Abstract

We evaluated 88 knees in 78 patients Monoplanar medial openwedge PTO was performed on 56 knees in 50 patients with a mean age of 55 ± 9 years Biplanar retrotubercle medial openwedge PTO was performed on 32 knees in 28 patients with a mean age of 57 ± 7 years Mean followup periods were 406 ± 7 months for the monoplanar PTO group and 38 ± 5 months for the biplanar retrotubercle PTO group Clinical outcome was evaluated using the hospital for special surgery scoring system and radiological outcome was evaluated by the measurements of femorotibial angle FTA patellar height and tibial slope changesIn both groups postoperative HSS scores increased significantly No significant difference was found between groups in FTA alteration but the FTA decreased significantly in both groups Patellar index ratios decreased significantly in the monoplanar PTO group InsallSalvati Index by 007 BlackburnePeel Index by 007 but not in the biplanar retrotubercle PTO group Tibial slopes were increased significantly in the monoplanar PTO group but not in the retrotubercle PTO groupBiplanar retrotubercle medial openwedge osteotomy and monoplanar medial openwedge osteotomy are both clinically effective for the treatment for varus gonarthrosis Retrotubercle osteotomy also prevents patella infera and tibial slope changes radiologically
