While knee injuries are treated by a wide range of clinicians, patients with knee injuries frequently present to emergency departments (EDs). The knee is the most commonly injured joint by adolescent athletes with an estimated 2.5 million sports-related injuries presenting to EDs annually.
The objective was to examine the epidemiology of knee injuries presenting to EDs in the United States from 1999 through 2008.
The Consumer Product Safety Commission National Electronic Injury Surveillance System database (NEISS) was used to examine causes of knee injuries treated in U.S. EDs from 1999 through 2008.
An estimated 6,664,324 knee injuries presented to U.S. EDs from 1999 through 2008, for a rate of 2.29 knee injuries per 1,000 population. Those 15 to 24 years of age had the highest injury rate (3.83), while children younger than 5 years had the lowest rate (0.55). The most common diagnoses were strains and sprains (42.1%), contusions and abrasions (27.1%), and lacerations and punctures (10.5%). The most common general product categories causing injury were sports and recreation (49.3%), home structures (30.2%), and home furnishings (13.6%). Several sex and age group differences were identified. For example, males sustained a higher proportion of basketball-related injuries (11.1%) than females (3.6%; injury proportion ratio [IPR] = 3.11, 95% confidence interval [CI] = 2.79 to 3.46, p < 0.001). Additionally, individuals 65 years and older sustained a higher proportion of injury due to stairs, ramps, landings, and floors (42.0%), compared to all other ages (20.1%; IPR = 2.09, 95% CI = 1.95 to 2.23, p < 0.001).
Rates and patterns of knee injuries vary by sex and age. Although knee injuries will likely continue to occur most frequently among youth and young adult athletes, anticipating and responding to trends such as an increase in the incidence of knee injuries among adult and senior patients will enable clinicians to better anticipate caseloads, allocate resources, and determine best practices for diagnosis and treatment of knee injuries in different age groups.
尽管有许多临床医生可以治疗膝关节损伤，但膝关节损伤患者经常会去急诊室（ED）就诊。在青少年运动员中，膝关节是最常见的受伤关节，每年约有 250 万例与运动相关的损伤需要到 ED 就诊。
本研究旨在分析美国 1999 年至 2008 年期间 ED 就诊膝关节损伤的流行病学特征。
利用消费者产品安全委员会国家电子伤害监测系统数据库（NEISS），分析了 1999 年至 2008 年期间美国 ED 治疗的膝关节损伤的病因。
估计 1999 年至 2008 年期间，美国 ED 共收治了 6664324 例膝关节损伤患者，发病率为每 1000 人中有 2.29 例膝关节损伤。15 至 24 岁人群的发病率最高（3.83%），而 5 岁以下儿童的发病率最低（0.55%）。最常见的诊断是拉伤和扭伤（42.1%）、挫伤和擦伤（27.1%）以及撕裂伤和穿刺伤（10.5%）。最常见的一般产品类别是运动和娱乐（49.3%）、家庭结构（30.2%）和家庭用品（13.6%）。还发现了一些性别和年龄组差异。例如，男性因篮球相关损伤而就诊的比例（11.1%）高于女性（3.6%；损伤比例比 [IPR] = 3.11，95%置信区间 [CI] = 2.79 至 3.46，p < 0.001）。此外，65 岁及以上人群因楼梯、斜坡、平台和地板受伤的比例（42.0%）高于其他所有年龄组（20.1%；IPR = 2.09，95%CI = 1.95 至 2.23，p < 0.001）。
膝关节损伤的发生率和模式因性别和年龄而异。尽管膝关节损伤可能仍会在青年和年轻成年运动员中最常发生，但预测和应对发病率的上升趋势，如成年和老年患者中膝关节损伤的发病率上升，将使临床医生能够更好地预测病例量、分配资源，并确定不同年龄段膝关节损伤的诊断和治疗最佳实践。
