Objectives: To evaluate the prevalence of total hip arthroplasty (THA) and total knee arthroplasty (TKA) in a population of former National Football League (NFL) players. Methods: Participants were 3913 former NFL players (participation in years 1960–2019) who completed either an online or mailed survey that included self-reported TKA and THA, year(s) of surgery and date of birth. The prevalence of TKA and THA was reported by age category and compared to published cohorts of athlete populations and general population of non-athletes in the USA. Results: 12.3% and 8.1% of sample reported TKA and THA, respectively. The prevalence of both TKA and THA was higher in former NFL players compared to US non-athletes across all ages. Prevalence of TKA was not statistically higher than in other former athlete cohorts but performed at younger ages. The prevalence of TKA and THA was higher than in other cohorts of former NFL players. Conclusion: Former NFL players had higher prevalence of arthroplasty than the general population, suggesting prior participation in American-style football may contribute to elevated risk for arthroplasty at younger ages. Understanding risk factors in style of play, lifestyle and other contributors is important to improve joint health of this population.

前国家橄榄球联盟球员全髋和膝关节置换术的患病率：与美国总人口和其他职业运动员的比较

目的：评估前国家橄榄球联盟（NFL）运动员的全髋关节置换术（THA）和全膝关节置换术（TKA）的患病率。方法：参与者是3913名前NFL球员（参加了1960-2019年），他们完成了在线或邮寄调查，其中包括自我报告的TKA和THA，手术年份和出生日期。按年龄分类报告了TKA和THA的患病率，并将其与美国已公布的运动员人数和非运动员总人数进行了比较。结果：分别报告TKA和THA的样品为12.3％和8.1％。与所有年龄段的美国非运动员相比，前NFL运动员的TKA和THA患病率更高。TKA的患病率在统计学上没有比其他前运动员队列高，但在年轻时才发生。TKA和THA的患病率高于其他前NFL运动员队列。结论：前NFL运动员的置换术患病率高于一般人群，这表明先前参加美式足球可能会导致年轻时进行置换术的风险增加。了解游戏风格，生活方式和其他因素的危险因素对于改善该人群的联合健康很重要。
