ABSTRACT

Abstract Objectives This study aims to analyze the safety of a simultaneous bilateral total knee arthroplasty (SBTKA) and to investigate patients' satisfaction with the procedure performed concomitantly. Methods In a prospective study, we evaluated 45 patients undergoing SBTKA performed by two surgical teams. The mean age of the patients was 66.9 years; 33 subjects were female (73.3%) and 12 (26.6%) were male. We followed a protocol of intra- and postoperatively measures to ensure the safety of this procedure. We evaluated the surgery time and blood loss by hematocrit (Ht) and hemoglobin (Hb) levels on the first postoperative day, the percentage of patients who received a transfusion of packed red blood cells, and the number of required units. We also recorded perioperative complications, and, at the end of 3 months, we asked patients about their preference between the simultaneous or staged procedure. Results The mean surgery time was 169 minutes. In the postoperative period, there was an average decrease of 28.2% in Htc and 27.0% in Hgb. A total of 16 patients (35.5%) received a transfusion of packed red blood cells (mean, 1.75 units per patient requiring a transfusion). There were 12 minor complications (26.6%) and 2 major complications (4.4%); furthermore, no patient had a clinical diagnosis of deep vein thrombosis, and there were no deaths. Conclusions The SBTKA procedure may be considered safe if performed in selected patients and with a care protocol to prevent complications. This type of procedure was unanimously approved by patients.


Resumo Objetivos Os objetivos deste estudo foram analisar a segurança da artroplastia total bilateral de joelho simultânea (ATJBS) e investigar a satisfação dos pacientes com o procedimento realizado de forma concomitante. Métodos Em um estudo prospectivo, avaliamos 45 pacientes submetidos à ATJBS feita por duas equipes cirúrgicas. A idade média dos pacientes foi 66,9 anos, sendo 33 do gênero feminino (73,3%) e 12 (26,6%) do gênero masculino. No período intra- e pós-operatório foi seguido um protocolo de medidas visando a segurança do procedimento. Avaliamos o tempo de cirurgia, a perda sanguínea pelo hematócrito (Ht) e hemoglobina (Hb), obtidos no primeiro dia de pós-operatório, a porcentagem de pacientes que receberam transfusão de concentrado de hemácias e quantidade de unidades que foram necessárias. Verificamosascomplicaçõesnoperíodo periopera-tório e, ao final de três meses, inquirimos aos pacientes sobre a preferência entre o procedimento simultâneo ou estagiado. Resultados O tempo médio de cirurgia foi de 169 minutos; no pós-operatório houve um decréscimo médio de 28,2% do Ht e de 27,0% da Hb. Ao todo, 16 pacientes (35,5%) receberam transfusão de concentrado de hemácias (média de 1,75 unidades por paciente que precisou de reposição). Tivemos 12 complicações menores (26,6%) e 2 complicações maiores (4,4%); além disso, nenhum paciente teve o diagnóstico clínico de trombose venosa profunda e não houve mortes. Conclusões A ATJBS pode ser considerada um procedimento seguro, se realizada em pacientes selecionados e com um protocolo de cuidados para prevenir complicações. Esse procedimento teve a aprovação unânime dos pacientes.

ABSTRACT

Abstract Objective This is the first study to establish the utility of extended curettage with or without bone allograft for Grade II giant cell tumors GCTs around the knee joint with the aim of exploring postoperative functional outcomes. Methods We retrospectively reviewed 25 cases of Campanacci grade II GCTs undergoing extended curettage between January 2014 and December 2019. The participants were divided into two groups: one group of 12 patients underwent extended curettage with bone allograft and bone cement, while the other group of 13 patients underwent extended curettage with bone cement only. Quality of life was assessed by the Revised Musculoskeletal Tumor Society Score and by the Knee score of the Knee Society; recurrence and complications were assessed for each cohort at the last follow-up. The Fisher test and two-sample t-tests were used to compare the categorical and continuous outcomes, respectively. Results The mean age was 28.09 (7.44) years old, with 10 (40%) males and 15 females (60%). The distal femur and the proximal tibia were involved in 13 (52%) and in 12 (48%) patients, respectively. There was no significant difference in the musculoskeletal tumor society score (25.75 versus 27.41; p= 0.178), in the knee society score (78.67 versus 81.46; p= 0.33), recurrence (0 versus 0%; p= 1), and complications (25 versus 7.69%; p= 0.21). Conclusions Extended curettage with or without bone allograft have similar functional outcomes for the knee without any major difference in the incidence of recurrence and of complications for Grade II GCTs. However, surgical convenience and cost-effectiveness might favor the bone cement only, while long-term osteoarthritis prevention needs to be investigated to favor bone allograft.


Resumo Objetivo Este é o primeiro estudo a estabelecer a utilidade da curetagem estendida com ou sem enxerto ósseo em tumores de células gigantes (TCGs) de grau II na articulação do joelho com o objetivo de explorar os resultados funcionais pós-operatórios. Métodos Revisamos retrospectivamente 25 casos de TCGs de grau II de Campanacci submetidos a curetagem estendida entre janeiro de 2014 e dezembro de 2019. Os participantes foram divididos em 2 grupos: um grupo de 12 pacientes foi submetido a curetagem estendida com aloenxerto ósseo e cimento ósseo, enquanto o outro grupo, com 13 pacientes, foi submetido a curetagem estendida apenas com cimento ósseo. A qualidade de vida foi avaliada pela Pontuação Revista da Musculoskeletal Tumor Society (MTS, na sigla em inglês) e pela Pontuação da Knee Society (KS, na sigla em inglês), enquanto as taxas de recidiva e complicações foram avaliadas em cada coorte na última consulta de acompanhamento. O teste de Fisher e os testes t de duas amostras foram usados para comparação de resultados categóricos e contínuos, respectivamente Resultados A média de idade dos pacientes foi de 28,09 (7,44) anos; 10 (40%) pacientes eram do sexo masculino e 15 (60%) pacientes eram do sexo feminino. O fêmur distal e a tíbia proximal foram acometidos em 13 (52%) e 12 (48%) dos pacientes, respectivamente. Não houve diferença significativa na pontuação revista da MTS (25,75 versus 27,41; p= 0,178), na pontuação da KS (78,67 versus 81,46; p= 0,33) e nas taxas de recidiva (0 versus 0%; p= 1) e complicações (25 versus 7,69%; p= 0,21). Conclusões A curetagem estendida com ou sem aloenxerto ósseo tem resultados funcionais semelhantes em pacientes com TCGs de grau II no joelho, sem qualquer diferença importante na incidência de recidivas e complicações. No entanto, a conveniência cirúrgica e o custo-benefício podem favorecer a utilização apenas de cimento ósseo, enquanto a prevenção da osteoartrite em longo prazo precisa ser investigada para favorecer o enxerto ósseo.

ABSTRACT

Descripta por Ahlbäck en 1968, la osteonecrosis de rodilla es una patología con un gran potencial de morbilidad. Está dividida en tres grandes grupos: primaria/espontánea, postoperatoria y secundaria/atraumática. Esta última podría estar directamente relacionada con el consumo prolongado de corticoides. Su tratamiento constituye un desafío para el cirujano ortopedista. Va a depender del estadio de la enfermedad y del colapso articular, y se intentará siempre preservar la superficie articular nativa. Dentro de las distintas opciones terapéuticas, las terapias biológicas constituyen una herramienta potencialmente valiosa como complemento al tratamiento quirúrgico, y muestran resultados clínicos esperanzadores. Presentamos el caso de una paciente con una osteonecrosis de rodilla bilateral, secundaria al consumo crónico de corticoides, tratada con una artroscopía bilateral asociada a perforaciones subcondrales descompresivas y aplicación subcondral de concentrado de médula ósea (CMO), con evolución satisfactoria de los síntomas a los treinta meses de seguimiento en la rodilla derecha, mientras que en la rodilla izquierda presentó una evolución tórpida de los síntomas a partir de los veinticuatro meses, por lo que está en plan de reemplazo articular.


Described by Ahlbäck in 1968, osteonecrosis of the knee is a pathology with great potential for morbidity. It is divided into three large groups: primary/spontaneous, postoperative, and secondary/atraumatic. The latter might be directly related to prolonged consumption of steroids. Its treatment is a challenge for the orthopedist. It will depend on the disease stage and articular collapse, always trying to preserve the native articular surface. Within the different therapeutic options, biological therapies are a potentially valuable tool as a complement to surgical treatment, showing encouraging clinical results. We present the case of a female patient with bilateral osteonecrosis of the knee, secondary to chronic consumption of steroids, treated with bilateral arthroscopy associated with decompressive subchondral perforations and subchondral application of bone marrow concentrate (BMC), with a satisfactory evolution of symptoms after thirty months of follow-up in the right knee. However, the left knee showed a torpid evolution of symptoms after twenty-four months of follow-up, so she is on a joint replacement plan

ABSTRACT

El tumor glómico es una neoplasia benigna poco común que surge del aparato glómico de la piel. Ocurre con mayor frecuencia en los dedos de manos y pies y representa el 1.6% de todos los tumores de tejidos blandos. El diagnóstico clínico puede resultar difícil si el tumor aparece en una ubicación extradigital. Presentamos un caso de tumor glómico de tipo vascular (glomangioma) de localización atípica, suprapatelar externa y de presentación inusual ya que no evidenciaba cambios de color en la superficie, indicando su componente vascular


Glomus tumor are rare benign tumor of the glomus body from the skin. Often occurring in the subungual region and it represents 1.6% of all soft tissue tumors. Clinical diagnosis may result difficult if the tumor occurs in an extra digital location.We report a case of a solitary vascular Glomus Tumor (Glomangioma) with an atypical localization, suprapatellar external and unusual presentation because it did not present with surface color change, indicating the vascular component

ABSTRACT

El schwannoma es el tumor benigno de nervio periférico más frecuente. Su presencia en los nervios de miembros inferiores es excepcional, donde representan el 1% de todos los schwannomas. Presentamos el caso de una mujer de treinta y un años que consulta por dolor en la cara anterior de la rodilla derecha, donde se palpa una masa blanda, dolorosa, de 1 cm aproximadamente y dolor en interlínea externa con signo de McMurray positivo. La RM evidenció una estructura ovoidea de señal quística, superficial al retináculo medial en su tercio proximal, de 10 × 8 × 8 mm y lesión del menisco externo en su tercio medio. Se realizó tratamiento artroscópico de la lesión meniscal externa y por vía abierta la exéresis marginal quirúrgica del tumor de partes blandas, con diagnóstico histopatológico de schwannoma. Los schwannomas de nervio periférico, aunque sean una entidad poco frecuente, deben considerarse en el diagnóstico diferencial de las masas dolorosas de la rodilla. Su tratamiento es la exéresis quirúrgica


Schwannoma is the most common benign peripheral nerve tumor, its presence being exceptional in the nerves of the lower limbs, where it represents 1% of all schwannomas. We present the case of a thirty-one-year-old woman who consulted for anterior knee pain, where a soft, painful mass of approximately 1cm and pain on the lateral joint line was assessed. McMurray's sign was positive. MRI showed an ovoid structure with a cystic signal, superficial and proximal to the medial retinaculum, measuring 10 × 8 × 8 mm and a tear in the body and posterior horn of the lateral meniscus. Arthroscopic treatment for the lateral meniscus tear and open surgical marginal excision of the soft tissue tumor were performed, with pathological diagnosis of schwannoma. Peripheral nerve schwannomas, although a rare entity, should be considered in the differential diagnosis of painful knee masses, their treatment being surgical excision

ABSTRACT

Relata-se o caso de uma felina, sem raça definida, de oito meses de idade e 3,6 kg, com queixa de impotência funcional completa do membro pélvico esquerdo após trauma. A paciente apresentava aumento de volume em região do joelho, dor à palpação e instabilidade patelar. O diagnóstico de ruptura do ligamento patelar foi realizado com base nos resultados do exame ortopédico, juntamente com exame radiográfico e ultrassonográfico do joelho. O método utilizado para reparo da lesão foi a sutura em oito com fio de tetrafluorcabono associado à sutura interrompida simples para aproximação das bordas do ligamento. Durante a reavaliação de trinta dias pós-operatório, a paciente já apresentava melhora significativa, com atividade funcional completa do membro e ausência de dor.


We report the case of an eight-month-old, 3.6 kg, crossbred feline, complaining of complete functional impotence of the left pelvic limb after trauma. The patient presented swelling in the knee region, pain on palpation and patellar instability. The diagnosis of patellar ligament rupture was based on the results of the orthopedic examination, together with radiographic and ultrasound examinations of the knee. The method used to repair the lesion was eight-point suture with tetrafluorocabono thread associated with simple interrupted suture for approximation of the ligament edges. During the thirty-day postoperative reassessment, the patient already presented significant improvement, with complete functional activity of the limb. and absence of pain.

ABSTRACT

Abstract Objective To describe the treatment provided by specialists for ACL lesions in professional soccer players. Methods A cross-sectional study in which orthopedic surgeons affiliated to soccer teams competing in the Brazilian Soccer Championship answered a questionnaire about the treatment of ACL injuries in professional soccer players. Results The specialists wait between one to four weeks after the ACL injury to perform the surgical treatment. They use a single incision and single-bundle reconstruction, assisted by arthroscopy, femoral tunnel drilling by an accessory medial portal, and quadruple flexor tendon autografts or patellar tendon autografts. After three to four months, the players are allowed to run in a straight line; after four to six months, they begin to practice exercises with the ball without contact with other athletes; and, after six to eight months, they return to play. The main parameter used to determine the return to play is the isokinetic strength test. The specialists estimate that more than 90% of elite soccer players return to playing professionally after an ACL reconstruction, and 60 to 90% return to play at their prior or at a greater level of performance. Conclusion The present article successfully describes the main surgical practices and post-surgery management adopted by specialists in this highly-specific population of patients.


Resumo Objetivo Descrever o tratamento realizado por especialistas das lesões do ligamento cruzado anterior (LCA) em jogadores profissionais de futebol. Métodos Estudo transversal, no qual ortopedistas vinculados a clubes participantes do Campeonato Brasileiro de Futebol responderam a um questionário sobre o tratamento das lesões do LCA em jogadores profissionais de futebol. Resultados Os especialistas aguardam entre uma e quatro semanas após a lesão do LCA para realizar o tratamento cirúrgico. Utilizam técnica com incisão e banda únicas auxiliada por artroscopia, perfuração do túnel femoral via portal acessório medial, e autoenxerto quádruplo de tendões flexores ou autoenxerto de tendão patelar. Os jogadores são liberados para correr em linha reta após três a quatro meses; para exercícios com bola sem contato com outros atletas, após quatro a seis meses; e o retorno ao esporte acorre após seis a oito meses. O principal parâmetro usado para o retorno ao esporte é o teste de força isocinético. Os especialistas estimam que mais de 90% dos jogadores operados por lesão do LCA retornam ao esporte profissional, e entre 60% e 90% retornam com o mesmo nível ou com um nível melhor de desempenho. Conclusão Este estudo descreve de forma satisfatória as principais práticas cirúrgicas e pós-operatórias adotadas pelos especialistas nessa população altamente específica de pacientes.

ABSTRACT

Abstract Bilateral atraumatic rupture of the patellar ligament is a rare lesion, usually associated with systemic diseases and drugs such as steroids and fluoroquinolones. This report presents a case of bilateral atraumatic rupture of the patellar ligament in a 43-year-old male with obesity, type 2 diabetesmellitus, and who was being treated with a systemic corticosteroid for autoimmune disease (Wegener granulomatosis). These factors caused chronic degenerative and inflammatory changes in the ligaments, confirmed by the histological examination. Due to tissue quality, a primary ligament repair associated to an augmentation with semitendinosus tendon was performed. After 1 year, the patient presented satisfactory evolution, regaining the full range of motion and returning to his usual activities without sequelae.


Resumo A ruptura atraumática bilateral do ligamento patelar é uma lesão rara, geralmente associada a doenças sistêmicas e ao uso de medicamentos como corticoides e fluoroquinolonas. Este relato apresenta um caso de rotura atraumática bilateral do ligamento patelar em umhomem de 43 anos, portador de obesidade, diabetesmelitus tipo 2 e em uso de corticoide sistêmico para doença autoimune (granulomatose de Wegener). Esses fatores provocam alterações degenerativas e inflamatórias crônicas nos ligamentos, confirmadas pelo exame histológico. Devido à qualidade tecidual, foi feito reparo primário do ligamento associado a reforço com o tendão semitendíneo. Após um ano, o paciente apresentou evolução satisfatória, comganho de amplitude de movimento completo e retorno às atividades habituais, sem sequelas.

ABSTRACT

RESUMEN Introducción: en el diagnóstico y tratamiento del genu varo doloroso es importante el estudio radiográfico de la rodilla, se pueden visualizar los cambios estructurales que aparecen en las superficies articulares de la rodilla. Objetivo: demostrar desde el punto de vista radiológico la variación que ocurre posterior a la ostectomía del peroné en los pacientes operados de genus varos. Materiales y métodos: se realiza un estudio descriptivo, prospectivo y lineal en el Hospital Militar Dr. Mario Muñoz Monroy de Matanzas desde abril del 2016 -2017 donde se aplica la técnica de ostectomía del peroné, del Dr. Zhang Ying-Ze, se presentan los primeros 51 pacientes operados, un total de 57 rodillas, a los cuales se les realizó radiografía previa a la operación y posterior a ella al cabo de los 6 meses, donde se midió la altura del espacio articular externo. Resultados: el promedio de edad es de 67,2 años (50 años el menor y 84 años el mayor), de los cuales 23 eran hombres y 28 mujeres, previo al tratamiento quirúrgico el promedio de este espacio fue de 8,84 mm±1,01 mm (18 mm el mayor y el menor 2 mm) y al cabo de los 6 meses fue de 6,08 mm±0,9 mm(el mayor 10 mm y el menor 2 mm), en 6 pacientes no hubo variación de esta medida. Conclusiones: con la ostectomía proximal del peroné se logra disminuir el espacio articular externo modificando el eje mecánico y anatómico del miembro inferior, lo que se traduce por una disminución de la compresión interna articular (AU).


ABSTRACT Background: the radiographic study of the knee is very important in the painful genu varum diagnosis and treatment: structural changes appearing in the knee joint surfaces may be observed. Objective: to show the changes taking place after fibular ostectomy in the patients surgically treated of genu varum from the radiological point of view. Material and methods: a lineal, prospective, descriptive study was carried out in the Military Hospital "Dr. Mario Muñoz Monroy" of Matanzas from April 2016 to April 2017, in 51 patients operated on applying Dr Zhang Ying-Ze's fibular ostectomy technique: a total of 57 knees. X-rays were taken before the surgery and six months after it, measuring the height of the external intra joint space. Results: the average age was 67.2 years (50 years the youngest and 84 the eldest patients); 23 were men and 28 women. Before the surgical treatment the average space was 8.84 mm±1.01 mm (18 mm the biggest and 2 mm the smallest); six months after surgery, it was 6.08 mm±0.9 mm (10 mm the biggest and 2 mm the smallest); six patients did not showed changes of the space. Conclusions: with the proximal fibular ostectomy we achieved the reduction of the external fibular space, modifying the anatomical and mechanical axis of the lower limb, what leads to a reduction of the internal joint compression (AU).

ABSTRACT

INTRODUCCIÓN: Desde que se implantó la primera prótesis total de rodilla en nuestro medio, se advierte que la mayor parte de las personas acuden a cirugía, no solo cuando el dolor se torna insoportable, sino cuando también la deformidad se ha instaurado o aumentó considerablemente y la función se ve disminuida. OBJETIVO: Determinar los resultados funcionales y las complicaciones de la artroplastía total de rodilla en el servicio de Traumatología y Ortopedia del Hospital Obrero N° 1 durante el periodo 2010 ­ 2015. MATERIAL Y MÉTODOS: Estudio serie de casos. Se estudiaron 121 pacientes de ambos sexos, con diagnóstico de gonartrosis primaria o secundaria, internados en el servicio de Traumatología y Ortopedia del Hospital Obrero Nº 1, durante el periodo del 1° de enero del 2010 al 31 de diciembre del año 2015. La valoración funcional se calificó mediante el cuestionario WOMAC y las complicaciones mediante registro de expedientes clínicos. RESULTADOS: El sexo más afectado es el femenino (75.79%), la edad más frecuente oscila entre 60 y 69 años (50.41%), la comorbilidad preoperatoria más frecuente en los pacientes operados es la artritis reumatoide (33.88%), los resultados funcionales post-operatorios del reemplazo articular son en su mayoría buenos (75.21%), la complicación post-operatoria más frecuente, fue la infección en un 9.09%, la cantidad de días de internación post-operatorio promedio es de 7.2 días. CONCLUSIÓN: Se observaron resultados funcionales Buenos (escala WOMAC) y la infección como la complicación más frecuente en los sujetos de nuestro estudio.


INTRODUCTION: Since the first full knee prosthetics was implanted in our city, it is noticed that most people attend surgery, not only when the pain becomes unbearable, but when deformity has also established itself or it increased considerably and the function looks diminished. OBJECTIVE: Determining the functional results and the complications of the total arthroplasty of knee at the service of Traumatología y Ortopedia of the Hospital Obrero N° 1 during the period 2010 ­ 2015. MATERIAL AND METHODS: Case series study. 121 patients of both sexes were studied, with diagnosis of gonarthrosis primary or secondary in the service of Traumatología y Ortopedia of the Hospital Obrero N° 1, from January 1, 2010 to December 31, 2015. The functional assessment was graded by means of the questionnaire WOMAC and the complications by means of clinical records. RESULTS: The most affected sex is the feminine (75,79 %), the most frequent age oscillates between 60 and 69 years (50,41 %), the most frequent preoperative comorbidity in the operated patients is rheumatoid arthritis (33,88 %), the functional post-operative results of the joint replacement are mainly good (75,21 %), the most frequent post-operative complication, was the infection in a 9,09 %, The amount of days of post-operative hospitalization average is 7,2 days.

ABSTRACT

OBJETIVO: Presentar un caso de complicación de fractura de platillos tibiales Schatzker VI y su manejo quirúrgico. MATERIAL Y MÉTODO: Se presenta un caso de fractura de platillos tibial Schatzker VI que evoluciona con malalineamiento en valgo secundario a hundimiento del platillo tibial, junto a una revisión de la literatura y la descripción del manejo quirúrgico. RESULTADOS: Se realizó una osteotomía en cuña de cierre medial de tibia proximal y se estabilizó con placa bloqueada (TomoFix), con una corrección completa de la deformidad sin complicaciones. Discusión: La osteotomía en cuña de cierre medial en tibia proximal es una técnica descrita en el manejo de artrosis secundaria a malalineamiento en valgo de la rodilla. Mediante dos osteotomías iniciadas por la cortical medial hacia la lateral con un fulcro esa última, se retira una cuña de dimensiones conocidas y se mantiene la reducción con algún elemento de osteosíntesis. De esa forma, se permite la corrección angular de la deformidad, previamente planificada. Los resultados en distintas series son en general favorables. CONCLUSIÓN: El malalineamiento de la extremidad posterior a una fractura de platillos tibiales y la consecuente sobrecarga del compartimento afectado en la rodilla, asociado al daño articular, evoluciona con degeneración articular que termina en una artrosis unicompartimental secundaria, la cual puede ser prevenida con el uso de osteotomías correctoras de ejes como la osteotomía de tibia proximal, permitiendo normalizar la distribución de las cargas en los compartimentos mediante la corrección del eje mecánico alterado y así prolongar la sobrevida articular.


OBJECTIVE: To present a Schatzker VI tibial plateau fracture case complication and its surgical management METHODS: We present a case of tibial plateau fracture, type VI according to Schatzkeŕs classification, that developed limb malalignment secondary to tibial plateau depression resulting in a genu valgum deformity, along with a literature review and a brief description of the surgical technique. Results: High tibial medial closing wedge osteotomy, stabilized with locking plate (tomoFix) was performed, with a complete correction of the deformity without complications. DISCUSSION: High tibial medial closing wedge is a known procedure used in the management of valgus knee malalignment secondary osteoarthritis. By means of two osteotomies made from medial to lateral cortices, using the latter as a fulcrum, a wedge with known dimensions is subtracted and reduction is maintained with some osteosynthesis element. In this fashion, it allows the previously planned angular correction. Results in different reports are mostly favorable. CONCLUSION: The malalignment of the limb after a tibial plateau fracture and the consequent overload of the affected knee compartment; associated with joint damage, evolves in joint degeneration and eventually, in a secondary unicompartmental osteoarthritis. This can be avoided with the use of corrective osteotomies such as the proximal tibial osteotomy, which allows a proper distribution of loads in the compartments by correcting the altered mechanical axis and thus, prolonging joint survival.

ABSTRACT

Introducción: el bloqueo del nervio femoral es una de las técnicas básicas del bloqueo nervioso. Objetivo: describir los resultados del bloqueo del nervio femoral con estimulador de nervio periférico en pacientes intervenidos de artroscopia de rodilla. Método: estudio observacional, descriptivo, prospectivo de corte longitudinal. La muestra estuvo integrada por 84 pacientes intervenidos de artroscopia de rodilla en los cuales se utilizó el bloqueo del nervio femoral como técnica anestésica. Se incluyeron pacientes mayores de 18 años, con estado físico I-III según la Sociedad Americana de Anestesiología (ASA), sin alergia conocida a los anestésicos locales y sin contraindicaciones para las técnicas regionales; se excluyeron del estudio aquellos pacientes con intervención quirúrgica ilioinguinal previa, con tumoraciones en región inguinal o neuropatía femoral. Resultados: la calidad del bloqueo fue buena en 90,5 por ciento, de los pacientes, regular en 7,1 por ciento y mala en el 2,4 por ciento. La media del tiempo de analgesia al movimiento fue de 15,17 h (DE 10,52), con un mínimo de 4,17 y un máximo de 28,40 h. Las complicaciones fueron escasas (9,52 por ciento). La más frecuente resultó la parestesia y el bloqueo insatisfactorio en 4,8 y 2,4 por ciento respectivamente. El grado de pacientes satisfechos fue el 95,2 por ciento del total. Conclusiones: el tiempo de analgesia en más de la mitad de los pacientes fue mayor de 12 h y la intensidad del dolor en el rango de dolor leve-moderado, tanto en reposo como al realizar algún movimiento. Las complicaciones fueron escasas, la más frecuente fue la parestesia. La técnica se asocia con elevados niveles de satisfacción por parte de los pacientes(AU)


Introduction: The femoral nerve block is one of the basic nerve block techniques. Objective: To describe the results of femoral nerve block with peripheral nerve stimulator in patients undergoing knee arthroscopy. Method: Observational, descriptive, prospective and longitudinal study. The sample consisted of 84 patients undergoing knee arthroscopy, in whom femoral nerve block was used as an anesthetic technique. Patients older than 18 years were included, with physical status I-III according to the American Society of Anesthesiology (ASA), without known allergy to local anesthetics and without contraindications for regional techniques; patients with previous ilioinguinal surgery, and with tumors in the inguinal region or femoral neuropathy, were excluded from the study. Results: The block quality was good in 90.5 percent of the patients, regular in 7.1 percent, and poor in 2.4 percent. The average time of analgesia to movement was 15.17 hours (SD 10.52), with a minimum of 4.17 and a maximum of 28.40 hours. Complications were minimal (9.52 percent). The most frequent was paresthesia and the unsatisfactory block, in 4.8 and 2.4 percent, respectively. The degree of satisfied patients was 95.2 percent of the total. Conclusions: The analgesic time in more than half of the patients was greater than 12 hours, while the pain intensity was in the range of mild to moderate, both at rest and when performing some movement. Complications were minimal, the most frequent was paresthesia. The technique is associated with high levels of satisfaction as expressed by the patients(AU)

ABSTRACT

ABSTRACT OBJECTIVE: To present the outcomes of posterior cruciate ligament (PCL) double-bundle reconstruction using autologous hamstring tendons, with a minimum follow-up of two years. METHODS: Evaluation of 16 cases of PCL injury that underwent double-bundle reconstruction with autogenous hamstring tendons, between 2011 and 2013. The final sample consisted of 16 patients, 15 men and one woman, with a mean age of 31 years (21-49). The predominant mechanism was motorcycle accident in half of the cases. There was a mean interval of 15 months between the time of lesion and the surgery (three to 52 months). Five lesions were isolated and 11, associated. Clinical evaluation, application of validated scores, and measurements with use of the KT-1000 were performed. RESULTS: The analysis showed a mean preoperative Lysholm score of 50 points (28-87), progressing to 94 points (85-100) postoperatively. The IKDC score also demonstrated improvement. In the preoperative evaluation, four and 12 patients were respectively classified as C (abnormal) and D (very unusual), and in the postoperative evaluation six as A (normal) and ten as B (close to normal). In the post-operative evaluation by KT1000 arthrometer, 13 patients showed difference between 0-2 mm and 3 between 3 and 5 mm, when compared with the contralateral side. CONCLUSION: Autologous hamstring tendons are a viable option in double-bundle reconstruction of the PCL, with good clinical results in a minimum follow-up of two years.

MÉTODO: Avaliação de 16 casos de lesão do LCP submetidos a reconstrução em dupla banda com tendões flexores autólogos entre 2011 e 2013. A amostra final foi composta por 16 pacientes, 15 homens e uma mulher, com média de 31 anos (21-49). O mecanismo predominante foi acidente motociclístico em metade dos casos. Houve um intervalo médio de 15 meses entre a lesão e a cirurgia (três a 52 meses). Cinco lesões eram isoladas e 11, associadas. Foram feitas avaliação clínica, aplicação de escores validados e mensuração com uso do artrômetro KT-1000. RESULTADOS: A avaliação pela escala de Lysholm pré-operatória teve média de 55 pontos (28-87), evoluiu para uma média pós-operatória de 94 pontos (85-100). O IKDC também demonstrou melhoria. Na avaliação pré-operatória, quatro e 12 pacientes foram respectivamente classificados como C (anormal) e D (muito anormal); na avaliação pós-operatória, seis foram classificados como A (normal) e dez como B (próximo ao normal). Na avaliação pós-operatória pelo artrômetro KT1000, 13 pacientes apresentaram diferença entre 0-2 mm e três, entre 3-5 mm, na comparação com o lado contralateral. CONCLUSÃO: O uso dos tendões flexores autólogos é uma opção viável na reconstrução do LCP em dupla banda, apresenta bons resultados clínicos em seguimento mínimo de dois anos.

ABSTRACT

ABSTRACT OBJECTIVE: To compare the clinical and radiological outcomes of conventional medial and lateral approaches for total knee replacement in the valgus osteoarthritic knee. METHODS: In this randomized controlled trial, 21 patients with valgus knee osteoarthritis were randomized to total knee replacement through medial or lateral approach. The primary outcome was radiographic patellar tilt. Secondary outcomes were visual analog scale of pain, postoperative levels of hemoglobin, and clinical aspect of the operative wound. RESULTS: There were no differences between the groups regarding other clinical variables. Mean lateral tilt of the patella was 3.1 degrees (SD ± 5.3) in the lateral approach group and 18 degrees (SD ± 10.2) in the medial approach group (p = 0.02). There were no differences regarding the secondary outcomes. CONCLUSION: Lateral approach provided better patellar tilt following total knee replacement in valgus osteoarthritic knee.


RESUMO OBJETIVO: Comparar os resultados clínicos e radiológicos da via de acesso convencional com artrotomia medial e da via de acesso lateral na prótese total primária em joelho valgo. MÉTODOS: Neste ensaio clínico prospectivo, 21 pacientes com osteoartrite e deformidade em valgo foram divididos aleatoriamente em dois grupos de acordo com a via de acesso cirúrgico usada: medial ou lateral. O desfecho principal foi a medida radiográfica da inclinação lateral da patela. Outros desfechos foram a dor após a cirurgia (escala visual de dor), o sangramento (níveis séricos de hemoglobina) e o aspecto clínico da ferida operatória. RESULTADOS: Não houve diferença entre os grupos em relação a outras variáveis clínicas. A inclinação lateral média da patela no grupo lateral foi 3,1 graus ± 5,3 DP e no grupo medial foi 18 graus ± 10,2 DP (p = 0,02). Os outros desfechos não apresentaram diferenças entre os grupos. CONCLUSÃO: A via lateral proveu melhor inclinação lateral da patela pós-operatória nas artroplastias do joelho valgo.

ABSTRACT

OBJECTIVE: To compare the transtibial and two-incision techniques for anterior cruciate ligament (ACL) reconstruction using a single band. METHODS: A prospective and randomized study was conducted in blocks. Patients underwent ACL reconstruction by means of two techniques: transtibial (group 1: 20 patients) or two incisions (group 2: 20 patients). The radiographic positioning of the tunnel, inclination of the graft, graft isometricity and functional results (IKDC and Lysholm) were evaluated. RESULTS: The positioning of the femoral tunnel on the anteroposterior radiograph, expressed as a mean percentage relative to the medial border of the tibial plateau, was 54.6% in group 1 and 60.8% in group 2 (p < 0.05). The positioning of the femoral tunnel on the lateral radiograph, expressed as a mean percentage relative to the anterior border of Blumensaat's line, was 68.4% in group 1 and 58% in group 2 (p < 0.05). The mean inclination of the graft was 19° in group 1 and 27.2° in group 2 (p < 0.05). The mean graft isometricity was 0.96 mm in group 1 and 1.33 mm in group 2 (p > 0.05). Group 2 had better results from the pivot-shift maneuver (p < 0.05). CONCLUSION: The technique of two incisions allowed positioning of the femoral tunnel that was more lateralized and anteriorized, such that the graft was more inclined and there was a clinically better result from the pivot-shift maneuver. There was no difference in isometricity and no final functional result over the short follow-up time evaluated.


OBJETIVO: Comparar as técnicas transtibial e de duas incisões na reconstrução do ligamento cruzado anterior (LCA) com banda única. MÉTODOS: Foi feito um estudo prospectivo e randomizado em bloco. Os pacientes foram submetidos a reconstrução do LCA por meio de duas técnicas: transtibial (grupo 1: 20 pacientes) ou de duas incisões (grupo 2: 20 pacientes). Foram avaliados o posicionamento radiográfico dos túneis, a inclinação do enxerto, a isometricidade do enxerto e os resultados funcionais (IKDC e Lysholm). RESULTADOS: O posicionamento do túnel femoral na radiografia em AP expresso em porcentagem em relação à borda medial do planalto tibial no grupo 1 foi em média de 54,6% e no grupo 2 foi de 60,8% (p < 0,05). O posicionamento do túnel femoral na radiografia em P expresso em porcentagem em relação à borda anterior da linha de Blumensaat no grupo 1 foi em média de 68,4% e no grupo 2 foi de 58% (p < 0,05). A inclinação do enxerto no grupo 1 foi em média de 19 graus e no grupo 2 foi de 27,2 graus (p < 0,05). A isometricidade do enxerto no grupo 1 foi em média de 0,96 mm e no grupo 2 foi de 1,33 mm (p > 0,05). O grupo 2 apresentou melhores resultados pela manobra de Pivot-Shift (p < 0,05). CONCLUSÃO: A técnica de duas incisões permitiu um posicionamento do túnel femoral mais lateralizado e anteriorizado e que o enxerto ficasse mais inclinado e demonstrou clinicamente um melhor resultado pela manobra de Pivot-Shift. Não houve diferença na isometricidade e no resultado funcional final no curto tempo de seguimento avaliado.

ABSTRACT

Since the discovery of sensorial receptors (mechanoreceptors) in the fibers of the anterior cruciate ligament (ACL) in humans, science has been trying to prove and measure its neurosensorial function as well as its correlation with the changes in the neuromuscular activation of the knee extensors (quadriceps) and flexors (hamstrings). The purpose of the study was to investigate the existence of proprioceptive deficits, using a strength reproduction test on the hamstrings, between the injured and uninjured limb (i.e., contralateral normal), in individuals who suffered complete tearing of the anterior cruciate ligament (ACL).Twenty-eight patients with complete tearing of the ACL participated in the study, (2 women e 26 men); age: 28,4 ± 6,2 anos; wheigth: 84,0 ± 12,5 kg; heigth: 169,6 ± 33,0 cm, who were waiting for surgical reconstruction of this ligament at Instituto Nacional de Traumatologia e Ortopedia Jamil Haddad (INTO), Rio de Janeiro, Brazil. A voluntary maximum isometric strength (VMIS) test was performed, followed by the reproduction of the hamstrings muscle strength test in the limb with complete tearing of the ACL and the healthy contralateral limb, with the knee flexed at 60°. The metaintensity used for the procedure was 20% of the VMIS and the proprioceptive performance was determined by means of absolute error, variable error and constant error values. Significant differences were found between the limbs (ACL rupture and contralateral) in the VMIS test (p<0,001). Differences were also found for the variables of constant error (p<0,001) and variable error (p<0,001) in the reproduction muscle strength test. No difference was found in relation to absolut error. Our data corroborate the hypothesis that, there is a proprioceptive deficit in subjects with complete ACL tearing in the injured limb, in comparison with the uninjured limb, using the reproduction of hamstrings muscle strength test. The VMIS was bigger in the uninjured limb.
