Accurate projections of future demand require constant updates of current data. This article reviews the most recent usage data for primary total joint arthroplasty (TJA) in a community-based hospital system with 3.2 million members. We used administrative databases to determine plan membership, surgical volume, and age-adjusted incidence rates for TJA from 1996 through 2009. The annual growth rate in surgical volume peaked in 2002 at 18% and decreased to 3% by 2009. The annual growth rate for age-adjusted incidence rates peaked in 2002 at 13% and declined to 2% in 2009. In our population, the incidence of TJA continues to rise but at a much slower pace than in recent years.
准确预测未来的需求需要不断更新当前的数据。本文回顾了一个拥有 320 万成员的基于社区的医院系统中初次全关节置换术（TJA）的最新使用数据。我们使用管理数据库来确定 1996 年至 2009 年期间的 TJA 计划成员、手术量和年龄调整后的发病率。手术量的年增长率在 2002 年达到 18%的峰值，到 2009 年下降到 3%。年龄调整后的发病率的年增长率在 2002 年达到 13%的峰值，到 2009 年下降到 2%。在我们的人群中，TJA 的发病率仍在继续上升，但速度比近年来慢得多。
