BACKGROUND: Prior studies in the National Basketball Association (NBA) and Women's National Basketball Association (WNBA) reported worse player performance after Achilles tendon rupture (ATR). PURPOSE/HYPOTHESIS: The purpose of this study was to compare time to return to play (RTP) and performance after ATR between NBA and WNBA athletes. It was hypothesized that there would be no relative difference between the NBA and WNBA players. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: ATRs in the NBA between 1987 and 2017 and WNBA between 2006 and 2017 were identified through a rigorous online search of articles. Included athletes had no prior leg injuries and had played ≥3 seasons before and after ATR. Sex, age, position, body mass index, height, years of experience, time to RTP, and player efficiency rating (PER) were recorded. Relative performance was measured by matching injured athletes to uninjured controls in the same league in a 1:2 ratio. Relative differences were compared between leagues, with adjustment for baseline features. Multiple regression analysis was employed to identify variables correlating with RTP and PER. RESULTS: Included were 102 professional basketball players, of whom 34 sustained ATR (21 male, 13 female). Sex/league correlated with differences in RTP ( < .001). There was a significant difference between the WNBA and NBA in PER when comparing 1 year pre- and 1 year postinjury (1.49 ± 0.25 vs 3.87 ± 0.43, respectively; mean ± SD < .001). Compared with intraleague controls, the relative difference in PER postinjury was 0.81 ± 0.11 (WNBA) and 3.9 ± 0.89 (NBA) ( < .001). Multiple regression analysis indicated that when controlling for years of experience, player position, and age, NBA players took 126 days longer than WNBA players to RTP ( < .001) and NBA players had 9.96 times increased odds of taking >200 days to RTP compared with WNBA players ( = .006). CONCLUSION: Sex/league was a significant predictor of RTP after ATR. When compared with their respective controls, NBA players saw a greater decrease in postinjury performance than WNBA players. NBA players took longer to RTP than WNBA players. ATRs appear to more negatively affect NBA players than WNBA players.
背景：此前在美国国家篮球协会（NBA）和美国女子国家篮球协会（WNBA）进行的研究报告称，跟腱断裂（ATR）后球员表现更差。 目的/假设：本研究的目的是比较NBA和WNBA运动员跟腱断裂后恢复比赛（RTP）的时间和表现。假设是NBA和WNBA球员之间不存在相对差异。 研究设计：队列研究；证据等级，3级。 方法：通过严格在线搜索文章，确定了1987年至2017年NBA以及2006年至2017年WNBA中的跟腱断裂病例。纳入的运动员此前没有腿部受伤史，且在跟腱断裂前后均已征战≥3个赛季。记录了性别、年龄、位置、体重指数、身高、比赛经验年限、恢复比赛时间以及球员效率值（PER）。通过以1:2的比例将受伤运动员与同一联盟中的未受伤对照进行匹配来衡量相对表现。对各联盟之间的相对差异进行比较，并对基线特征进行调整。采用多元回归分析来确定与恢复比赛时间和球员效率值相关的变量。 结果：纳入了102名职业篮球运动员，其中34人发生了跟腱断裂（21名男性，13名女性）。性别/联盟与恢复比赛时间的差异相关（P < .001）。比较受伤前1年和受伤后1年时，WNBA和NBA在球员效率值方面存在显著差异（分别为1.49±0.25和3.87±0.43；均值±标准差，P < .001）。与联盟内对照相比，受伤后球员效率值的相对差异在WNBA为0.81±0.11，在NBA为3.9±0.89（P < .001）。多元回归分析表明，在控制比赛经验年限、球员位置和年龄后，NBA球员恢复比赛的时间比WNBA球员长126天（P < .001），并且与WNBA球员相比，NBA球员恢复比赛时间超过200天的几率增加了9.96倍（P = .006）。 结论：性别/联盟是跟腱断裂后恢复比赛时间的重要预测因素。与各自的对照相比，NBA球员受伤后的表现下降幅度大于WNBA球员。NBA球员恢复比赛的时间比WNBA球员长。跟腱断裂似乎对NBA球员的负面影响大于WNBA球员。
