PURPOSE
To evaluate the impact anterior cruciate ligament reconstruction (ACLR) has on strike evasion rates, strike and landing rates, win percentage, and career longevity in Ultimate Fighting Championship (UFC) fighters.
METHODS
UFC fighters who underwent ACLR from 1993 to 2022 were matched 2:1 with uninjured controls. The percentage of each injured fighter's career that occurred before ACLR was deemed the "index percentage." Injured fighter performance pre-/post-ACLR was compared with control metrics pre-/postindex percentage.
RESULTS
Of the 82 patients with documented ACL injuries identified, 48 met the inclusion criteria. Of these, 27 returned for more than 2 fights and were paired with 54 controls. UFC fighters demonstrated return-to-sport rates of 81.25% and 56.25% for at least 1 and 2 fights, respectively. On average, it took 411.85 ± 174.73 (range, 165-879) days for fighters to return. All fighters had significantly lower evasion rates against total significant strikes, distance strikes, and head strikes, postindex ( < .05 for each). ACLR fighters had significantly lower submission attempts and evasion rates against clinch strikes, ground strikes, and total strikes, postindex ( < .05 for each). Controls had a significantly lower evasion rate against leg strikes, postindex. Both groups' win percentages significantly declined (ACLR, = .001; control, = .012). No significant difference in total career fights was observed ( = .873).
CONCLUSIONS
In this study, we found that most UFC fighters who undergo ACLR return to sport for at least 1 fight; however, just over half return for at least 2 fights. There was not a significant difference in career length between fighters who returned to sport following ACLR for at least 2 fights and their controls. Defensive performance, but not offensive performance, declined significantly following ACLR. All fighters demonstrated significant declines in their win percentage as their career progressed, irrespective of ACLR.
LEVEL OF EVIDENCE
Level III, retrospective comparative study.
目的
评估前交叉韧带重建术（ACLR）对终极格斗冠军赛（UFC）选手的打击闪避率、打击和着陆率、胜率以及职业生涯长度的影响。
方法
1993年至2022年接受ACLR的UFC选手与未受伤的对照组按2:1进行匹配。每位受伤选手在ACLR之前的职业生涯所占百分比被视为“指数百分比”。将受伤选手在ACLR前后的表现与对照组在指数百分比前后的指标进行比较。
结果
在确定的82例有记录的ACL损伤患者中，48例符合纳入标准。其中，27例回归参加了超过2场比赛，并与54例对照组配对。UFC选手至少参加1场和2场比赛的复出率分别为81.25%和56.25%。选手平均需要411.85±174.73（范围165 - 879）天才能复出。所有选手在指数期后对总有效打击、远距离打击和头部打击的闪避率均显著降低（每项均P<0.05）。ACLR选手在指数期后对抱摔打击、地面打击和总打击的降服尝试和闪避率均显著降低（每项均P<0.05）。对照组在指数期后对腿部打击的闪避率显著降低。两组的胜率均显著下降（ACLR组，P = 0.001；对照组，P = 0.012）。总职业生涯比赛场次未观察到显著差异（P = 0.873）。
结论
在本研究中，我们发现大多数接受ACLR的UFC选手至少复出参加1场比赛；然而，只有略超过一半的选手至少复出参加2场比赛。ACLR后至少复出参加2场比赛的选手与其对照组在职业生涯长度上没有显著差异。ACLR后防守表现显著下降，但进攻表现未下降。随着职业生涯的推进，所有选手的胜率均显著下降，无论是否接受ACLR。
证据水平
