ABSTRACT
BACKGROUND: This study aimed to compare the bone resection thickness, rate of minimal thickness insert usage, and postoperative range of motion (ROM) between robotic and navigated TKA.
METHODS: Fifty consecutive posterior-stabilized (PS) robotic TKA and 50 case-controlled PS navigated TKA were enrolled. Bone resection thickness, rate of minimal thickness insert usage, and postoperative flexion contracture over 5X00B0; were statistically compared.
RESULTS: The tibial bone resection thickness was significantly thinner in robotic TKA. The insert thickness was significantly lower, and the rate of minimal thickness insert usage was significantly higher in robotic TKA. The ROM at 3 months postoperatively and the rate of postoperative flexion contracture were comparable between the two groups.
CONCLUSION: Robotic TKA can reduce the tibial bone resection thickness and increase the rate of minimal thickness insert usage without increasing postoperative flexion contracture as compared with navigated TKA. This article is protected by copyright. All rights reserved.
