A computer model to simulate patellar biomechanics following total knee replacement: the effects of femoral component alignment.
The objective of this study is to analyze the biomechanics of the patellar component following total knee replacement. More specifically we investigated the effect of displacing the femoral component of an Insall-Burstein II total knee replacement on the patellar tracking and patello-femoral contact pressures. ⋯ Precise alignment of the prosthetic components is difficult to control during total knee replacement due to the lack of precise anatomical landmarks in the human knee joint. Consequently, the position of each prosthetic component may differ from the ideal one suggested by the manufacturer. Improper alignment of the prosthetic components during total knee replacement may lead to premature implant failure.

Tomodensitometry measurements for in vivo quantification of mechanical properties of scoliotic vertebrae.
This in vivo study investigated the mechanical properties of scoliotic vertebrae especially in the apical zone. ⋯ This study suggested the following question: Could these CT measurements be a predictive tool in scoliosis treatment?
