Randomized controlled study comparing Vanguard with KneeAlign2 navigational system versus Vanguard conventional - Vanguard with/without KneeAlign 2

There were no complications reported. The absolute differences of the femoral prosthesis, tibial prosthesis, and hip-knee-ankle angle from a neutral mechanical axis were less in the navigation group compared with those in the conventional group. Alignment outliers of the tibial prosthesis and hip-knee-ankle angle were less in the navigation group (9% and 27%, respectively) compared with those in the conventional group (31% and 49%; p = 0.01 and p =0.04, respectively).
