Is There an Indication for Correcting a Valgus Knee?

While most procedures in the treatment of patellofemoral instability address the static or dynamic stabilizers of the patella, there are still other factors that need to be considered during the process of preoperative decision-making. Limb malalignment and its resultant force vectors are one such important factor for normal biomechanical function of the lower extremity. Frontal plane valgus deformity is particularly important, as it may lead to chronic patellofemoral instability and lateral dislocation . Consequently, soft tissue procedures performed with a background of such preexisting deformity show a higher rate of failure .
