This is the second of 2 articles on a 3-year investigation of medial collateral ligament sprains of the knee to assess the effectiveness of prophylactic knee braces in NCAA Division I college football players. Position, string, type of session, and daily brace wear were recorded. The injury rates for braced and unbraced knees were used to create an incidence density ratio. The data were stratified and simultaneously controlled for position, string, and session and evaluated for their statistical significance. The 987 Big Ten players generated 155,772 knee exposures over the study period (50% braced). Noticeable differences existed in the rates of injury for the braced and unbraced knees in almost every position during practices, depending on player or nonplayer status. When the influential factors of position, string, and session are considered, there is a consistent but not statistically significant tendency for the players wearing preventive knee braces to experience a lower injury rate than for their unbraced counterparts. For starters and substitutes in the line positions, as well as the linebackers and tight ends, there was a consistent trend toward a lower injury rate in both practices and games. The braced players in the skill positions (backs/kickers), at least during games, exhibited a higher injury rate.
这是关于对膝关节内侧副韧带扭伤进行为期3年调查的两篇文章中的第二篇，旨在评估预防性护膝对美国大学体育协会（NCAA）第一分区大学橄榄球运动员的有效性。记录了位置、阵容、训练类型和每日护膝佩戴情况。使用佩戴护膝和未佩戴护膝的膝盖损伤率来创建发病率密度比。对数据进行分层，并同时控制位置、阵容和训练类型，评估其统计学意义。在研究期间，987名十大联盟球员产生了155,772次膝盖暴露（50%佩戴护膝）。在训练期间，几乎每个位置佩戴护膝和未佩戴护膝的膝盖损伤率都存在明显差异，这取决于球员或非球员身份。当考虑位置、阵容和训练类型等影响因素时，佩戴预防性护膝的球员受伤率低于未佩戴护膝的球员，这一趋势始终存在，但在统计学上并不显著。对于锋线位置的首发球员和替补球员，以及线卫和近端锋，在训练和比赛中受伤率都有持续下降的趋势。在技术位置（后卫/踢球手）的佩戴护膝球员，至少在比赛期间，受伤率较高。
