PURPOSE
To determine structural knee injury rates and to identify risk factors and the number of games missed associated with these injuries in National Basketball Association (NBA) players from the 2015 to 2020 seasons.
METHODS
Publicly available player records of active NBA players between the 2015 and 2020 seasons (excluding the shortened 2019 season) were reviewed to identify players with a knee injury associated with missing one or more games. Player demographics, anthropometric measurements, statistics, injury characteristics, and history of other lower-extremity injuries were recorded. We sought factors associated with having a structural knee injury in bivariate analysis and multivariable logistic regression. Negative binomial regression was conducted to evaluate factors associated with the total number of games missed.
RESULTS
Two hundred twelve players (of 1,011, 21%) sustained a structural knee injury. Accounting for potential confounders, having a structural knee injury was associated with more minutes per game played (odds ratio [OR] 1.1; 95% confidence interval [CI] 1.0-1.2; = .002), a greater usage rate (OR 1.1; 95% CI 1.0-1.2; = .004), and a lower player efficiency rating (OR 0.94; 95% CI 0.89-1.0; = .041). A greater number of missed games was associated with more minutes per game (regression coefficient [RC] 0.065; 0.028-0.10; = .001), fewer points per game (RC -0.078; -0.14 to -0.017; = .013), and greater usage rate (RC 0.032; 0.0040-0.060; = .025).
CONCLUSIONS
Structural knee injuries occurred in 21% of players in this study with an overall rate of 5.42 injuries per 1,000 game exposures. Significant risk factors associated with injury were minutes per game, usage rate, and true shooting percentage. Player efficiency was significantly associated with a decreased risk of injury. Increased minutes per game and usage rate were significantly associated with a longer duration of game loss.

目的
确定2015至2020赛季美国职业篮球联赛（NBA）球员的膝关节结构性损伤发生率，识别相关危险因素以及因这些损伤而缺阵的比赛场次。
方法
回顾2015至2020赛季（不包括缩短的2019赛季）NBA现役球员公开的比赛记录，以确定因膝关节损伤而缺阵一场或多场比赛的球员。记录球员的人口统计学特征、人体测量数据、统计数据、损伤特征以及其他下肢损伤史。我们在双变量分析和多变量逻辑回归中寻找与膝关节结构性损伤相关的因素。进行负二项回归以评估与缺阵比赛总场次相关的因素。
结果
1011名球员中有212名（21%）遭受了膝关节结构性损伤。在考虑潜在混杂因素后，膝关节结构性损伤与场均上场时间更多（比值比[OR] 1.1；95%置信区间[CI] 1.0 - 1.2；P = .002）、使用率更高（OR 1.1；95% CI 1.0 - 1.2；P = .004）以及球员效率值更低（OR 0.94；95% CI 0.89 - 1.0；P = .041）有关。缺阵比赛场次更多与场均上场时间更多（回归系数[RC] 0.065；0.028 - 0.10；P = .001）、场均得分更少（RC -0.078；-0.14至-0.017；P = .013）以及使用率更高（RC 0.032；0.0040 - 0.060；P = .025）有关。
结论
本研究中21%的球员发生了膝关节结构性损伤，每1000次比赛暴露的总体损伤发生率为5.42例。与损伤相关的显著危险因素为场均上场时间、使用率和真实投篮命中率。球员效率与损伤风险降低显著相关。场均上场时间增加和使用率提高与缺阵比赛时间延长显著相关。
证据水平
