ABSTRACT
BACKGROUND:
The osseous geometry of the lower limb has a significant impact on knee instability after ligament injuries, and osseous malalignment has been shown to be a significant risk factor for the failure of ligament reconstruction procedures. Therefore, osteotomies around the knee have gained importance as a combined or isolated treatment option in the ligament deficient and malaligned knee. In addition to unloading of an arthritic knee compartment, osteotomies are also performed to protect a reconstructed ligament and to stabilize the joint without ligament surgery. PROCEDURE In addition to the correction of varus or valgus malalignment, correction of sagittal imbalance by modifying the tibial slope is an emerging concept. Even small modifications of the tibial slope (≤5°) have been shown to change the anterior-posterior translation in a clinically significant manner. Especially in the case of chronic posterior or posterolateral instability, a valgus-producing and slope-increasing high tibial osteotomy is usually the first treatment option, and ligament surgery is only performed optionally. Isolated modification of the tibial slope is performed infrequently, however, a slope-decreasing osteotomy should be considered in patients with multiple failed ACL reconstructions and a tibial slope of >12°.Palabras clave
