Optimal correction in high tibial osteotomy

Abstract

The results of high tibial osteotomy are closely related to post-operative alignment of the knee joint. When deviations from the predicted correcting angle in some cases are considered difference of fibula management is found to be are of the determinants. According to fibula management the knees were divided to two groups. One was wedge osteotomy with release of the tibio fibular joint and enucleation of the fibula head and the other was wedge osteotomy with the fibula osteotomy. Supposing that difference of fibula management are of the causes of the deviation, the influence of the fibula management on the correction angle was evaluated and the correction angle in high tibial osteostomy was analyzed. The achieved correcting angle was larger than the intended correcting angle in fibula osteotomy group and smaller in fibula lead group.
