Internal Fixation for High Tibial Osteotomy

From 1988 to 1992, 91 cases of high tibial osteotomy were performed using four types of internal fixation methods. Group A, consisted of 14 cases fixed by stapling. Group B, consisted of 24 cases fixed by plating located on the lateral side of the tibia. Group C, consisted of 17 cases fixed by lateral side plating in combination with medial side stapling. Group D, consisted of 36 cases, fixed by medial side plating in combination with lateral side stapling.Postoperative changes in the tibial-plateau-tibial-shaft-angle (TPTS) were measured. Decrease in TPTS of more than 2 degrees, was 28% in group A, 46% in group B, 47% in group C, and 0% in group D. This result indicates that medial side plating in combination with lateral side stapling should be recommended for internal fixation of high tibial osteotomy.
