Kayani B, et al. - In this prospective study, 110 individuals with symptomatic osteoarthritis of the knee who underwent primary robot-assisted posterior-stabilized (PS) TKA were involved in order to evaluate the impact of posterior cruciate ligament (PCL) resection on flexion-extension gaps, mediolateral soft-tissue laxity, fixed flexion deformity (FFD), and limb alignment during PS TKA. By extending the flexion gap more than the extension gap, PCL resection produced a flexion-extension mismatch. The rise in the lateral flexion gap was greater as that in the medial flexion gap, which built mediolateral laxity in the flexion. Moreover, betterments in FFD after PCL resection were reliant on the degree of deformity prior to the PCL resection.
