Section 2.2 ‘Optimisation method’ reads:
The four ligament constraints are solved, ‘as well as possible’ and not exactly fulfilled, conversely to the three ligament constraints with a Lagrange multiplier method as in Duprey et al. (2010).
It should read:

‘The Lagrange formulation…’ equation following should read:

Section 4: ‘Conclusions’ reads:
This study showed that knee kinematics greatly depend on joint geometry. One of the limitations is of this model that the two sphere-on-plane contacts are adapted from Feikes et al. (2003) and are measured on the same subject as the ligaments.
