We report two cases of osteonecrosis of the femoral medial condyle treated using high tibial osteotomy (HTO) together with mosaicplasty.
Because both patients were comparatively young and the affected area had shown no improvement with conservative treatment, we performed mosaicplasty using HTO together with open wedge. Valgus correction of about 11 degrees and 10 degrees was obtained in each FTA, and there was no correction loss observed at the time of the last follow-up. However in one case, although the condition of the graft appeared good by MRI, partial necrosis was present, suggesting the need for careful long-term follow-up.
