This article represents experience of using modular metal blocks for knee replacement for the replacement of defects of the tibia. Authors analyzed the results of the using of blocks that replace defect of the medial condyles tibia bone, from 2010 to 2016 years. There were twogroup of patients: comparison group and control group (the first group consist of 100 patient without defect of the condyle tibia. This patients a standard knee replacement was performed; the second group consist of 32 patient with the defects of the medial condyles tibia bone. In second group was performed a knee replacement with the using of blocks that replace defect of the medial condyles tibia bone. Periods of studies were from 2 years till 6 years. Scale KSS was applied for the evaluation of the results. Among the patients were women (90–68%), nearly one third (42–31,8%) – men, mean age - 68.4 years. Similar demographics were occurred in all groups, however, a comparative evaluation on the scale of the study and control groups in the preoperative period revealed significant differences. In the postoperative period results were similar in all groups. The applying of modular units for replacement of defects of the medial condyle of the tibia bone during knee replacement is a simple and effective method, shown with significant bone defects – more than ½ the area of the condyle, a depth of 10 mm, which is an alternative to bone grafting and allowing early activation of patients.

Keywords:osteoarthritis, osteonecrosis, modular block, knee replacement.
