Anterior cruciate ligament (ACL) rupture is a significant injury in male National Hockey League (NHL) players.
To determine (1) the return to sport (RTS) rate in the NHL following ACL reconstruction, (2) performance on RTS, and (3) the difference in RTS and performance between players who underwent ACL reconstruction and controls.
Cohort study; Level of evidence, 3.
NHL players undergoing ACL reconstruction were evaluated. All demographic data were analyzed. Matched controls were selected from the NHL during the same years as those undergoing ACL reconstruction. The "index year" (relative to the number of years of experience in the NHL) in controls was the same as the year that cases underwent ACL reconstruction. RTS and performance in the NHL were analyzed and compared between cases and controls. Student t tests were performed for analysis of within- and between-group variables. Bonferroni correction was used in the setting of multiple comparisons.
A total of 36 players (37 knees) meeting the inclusion criteria underwent ACL reconstruction while in the NHL. Thirty-five players were able to RTS in the NHL (97%), and 1 player returned to the international Kontinental Hockey League. Of the players who RTS in the NHL, 100% were able to RTS the season after ACL reconstruction (mean, 7.8 ± 2.4 months). Length of career in the NHL after ACL reconstruction was 4.47 ± 3.3 years. The revision rate was 2.5%. There were significantly more cases playing in the NHL at 3 (P = .027) and 4 (P = .029) years following surgery compared with controls (index year). After ACL reconstruction, player performance was not significantly different from preinjury performance. Following ACL reconstruction (or index year in controls), cases played significantly more minutes, took more shots, had better shooting percentages, and scored more goals and points than did controls (P < .01 for all). Control players did not significantly outperform cases after ACL reconstruction in any performance measure.
There is a high RTS rate in the NHL following ACL reconstruction. All players who RTS did so the season following surgery. Performance following ACL reconstruction was not significantly different from preinjury. Cases performed better than did controls in several performance measures. Controls did not outperform cases in any measured performance variable.
前交叉韧带（ACL）撕裂是男性国家冰球联盟（NHL）球员的重大损伤。
确定 NHL 中 ACL 重建后的运动回归（RTS）率、RTS 表现以及接受 ACL 重建的球员与对照组之间的 RTS 和表现差异。
队列研究；证据水平，3 级。
评估接受 ACL 重建的 NHL 球员。分析所有人口统计学数据。从 NHL 中选择与接受 ACL 重建的球员同一年的匹配对照。对照组的“索引年”（相对于在 NHL 中的经验年限）与病例接受 ACL 重建的年份相同。分析和比较病例和对照组之间 NHL 中的 RTS 和表现。使用学生 t 检验进行组内和组间变量的分析。在多次比较的情况下使用 Bonferroni 校正。
共有 36 名符合纳入标准的球员（37 个膝关节）在 NHL 中接受 ACL 重建。35 名球员能够在 NHL 中 RTS（97%），1 名球员回到国际大陆冰球联赛。在 NHL 中 RTS 的球员中，100%能够在 ACL 重建后的赛季 RTS（平均，7.8 ± 2.4 个月）。ACL 重建后在 NHL 的职业生涯长度为 4.47 ± 3.3 年。翻修率为 2.5%。与对照组相比（索引年），术后 3 年（P =.027）和 4 年（P =.029）时，接受手术的病例在 NHL 中打球的人数明显更多。ACL 重建后，球员表现与受伤前的表现无显著差异。ACL 重建后（或对照组中的索引年），病例的上场时间、射门次数、射门命中率以及进球数和得分均显著高于对照组（所有 P 值均<.01）。在任何表现测量中，对照组都没有明显优于 ACL 重建后的病例。
ACL 重建后 NHL 中有很高的 RTS 率。所有 RTS 的球员都在手术后的那个赛季做到了这一点。ACL 重建后的表现与受伤前无显著差异。病例在多个表现指标上的表现优于对照组。对照组在任何测量的表现变量中都没有优于病例。
