The purpose of this study was to evaluate the results of total knee arthroplasty (TKA) following a closed wedge high tibial osteotomy (HTO). A total of 16 TKAs were performed in 13 patients who had previously undergone a closed wedge HTO. The clinical results were reviewed using the Hospital for Special Surgery (HSS) score. The radiographic results were evaluated with respect to the femorotibial angle (FTA), joint line height (JLH) and tibial bone resection. The average HSS score before TKA was 63.6, which improved to 92.8 at the last follow-up. The FTA averaged varus 0.9 preoperatively and valgus 5.7 at the last follow-up. The JLH averaged 13.9 mm preoperatively and 15.6 mm at the last follow-up. The amount of tibial bone resection averaged 4.8 mm. A meticulous surgical technique can produce satisfactory results in TKA after HTO, considering the correction of the deformity, JLH and the amount of the tibial bone resection.
本研究旨在评估闭合楔形胫骨高位截骨术（HTO）后全膝关节置换术（TKA）的结果。13 例患者先前接受过闭合楔形 HTO，共进行了 16 例 TKA。使用特殊外科医院（HSS）评分评估临床结果。使用 femorotibial 角（FTA）、关节线高度（JLH）和胫骨骨切除来评估放射学结果。TKA 前的平均 HSS 评分为 63.6，最后一次随访时提高至 92.8。FTA 术前平均为 0.9 度内翻，最后一次随访时为 5.7 度外翻。JLH 术前平均为 13.9 毫米，最后一次随访时为 15.6 毫米。胫骨骨切除量平均为 4.8 毫米。考虑到畸形矫正、JLH 和胫骨骨切除量，精细的手术技术可以在 HTO 后 TKA 中产生满意的结果。
