Kinematic Alignment Produces Improved Flexion and Forgotten Joint Scores Compared to Mechanical Alignment in Primary Medial-Pivot Knee Arthroplasty

Abstract: = 0.05). This 2-year study demonstrated that kinematic alignment led to improved mean range of motion, FJS, and a lower manipulation rate compared with mechanical alignment in patients with medial-pivot implants. Evidence specific to medial-pivot devices implanted with different alignment philosophies remains limited, and our study addresses this gap by focusing on the medial-pivot implant in a prospective multi-center cohort. Our findings suggest that kinematic alignment offers better clinical outcomes with "ball-in-socket" medial-pivot implants. The study provides level II evidence.
