Abstract
The purpose of this study was to evaluated the clinical outcomes of osteochondral autografting with high tibial osteotomy (HTO) in 5 female patients with idiopathic osteonecrosis of the knee. The mean patient age was 65.8 years (range, 60 to 72 years) and the average follow-up period was 30.6 months (range, 12 to 53 months). The mean preoperative JOA score of 67.0 points improved to 93.0 points postoperatively. Varus deformity of the lower extremity was improved from a mean FTA of 179.8 degrees preoperatively to 170.4 degrees postoperatively. Second-look arthroscopy demonstrated excellent cartilage repair in 4 of the 5 knees. Osteochondral autografting with HTO is one of the possible options for manegement of idiopathic osteonecrosis of the knee in elderly patients.
