Correlação entre características antropométricas individuais e as medidas da fóvea tibial do ligamento cruzado anterior

Abstract

Resumo Objetivo Avaliar possíveis relações entre o peso e altura de pacientes submetidos à artroplastia total do joelho com o comprimento, largura e área da fóvea do ligamento cruzado anterior, verificados na cirurgia. Métodos Um total de 33 superfícies articulares tibias proximais, obtidas nos cortes tibiais de artroplastia total do joelho de 33 pacientes, foram utilizadas no presente estudo. O ligamento cruzado anterior foi dissecado cuidadosamente e ressecado com bisturi delicado, para expor sua fóvea. Depois, a periferia dessa fóvea foi demarcada por pequenos pontos, com um marcador. Cada peça foi fotografada e as medições do comprimento, largura e área da fóvea tibial do ligamento cruzado anterior foram feitas com o programa ImageJ (National Institutes of Health, Bethesda, MD, EUA). A análise estatística avaliou a correlação entre os dados antropométricos dos pacientes com as medidas da fóvea tibial do ligamento cruzado anterior. Resultados O comprimento, a largura e a área médios da fóvea tibial do ligamento cruzado anterior foram, respectivamente 11,7 ± 2,0 mm, 7,1 ± 1,4 mm e 151,3 ± 22,2 mm2. Houve relação estatisticamente significativa entre a altura dos pacientes e a largura da fóvea tibial do ligamento cruzado anterior. A largura da fóvea do ligamento cruzado anterior pôde ser predita pela fórmula: largura = 107,294–(133,179 × altura) + (44,009 × altura ao quadrado). Conclusão A altura dos pacientes pôde a prever a largura da fóvea tibial do ligamento cruzado anterior e, assim, pode ajudar os cirurgiões escolher o enxerto mais adequado para cada paciente, nas reconstruções do ligamento cruzado anterior.

Patient Height may Predict the Length of the Anterior Cruciate Ligament: A Magnetic Resonance Imaging Study

“…The distribution of ACL tibial footprint sizes in this study was most similar to the study by Gali et al 11 who made measurements in 33 patients underwent total knee arthroplasty (TKA) showing average tibial fovea length of 11.7 AE 2.0 mm and width of 7.1 AE 1.4 mm compared to the mean length and width from our population (11.91 AE 1.8 mm and 10.9 AE 1.9 mm). Gali et al 11 also mentioned a strong correlation between More anatomic ACL reconstruction aims to functionally restore the ACL to its native dimension, collagen orientation, and insertion sites to try to reproduce normal anatomy, restore kinematics, and provide long-term joint health. 17 In a double-bundle ACL reconstruction, it is important to avoid implanting grafts larger than the native ACL footprint, which will impede bone tendon healing and graft remodeling and result in impingement at the intercondylar notch and posterior cruciate ligament.…”

“…In almost all of the previous studies, tibial footprint length was positively correlated with weight and height or height alone of the patients. 6,[9][10][11]13 A bigger size of tibial length in the western population might be due to the higher mean height in the western population compared to ours such as the mean height in Guenther's study of 174.3 AE 10.1 versus 168.07 AE 0.1. 13 Direct measurements performed in elderly patients undergoing TKA had a different population compared to the common populations suffered from ACL injury.…”

“…Second, measurement of other anthropometric data such as leg length, femoral length, and tibial length might be included to enhance prediction equation as demonstrated by Park et al 9 Last, we conduct the population on the basis of our population, which is mostly Asian, whereas other studies previously showed variable results from different populations. [8][9][10][11]13…”

“…Several literatures have studied the correlation between patients’ weight and height with their tibial ACL insertion sizes throughout the world. 7 , 8 , 9 , 10 , 11 The purpose of this study were to measure the length and width of ACL tibial footprint using MRI and to evaluate correlation between patients’ weight and height with the tibial footprint size. We hypothesized that there was a correlation between patient’s height and weight with the ACL tibial footprint sizes.…”

Gender Differences of the ACL Insertion Sites

“…с соавторами и Y.B. Park с соавторами можно обнаружить заключение о наличии устойчивой взаимосвязи между антропометрическими данными и размерами областей прикрепления связки [49,50]. Корреляция между последними и площадью внутренней поверхности наружного мыщелка БК или суставной поверхности большеберцового эпифиза была установлена по результатам исследования T. Iriuchishima с соавторами [46].…”
