ABSTRACT
RESUMEN Fundamento: el quiste de Baker es el tumor de partes blandas más frecuente de la fosa poplítea, su tratamiento puede ser conservador o quirúrgico, este último tanto por vía artroscópica o abierta. Objetivo: profundizar los conocimientos en relación al quiste de Baker en la articulación de la rodilla. Métodos: la búsqueda de la información se realizó en un periodo de tres meses (primero de octubre de 2017 al 31 de diciembre de 2017) y se emplearon las siguientes palabras: popliteal cyst y Baker's cyst, a partir de la información obtenida se realizó una revisión bibliográfica de un total de 316 artículos publicados en las bases de datos PubMed, Hinari, SciELO y Medline mediante el gestor de búsqueda y administrador de referencias EndNote, de ellos se utilizaron 50 citas seleccionadas para realizar la revisión, 45 de ellas de los últimos cinco años, donde se incluyeron cuatro libros. Resultados: se abordan la forma de presentación clínica de esta enfermedad y los estudios de tipo imaginológicos. Se hace referencia al diagnóstico diferencial entre el niño y el adulto; y entre el quiste de Baker y aneurisma de la arteria poplítea. Se describen las modalidades de tratamiento tanto conservador como quirúrgico, en relación a este último se plasman las indicaciones y variedades. Conclusiones: el quiste de Baker es el tumor de partes blandas más frecuente en la fosa poplítea, su presencia ocurre tanto en niños como en adultos y existen diferencias entre estos grupos. En el adulto se debe prestar especial interés con respecto al diagnóstico diferencial con el aneurisma de la arteria poplítea. El tratamiento en el paciente adulto por lo general es quirúrgico, tanto por vía abierta o artroscópica con muy buenos resultados.
ABSTRACT Background: Baker's cyst is the most common soft tissue popliteal tumor; treatment may be conservative or surgical by arthroscopy or open ways. Objective: to deep the knowledge about Baker's cyst in the knee joint. Methods: the search of the information was carried out in a period of three months (from October 1st, 2017 to December 31, 2017) and the following words were used: popliteal cyst and Baker's cyst, from the obtained information it was carried out a bibliographical review of a whole of 316 articles published in the databases PubMed, Hinari, SciELO and Medline by means of the information locator EndNote, of them 50 citations were selected to do the review, 45 of them of last five years, where four books were included. Development: important aspects related to clinical picture and imaging investigations were pointed out. Differential diagnosis between Baker's cyst in children and adults, and Baker's cyst and popliteal aneurysm were described. Treatment modalities were stated as well as surgical indications. Conclusions: Baker's cyst is the most common soft tissue popliteal tumor affecting children and adults with cardinal differences. Popliteal aneurysm should be always ruled out. Surgical treatment is usually needed in adults by open procedures or arthroscopy, both methods have good results.
ABSTRACT
ABSTRACT Objective To assess the influence of the body weight in functional capacity and pain of adult and elderly individuals with knee osteoarthritis. Methods The sample consisted of 107 adult and elderly patients with knee osteoarthritis divided into two groups (adequate weight/adiposity and excessive weight/adiposity) according to body mass index and percent of body fat mass, assessed by electric bioimpedance. Subjects were evaluated for functional mobility (Timed Up and Go Test), pain, stiffness and function (Western Ontario and MacMaster Universities Osteoarthritis Index − WOMAC), pain intensity (Visual Analogue Scale − VAS) and pressure pain tolerance threshold (algometry in vastus medialis and vastus lateralis muscles). Data were analyzed with Statistical Package of the Social Sciences, version 22 for Windows. Comparisons between groups were made through Student's t test, with significance level set at 5%. Results There was predominance of females in the sample (81.3%), and mean age was 61.8±10.1 years. When dividing the sample by both body mass index and adiposity, 89.7% of them had weight/adiposity excess, and 59.8% were obese. There was no difference between groups regarding age, pain intensity, pressure pain tolerance threshold, functional mobility, stiffness and function. However, pain (WOMAC) was higher (p=0.05) in the group of patients with weight or adiposity excess, and pain perception according to VAS was worse in the group of obese patients (p=0.05). Conclusion Excessive weight had negative impact in patients with osteoarthritis, increasing pain assessed by WOMAC or VAS, although no differences were observed in functionality and pressure pain tolerance.
RESUMO Objetivo Avaliar a influência do peso corporal na capacidade funcional e na dor de adultos e idosos com osteoartrite de joelho. Métodos A amostra foi constituída por 107 pacientes adultos e idosos com osteoartrite do joelho, divididos em dois grupos (peso/adiposidade adequados e peso/adiposidade em excesso), de acordo com o índice de massa corporal e a porcentagem de adiposidade corporal, e avaliados por bioimpedância elétrica. Os sujeitos foram avaliados quanto à mobilidade funcional (Timed Up and Go), dor, rigidez e função (Western Ontario and McMaster Universities Osteoarthritis Index − WOMAC), intensidade da dor (Escala Visual Analógica - EVA) e limiar de limiar de dor à pressão (algometria nos músculos vasto medial e vasto lateral). Os dados foram analisados pelo Statistical Package of the Social Sciences, versão 22 para Windows. As comparações entre os grupos foram feitas por meio do teste t de Student, com nível de significância estabelecido em 5%. Resultados Houve predomínio de mulheres na amostra (81,3%), com média de idade de 61,8±10,1 anos. Ao dividir a amostra por índice de massa corporal e adiposidade, 89,7% apresentaram peso/adiposidade em excesso, e 59,8% eram obesos. Não houve diferença entre os grupos quanto a idade, intensidade da dor, limiar de dor à pressão, mobilidade funcional, rigidez e função. Entretanto, a dor (WOMAC) foi maior (p=0,05) no grupo de pacientes com excesso de peso ou adiposidade, e a percepção da dor pela EVA foi pior no grupo de pacientes obesos (p=0,05). Conclusão O peso em excesso teve impacto negativo em pacientes com osteoartrite, aumentando a dor avaliada pelo WOMAC ou pela EVA, embora não tenham sido observadas diferenças na funcionalidade e na tolerância à dor sob pressão.
