The use of total knee arthroplasty (TKA) has increased substantially in most Western countries. However, the trends in TKA use and changes in demographic characteristics of patients having TKA in Korea remain unclear.
QUESTIONS/PURPOSES: We documented the trends in TKA use and in the demographics of patients undergoing TKA in Korea over the past decade and determined whether current TKA use in Korea corresponds to worldwide trends.
Using the Health Insurance Review and Assessment Service of Korea database, we analyzed TKA records (n = 398,218) from 2001 to 2010 in Korea. Trends in TKA use and demographics, including numbers and rates of primary and revision TKA, growth rate and the revision burden, and age- and sex-specific rates, were estimated. They were compared with nationwide TKA registry reports from other countries, and a systematic review was performed.
Over the past decade, the primary and revision TKA rates increased by 407% and 267%, respectively. However, the revision burden remained 2%. The highest proportion was observed in 65 to 74 years old and the greatest increase in 75 to 84 years old, but a decrease was observed in those 55 to 64 years old. Women consistently had a ninefold higher TKA rate. The primary TKA rate was comparable with that of other countries, but the revision burden remained lower. In addition, old and female patients comprised considerably higher proportions in Korea.
During the past decade, TKA use in Korea has markedly increased and caught up with the use levels of most developed Western countries. Trends toward consistent growth in elderly patients and higher rates in females were observed. Appropriate healthcare strategies reflecting these trends in demographics are urgently needed in Korea.
在大多数西方国家，全膝关节置换术（TKA）的使用量大幅增加。然而，韩国 TKA 使用趋势和接受 TKA 治疗的患者人口统计学特征的变化仍不清楚。
问题/目的：我们记录了过去十年韩国 TKA 使用趋势和接受 TKA 治疗的患者人口统计学特征的变化，并确定了韩国目前的 TKA 使用情况是否符合全球趋势。
我们使用韩国健康保险审查与评估服务数据库，分析了 2001 年至 2010 年期间韩国的 398218 例 TKA 记录。估计了 TKA 使用和人口统计学趋势，包括初次和翻修 TKA 的数量和比例、增长率和翻修负担以及年龄和性别特异性比例，并与其他国家的全国性 TKA 登记报告进行了比较，并进行了系统评价。
在过去的十年中，初次和翻修 TKA 率分别增加了 407%和 267%。然而，翻修负担仍保持在 2%。最高的比例出现在 65 至 74 岁，75 至 84 岁的比例增加最大，但 55 至 64 岁的比例下降。女性的 TKA 率始终高出九倍。初次 TKA 率与其他国家相当，但翻修负担仍较低。此外，韩国的老年和女性患者比例较高。
在过去的十年中，韩国的 TKA 使用量显著增加，已赶上大多数发达国家的使用水平。观察到老年患者持续增长和女性患者比例较高的趋势。韩国迫切需要制定反映这些人口统计学趋势的适当医疗保健策略。
