We evaluated thirty-two knees after the interlocking wedge osteotomy for varus deformity. The operations were performed between 1981 and 1986 at the Saiseikai Yahata Hospital. The mean length of follow-up was 25 months (range, 7 to 65 months). No untoward technical difficulties were encountered at surgery. Early bone union was noted in all of the cases and none of the cases developed nonunion or delayed union. Ninety-four per cent of the patients had a good result. No result was a failure. In this procedure, contact area and stability at the osteotomy site are increased by an interlocking effect of the cortices and the stress under the patella is reduced by an anterior advancement of the tibial tubercle.
