pacientes masculinos. La distribución de CD68 en pacientes femeninos fue más alta que en pacientes masculinos. Además la expresión de CD68 fue alta en el citoplasma de los macrófagos. La expresión de ADAMTS-5 fue mayor en pacientes femeninos en las células degenerativas y células apoptóticas. ADAMTS-5 es una metaloproteína importante en el desarrollo de la señal apoptótica y la síntesis de matriz extracelular en pacientes con rotura de menisco ADAMTS-5, y puede ser un criterio importante para el tratamiento después de la lesión. La actividad de CD68 y ADAMTS-5 era una de las vías de señal importantes que se pueden identificar en el tratamiento de la rotura del menisco.

Dada la creciente popularidad de las actividades deportivas, el número de roturas del ligamento cruzado anterior (LCA) y lesiones meniscales ha aumentado en particular en niños y adolescentes. El manejo de estas lesiones es desafiante debido las fisis abiertas. Por un lado las opciones de reconstrucción del LCA incluyen técnicas: transfisarias, extra-articulares y intraepifisarias. Por otro lado se han descrito diferentes técnicas de reparación meniscal: "all-inside", "inside-out" y "outside-in". Estas tiene como objetivo lograr la cicatrización meniscal, evitando los efectos adversos de la meniscectomía. Presentamos un reporte de caso de un adolescente de 14 años con una rotura completa del LCA y una lesión del cuerno posterior del menisco interno que fue sometido a una reconstrucción transfisaria del LCA y a una reparación meniscal "inside-out".

With the raising popularity of sporting activity, the number of anterior cruciate ligament (ACL) ruptures and meniscal tears has increased in particular in children and adolescents. Management of these injuries is challenging due to open growth plates. On the one hand the ACL reconstructions options includes: transphyseal, extra-articular and epiphyseal-only techniques. On the other hand there have been described different meniscal repair techniques: "all-inside", "inside-out" and "outside-in". These aim to achieve meniscal healing, avoiding the adverse effects of meniscectomy. We present a case report of a 14-year adolescent with an ACL complete rupture and a posterior horn tear of the medial meniscus who underwent an ACL transphyseal reconstruction and a "inside-out" meniscal repair.

Dada a crescente popularidade das atividades esportivas, o número de rupturas do ligamento cruzado anterior (LCA) e lesões meniscais aumentou especialmente em crianças e adolescentes. O manejo destas lesões é desafiador devido às fissuras abertas. Por um lado as opções de reconstrução do LCA incluem técnicas: transfisárias, extra-articulares e intraepifisárias. Por outro lado, foram descritas diferentes técnicas de reparação meniscal: "all-inside", "inside-out" e "outside-in". Estes têm como objetivo alcançar a cicatrização meniscal, evitando os efeitos adversos da meniscectomia. Apresentamos um relatório de caso de um adolescente de 14 anos com uma ruptura completa do LCA e uma lesão do corno posterior do menisco interno que foi submetido a uma reconstrução transfisária do LCA e a uma reparação meniscal "inside-out".

Discoid meniscus injury is a kind of common sports injury. Its treatment methods include arthroscopic discoid meniscus plasty, discoid meniscus subtotal resection, discoid meniscus total resection and so on. Although the short-term clinical effect is good, the long-term clinical effect is not ideal. At present, different scholars have different views on the choice of surgical methods for discoid meniscus injury. In recent years, many scholars have shown that the choice of operation and the change of lower limb force line are related to the therapeutic effect of discoid meniscus injury. This paper mainly summarizes the current situation of the treatment of discoid meniscus injury and the changes of the force line of the lower limbs after operation, and expounds therole of the evaluation of the force line of the lower limbs in the treatment of discoid meniscus, so as to provide the basis for the clinical individualized treatment of discoid meniscus injury.

Las estructuras intraarticulares, como el cartílago, el ligamento cruzado anterior (LCA) y los meniscos tienen un potencial de cicatrización limitado una vez que se lesionan. Un mayor conocimiento de las ciencias básicas y el advenimiento de las terapias biológicas han creado un gran interés en la utilización de diferentes estrategias de aumentación, cuyo objetivo es facilitar el proceso de cicatrización de dichas estructuras de la rodilla. Nuestro propósito es presentar una revisión de los conceptos actuales sobre las terapias biológicas en artroscopía de rodilla.Se realizó una revisión de la literatura que incluyó búsquedas en las bases de datos PubMed, Medline, Embase y Cochrane, utilizando las siguientes palabras clave: terapias biológicas, lesión del LCA, lesión meniscal, lesión del cartílago articular, PRP, BMAC, Bio-Ortopedia y Ortobiológicos.Se ha reportado que la utilización de técnicas biológicas de aumentación, incluidas el plasma rico en plaquetas (PRP), la médula ósea concentrada (BMAC) y otras terapias celulares para lesiones del cartílago articular, del LCA y de los meniscos podría facilitar el proceso de cicatrización con resultados clínicos prometedores.Podemos concluir que, efectivamente, existe un creciente interés en la utilización de terapias biológicas en las lesiones de rodilla con resultados clínicos heterogéneos, pero promisorios. Se necesitan estudios adicionales, randomizados, prospectivos, controlados y comparativos para determinar la eficacia real de las diferentes estrategias de aumento biológico en el entorno clínico

Intra-articular structures such as articular cartilage, anterior cruciate ligament (ACL), and menisci have limited healing potential after injury. The greater knowledge of the basic sciences and the advent of biological therapies have created a great interest in the use of different augmentation strategies, whose objective is to facilitate the healing process of these knee structures.To present a current concept review on the use of biological therapies in knee arthroscopy.A literature review was performed that included searches of the PubMed, Medline, Embase and Cochrane databases using the following keywords: Biological therapies, ACL tears, meniscal tears, articular cartilage injury, PRP, BMAC, Bio-Orthopaedics and Orthobiologics.It has been reported that the use of biological augmentation techniques, including Platelet rich plasma (PRP), bone marrow aspirate concentrate (BMAC), and other cellular therapies for injuries to articular cartilage, ACL, and menisci, could facilitate the healing process with promising clinical results.There is a growing interest in the use of biological therapies in knee injuries with heterogeneous but promising clinical results. Additional, randomized, prospective, controlled, and comparative studies are needed to determine the true efficacy of different biological augmentation strategies in the clinical setting

El menisco cumple un rol clave en la distribución de cargas, ampliando la superficie de contacto y mejorando la congruencia femorotibial. La lesión meniscal aumenta exponencialmente presiones y altera el área de contacto articular femorotibial. Evaluaremos la efectividad de reparaciones artroscópicas en lesiones meniscales aisladas y la tasa de retorno al deporte competitivo de contacto.Se evaluaron retrospectivamente once pacientes tratados con sutura meniscal artroscópica aislada, con un seguimiento mínimo de dos años. Criterios de inclusión: lesión meniscal aislada aguda o semi aguda (0-6 semanas), lesiones longitudinales zona roja-roja y zona roja-blanca, deporte competitivo de contacto. Criterios de exclusión: reparación meniscal asociada a otros procedimientos (por ejemplo, plástica del LCA), cirugía de revisión. Sexo: diez hombres, una mujer. Edad: mediana de veinticuatro años (14-35).Complicaciones: un paciente con pérdida de extensión >5°. Retorno al deporte: diez pacientes mismo deporte / mismo nivel, un paciente a menor nivel. Re-ruptura: un paciente, nueva entorsis en su tercera temporada postcirugía. Subjetivamente: diez pacientes muy satisfechos, uno regular. Podemos concluir que pacientes jóvenes con lesiones meniscales aisladas, reparadas artroscópicamente en las primeras seis semanas, tienen una excelente tasa de retorno al deporte competitivo de contacto, con alto grado de satisfacción. Nivel de Evidencia: IV

Our objective is to evaluate the effectiveness of isolated meniscal repairs and the rate of return to competitive sports and compare them with the literature.The meniscus plays a role in shock absorption, load distribution, increases the contact surface, improves femoral-tibial congruence. The meniscal injury alters the transmission of loads, thus increasing the pressures of the femoral-tibial contact between 20 and 50%.Eleven patients with eleven meniscal lesions treated with isolated arthroscopic meniscal suture were retrospectively evaluated. Inclusion criteria: patient with isolated acute or semi-acute meniscal injury (0-6 weeks), competitive contact sport.Eleven patients (eleven knees), minimum follow-up two years. Ten men, one woman. Median age twenty four years (14-35). Meniscal lesions: four red-red zone and seven red-white zone. Median time from injury to surgery: four weeks (1-13). Ten patients returned to their sport at the same level. One patient return to sport but at a lower level. The median time of return to the sport: sixteen weeks (12-28). Two dropouts of sport: one patient after a second competitive season, for reasons not related to surgery; one patient suffered a re-injury that required partial meniscectomy.Subjectively: Very satisfied ten patients, regular one patient. Complications: loss of extension more than 5° one patient. Pain: climatic discomfort in three patients, pain with maximum training loads in one patient.Young patients with simple red-red or red-white lesions, operated on within the first six weeks from injury have excellent clinical results and return to contact sport at same level.

The present study aimed to evaluate the inter- and intra-observer reproducibility of the arthroscopic meniscus tear classification system in patients treated with meniscal suture, as well as to correlate these anatomical zones, according to the injury characteristics and the suture technique employed.Forty-six knee arthroscopies were analyzed for meniscal sutures. The evaluators recorded data of the zones described by Smigielski, types of injuries, meniscal vascularity, suture techniques, and types of suture knots applied to sutures. Data were analyzed with respect to inter and intra-observer agreement. All clinical and anatomical outcomes as well as the characterization of the injury and meniscal treatment were correlated.The intra- and inter-observer reproducibility (Kappa coefficient) for the arthroscopic classification system of meniscus injury proposed by Smigielski ranged from slight to moderate.The zone classification defines the menisci and their relationship with the surrounding anatomic landmarks of the knee; however, it has limited arthroscopic application. The practical knowledge of the classification system described in this study can help specifically guide treatment for various types of meniscal injury

El propósito del presente estudio es evaluar la reproducibilidad inter e intraobservador de la clasificación artroscópica de lesiones meniscales propuesta por Smigielski en pacientes tratados con suturas meniscales, así como correlacionar las zonas anatómicas con las características lesionales y el tipo de técnica de sutura empleada.Se analizaron cuarenta y seis artroscopías de rodilla con sutura meniscal de la lesión. Se examinó la zona descripta según Smigielski, el tipo de lesión meniscal, la vascularidad, la técnica de sutura meniscal y el tipo de nudo empleados. Los datos fueron evaluados para considerar la reproducibilidad intra e interobservador. Todos los resultados clínicos, anatómicos, características de la lesión, así como el tratamiento meniscal utilizado, se correlacionaron.La correlación intra e interobservador (coeficiente Kappa) para la clasificación artroscópica de lesiones meniscales propuesta por Smigielski fue leve o moderada. La clasificación por zonas que define la lesión meniscal y su relación con las estructuras anatómicas de la rodilla tiene aplicación limitada en la cirugía artroscópica. El conocimiento práctico de la clasificación podría servir como guía para la toma de conducta ante las lesiones meniscales reparables

Introducción Las lesiones de la raíz posterior del menisco lateral (RPML) afectan la transferencia de la carga axial de la rodilla, lo cual genera una sobrecarga con el posterior deterioro del cartílago articular. Se han descrito numerosas técnicas quirúrgicas en la literatura para su tratamiento, pero aún no se ha demostrado superioridad de alguna, por ende, existen controversias sobre cual técnica es la más indicada para estas lesiones. El objetivo del estudio es describir la técnica quirúrgica y la evolución clínica de pacientes intervenidos con fijación transtibial de la RPML en una clínica especializada, durante el periodo 2016-2017. Materiales & Métodos Se realizó una descripción de la técnica quirúrgica y una serie de casos retrospectiva. Se incluyeron pacientes con lesiones agudas en la RPML, los cuales fueron intervenidos quirúrgicamente utilizando una nueva variación a técnica transtibial. Para determinar la evolución cínica de los pacientes se realizaron las escalas Lysholm e IKDC, antes y después de la cirugía. Resultados Se intervinieron seis pacientes con lesión aguda de la RPML, cuatro de sexo masculino. El tiempo entre el trauma y la cirugía fue en promedio 2,5 meses. Todos los pacientes presentaron lesión concomitante de ligamento cruzado anterior. Al comparar el estado inicial de los pacientes y el postoperatorio mediante las escalas de Lysholm e IKDC, se encontraron diferencias estadísticamente significativas (p<0,05). Asimismo, no se realizaron reintervenciones durante el seguimiento. Discusión La reparación de la RPML con la nueva variación de la fijación transtibial proporciona una mejoría en la función, el dolor y el nivel de actividad de los pacientes, lo que puede ayudar a retrasar la progresión de la osteoartrosis en la rodilla. Igualmente, este procedimiento se puede realizar de forma segura aún en casos de lesiones ligamentarías concomitantes. Nivel de evidencia: IV

Background injuries of posterior lateral meniscus root (PLMR) affect the transfer of the axial load of the knee. Several surgical techniques have been described for it treatment, but still none has demonstrated superiority. Consequently, there are controversies about which technique is most indicated for these injuries. The aim is to describe the a surgical technique and the clinical follow up of patients operated with transtibial fixation of PLMR in a specialized clinic, during the 2016-2017. Methods Retrospective case series and description of the surgical technique. We included patients with acute injuries in the PLMR, who were operated using a new variation to the transtibial technique. For the clinical follow-up, the IKDC and Lysholm scores were performed before and after surgery. Results Six patients with acute lesion in the PLMR were intervened, four were male. The time between trauma and surgery was on average 2.5 months. All the patients presented a concomitant lesion of the anterior cruciate ligament. When comparing the initial state of the patients and the postoperative period, statistically significant differences were found (p <0.05). Likewise, reinterventions were not performed during follow-up. Discussion The repair of PLMR with the new variation of the transtibial fixation provides an improvement in the function, the pain and the level of activity of the patients, which can help to delay the progression of osteoarthrosis in the knee. Likewise, this technique can be performed safely even in cases of concomitant ligament injuries. Level of clinical evidence: Level IV

Introducción: El propósito de este trabajo fue evaluar retrospectivamente los resultados funcionales de una serie de pacientes con lesiones meniscales, tratados mediante la sutura artroscópica del menisco con técnica fuera dentro y describir la técnica quirúrgica.Material y métodos: Se analizaron retrospectivamente 49 suturas meniscales artroscópicas de rodilla. Cuarenta fueron aisladas y 9 asociadas a rupturas del LCA. Treinta y dos fueron hombres y 17 mujeres, con una edad promedio de 24 años (12- 40), y con un seguimiento promedio de 58 meses. Treinta y seis pacientes fueron tratados solo con técnica fuera dentro y en 13 pacientes se utilizó una técnica híbrida combinando una sutura fuera dentro con dispositivos todo dentro. Se realizó una evaluación clínica con el escore de Lysholm y con el International Knee Documentation Committee (IKDC), en el pre operatorio y en el último control. Resultados: Se observo una ruptura de la reparación en 7 pacientes (15%), 6 traumáticas durante una actividad deportiva, y una espontánea. Las lesiones del menisco interno y las rupturas en asa de balde presentaron un mayor índice de falla, sin que esta diferencia sea significativa. No se observaron diferencias clínicas al comparar el grupo de pacientes con técnica fuera dentro y en aquellos que se realizó una técnica hibrida. Conclusión: La cirugía de preservación meniscal con la técnica fuera-dentro nos permitió obtener resultados funcionales favorables en casos seleccionados.Tipo de estudio: Serie de casos Nivel de evidencia: IV

Introduction: The purpose of this study was to retrospectively evaluate the functional results of a series of patients with meniscal lesions treated by arthroscopic meniscal suture with the outside in technique and describe the surgical technique.Material and Methods: 49 arthroscopic meniscal knee sutures were retrospectively analyzed. Forty were isolated and 9 associated with ACL ruptures. Thirty-two were men and 17 women with an average age of 24 years (12-40), and with an average follow-up of 58 months. Thirty-six patients were treated only with outside in technique and in 13 patients a hybrid technique was used combining a suture outside inside with devices all inside. A clinical evaluation was performed with the Lysholm score and the International Knee Documentation Committee (IKDC) in the preoperative and in the last control.Results: A re-rupture is observed in 7 patients (15%), 6 traumatic during a sport activity, and a spontaneous one. Medial meniscus and bucket handle repairs have a major failure rate, without significant difference. No clinical differences were observed when comparing the group of patients with outside in technique and in those who performed a hybrid technique.Conclusion: Meniscal preservation surgery with the outside in technique allows us to obtain favorable functional results in selected cases. Type of study: Case series. Level of evidence: IV

OBJECTIVE@#To investigate the clinical effect of a modified arthroscopic outside-in suture technique in the treatment of meniscus tear using a spinal needle.@*METHODS@#From January 2015 to October 2017, 95 patients treated with this method were followed-up. Among these cases, there were 36 males and 59 females. The age of the patients ranged from 16 to 77 years, (46.79±18.07) years in average. Among them, there were 28 patieats aged 16-35, 53 patients aged 36-65, and 14 patients aged over 65 years old. 28 cases were diagnosed with medial meniscus tear, 43 cases with lateral meniscus tear and 24 cases with both medial and lateral meniscus tear. Causes of the injury included sports, sprain, etc. According to Barrett standard, the clinical healing of meniscus tear was judged. Lysholm score, knee range of motion, visual simulation score (VAS) and magnetic resonance imaging (MRI) were used to evaluate the postoperative knee function and recovery of the patients.@*RESULTS@#The 95 patients were followed up for 22 to 36 months, with an average of (28.32±3.98) months. According to Barrett standard, 90 patients (94.7%) obtained meniscus clinical healing. Meniscal healing rates were 96.43%, 96.23% and 85.71% in the three age groups, respectively. The meniscal healing rate was lower in the elderly group, but there was no significant difference in statistical results (P=0.262). Five patients had deep tenderness in the joint space of the injured side, and the overstretch test was positive. The preoperative and postoperative VAS scores, Lysholm scores and knee motion were compared in each group, and the differences were statistically significant (P < 0.01). At the end of the last follow-up, there were no cases of knee joint effusion, swelling and interlocking, and the joint function was effectively improved in most patients. No surgical site infection, periarticular vascular/nerve injury or knotting reaction was found during the follow-up.@*CONCLUSION@#This modified arthroscopic outside-in suture technique using a spinal needle has the characteristics of simple operation, small trauma and rapid recovery, and the mid-term follow-up results were satisfactory. Therefore, we consider this method to be a safe and efficient method for the treatment of meniscus anterior horn and body tear.

As lesões dos meniscos são uma das principais causas de dor e claudicação em equinos. O objetivo do presente estudo foi avaliar a morfometria dos meniscos da articulação femorotibial de equinos. Foram utilizados 48 meniscos de 12 animais de ambos os sexos, com idade entre cinco e 15 anos e com peso entre 400kg e 500kg. A medida da extensão periférica compreendeu desde a parte mais cranial à mais caudal e denominou-se circunferência externa (CE). A margem interna, com o mesmo tratamento, foi chamada de circunferência interna (CI). Os meniscos foram divididos em terços craniais, médios e caudais. A espessura foi obtida nos pontos médios de cada terço. Foi calculada a área dos meniscos em contato com os côndilos femorais. O menisco medial apresentou maior CE com média de 126,38mm, enquanto o menisco lateral apresentou média de 115,32mm. O menisco lateral mostrou maior espessura nos terços médio e caudal, com valores médios de 16,00mm e 19,85mm, respectivamente, contra 13,75mm e 14,99mm dos meniscos mediais. Os resultados deste estudo mostraram relação importante entre os dados morfométricos e os achados clínicos na tentativa de explicar a maior incidência de lesões envolvendo o menisco medial.(AU)

Meniscal lesions are one of the main causes of pain and lameness in horses. The objective of this study was to evaluate the morphometry of the meniscus of the femorotibial joint of horses. 48 meniscus were used from 12 animals, aged between five and 15 years and weighing between 400kg and 500kg. The measurement of the peripheral extension went from the most cranial part to the most caudal, denominated external circumference (CE). The internal margin, with the same treatment, was called internal circumference (IC). The meniscus was divided into cranial, middle and caudal thirds. The thickness was obtained at the midpoints of each third. The area of the meniscus in contact with the femoral condyles was also calculated. The medial meniscus presented a higher CE with a mean of 126.38mm, while the lateral meniscus presented a mean of 115.32mm. The lateral meniscus showed greater thickness in the middle and caudal thirds, with mean values of 16.00mm and 19.85mm respectively, against 13.75mm and 14.99mm of the medial meniscus. The results of this study showed an important relationship between the morphometric data and the clinical findings in an attempt to explain the higher incidence of lesions involving the medial meniscus.(AU)
