Ostéotomie tibiale biplanaire proximale pour la correction combinée du varus et des anomalies de la pente tibiale postérieure
Revue de Chirurgie Orthopédique et Traumatologique(2023)
摘要
Varus malalignment combined with an increased posterior tibial slope (PTS) in the ACL deficient knee is a frequent pathology, yet treatment for this condition remains challenging. The presented biplanar osteotomy technique allows to simultaneously address both components of malalignment in a single step. A detailed preoperative planning is best achieved by means of a digital planning software and constant intraoperative imaging is performed to verify the correction angle. A bony wedge is resected along with the extension osteotomy according to the preoperative planning and the medial-opening tibial osteotomy site is filled with bone allograft. Two bicortical lag screws are placed in anterior-posterior direction to secure the extension osteotomy, whereas a plate fixation is used for the medial-open osteotomy.
