Abstract

This study evaluates the relationship between intraoperative knee kinematic patterns, specifically medial pivot (MP) versus non-medial pivot (non-MP), measured by navigation during posterior-stabilized total knee arthroplasty (TKA), and postoperative clinical outcomes in patients with knee osteoarthritis and varus deformity. Among 55 patients, no significant differences were found in postoperative knee flexion, pain, patient satisfaction, expectations, or activity at one year between MP and non-MP groups, nor did intraoperative kinematics predict these outcomes. The findings suggest that intraoperative kinematic patterns assessed by navigation do not correlate with clinical results following TKA using a fixed-bearing posterior-stabilized prosthesis and image-free navigation system.
