Medial opening wedge high tibial osteotomy with the navigated iBalance HTO system and early weight bearing: A Evaluation of precision and maintenance of correction after 1 year

Rohit Kulkarni

Safety and stability of the Arthrex iBalance HTO system has been demonstrated using standard surgical techniques and conventional postoperative rehabilitation protocols. The purpose of the current study was to investigate the accuracy and stability of the osteotomy following iBalance implantation using a minimally-invasive, navigated surgical technique, in combination with an accelerated rehabilitation protocol. A prospective, observational study of 20 consecutive patients undergoing medial opening HTO with the iBalance implant and a minimallyinvasive, computer-navigated surgical technique was conducted. Intraoperative stressed hip-kneeankle (HKA) angles measured with navigation were compared to 2 weeks postoperative HKA angles measured on long leg radiographs to determine the accuracy of the surgical technique.
