Our aim in performing this study was to evaluate whether fantasy and wins above replacement (WAR) scores of athletes undergoing anterior cruciate ligament (ACL) reconstructive surgery in the National Football League (NFL), National Basketball Association (NBA), National Hockey League (NHL), and Major League Baseball (MLB) could be utilized in evaluating their performance post-surgery. We identified publicly accessible data on professional athletes from 1992 to 2015. Fantasy and WAR scores were calculated for each player. A total of 83 professional players met the inclusion criteria for this cross-sectional study. Decreased fantasy scores ranged from 33% to 42% across the four leagues after the index operation. NHL players had the lowest return-to-play (RTP) rate at 11/17 (82%), and MLB players had the highest RTP rate at 14/15 (93%). RTP rates of NBA and NFL players were comparable at 22/26 (85%) and 22/25 (88%), respectively. NFL players had the lowest average career length after surgery at 26 months, while NBA players had the longest average career length at 64 months. MLB players on average required the longest time to return to the pre-surgical level of performance (21 months). NHL players had the shortest average recovery time (eight months), and NBA players had the longest average recovery time (13 months). Approximately, more than half of all the studied players exhibited a decline in fantasy or WAR scores. In addition, NFL players had the lowest average career length, and NBA players enjoyed the longest average career length after surgery. NHL players had the lowest recovery time, while NBA players had the longest recovery time. The strength of this study is the utilization of fantasy points and WAR scores as a single unifying measure of a player's performance, which acts as an objective measure after ACL reconstruction. The average performance of a professional athlete, as evaluated through their fantasy score output, tends to decrease after undergoing ACL reconstruction. There is an overall long-term performance decline after initial spikes in their performance after surgery. Additional larger studies are needed to fully understand the effects of ACL reconstruction in professional athletes; however, the use of fantasy scores may be an objective tool in measuring the success rate of ACL reconstruction.
我们开展这项研究的目的是评估美国国家橄榄球联盟（NFL）、美国职业篮球联赛（NBA）、国家冰球联盟（NHL）和美国职业棒球大联盟（MLB）中接受前交叉韧带（ACL）重建手术的运动员的幻想积分和超过替代水平的胜场数（WAR）得分是否可用于评估他们术后的表现。我们确定了1992年至2015年公开可得的职业运动员数据。计算了每位运动员的幻想积分和WAR得分。共有83名职业运动员符合这项横断面研究的纳入标准。在接受索引手术后，四个联盟中幻想积分下降幅度在33%至42%之间。NHL运动员的复出率最低，为11/17（82%），而MLB运动员的复出率最高，为14/15（93%）。NBA和NFL运动员的复出率相当，分别为22/26（85%）和22/25（88%）。NFL运动员术后的平均职业生涯长度最短，为26个月，而NBA运动员的平均职业生涯长度最长，为64个月。MLB运动员平均需要最长时间才能恢复到术前的表现水平（21个月）。NHL运动员的平均恢复时间最短（8个月），而NBA运动员的平均恢复时间最长（13个月）。大约超过一半的研究运动员的幻想积分或WAR得分出现了下降。此外，NFL运动员的平均职业生涯长度最短，而NBA运动员术后的平均职业生涯长度最长。NHL运动员的恢复时间最短，而NBA运动员的恢复时间最长。这项研究的优势在于将幻想积分和WAR得分用作衡量运动员表现的单一统一指标，这在ACL重建后是一种客观的衡量标准。通过幻想积分输出评估的职业运动员的平均表现，在接受ACL重建后往往会下降。在术后表现最初出现峰值后，整体长期表现会下降。需要更多更大规模的研究来全面了解ACL重建对职业运动员的影响；然而，使用幻想积分可能是衡量ACL重建成功率的一种客观工具。
