No currently available literature evaluates the effect of Achilles tendon repair on professional baseball players in the Major League Baseball (MLB).
QUESTIONS/PURPOSES: The purpose of this study was to determine the impact of Achilles tendon rupture and repair on MLB players in terms of return to play and batting/fielding performance metrics.
Achilles tendon rupture data were retrospectively collected using information from the MLB disabled list, injury reports, MLB game summaries, player profiles, and publicly available news articles. Four pair-matched control MLB position players were selected for each of the players who underwent advanced analysis. Baseline characteristics were compared between injured players and controls using Fisher's exact or Student's test.
Overall, the incidence of Achilles tendon rupture reported in MLB has increased substantially since 1996. Rate of return to play in MLB after Achilles tendon rupture and repair is 62% for position players (non-pitchers) who suffer the injury. There was no association of injury with any player metric. Compared with injury to the non-power side, injury to the power side was associated with fewer plate appearances, fewer triples, an increase in percentage of at-bats with strikeouts, and decreased speed score.
The incidence of Achilles tendon rupture in MLB has increased substantially since 1996. While comparison suggests that overall Achilles tendon injury does not have an effect on MLB player statistics in the years following surgical repair, subset analysis of injury to the rear (power-generating) leg may lead to a decline in those statistics which denote a player's speed and running ability.
目前尚无文献评估美国职业棒球大联盟（MLB）中跟腱修复对职业棒球运动员的影响。
问题/目的：本研究的目的是确定跟腱断裂和修复对MLB球员在重返赛场以及击球/防守表现指标方面的影响。
使用来自MLB伤病名单、伤病报告、MLB比赛总结、球员资料以及公开新闻文章中的信息，回顾性收集跟腱断裂数据。对每位接受深入分析的球员，选取四名配对的MLB同位置对照球员。使用Fisher精确检验或学生t检验比较受伤球员与对照球员的基线特征。
总体而言，自1996年以来，MLB报道的跟腱断裂发生率大幅上升。跟腱断裂并修复后，MLB同位置球员（非投手）的重返赛场率为62%。受伤与任何球员指标均无关联。与非发力侧受伤相比，发力侧受伤与更少的上场击球次数、更少的三垒安打、三振出局的打席百分比增加以及速度得分降低有关。
自1996年以来，MLB中跟腱断裂的发生率大幅上升。虽然比较表明，总体而言跟腱损伤在手术修复后的几年里对MLB球员数据没有影响，但对后侧（发力）腿受伤的亚组分析可能会导致那些表示球员速度和奔跑能力的数据下降。
