A Nineteen patients with tibial plateau fractures treated in our hospital between January, 1972 and April, 1982 were studied in order to detect the causes of gonalgia following these fractures.
The fractures were grouped into six types, according to the classification of Hohl. It was concluded that the causes of gonalgia were the depression of tibial plateau, genu varum, instability of the knee, and loss of articular cartilage from degenerative change. Lateral tibial plateau depression of more than 10mm resulted in considerable genu valgum, and the total depression type of medial tibial plateau (Type D and Type F) tended to produce genu varum. Our results suggest that it is important to elevate and maintain the depressed tibial plateau by open reduction, bone grafting, and internal fixation for the former type and to maintain the reduction by medial T-plate fixation to prevent varus defromity for the latter type. If open reduction is difficult, as in cases of comminuted fracture, conservative treatment by means of closed redution, closed pinning, and an ischial weight-bearing brace was found to be useful.
