This study investigated the post-operation period required for lesions to become stable on radiographs following high tibial osteotomy for osteonecrosis of the medial femoral condyle. Eleven knees were studied regarding the lesion size on pre-operative radiographs and at three months and one year follow-up. Cases were classified into two groups according to post-operative changes. The radiographic lesion expanded in three cases (group A) and reduced in eight case (group B). In group A, expansion of the lesion were seen until 3 months post-operatively. In group B, lesion reduction was very slow and many cases occurred during three month to one year post-operative period. Most lesions did not change in size on radiographs one year after post-operatively.
