Coronal malposition effects in total knee arthroplasty: a finite element analysis
European Journal of Orthopaedic Surgery & Traumatology, 07/31/2012
Stan G et al. – The authors found that maximum contact pressure and underlying bone compression forces are higher for a balanced knee with an inclined interline than in ideal alignment, but lower than in an unbalanced knee. According to the results, 2– and 4–mm additional medial plateau resection on a proper balanced knee does not significantly affect the load distribution towards ideal alignment. Balancing is a key factor for prosthetic survival in cases when a certain degree of coronal malposition cannot be avoided.
