Os autores avaliam 100 crianças normais da população geral de ambos os sexos entre 5 e 9 anos de idade com o objetivo de verificar e avaliar o chamado índice do arco plantar e a ocorrência de pé plano. A avaliação do pé plano o foi feita através da obtenção da impressão plantar e do cálculo do índice do arco plantar (IP) que estabelece a relação entre a região central e posterior dessa impressão, determinando-se um IP médio e um limite para esse tipo de pé. Concluem que o índice do arco plantar é facilmente obtido a partir da impressão plantar, não existirem diferenças entre os sexos e faixas etárias, que os valores médios do índice do arco plantar nessa faixa etária são estáveis e estão entre 0,61 e 0,67 e que índices do arco plantar acima de 1,15 devem ser considerados como indicativos de pé plano.
ObjectiveTo compare the transtibial and two-incision techniques for anterior cruciate ligament (ACL) reconstruction using a single band.MethodsA 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.ResultsThe 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).ConclusionThe 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.
CONTEXT AND OBJECTIVE: In the past, changes in tibial slope were not considered when planning or evaluating osteotomies, and success in high tibial osteotomy was related to the alignment and amount of femorotibial angular correction. The aim here was to measure changes in tibial slope after medial opening wedge tibial osteotomy and investigate the effect of tibial slope angle on the clinical results.
DESIGN AND SETTING:Retrospective review study on a series of cases, at the Department of Orthopedics and Traumatology, Faculdade de Medicina de Marília (Famema), Marília, Brazil.
METHODS:Twenty-eight patients were studied, and a total of thirty-one knees. Lateral roentgenograms of the tibia were used pre and postoperatively to measure the tibial slope based on the proximal tibial anatomical axis. The clinical results were measured using the Lysholm knee score.
RESULTS:There was an average increase in tibial slope angle after surgery of 2.38° (95% confidence interval: ± 0.73°). There was no correlation (r = -0.28) between the postoperative Lysholm knee score and the difference in tibial slope angle from before to after surgery (P = 0.13).CONCLUSION: Medial opening wedge tibial osteotomy led to a small increase in tibial slope. No significant correlation was found between increased tibial slope and short-term clinical results after high tibial osteotomy. Other clinical studies are needed in order to establish whether extension or flexion osteotomy could benefit patients with medial compartment gonarthrosis.
RESUMO
CONTEXTO E OBJETIVO:No passado, alterações no ângulo de inclinação ântero-posterior do planalto tibial (AIAPPT), conhecido como "slope", não eram levadas em consideração no planejamento e avaliação das osteotomias, e o sucesso da osteotomia proximal tibial era relacionado ao grau de correção do ângulo femoro-tibial e ao alinhamento obtido. O objetivo foi mensurar a alteração no AIAPPT após a osteotomia proximal de abertura de cunha medial da tíbia e verificar o efeito da variação angular do AIAPPT sobre os resultados clínicos.
TIPO DE ESTUDO E LOCAL:
MÉTODOS:Foram incluídos 28 pacientes, e um total de 31 joelhos. Foi mensurado o AIAPPT baseado no eixo anatômico proximal tibial na radiografia lateral da tíbia no pré e no pós-operatório. A avaliação clínica foi realizada através do escore de Lysholm para joelho.
RESULTADOS:Houve um aumento do AIAPPT após a cirurgia em média de 2,38° (± 0,73°; intervalo de confiança, IC 95%). Não houve correlação (r = -0,28) entre os resultados obtidos pelo escore de Lysholm pós-operatório e a diferença do AIAPPT pós e pré-operatório (P = 0,13).CONCLUSÃO: A osteotomia valgizante da tíbia proximal com cunha de abertura medial levou a um pequeno aumento no AIAPPT. Não houve correlação entre o aumento do slope tibial e os resultados clínicos a curto prazo após a osteotomia proximal da tíbia. Outros estudos clínicos são necessários para comprovar se uma osteotomia de extensão ou de flexão pode trazer benefício ao paciente com artrose unicompartimental do joelho.
