Abstract:
Proximal tibial osteotomy is a procedure usually employed for osteoarthritis of the knee with a predominant single compartment involvement accompanied by pain and angular deformity. It has as its objective the shift of the gravitational line of weight from an involved to a relatively uninvolved side of the knee. We studied the preoperative clinical status and postoperative results in twenty-two patients (twenty-four knees) who had had a proximal osteotomy for osteoarthritic varus deformity. The mean length of follow-up was 2.6years(Range, 6months to 4.8years). In the preoperative evaluation of the lesion, we used bone scintigraphy to estimate the range and extent of the osteoarthritic change. The scintigraphic results were more sensitive to simple x-ray finding in a disease process. The range of motion of the knee were improved after osteotomy, from 7.7degree-128 degree to 2.6 degree-135degree(5.1degree in flexion contracture and 7 degree in further flexion). Correction of the tibiofemoral angle was performed to the level that we had decided correction angle to 7 degree and 3 degree of overcorrection. The correltion of good clinical results and tibiofemoral angle was dependent on whether the postoperative tibiofemoral angle is more than 5 degree valgus or not.
