Experience of Domed High Tibial Osteotomy in Osteoarthritis of the Knee joint

Abstract

Post-operative results are evaluated in twelve knee joints of the twelve patients with knee disorders (eleven of osteoarthritis and one of osteonecrosis) treated surgically by domed high tibial osteotomy. Followed-up period are ranged from eight to twenty months. There were varus deformity in all the cases except for one. Pain and effusion were effectively relieved post-operatively in all of them. They showed a satisfaction with the postoperative results. In the post-operative course, valgus position obtained by osteotomy is found to return to varus posion with decrease of four to seven degrees of femoro-tibial angle (FTA). So carefull management will be necessary to avoid recurring of varus deformity after surgery untill bony fusion is completed at the osteotomy site.
