The purpose of this study was to determine the rate of return to play and to quantify the effect on the basketball player's performance after surgical reconstruction of the anterior cruciate ligament (ACL).
Surgical injuries involving the ACL were queried for a 10-year period (1993-1994 season through 2004-2005 season) from the database maintained by the National Basketball Association (NBA). Standard statistical categories and player efficiency rating (PER), a measure that accounts for positive and negative playing statistics, were calculated to determine the impact of the injury on player performance relative to a matched comparison group. Over the study period, 31 NBA players had 32 ACL reconstructions. Two patients were excluded because of multiple ACL injuries, one was excluded because he never participated in league play, and another was the result of nonathletic activity.
Of the 27 players in the study group, 6 (22%) did not return to NBA competition. Of the 21 players (78%) who did return to play, 4 (15%) had an increase in the preinjury PER, 5 (19%) remained within 1 point of the preinjury PER, and the PER decreased by more than 1 point after return to play in 12 (44%). Although decreases occurred in most of the statistical categories for players returning from ACL surgery, the number of games played, field goal percentage, and number of turnovers per game were the only categories with a statistically significant decrease. Players in the comparison group had a statistically significant increase in the PER over their careers, whereas the study group had a marked, though not statistically significant, increase in the PER in the season after reconstruction.
After ACL reconstruction in 27 basketball players, 22% did not return to a sanctioned NBA game. For those returning to play, performance decreased by more than 1 PER point in 44% of the patients, although the changes were not statistically significant relative to the comparison group.
Level IV, therapeutic case series.
本研究旨在确定前交叉韧带（ACL）手术重建后重返赛场的比率，并量化其对篮球运动员表现的影响。
从美国职业篮球联赛（NBA）维护的数据库中查询了10年期间（1993 - 1994赛季至2004 - 2005赛季）涉及ACL的手术损伤情况。计算了标准统计类别和球员效率评级（PER），该评级考虑了正负比赛数据，以确定损伤相对于匹配对照组对球员表现的影响。在研究期间，31名NBA球员进行了32次ACL重建手术。两名患者因多次ACL损伤被排除，一名患者因从未参加过联赛比赛被排除，另一名患者因非体育活动受伤被排除。
在研究组的27名球员中，6名（22%）未重返NBA比赛。在21名（78%）重返赛场的球员中，4名（15%）伤前PER有所增加，5名（19%）的PER与伤前相差不超过1分，12名（44%）球员重返赛场后PER下降超过1分。虽然ACL手术康复后重返赛场的球员在大多数统计类别中都出现了下降，但比赛场次、投篮命中率和场均失误次数是仅有的有统计学显著下降的类别。对照组球员在其职业生涯中PER有统计学显著增加，而研究组在重建后的赛季中PER有明显增加，尽管无统计学显著性。
27名篮球运动员ACL重建后，22%未重返NBA正式比赛。对于那些重返赛场的球员，44%的患者表现下降超过1个PER点，尽管相对于对照组，这些变化无统计学显著性。
