Abstract: ［Abstract］ Objective To compare the efficacy of anatomical locking plate and conventional plate fixation in high tibial osteotomy for the treatment of knee osteoarthritis. Methods The clinical data of 34 patients with knee osteoarthritis admitted to Shenzhen Bao′an People′s Hospital from January 2013 to December 2018 were retrospectively analyzed. According to the fixation methods， the patients were divided into anatomical locking plate group and conventional plate group. The operation time， intraoperative bleeding volume， fracture healing time， Lysholm score of knee joint function at 3 months， 6 months and 1 year after operation， and the incidence of complications were compared between the two groups. Results There was no significant difference in bleeding volume between two groups （P>0.05）|the fracture healing time of the anatomical locking plate group was lower than that of the conventional plate group （P=0.000）|the operation time was longer inanatomical locking plate groupthan that of conventional plate group （P=0.002）. Lysholm score was higher in the anatomical locking plate group in three months，6 months and one year after operation （P<0.05）. The incidence of complications was 5.0% in the anatomical locking plate group and 35.7% in the conventional plate group. There was significant difference between the two groups （P=0.021）. Conclusion Anatomical locking platewith high tibial osteotomy could achieve satisfactory results in the treatment of knee osteoarthritis.
