title: [Bone void fillers in osteotomies : If, when, and which type?]
abstract: Medial opening wedge high tibial osteotomy (HTO) is an established procedure for treating medial osteoarthritis of the knee. In order to achieve the desired amount of correction, the osteotomy gap is opened, which creates a bone void in the medial aspect of the proximal tibia. The resulting bone void can either be left alone or be addressed by interposing a variety of different bone void fillers. Autologous and allogenic fillers can be distinguished from synthetic materials. Up to now, few studies have dealt with the usefulness and necessity for bone void fillers in HTO. The following article provides an overview on the currently used bone void fillers, their specific advantages and disadvantages and their influence on clinical and radiographic outcome after HTO.
