背景：各种全国性研究报告了膝关节置换术和胫骨截骨术的不同年度趋势。使用日本的诊断程序组合数据库，本系列研究了全膝关节置换术（TKA）、单髁膝关节置换术（UKA）和胫骨截骨术的年度趋势和人口统计学资料。方法：所有患者均在2007年7月至2015年3月期间因膝关节骨关节炎、骨坏死或类风湿性关节炎接受TKA、UKA或胫骨截骨术。共确定了170，433例TKA、13，209例UKA和8760例胫骨截骨术。UKA患者比例从2007年的4.0%上升至2014年的8.1%（P < 0.001），胫骨截骨患者比例从2007年的2.6%上升至2014年的5.5%（P < 0.001）; TKA患者比例从2007年的93.4%下降至2014年的863%（P < 0.001）。2007年至2014年，接受UKA和胫骨截骨术的骨坏死患者比例分别从34.7%和11.6%增加到38.6%和16.2%（UKA P = 0.001，胫骨截骨术P = 0.004）。接受UKA或胫骨截骨术的骨坏死患者比例显著高于其他诊断的患者（两者均为P < 0.001）。结论：2007-2014年期间，日本UKA和胫骨截骨术的普及率增加，而TKA则有所下降。骨坏死患者中UKA和胫骨截骨的比例也增加，且大于其他病因患者。(C)2017由Elsevier B.

Background: Various nationwide studies have reported differing annual trends in utilization of knee arthroplasty and tibial osteotomy. Using the Diagnosis Procedure Combination database in Japan, the present series examined annual trends and demographics in total knee arthroplasty (TKA), unicompartmental knee arthroplasty (UKA) and tibial osteotomy.Methods: All patients were identified who underwent TKA, UKA or tibial osteotomy for osteoarthritis, osteonecrosis or rheumatoid arthritis of the knee between July 2007 and March 2015.Results: A total of 170,433 cases of TKA, 13,209 cases of UKA and 8760 cases of tibial osteotomy were identified. The proportion of patients undergoing UKA rose from 4.0% in 2007 to 8.1% in 2014 (P < 0.001), and that of tibial osteotomy from 2.6% in 2007 to 5.5% in 2014 (P < 0.001); the proportion undergoing TKA fell from 93.4% in 2007 to 863% in 2014 (P < 0.001). Between 2007 and 2014 the proportions of patients with osteonecrosis who underwent UKA and tibial osteotomy increased from 34.7% and 11.6% to 38.6% and 16.2%, respectively (P = 0.001 for UKA and P = 0.004 for tibial osteotomy). The proportions of patients with osteonecrosis undergoing UKA or tibial osteotomy were significantly greater than those with other diagnoses (P < 0.001 for both).Conclusions: The popularity of UKA and tibial osteotomy in Japan increased during the period 2007-2014 at the expense of TKA. The proportions of UKA and tibial osteotomy in patients with osteonecrosis also increased, and were larger than those in patients with other causative diseases. (C) 2017 Published by Elsevier B.V.
