Abstract

Open-wedge high tibial osteotomy (HTO) is becoming increasingly popular for the treatment of varus gonarthrosis in the active patient. Various implants can be used that differ with regard to fixation stability, design and osteotomy technique. Some risk factors are associated with a poor clinical outcome, such as a fracture of the opposite cortex and an imprecise osteotomy. In this clinical study, serial Radiostereometric Analysis (RSA) and long lower limb weight-bearing radiographs were used to (1) quantify micromotion between fixated tibial segments and (2) the amount of revarisation over time. It was found that a high primary stability offered by a long and rigid internal fixator is associated with favorable clinical results.
