摘要

目的评估前交叉韧带重建术（ACLR）对终极格斗锦标赛（UFC）格斗选手的攻击规避率、攻击和着地率、胜率以及职业寿命的影响。方法将 1993 年至 2022 年期间接受前交叉韧带重建术的 UFC 格斗选手与未受伤的对照组进行 2:1 配对。每名受伤拳手在 ACLR 之前的职业生涯百分比被视为 "指数百分比"。受伤拳手在 ACLR 之前/之后的表现与对照组在指数百分比之前/之后的指标进行了比较。其中 27 人重返赛场参加了两场以上的比赛，并与 54 名对照组选手配对。UFC 选手至少参加 1 场比赛和 2 场比赛的重返赛场率分别为 81.25% 和 56.25%。选手平均需要 411.85 ± 174.73 天（165-879 天不等）才能重返赛场。在指数后，所有拳手对总重大打击、远距离打击和头部打击的规避率都明显降低（P < .05）。ACLR 格斗者的降服尝试率以及对擒拿格斗、地面格斗和总格斗的规避率在指数发布后明显降低（P 均为 0.05）。对照组对腿部打击的规避率在指数后明显降低。两组的胜率都明显下降（ACLR，P = .001；对照组，P = .012）。结论在这项研究中，我们发现大多数接受前交叉韧带重建的 UFC 格斗运动员至少会重返赛场参加一场比赛；然而，仅有一半以上的运动员至少会重返赛场参加两场比赛。在接受前交叉韧带修复术后重返赛场至少参加 2 场比赛的拳手与对照组拳手在职业生涯长度上没有明显差异。前交叉韧带撕裂后，防守能力显著下降，但进攻能力并未下降。随着职业生涯的发展，所有拳手的胜率都有明显下降，与前交叉韧带损伤无关。

Defensive Performance Declines in Ultimate Fighting Championship Fighters Following Anterior Cruciate Ligament Reconstruction

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 (P < .05 for each). ACLR fighters had significantly lower submission attempts and evasion rates against clinch strikes, ground strikes, and total strikes, postindex (P < .05 for each). Controls had a significantly lower evasion rate against leg strikes, postindex. Both groups’ win percentages significantly declined (ACLR, P = .001; control, P = .012). No significant difference in total career fights was observed (P = .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.
