The restoration of the mechanical axis was also analyzed at final followup according to the Kennedy and White [20] classification, which considers the alignment correct when the mechanical axis is in Zone 2 or C (central) and considered as too much in varus when in Zone 1 and too much in valgus when in Zone 3
