Mechanical Versus Restrictive Kinematic Alignment in Robotic-Assisted Total Knee Arthroplasty: A Randomized Controlled Trial.

ABSTRACT: Background: Lower limb malalignment is a hallmark of knee osteoarthritis, with surgical correction techniques evolving from traditional mechanical alignment (MA) to kinematic alignment (KA) approaches. Restrictive kinematic alignment (rKA) represents a hybrid strategy combining principles from both techniques. This study evaluated short-term functional outcomes following robotic-assisted total knee arthroplasty (RoTKA), comparing MA versus rKA alignment strategies. Methods: This prospective, randomized, single-center study enrolled 96 patients with grade 3-4 idiopathic knee osteoarthritis (Kellgren-Lawrence classification). Patients were randomized to MA (n = 49, mean age 67 ± 9 years) or rKA (n = 47, mean age 66 ± 7 years) groups. Preoperative hip-knee-ankle (H
