Twenty-eight osteoarthritic knees in twenty-seven patients who underwent high tibial osteotomy were followed for mean duration of 1 year and 5 months, and evaluated through clinical, radiographic, and arthroscopic examinations.Arthroscopically, six knees showed an improvement of more than one grade by Kosino's criteria. Eight knees did not show an improvement of more than one grade, but slight regeneration of cartilage was observed. Twelve knees did not change and two knees worsened.In patients who showed improvement arthroscopically of more than one grade, the femoro-tibial angle (FTA) was below 168°, and the mechanical axis was over 40% in all knees.
