ABSTRACT

ABSTRACT Objective: There were many constraints produced by training time and joint injury to analyze the influence of the training intensity on the elbow and knee joints of athletes during the training process. Methods: An improved algorithm-based master component analysis (PCA) modeling method is proposed .1 4 4 athletes were selected in xxx and compared in three groups. Results: The improved PCA models for injury prediction were applied to athletes from group A, the traditional injury models for prediction were adopted for athletes from group B, and athletes from group C received the hospital physical examinations. The results showed that the accuracy of elbow injury in group A due to excessive exercise was 66.86%, the accuracy of hospital physical examination in group C was 67%, and the accuracy of the traditional algorithm in group B was 50%, finding that the accuracy of group A was obviously different from group B (P < 0.05). Compared with other injuries caused by excessive friction, the detection accuracy of knee injuries caused by excessive friction in group A was 62%, that in group B was 44%, and that in group C was 63%. There was a statistically marked difference between groups A and B (P < 0.05). Conclusions: A PCA - based model of athletes' overtraining injury has high accuracy and adaptability, predicting elbow injury. Level of evidence II; Therapeutic studies - investigation of treatment results.

ABSTRACT

Resumen: Introducción: la luxación traumática de la rodilla constituye una lesión rara dentro de la patología ortopédica. En muchas ocasiones su diagnóstico pasa desapercibido dado que se dan en el contexto de pacientes politraumatizados, y la falla en el mismo puede derivar en un pronóstico potencialmente letal para el compromiso vital del miembro lesionado. Objetivo: realizar una revisión de la literatura disponible en los últimos veinte años acerca de cuáles son las indicaciones del uso del fijador externo (FFEE) en la luxación traumática aguda de rodilla en la urgencia. Materiales y métodos: se realizó una búsqueda sistematizada a través de los buscadores electrónicos Cochrane, Lilacs, Scielo, Pubmed, Science direct y el portal Timbó. La misma alcanzó un total de 6.495 artículos, y de acuerdo con los criterios de inclusión y exclusión se seleccionaron 14 trabajos para realizarla. Resultados: se destaca que la mayoría de los artículos encontrados son de nivel de evidencia IV. La utilización del uso de la fijación externa en la urgencia como parte de la estabilización temporal y el manejo inicial estaría indicado en los siguientes escenarios clínicos: pacientes politraumatizados, lesión vascular, luxación expuesta, inestabilidad de la articulación, luxación recidivante, luxofracturas, lesiones a nivel del aparato extensor, obesidad mórbida, intolerancia del uso de la férula u ortesis. Conclusión: la sistematización y protocolización a la hora de la toma de decisiones permite disminuir de forma mayoritaria las complicaciones vinculadas a la patología traumática; éstas deben estar dirigidas a la estabilización del paciente en primera instancia, y en segunda instancia a estabilizar la articulación de la rodilla. La fijación externa tiene indicaciones en escenarios clínicos puntuales; sin embargo algunas de estas indicaciones aún son objeto de debate.


Abstract: Introduction: traumatic dislocation of the knee constitutes an unusual lesion in orthopedic pathology, the diagnosis of which is often missed. This is because it occurs in the context of multiple trauma patients, and failure to diagnose it may result in a potentially fatal outcome for the life-threatening compromise of the injured limb. Objective: to perform a literature review of literature on indications for the use of the external fixator in the acute knee dislocation at the emergency room that has been available in the last twenty years. Method: we conducted a systematized search by means of electronic search engines Cochrane, Lilacs, Scielo, Pubmed, Science direct and the Timbó portal. The search included 6495 articles and according to the criteria of inclusion and exclusion 14 studies were selected. Results: the review highlights that most articles found are level of evidence IV. The use of the external fixator in the emergency room as part of the temporary stabilization and initial handling of the condition would be indicated in the following clinical scenarios: multiple trauma patients, vascular lesion, exposed dislocation, joint instability, recurrent dislocation, fracture dislocation, lesions of the extensor apparatus, morbid obesity, splint or orthosis intolerance. Conclusion: systematization and the observation of protocols when it comes to the making of decisions enables the decrease of most complications associated to trauma pathologies. Actions must be geared to stabilizing patients first and to stabilize the knee joint. The external fixator is indicated for specific clinical scenarios. However, some of these indications are still a matter of debate.


Resumo: Introdução: a luxação traumática do joelho é uma lesão rara na patologia ortopédica. Em muitas ocasiões, seu diagnóstico passa despercebido, por ocorrer no contexto de pacientes politraumatizados, e que sua falha pode levar a um prognóstico potencialmente letal para o envolvimento vital do membro lesado. Objetivo: realizar uma revisão da literatura disponível nos últimos vinte anos sobre as indicações do uso do fixador externo na luxação traumática aguda do joelho em pronto-socorro. Materiais e métodos: foi realizada uma busca sistemática nas bases LILACS, SciELO, PubMed, Science Direct, na Biblioteca Cochrane e no portal Timbó. Foram obtidas 6.495 referencias dos quais 14 artigos foram selecionados de acordo com os critérios de inclusão e exclusão. Resultados: a maioria dos artigos encontrados apresentam evidência de nível IV. O uso de fixação externa na emergência como parte da estabilização temporária e manejo inicial, seria indicado nos seguintes cenários clínicos: pacientes politraumatizados, lesão vascular, luxação exposta, instabilidade articular, luxação recorrente, luxação, lesões ao nível do aparelho extensor, obesidade mórbida, intolerância ao uso de tala ou órtese. Conclusão: a sistematização e protocolização no momento da tomada de decisão é o que possibilita reduzir, em sua maioria, as complicações relacionadas à patologia traumática. Estas devem ter como objetivo em primeiro lugar estabilizar o paciente e, em segundo lugar, estabilizar a articulação do joelho. A fixação externa tem indicações em contextos clínicos específicos; no entanto, algumas delas ainda geram controvérsia.

ABSTRACT

ABSTRACT After arthroscopic ligament reconstruction, athletes still need to go through a postoperative rehabilitation training period and suffer the possible pain that can go from moderate to severe. Commonly used analgesic medications, ropivacaine and fentanyl have the effect of relieving athletes' pain. To study the analgesic effect of ropivacaine on arthroscopic reconstruction of the knee ligament, the steps of reconstruction and pharmacology of ropivacaine were first introduced. Next, the analgesic effects of ropivacaine and fentanyl in 86 athletes were compared on muscle strength recovery, patient satisfaction, and pain score. The results showed that the satisfaction of patients with ropivacaine was 95.35%, and the incidence of postoperative adverse reactions was only 9.30%. These results indicate that ropivacaine has a better analgesic effect in arthroscopic reconstruction of the knee ligament in athletes, which is suitable for postoperative rehabilitation.


RESUMO Após a reconstrução artroscópica do ligamento, os atletas ainda precisam passar por um longo período de treinamento pós-operatório de reabilitação e suportar a possível dor de moderada a severa. Os medicamentos analgésicos ropivacaina e fentanilo comumente utilizados têm o efeito de aliviar a dor dos atletas. Para estudar o efeito analgésico da ropivacaína na reconstrução artroscópica do ligamento do joelho foram introduzidos, em primeiro lugar, os passos da reconstrução artroscópica do ligamento e os da farmacologia da ropivacaína. Em seguida, os efeitos analgésicos da ropivacaína e o fentanilo em 86 atletas foram comparados com a recuperação na força muscular, na satisfação do paciente e na pontuação da dor. Os resultados mostraram que a satisfação dos doentes com a ropivacaína chegava a 95.35%, e a incidência de reações adversas pós-operatórias foi apenas de 9.30%. Estes resultados indicam que a ropivacaína tem melhor efeito analgésico na reconstrução artroscópica do ligamento do joelho, o que é adequado para a reabilitação pós-operatória.


RESUMEN Después de la reconstrucción artroscópica del ligamento, los atletas aun precisan pasar por un largo período de entrenamiento posoperatorio de rehabilitación y soportar el posible dolor que puede ir de moderado a severo. Los medicamentos analgésicos, ropivacaína y fentanilo que son comúnmente utilizados, tienen el efecto de aliviar el dolor de los atletas. Para estudiar el efecto analgésico de la ropivacaína en la reconstrucción artroscópica del ligamento de la rodilla fueron introducidos, en primer lugar, los pasos de la reconstrucción y de la farmacología de la ropivacaína.

ABSTRACT

Las fracturas osteocondrales (FOC) traumáticas de rodilla en la edad pediátrica, son lesiones que acompañan hasta un 30% de las luxaciones agudas de rótula (LAR). Si no se mantiene una elevada sospecha clínica, es frecuente su retraso diagnóstico, pudiendo generar potenciales complicaciones. A propósito, presentamos el caso de una paciente de 12 años con una FOC post LAR que pasó inadvertida en la primera consulta, requiriendo la fijación del fragmento osteocondral con tornillos HCS a los 5 meses, logrando un excelente resultado funcional a los 54 meses de seguimiento.


Traumatic osteochondral fractures (OCF) of the knee in pediatric age are injuries that accompany up to 30% of acute patellar dislocations (APD). If high clinical suspicion is not maintained, its diagnostic delay is frequent, and may generate potential complications. Incidentally, we present the case of a 12-year-old patient with a post-APD OCF that went unnoticed in the first consultation, requiring fixation of the osteochondral fragment with HCS screws at 5 months. Achieving an excellent functional result at 54 months follow-up.


As fraturas osteocondrais traumáticas (FOC) do joelho em idade pediátrica são lesões que acompanham até 30% das luxações agudas da patela (LAP). Se uma alta suspeita clínica não for mantida, seu atraso no diagnóstico é frequente e pode gerar complicações potenciais. A propósito, apresentamos o caso de um paciente de 12 anos com FOC pós-LAP que passou despercebido na primeira consulta, exigindo fixação do fragmento osteocondral com parafusos HCS em 5 meses. Obtendo um excelente resultado funcional aos 54 de acompanhamento.

ABSTRACT

Abstract Objective To evaluate clinically and radiologically the results of the treatment of chondral lesions using collagen membrane - autologous matrix-induced chondrogenesis (AMIC). Methods This is a series of observational cases, in which 15 patients undergoing AMIC were analyzed. The clinical evaluation was made by comparing the Lysholm and International Knee Document Commitee (IKDC) scores in the pre- and postoperative period of 12 months, and radiological evaluation using the Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) score in the same postoperative period. Results The mean age of the patients was 39.2 years old, and the mean size of the chondral lesions was 1.55cm2. There was a significant improvement in clinical scores, with a mean increase of 24.6 points on Lysholm and of 24.3 on IKDC after 12 months. In the radiological evaluation, MOCART had a mean of 65 points. It was observed that the larger the size of the lesion, the greater the improvement in scores. Conclusion Evaluating subjective clinical scores, the treatment of chondral lesions with the collagen membrane showed good results, as well as the evaluation of MOCART, with greater benefit in larger lesions.


Resumo Objetivo Avaliar clínica e radiologicamente os resultados do tratamento das lesões condrais com a membrana de colágeno - condrogênese autóloga induzida por matriz. Métodos Trata-se de uma série de casos observacional, na qual foram analisados 15 pacientes submetidos a condrogênese autóloga induzida por matriz. A avaliação clínica foi feita comparando os escores de Lysholm e International Knee Document Commitee (IKDC, na sigla em inglês) no pré- e pós-operatório de 12 meses, e avaliação radiológica através do escore de Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART, na sigla em inglês) no mesmo período de pós-operatório. Resultados A média de idade dos pacientes foi 39,2 anos, e a média do tamanho das lesões condrais foi de 1,55cm2. Houve uma melhora significativa nos escores clínicos, com média de aumento de 24,6 pontos no Lysholm e de 24,3 no IKDC, após 12 meses. Na avaliação radiológica, o MOCART teve média de 65 pontos. Observou-se que quanto maior o tamanho da lesão, maior foi a melhora nos escores. Conclusão Avaliando escores clínicos subjetivos, o tratamento das lesões condrais com a membrana de colágeno mostrou bons resultados, assim como a avaliação de MOCART, com maior benefício em lesões maiores.

ABSTRACT

Abstract Objective The main objective of the present study was to compare the subjective perception of pain and symptoms of anterior knee pain with the different body mass index (BMI) classifications. The secondary objective was to verify the association between biological and anthropometric variables with the results of subjective questionnaires. Methods A total of 126 recreational runners from both genders, aged between 20 and 59 years old, were recruited. Data regarding the biological variable (age), anthropometric variables (weight, height), visual analog scale (VAS), and Lysholm and Kujala questionnaires scores were collected. Information was obtained with a digital platform, available through a single link, allowing volunteers to answer these questions using electronic devices. Normality was verified by the Shapiro-Wilk test. T-tests and Wilcoxon tests were used to compare mean values. The association between variables was determined by the Pearson linear correlation. Results There were significant differences in height between overweight and grade 1 obesity subjects (p = 0.029), in weight and BMI comparing normal weight subjects and both overweight and grade 1 obesity subjects (p < 0.001 and p < 0.05, respectively). An unclear significant correlation was observed between BMI values and specific questionnaires and subjective scale scores (p < 0.05). Conclusion Recreational runners who present high BMI values are more likely to experience knee pain than those with normal BMI values.


Resumo Objetivo O principal objetivo do presente estudo foi comparar a percepção subjetiva de dor e sintomas de dor anterior no joelho com as diferentes classificações de índice de massa corporal (IMC). O objetivo secundário foi verificar a associação entre as variáveis biológica e antropométrica com os resultados apresentados pelos sujeitos nos questionários subjetivos. Métodos Foram recrutados 126 corredores recreacionais de ambos os gêneros, com idades entre 20 e 59 anos. Foram coletados dados referentes à variável biológica idade, e as variáveis antropométricas peso e altura, além da escala visual analógica (EVA) e os questionários Lysholm e Kujala. As informações foram obtidas por meio de plataforma digital, disponibilizado em um único link, para que fossem respondidos através de dispositivos eletrônicos pelos próprios voluntários. A normalidade foi verificada por meio do teste Shapiro-Wilk. Foi utilizado o teste-T e o teste de Wilcoxon para comparação das médias. A associação entre as variáveis foi determinada pela correlação linear de Pearson. Resultados Houve diferença significativa entre a estatura do grupo sobrepeso e o grupo obesidade grau 1 (p = 0,029), e o peso do grupo peso normal para os grupos sobrepeso e obesidade grau 1 (p < 0,001), e entre as médias do IMC (p < 0,05). Foi observada correlação significativa não clara entre o IMC e os questionários específicos e a escala subjetiva (p < 0.05). Conclusão Os corredores recreacionais que possuem IMC acima dos valores de normalidade estão mais predispostos a apresentar dor no joelho do que aqueles com IMC normal.

ABSTRACT

Abstract Objective The objective of the present study was to evaluate the relationship between patients with anterior cruciate ligament (ACL) injury by indirect trauma and increased posterior tibial inclination. Methods Retrospective study, performed by analysis of medical records and digital radiographs of patients, present in a database of a tertiary orthopedic hospital. The sample consisted of two groups, the first group consisting of patients diagnosed with ACL injury by indirect trauma, and a control group matched by age. Results Each group consisted of 275 patients, whose measurements of posterior tibial inclination were measured by three specialists. It was observed that the group of patients with ACL lesion presented a significantly higher tibial slope (in degrees) than the control group in the total sample and in the subsamples stratified by gender. The best cutoff point for the first group was identified as a posterior tibial inclination ≥ 8º, achieving a sensitivity of 63.3% and a specificity of 62.5%. The first group also had a tibial slope ratio ≥ 8º (63.3%), significantly higher than the control group (37.5%), with an odds ratio of 2.8. Conclusion It was concluded that the increase of the posterior tibial inclination is associated with an increased risk for injury of the ACL by indirect trauma, mainly for values ≥ 8º.


Resumo Objetivo O objetivo do presente estudo foi avaliar a relação entre pacientes com lesão do ligamento cruzado anterior (LCA) por trauma indireto e o aumento da inclinação posterior da tíbia. Métodos Estudo retrospectivo, realizado por análise de prontuários e radiografias digitais de pacientes, presentes em banco de dados de um hospital terciário de ortopedia e traumatologia. A amostra foi composta por dois grupos, sendo o primeiro formado por pacientes com diagnóstico de lesão do LCA, por trauma indireto, e um grupo controle pareado por idade. Resultados Cada grupo foi formado por 275 pacientes, cujas medidas de inclinação tibial posterior foram aferidas por 3 especialistas. Observou-se que o grupo dos pacientes com lesão do LCA apresentou slope tibial (em graus) significativamente maior que o grupo controle na amostra total e nas subamostras estratificadas por gênero. Identificou-se como o melhor ponto de corte (cutoff) para o primeiro grupo uma inclinação tibial posterior ≥ 8º, atingindo uma sensibilidade de 63,3% e uma especificidade de 62,5%. O primeiro grupo também apresentou proporção de slope tibial ≥ 8º (63,3%), significativamente maior que o grupo controle (37,5%), com razão de chances de 2,8. Conclusão Concluiu-se que o aumento da inclinação tibial posterior está associado com um maior risco para lesão do LCA por trauma indireto, principalmente para valores ≥ 8º,

Introducción: El objetivo del siguiente trabajo es mostrar los resultados de reparaciones meniscales en asa de balde con un seguimiento mínimo a dos años, describir la técnica quirúrgica utilizada y analizar los resultados funcionales, complicaciones y causas de falla. Materiales y métodos: evaluamos retrospectivamente pacientes intervenidos quirúrgicamente por nuestro equipo a los que se les realizó reparación de lesión en asa de balde meniscal, con cinco o más suturas, asociada, o no, a lesión del LCA. Se excluyeron los pacientes a los que se les realizaron cuatro o menos suturas y aquellos con cirugías previas y seguimiento menor a dos años. Resultados: cuarenta pacientes con edad promedio de veintiséis años (rango 8-60). Seguimiento promedio de cuarenta y ocho meses (rango 24-60). El promedio de suturas utilizadas fue de seis (rango 5-9 puntos). Cuatro pacientes presentaron fallas aisladas de la sutura meniscal por eventos traumáticos. Hasta la fecha, los pacientes con lesión asociada del LCA no presentaron fallas. Los scores de Lysholm, Tegner e IKDC mostraron gran mejoría en el postoperatorio. Conclusión: en la serie estudiada encontramos muy buenos resultados funcionales con la reparación meniscal, con un índice de falla del 10%. Es por esto que, para este tipo de lesiones, estimulamos al cirujano artroscopista a intentar la sutura meniscal por sobre la meniscectomía, aunque la primera sea, técnicamente, más demandante. Nivel de Evidencia: IV


Introduction: our aim is to show the results of bucket handle meniscal repairs with a minimum follow-up of two years, describing the surgical technique used and analyzing the functional results, complications and causes of failure. Materials and methods: we retrospectively reviewed those patients who were treated by our surgical team who experienced a bucket-handle meniscus tear that were isolated or with concomitant ACL injury. We excluded patients with four sutures or less, previous surgeries and follow up less than two years.Results: forty patients were included between 8 and 60 years old (average of 26 years). Average follow up of 48 months (range 24 to 60 months). The number of sutures varies from five up to nine (average: 6). Four patients (10%) were defined as failure, due to a new sport traumatic event. None of these had an ACL concomitant surgery. Lysholm, Tegner and IKDC post-operative score show promising results. Conclusions: we found encouraging outcomes and functional results with meniscal repair, with a failure rate of 10%. This is why, for this type of injury, we encourage the surgeon to always try meniscal repair over meniscectomy, although the former is technically more demanding. Level of Evidence: IV

ABSTRACT

Introducción: Las fracturas de la espina tibial son entidades con una baja incidencia, pero frecuentemente asociadas a lesiones concomitantes. La RM es el estudio considerado patrón de oro para estudiarlas y descartarlas.Presentación del caso: se presenta un caso de fractura de espina tibial desplazada y lesión en asa de balde concomitante. El tratamiento artroscópico de la lesión consistió en la fijación de la fractura de espina tibial con dos pines biodegradables y sutura meniscal interna con tres sistemas todo-adentro Meniscal Cinch® y dos puntos verticales fuera-dentro con FiberWire 2.0®. Conclusión: el paciente tuvo una excelente evolución clínica, sin presentar complicaciones inherentes a la lesión inicial ni al tratamiento implementado, con un retorno a sus actividades deportivas al mismo nivel previo a la lesión.Tipo de estudio: Reporte de caso.


Introduction: Tibial eminence fractures are uncommon injuries but are frequently associated to concomitant injuries. MRI is considered the Gold Standard; it allows a detailed evaluation of any soft tissue involvement with the injury. Case presentation: an unusual presentation case is reported: a displaced tibial spine fracture and a bucket handle medial meniscus injury. Arthroscopic reduction and fixation were performed, using two bioabsorbable pins for the tibial spine fixation; and three all-inside and two vertical outside-in sutures were needed for the medial meniscus repair. Conclusion: the patient presented excellent clinical outcomes, without presenting inherent complications due to primary injury nor realized treatment, achieving sport activity levels prior to injury. Type of study: Case report

ABSTRACT

Introducción: Las fracturas por avulsión del ligamento cruzado anterior (LCA) en adultos son inusuales y en general se deben a traumatismos de alta energía. Nuestro objetivo fue evaluar clínica y funcionalmente una serie de pacientes adultos con avulsión de espina tibial. Materiales y métodos: analizamos doce pacientes operados por avulsión de espina tibial entre diciembre de 2009 y diciembre de 2019 tratados con reducción y fijación artroscópica mediante suturas pull-out o tornillos canulados. Evaluamos el rango de movilidad articular (RMA) y la estabilidad postoperatoria con pruebas de Lachman, pivot shift y KT-1000, así como el retorno al deporte y resultados funcionales con las escalas de Lysholm e IKDC. Examinamos consolidación radiográfica y complicaciones postquirúrgicas. Resultados: ocho pacientes fueron incluidos. Cuatro tratados con tornillos canulados (grupo 1) y cuatro con suturas pull-out (grupo 2) con edad promedio de veintinueve años y seguimiento promedio de setenta y ocho y cuarenta y dos meses (grupos 1 y 2, respectivamente). Todos recuperaron el RMA, presentaron Lachman y pivot shift negativos y KT-1000 <3 mm. Tres de cinco pacientes retomaron deportes de pívot. Todos los pacientes presentaron consolidación radiográfica. No se registraron complicaciones postoperatorias.Conclusión: ambas técnicas quirúrgicas fueron efectivas para restablecer la estabilidad articular, lograr buenos resultados funcionales a corto y mediano plazo y alcanzar la consolidación radiográfica en los primeros tres meses postoperatorios


Introduction: Avulsion fractures of the anterior cruciate ligament (ACL) are rare in adults and generally due to high-energy trauma. The objective of this paper was to evaluate clinically and functionally a series of adult patients with anterior tibial eminence fractures treated with reduction and arthroscopic fixation using "pull-out" sutures or cannulated screws.Materials and methods: twelve patients operated on anterior tibial eminence fractures between December of 2009 and December of 2019 were analyzed in whom arthroscopic treatment was performed with "pull-out" sutures or cannulated screws. We evaluated the joint range of motion (ROM) and postoperative stability with Lachman, Pivot-Shift, and KT-1000 tests. Return to sport and functional results were evaluated with the Lysholm and IKDC scales. We analyzed radiographic consolidation and postsurgical complications. Results: eight patients were included. Four of them were treated with cannulated screws (group 1) and four with pull-out sutures (group 2) with a mean age of twenty-nine years and a mean follow-up of seventy-eight and forty-two months (groups 1 and 2, respectively). All of them recovered the ROM, presented negative Lachman and Pivot-Shift, and KT-1000 <3 mm at last follow-up. Three out of five patients returned to pivoting sports. The Lysholm average was 98.75 (group 1) and 91.25 (group 2). The IKDC average was 85.25 (group 1) and 74.67 (group 2). All patients presented radiographic consolidation. No postoperative complications were recorded.Conclusion: both surgical techniques were effective in restoring joint stability, achieving good functional results in the short and medium-term, and achieving radiographic consolidation in the first three postoperative months

ABSTRACT

Introducción: el propósito de este trabajo es hacer una evaluación retrospectiva clínica, funcional e imagenológica de una serie de pacientes con esqueleto inmaduro Tanner I y II intervenidos quirúrgicamente mediante la técnica de preservación fisaria de reconstrucción extra e intraarticular con autoinjerto de bandeleta iliotibial, técnica de Micheli. Evaluar si existieron alteraciones del crecimiento o angulares relacionadas con la cirugía. Materiales y métodos: se analizaron un total de veintidós rodillas en veinte pacientes con edad ósea promedio de 10.1 años y un seguimiento promedio de 5.6 años. Se realizó una evaluación clínica de movilidad, estabilidad incluyendo artrometría KT-1000, escalas funcionales y valoración por imágenes de discrepancia de longitud de miembros inferiores, alteraciones angulares y evaluación de integridad por resonancia magnética.Resultados: no hubo déficit de la movilidad con respecto a la rodilla contralateral, el test de Lachman, Pivot shift y la evaluación con KT-1000 fue normal en el 91, 95 y 95% de los pacientes, respectivamente. Se presentaron dos re-rupturas del injerto (9%). No hubo deformidades angulares del fémur o tibia ni discrepancia longitudinal de las extremidades inferiores. Las escalas funcionales mostraron un IKDC de 95.4 y un IKDC pediátrico de 92.3 en los pacientes a los que se les alcanzó a aplicar esta escala. Lysholm de 94.1 y un Tegner de 7 con un retorno al mismo deporte o actividad que causó la lesión del 90%. En la evaluación por resonancia magnética, el 100% de los pacientes que no presentaron re-ruptura tuvieron integridad del injerto. Conclusión: el procedimiento quirúrgico es seguro, reproducible, restaura la estabilidad anteroposterior y rotacional de la rodilla, sin causar alteraciones del crecimiento en este grupo poblacional, obteniendo excelentes puntajes en las escalas de valoración subjetivas, y un alto índice de retorno deportivo con un porcentaje menor de re-rupturas. Nivel de Evidencia: IV


Introduction: the purpose of this paper is to retrospectively evaluate clinical, functional and imagenological outcomes of a series of patients with skeletal immaturity Tanner 1 and 2, surgically intervened by physis preservation intra and extra articular reconstruction with iliotibial band autograft method described by Micheli. Evaluate growth or angular disturbances related to the surgical technique. Materials and methods: twenty-two knees in twenty patients with average bone age 10.1 years were evaluated with a 5.6 year follow up. Clinical evaluation of ROM and stability was made by arthrometry KT-1000, functional scales were applied, image evaluation of length discrepancy, angular deformity and integrity evaluation by magnetic resonance were also done. Results: no ROM deficit compared with the contralateral knee was observed, Lachman, Pivot shift tests and KT-1000 evaluation were normal in 91, 95 and 95% of patients, respectively. There were two cases of graft rupture (9%). No angular femoral or tibial deformities or length discrepancies were observed. Functional scales showed IKDC 95.4, pediatric IKDC 92.3 in patients who underwent the scale, Lysholm 94.1 and Tegner 7 with return to sports of 90% to pre level activity. 100% of patients without graft rupture had graft integrity in the RM evaluation. Conclusion: the surgical technique is safe and reproductible, restores anteroposterior and rotational stability of the knee without growth arrest in this population, obtaining excellent scores in subjective rating scales, high return to sports index with low rerupture rates.

ABSTRACT

Introducción: La lesión de LCA en niños con fisis abierta va en aumento debido a una mayor participación en deportes de contacto y al diagnóstico precoz. El tratamiento conservador de este tipo de lesiones está asociado al desarrollo de lesiones secundarias condrales y meniscales por lo que, sobre la base de la bibliografía actual, su tratamiento en pacientes esqueléticamente inmaduros con inestabilidad anterior de rodilla objetiva y sintomática es quirúrgico. Materiales y métodos: en el siguiente trabajo se presenta una revisión de dieciocho pacientes esqueléticamente inmaduros con reconstrucción de LCA y un seguimiento promedio de veintiséis meses (entre doce y cincuenta y seis) evaluados con los scores Lysholm, Tegner e IKDC, y telemetrías postoperatorias con mejoría de los scores funcionales permitiendo el retorno al mismo nivel de actividad deportiva en la mayoría de los casos. Conclusión: en esta población, no se han observado cambios en la angulación del miembro intervenido en las telemetrías postoperatorias de control, ni en el desarrollo de alteraciones del crecimiento. Tipo de estudio: Serie de Casos. Nivel de evidencia: IV


Introduction: ACL injury in children with open physis is increasing due to greater participation in contact sports and early diagnosis. Conservative treatment of this type of injury is associated with the development of secondary chondral and meniscal injuries, so based on current literature the treatment of this type of injury in skeletally immature patients with objective and symptomatic anterior knee instability is surgical. Materials and methods: the following work presents a review of eighteen skeletally immature patients with ACL reconstruction and an average follow-up of twenty-six months (between twelve and fifty-six months) evaluated with the Lysholm, Tegner and IKDC scores and postoperative telemetries with improvement in functional scores allowing return at the same level of sports activity in most cases. Conclusion: in this population, no changes in the angulation of the operated limb have been observed in the postoperative control telemetries or the development of growth alterations in any case. Type of study: Case series. Level of evidence: IV

ABSTRACT

O lipoma arborescente é uma causa incomum de lesão intra-articular que se apresenta como aumento de volume articular indolor, lentamente progressivo, que persiste por muitos anos e é acompanhado por derrames articulares intermitentes. O envolvimento de sítios extra-articulares é incomum, mas pode ocorrer em bainhas tendíneas e bursas. A ressonância magnética é o melhor exame para o diagnóstico, embora a biópsia sinovial possa ser necessária em alguns casos. Relatamos três casos com o objetivo de destacar o espectro clínico da doença, as características da imagem e a resposta ao tratamento imunossupressor.


Lipoma arborescens is an uncommon cause of intra-articular masses that presents as slowly progressive painless swelling of the joint, which persists for many years and is accompanied by intermittent effusions. Extra-articular site(s) involvement is unusual, but can occur in tendon sheaths and bursas. Magnetic resonance imaging is the best diagnostic exam, although synovial biopsy may be necessary. We report three cases in order to highlight the clinical spectrum and imaging features of the disease, so that early diagnosis and appropriate treatment can be given.

ABSTRACT

Introducción: Las lesiones meniscales horizontales tipo "cleavage" se extienden desde el margen interno libre del menisco, a través de la sustancia intrameniscal, hasta la unión menisco-capsular, y dividen el menisco en láminas superiores e inferiores. Se cree que son lesiones asociadas a meniscos degenerativos, por lo que tienden a ser más comunes en pacientes mayores. El tratamiento clásico consiste en realizar una meniscectomía parcial de la lámina superior o de la inferior, generando sobrecarga compartimental, la que puede desarrollar cambios degenerativos e inestabilidad. Actualmente, trabajos científicos nos presentan la posibilidad de reparar estas lesiones con diversas técnicas. El objetivo del siguiente trabajo es mostrar los resultados clínicos de una serie de pacientes tratados con reparación de las lesiones horizontales, los detalles de las técnicas utilizadas, índices de fallas y vuelta al deporte. Materiales y métodos: realizamos un estudio retrospectivo en el que analizamos una serie de veinticuatro pacientes con lesión meniscal horizontal tratados artroscópicamente con sutura entre 2014 y 2018 en el Hospital Universitario Austral y en el Sanatorio Mapaci. Evaluamos la cantidad y tipo de suturas meniscales, el dolor postoperatorio a través de la escala visual análoga (EVA), y la función con la escala de Lysholm e IKDC a los dos años de seguimiento. Evaluamos también el retorno al deporte y complicaciones.Resultados: la edad promedio fue de 27.8 años; ocho fueron mujeres y dieciséis, hombres. El menisco externo fue el más afectado con diecinueve casos y cinco fueron lesiones del menisco interno. En tres casos, cuando el menisco interno fue afectado, se realizó la técnica de "pie-crust" del ligamento colateral medial. Diez casos fueron asociados a reconstrucción del ligamento cruzado anterior. El promedio de cantidad de suturas meniscales fue de cuatro por paciente. El score de Lysholm a los dos años postoperatorio fue de 94, el IKDC postoperatorio de 88 y la escala EVA fue de 1/10. Todos los pacientes retornaron al deporte a los seis meses (casos aislados) y entre el noveno y el décimo mes (asociados a la reconstrucción del LCA).Conclusión: la reparación meniscal horizontal proporciona buenos resultados funcionales a mediano plazo al preservar la mayor cantidad de tejido meniscal. Creemos que es momento de un cambio de enfoque para este tipo de lesiones, la meniscectomía total o parcial no debería seguir siendo la "indicación de elección" en lesiones meniscales horizontales. En cambio, la preservación meniscal debería ser nuestro objetivo principal, siempre que sea posible. Nivel de Evidencia: IV


Introduction: Horizontal-cleavage meniscus tears begin at the inner edge of the meniscus and continue toward the capsule, dividing the meniscus in to a superior and inferior surface. They are typically associated to degenerative tears, therefore mainly affect elder people. Classically, treatment consisted of partial meniscectomy of either superior or inferior surface, resulting in a compartment overload and developing degenerative changes and instability. The latest publications shows that this type of tears can be repaired with several techniques. The aim of this study was to show the treatment for horizontal cleavage meniscus tears, by displaying a detailed evolution of the used techniques in a case series, evaluating results and outcomes, failure rate and return to sport.Materials and methods: twenty-four patients who underwent and arthroscopic repair of horizontal cleavage tears between 2014 and 2018 at Hospital Universitario Austral and Sanatorio Mapaci where retrospectively reviewed. We review the quantity and type of meniscal sutures, post-operative pain through Visual Analog Scale, Lysholm score and IKDC at two years follow-up. Also, we evaluated return to sports and complications.Results: the age average was of 27.8 years old. Eight patients where females and sixteen males. The most affected meniscus was the lateral in nineteen cases, and the medial in five. In three cases a medial collateral ligament (MCL) pie-crust technique was required when de medial meniscus was repaired. In ten cases a concomitant ACL reconstruction surgery was performed. The mean number of sutures per patient was four. Lysholm score at two years follow-up was of 94, IKDC of 88 and AVS of 1/10. The isolated cases returned to sports at six months after surgery, and the ones with ACL associated surgery between nine and ten months.Conclusion: by preserving more meniscal tissue, meniscal repair of horizontal-cleavage tears provides good functional outcomes at mid-term follow up. We believe that it is time for a change when approaching this type of injury, "treatment of choice" in horizontal cleavage injuries should not be partial or total meniscectomy. Instead, the main goal should be, whenever possible, meniscal tissue preservation. Level of Evidence: IV

ABSTRACT

Las lesiones de la raíz meniscal se definen como desgarros radiales ubicados dentro del centímetro de la inserción del menisco, o como una avulsión de la raíz ósea. Esta lesión es biomecánicamente comparable a una meniscectomía total, lo que lleva a una disminución del área de contacto tibiofemoral y un aumento perjudicial de las cargas para el cartílago articular y, en última instancia, conducen al desarrollo de una artrosis precoz.La reparación quirúrgica es el tratamiento de elección en pacientes sin artrosis significativa (grados 3 o 4 de Outerbridge). Las reparaciones de raíz mejoran los resultados clínicos, disminuyen la extrusión meniscal y enlentecen la aparición de cambios degenerativos. Aquí describimos la anatomía, biomecánica, evaluación clínica, métodos de tratamiento y resultados para los desgarros de las raíces meniscales posteriores. Nivel de Evidencia: IV


Meniscal root tears either are defined as an avulsion of the insertion of the meniscus attachment or complete radial tears that are located within 1 cm of the meniscus insertion. Untreated meniscal root tears have been reported to result in altered joint biomechanics and accelerated articular cartilage degeneration. In this regard, the "recently" recognized pathology of meniscal root tears have been reported to precipitously worsen articular cartilage degeneration, cause painful bone edema, and lead to progressive osteoarthritis if left untreated.Meniscal root repair has been demonstrated to have high satisfaction rates and superior outcomes than arthroscopic meniscectomy for root tears. Early referral of these patients for surgery had been demonstrated to significantly decrease the progression of knee osteoarthritis and the requirement for a TKA at mid-term follow-up.
