Abstract：
To investigate return to play (RTP) and functional performance after anterior cruciate ligament reconstruction (ACLR) in National Basketball Association (NBA) players and to perform a systematic review of the literature to understand RTP after ACLR in professional basketball.
NBA players undergoing ACLR between 2008 and 2014 by two surgeons were identified. RTP and performance were assessed based on a review of publically available statistics. A systematic review of the literature was performed using the MEDLINE database. Inclusion criteria were: English language, ACL surgery outcome, professional basketball and RTP outcome. We reviewed studies for RTP rates and RTP performance.
Our study included 12 professional basketball players with NBA level experience. Eleven of the 12 players returned to their prior level of play. Eight of the 9 (88.9%) players actively playing in the NBA returned to play in the NBA at a mean 9.8 months. Among players returning to NBA play, during RTP season 1, mean per game statistics decreased for the following: minutes, points, rebounds, assists, steals, blocks, turnovers and personal fouls - none of these changes reached statistical significance. Player efficiency ratings significantly declined from pre-injury (12.5) to the first RTP season (7.6) (p = 0.05). By RTP season 2, player performance metrics approximated pre-injury levels and were not significantly different. Six studies met inclusion criteria; reported RTP rates ranged from 78-86%. Identified studies similarly found a decline in functional performance after RTP.
There is a high rate (89%) of return to NBA play for NBA players undergoing ACLR. After RTP, however, there is a quantitative decline in initial season 1 RTP statistics with a significant decrease in player efficiency rating. By RTP season 2, performance metrics demonstrated an improvement compared to RTP season 1 but did not reach pre-injury functional performance, though performance metrics are not significantly different between pre-injury and RTP season 2.

摘要：
调查美国国家篮球协会（NBA）球员前交叉韧带重建（ACLR）后的重返比赛（RTP）和功能表现，并对文献进行系统回顾，以了解职业篮球中ACLR后的RTP。
确定了在2008年至2014年期间由两名外科医生接受ACLR的NBA球员。RTP和绩效是根据对公开可用统计数据的审查进行评估的。使用MEDLINE数据库对文献进行了系统回顾。纳入标准为：英语，ACL手术结果,职业篮球和RTP结果。我们回顾了RTP速率和RTP性能的研究。
我们的研究包括12名具有NBA级别经验的职业篮球运动员。12名球员中有11名恢复了以前的比赛水平。在NBA积极打球的9名球员中有8名（88.9％）平均在9.8个月内重返NBA。在重返NBA的球员中，在RTP第1季期间，每场比赛的平均统计数据在以下范围内下降：分钟，点,篮板,助攻,偷窃,块,失误和个人犯规-这些变化都没有达到统计学意义。球员效率等级从受伤前（12.5）到第一个RTP赛季（7.6）显着下降（p=0.05）。到RTP第2赛季，球员的表现指标接近受伤前的水平，没有显着差异。六项研究符合纳入标准；报告的RTP率在78-86%之间。确定的研究同样发现RTP后功能性能下降。
接受ACLR的NBA球员重返NBA的比率很高（89%）。RTP之后,然而,最初的第1赛季RTP统计量下降，球员效率等级显着下降。到RTP第2季，与RTP第1季相比，性能指标有所改善，但未达到伤前功能表现，尽管受伤前和RTP第2季之间的性能指标没有显着差异。
