背景：前交叉韧带（ACL）断裂是美国职业足球大联盟（MLS）男性球员的重要损伤。目的：确定(1)ACL重建（ACLR）后MLS的重返运动率（RTS）， (2) RTS的时间，(3)RTS的表现，(4)进行ACL重建（ACLR）和对照组之间的RTS和表现差异。研究设计：病例对照研究；证据水平，3。方法：对1996 ~ 2012年接受ACLR治疗的MLS球员进行评价。玩家数据是从公开资源中提取的。对所有人口统计数据进行分析。对照组由年龄、身体质量指数（BMI）、性别、位置、表现和MLS经验（发生在职业生涯的2.6年，指定为“指数年”）匹配的球员组成，这些球员与接受ACLR的球员在同一年中从MLS中选择。对病例组和对照组的RTS和性能进行了分析和比较。采用学生t检验对组内和组间变量进行分析。结果：在MLS期间，共有52名符合纳入标准的球员（57个膝盖）接受了ACLR。球员平均年龄为25.6±3.98岁。40名玩家能够继续游戏（77%）。在40名球员（45个膝盖）中，38名（43个膝盖，95%）在ACLR后恢复了本赛季的比赛（平均，手术后10±2.8个月）。ACLR后MLS的平均职业生涯长度为4.0 +/- 2.8年。修正率为10%。MLS患者前交叉韧带撕裂的发生率逐年显著增加（P < 0.001），左膝前交叉韧带撕裂的发生率明显高于右膝（P = 0.002）。与损伤前相比，ACLR后MLS在RTS上的表现没有显著差异。ACLR或指数年后，MLS病例与对照组的生存率无显著差异。在指标年之后，实验组和对照组之间唯一显著的表现差异是实验组每个赛季的投篮次数（P = 0.005）和助攻次数（P = 0.005）明显多于对照组。结论：ACLR术后MLS有较高的RTS发生率。几乎所有的球员在手术后都恢复了比赛。表现与损伤前无显著差异。只有两项表现指标（投篮次数和助攻次数）在实验组和对照组之间有显著差异。发生在左膝的前交叉韧带撕裂明显多于右膝。
Background: Anterior cruciate ligament (ACL) rupture is a significant injury in male Major League Soccer (MLS) players in the United States.Purpose: To determine (1) return-to-sport (RTS) rate in MLS following ACL reconstruction (ACLR), (2) timing of RTS, (3) performance upon RTS, and (4) the difference in RTS and performance between players who underwent ACL reconstruction (ACLR) and controls.Study Design: Case-control study; Level of evidence, 3.Methods: MLS players undergoing ACLR between 1996 and 2012 were evaluated. Player data were extracted from publically available sources. All demographic data were analyzed. A control group of players matched by age, body mass index (BMI), sex, position, performance, and MLS experience (occurred at 2.6 years into career, designated "index year'') was selected from the MLS during the same years as those undergoing ACLR. The RTS and performance in the MLS were analyzed and compared between cases and controls. Student t tests were performed for analysis of within-and between-group variables.Results: A total of 52 players (57 knees) that met inclusion criteria underwent ACLR while in the MLS. Mean player age was 25.6 +/- 3.98 years. Forty players were able to resume play (77%). Of the 40 players (45 knees), 38 (43 knees; 95%) resumed play the season following ACLR (mean, 10 +/- 2.8 months after surgery). Mean career length in the MLS after ACLR was 4.0 +/- 2.8 years. The revision rate was 10%. There was a significant increase in the incidence of ACL tears in the MLS by year (P < .001), and there was a significantly (P = .002) greater number of ACL tears on the left knee as opposed to the right. Performance in the MLS upon RTS after ACLR was not significantly different versus preinjury. There was no significant difference in survival in the MLS between cases and controls after ACLR or index year. The only significant performance differences between cases and controls were that cases had significantly greater shots taken per season (P = .005) and assists (P = .005) than did controls after the index year.Conclusion: There is a high RTS rate in the MLS following ACLR. Nearly all players resumed play the season after surgery. Performance was not significantly different from preinjury. Only 2 performance measures (shots taken and assists) were significantly different between cases and controls. A significantly greater number of ACL tears occur in the left versus the right knee.
