Since 1986 we have performed 3 types of techniques for high tibial osteotomy (HTO), i.e., wedge, oblique and barrel vault osteotomies, on 72 knees in 57 cases. The clinical results of 50 cases (64 knees) showed that oblique osteotomy is an excellent technique and that the age of the patient is one of the important factors for obtaining good results.
We did gait analysis by means of a force plate and a hi-speed video system on HTO postoperative patients, and compared the results with those with osteoarthritis of the knee, with TKR knee and normal knees.
From the point of view of knee flexion angle, the patterns with HTO postoperative patients are more similar to those of patients with osteoarthritis of the knee than with persons with normal knees. The recovery of the knee flexion angle is not as good as that with TKR postoperative patients.
