National Football League (NFL) players who undergo anterior cruciate ligament (ACL) reconstruction have been shown to have a lower return to play (RTP) than previously expected. However, RTP in the NFL after revision ACL reconstruction (RACLR) is not well defined.
PURPOSE/HYPOTHESIS: The purpose of this study is to determine the RTP of NFL players after RACLR and evaluate factors that predict RTP. Our hypothesis was that more experienced and established players would be more likely to RTP after RACLR.
Cohort study; Level of evidence, 3.
A total of 24 NFL players who underwent RACLR between 2007 and 2014 were reviewed and evaluated. Return to NFL play, time to return, seasons and games played prior to and after revision surgery, draft status, and demographic data were collected. Overall RTP was determined, and players who did RTP were compared with those unable to RTP. Data were also compared with control players matched for age, position, size, and experience.
After RACLR, 79% (19/24) of NFL players returned to NFL regular-season play at an average of 12.6 months. All players who were drafted in the first 4 rounds, played in at least 55 games, or played 4 seasons of NFL play prior to injury were able to RTP. Players drafted in the first 4 rounds of the NFL draft were more likely to RTP than those who were not (odds ratio, 0.1; 95% CI, 0.01-1.00; = .05). Those who returned to NFL play played in significantly less games and seasons after their injury than before ( = .01 and = .01, respectively). However, these values did not differ when compared with matched controls ( = .67 and = .33).
NFL players who RTP after RACLR do so at a similar rate but prolonged time period compared with after primary ACL reconstruction. Athletes who were drafted in earlier rounds were more likely to RTP than those who were not. Additionally, player experience prior to injury is an important factor when predicting RTP after RACLR.
接受前交叉韧带（ACL）重建手术的美国国家橄榄球联盟（NFL）球员的重返赛场率（RTP）低于先前预期。然而，ACL翻修重建术（RACLR）后NFL球员的RTP情况尚不明确。
目的/假设：本研究旨在确定NFL球员在RACLR后的RTP情况，并评估预测RTP的因素。我们的假设是，经验更丰富、地位更稳固的球员在RACLR后更有可能重返赛场。
队列研究；证据等级为3级。
回顾并评估了2007年至2014年间接受RACLR的24名NFL球员。收集了重返NFL赛场的情况、重返时间、翻修手术前后的赛季数和比赛场次、选秀顺位以及人口统计学数据。确定总体RTP情况，并将成功重返赛场的球员与未能重返赛场的球员进行比较。还将数据与年龄、位置、体型和经验相匹配的对照球员进行了比较。
RACLR后，79%（19/24）的NFL球员平均在12.6个月后重返NFL常规赛。所有在前四轮被选中、受伤前至少参加过55场比赛或参加过四个赛季NFL比赛的球员都能够重返赛场。在NFL选秀前四轮被选中的球员比未被选中的球员更有可能重返赛场（优势比，0.1；95%可信区间，0.01 - 1.00；P = 0.05）。那些重返NFL赛场的球员受伤后的比赛场次和赛季数明显少于受伤前（分别为P = 0.01和P = 0.01）。然而，与匹配的对照组相比，这些数值没有差异（P = 0.67和P = 0.33）。
与初次ACL重建术后相比，RACLR后重返赛场的NFL球员比例相似，但重返时间更长。较早轮次被选中的运动员比未被选中的运动员更有可能重返赛场。此外，受伤前的球员经验是预测RACLR后RTP的一个重要因素。
