Dynamic Ligament Balance After Total Knee Arthroplasty: A Comparative Finite Element Analysis
Author(s): Helder Rocha da Silva Araujo, Andrei Machado Viegas da Trindade, Enio Chaves de Oliveira and Fernanda Grazielle da Silva Azevedo Nora*
Objectives: To compare postoperative gait biomechanics between patients aged ≤70 years and >70 years undergoing navigationassisted total knee arthroplasty (TKA), integrating intraoperative navigation data with patient-specific finite element analysis (FEA) to evaluate dynamic joint behavior and internal load distribution during gait. Methods: A retrospective analysis was performed on 402 primary unilateral TKAs implanted with the SCORE® prosthesis using the Amplivision® surgical navigation system. Intraoperative data acquisition included lower limb alignment expressed by the hip–knee–ankle (HKA) angle, dynamic ligament balance (GAP), coronal plane angular behavior (varus–valgus), femoral and tibial rotational kinematics, and implanted component dimensions. Postoperative gait biomechanics were reconstructed by .. Read More»
