Abstract:
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.
