Survivorship of medial opening wedge high tibial osteotomy in the elderly: two to ten years of follow up

摘要

Background and purpose Medial opening wedge high tibial osteotomy (MOWHTO) is a well-accepted procedure, which has been widely used for pain relief and varus deformity correction in the osteoarthritic (OA) knee, especially in the young patient. However, in the elderly patient, the efficacy of this procedure is still unknown. Therefore, this study aims to evaluate the survivorship of MOWHTO in elderly patients as the primary outcome. The secondary outcome is to evaluate the loss of correction angle that is the common complication after MOWTHO. Materials and method A retrospective study of 50 elderly patients (>= 60 years) was conducted to track survivorship of MOWHTO. All patients were diagnosed with varus OA knee and underwent MOWHTO at our institute. The patients who had previous knee surgery or incomplete data were excluded.
