TL;DR
This study determines the knee joint line positioning using femoral bicondylar and epicondylar distances in the Brazilian population.
Contribution
The study provides population-specific formulas for knee joint line positioning based on femoral anatomical distances in Brazil.
Findings
The average bicondylar distance was 72.11 mm in the studied population.
Formulas for estimating joint line positioning differ between men and women.
Bicondylar distance can reliably estimate joint line positioning from epicondylar distances.
Abstract
Determinar o posicionamento da altura da linha articular de joelhos a partir das referências anatômicas da distância do eixo bicortical condilar femoral e das distâncias epicondilares medial e lateral na população brasileira. Foram analisados 500 exames de ressonância magnética de joelhos de 250 mulheres e 250 homens submetidos às mensurações das medidas do eixo bicortical condilar (EBC), da distância da altura articular do epicôndilo medial (DEM) e da distância do epicôndilo lateral (DEL). A média de idade dos pacientes analisados foi de 50,91 ± 14,76 anos. A distância média do EBC foi 72,11 ± 5,93mm. As DEMs e DELs médias foram 33,39 ± 3,50mm e 26,32 ± 4,08mm. As fórmulas encontradas para estimar a distância da linha articular a partir do epicôndilo medial e lateral nos homens foram DEM = 0,4618 x EBC e DEL = 0,3615 x EBC e, nas mulheres, DEM = 0,4653 x EBC e DEL = 0,3767 x EBC para…
