Description
The strain within the native LCL and sMCL was linearly associated with coronal lower limb alignment. Strain levels associated with microdamages to the ligaments of more than 4% were observed at 4° of varus and 5° of valgus malalignment, respectively. When considering reconstruction of the posterolateral/posteromedial corner, an additional correction of the mechanical axis should be considered in cases of lateral and medial instability accompanied by a varus/valgus malalignment exceeding 4 – 5° to protect the graft.
