National Basketball Association (NBA) players who return to sport (RTS) after Achilles tendon rupture have been reported to have poor outcomes.
To evaluate the effect of Achilles tendon ruptures on player performance and career longevity in NBA athletes.
Cohort study; Level of evidence, 3.
NBA players who sustained Achilles tendon ruptures between 1970 and 2019 were identified using publicly available resources and were matched 1:1 to a healthy control group by age, position, height, and body mass index. Demographic characteristics, player utilization (games and minutes), and performance efficiency rating (PER) were documented for all athletes. The season of Achilles tendon rupture was set as the index year, and statistical analysis compared postindex versus preindex data both acutely and in the long term. Percentages relative to preoperative values were calculated to compare the injured and control groups in a standardized fashion.
Of 47 players, 34 (72.3%) with Achilles tendon ruptures returned to play at the NBA level after surgical intervention. A total of 7 players were excluded from the study. No differences were found in demographic characteristics or PER (2 years before injury) between the remaining 27 players and matched controls. The injured players had significantly shorter careers compared with control players (3.1 ± 2.3 vs 5.8 ± 3.5 seasons, respectively; < .05). Injured players demonstrated significant declines in games per season (GPS), minutes per game (MPG), and PER at 1 year and 3 years after RTS compared with preindex baseline ( < .05). Injured players, compared with control players, had reduced relative percentages of games started (GS) (50% vs 125%, respectively), MPG (83% vs 103%), and PER (80% vs 96%) at 1 year after return ( < .05), but reductions at extended 3-year follow-up were seen only in GPS (71% vs 91%) and GS (39% vs 99%) ( < .05).
Our study found that 72.3% of NBA players returned to play after Achilles tendon repair, but they had shorter careers compared with uninjured controls. Players returning from Achilles tendon repairs had decreased game utilization and performance at all time points relative to their individual preindex baseline. However, for the injured players when compared with controls, game utilization but not performance was found to be decreased at 3-year follow-up.
据报道，美国职业篮球联赛（NBA）球员在跟腱断裂后重返赛场（RTS）的结果不佳。
评估跟腱断裂对NBA运动员比赛表现和职业生涯长度的影响。
队列研究；证据等级，3级。
利用公开可用资源确定1970年至2019年间发生跟腱断裂的NBA球员，并根据年龄、位置、身高和体重指数将其与健康对照组进行1:1匹配。记录所有运动员的人口统计学特征、球员使用率（比赛场次和上场时间）以及表现效率评级（PER）。将跟腱断裂的赛季设定为索引年，统计分析比较索引年后与索引年前的数据，包括急性期和长期数据。计算相对于术前值的百分比，以标准化方式比较受伤组和对照组。
47名球员中，34名（72.3%）跟腱断裂的球员在手术干预后重返NBA赛场。共有7名球员被排除在研究之外。其余27名受伤球员与匹配的对照组在人口统计学特征或受伤前2年的PER方面没有差异。与对照组球员相比，受伤球员的职业生涯明显更短（分别为3.1±2.3个赛季和5.8±3.5个赛季；P<.05）。与索引年前的基线相比，受伤球员在重返赛场后1年和3年时，每个赛季的比赛场次（GPS）、每场比赛的上场时间（MPG）和PER均显著下降（P<.05）。与对照组球员相比，受伤球员在重返赛场1年后，首发比赛（GS）的相对百分比降低（分别为50%和125%），MPG降低（83%和103%），PER降低（80%和96%）（P<.05），但在3年的延长随访中，仅GPS（71%和91%）和GS（39%和99%）出现降低（P<.05）。
我们的研究发现，72.3%的NBA球员在跟腱修复后重返赛场，但与未受伤的对照组相比，他们的职业生涯更短。跟腱修复后重返赛场的球员在所有时间点相对于其各自索引年前的基线，比赛使用率和表现均有所下降。然而，与对照组相比，受伤球员在3年随访时，比赛使用率下降，但表现并未下降。
