It is important not to over-constrain the reconstruction, avoiding increased contact pressures in the patellofemoral joint, and subsequent development of arthrosis.
In order to not over-constrain the trajectories we have verified the dependence of our result on the precise choice of (x_{mathrm{f}}) and found minuscule changes only.
The closed-loop serial compliant mechanism is over- constrained because its two fixed ends produce more than three unknown reaction forces, which brings difficulty in obtaining its compliance model.
The development of a consensus about the attachments of this ligament is important so that reconstructions can recreate these and provide an anatomical restraint without over-constraining the lateral compartment.
Unlike cables, struts were set for compression barring under regular conditions, but were still able to withstand tensile forces to prevent over-constrain and hardly-deformation.
However, to minimize the risk of over-constraining the resulting timetree, we used them only as minimum time constraints.
Furthermore, the increasing number of constraints placed at the biting tooth could have over-constrained the models beyond realistic scenarios, and this would partially explain the large differences in bite force observed.
A second obstacle with TRN integration is that the explicit rule formulation used by previous studies [ 17] can over-constrain the metabolic model.
Specifically, it does not demonstrate that the additional MILP constraints do not over-constrain the problem and eliminate some non-loop containing solutions.
Actually, horizontal tunnel reconstruction seems to over-constrain the knee (although is most similar to the intact knee especially in internal-external rotations) while the vertical tunnel seems to maintain a residual laxity with respect to the normal knee.
Here we apply Gordan's theorem from linear algebra to prove for the first time that the constraints added in loopless-COBRA do not over-constrain the problem beyond the elimination of the loops themselves.
