BACKGROUND
There is limited information about the functional recovery and rate of return to preinjury levels of sports among recreational athletes after anterior cruciate ligament reconstruction (ACLR).
PURPOSE
To investigate the recovery of quadriceps or hamstring strength, assess functional performance, and determine the rate of return to preinjury sports levels among recreational athletes at 1 year after ACLR.
STUDY DESIGN
Cohort study; Level of evidence, 3.
METHODS
A total of 91 recreational-level athletes who underwent anatomic single-bundle ACLR were enrolled. We evaluated the limb symmetry index (LSI) of the quadriceps and hamstring peak torque strength at 60°, in addition to hop test performance (single-leg, triple, crossover, and 6-m timed), patient-reported outcomes, and pre- versus postoperative Tegner activity levels. Outcomes were compared between younger (age <25 years) and older patients (age ≥25 years).
RESULTS
There were 48 patients in the younger group and 43 patients in the older group. At 1-year follow-up, the overall LSIs for quadriceps strength and hamstring strength were 77% and 86%, respectively, and the LSIs of the hop tests were 79% for single-leg, 81% for triple, 84% for crossover, and 85% for 6-m timed hop. Overall, only 24% patients returned to their preinjury Tegner level, and only 8% of patients met the criteria for return to pivoting, cutting, and jumping sports. At 1-year follow-up, the younger group showed significantly more quadriceps strength than the older group (85% vs 64%; = .0001), better single, triple, crossover, and 6-m timed hop test results (85% vs 69%, = .003; 84% vs 75%, = .046; 91% vs. 74%, < .001; and 91% vs 76%, = .003, respectively), higher Lysholm score (87 vs 74; < 0.001) and International Knee Document Committee score (82 vs 66; < .001), and a higher rate of return to preinjury Tegner level (35% vs 12%; = .009).
CONCLUSION
Only 24% of patients returned to the preinjury Tegner level at 1 year after ACLR (35% younger group vs 12% older group; = .009). This information might be helpful in setting realistic expectations for recreational athletes after surgery.
背景
关于前交叉韧带重建（ACLR）后业余运动员功能恢复及恢复到伤前运动水平的比率，相关信息有限。
目的
调查ACLR术后1年时业余运动员股四头肌或腘绳肌力量的恢复情况，评估功能表现，并确定恢复到伤前运动水平的比率。
研究设计
队列研究；证据等级，3级。
方法
共纳入91例接受解剖单束ACLR的业余水平运动员。我们评估了股四头肌和腘绳肌在60°时的峰值扭矩力量的肢体对称指数（LSI），此外还评估了单腿跳、三级跳、交叉跳和6米定时跳测试的表现、患者报告的结果以及术前与术后的Tegner活动水平。对年轻患者（年龄<25岁）和老年患者（年龄≥25岁）的结果进行了比较。
结果
年轻组有48例患者，老年组有43例患者。在1年随访时，股四头肌力量和腘绳肌力量的总体LSI分别为77%和86%，单腿跳测试的LSI为79%，三级跳为81%，交叉跳为84%，6米定时跳为85%。总体而言，只有24%的患者恢复到伤前的Tegner水平，只有8%的患者符合恢复到旋转、急停和跳跃运动的标准。在1年随访时，年轻组的股四头肌力量明显高于老年组（85%对64%；P = 0.0001），单腿跳、三级跳、交叉跳和6米定时跳测试结果更好（分别为85%对69%，P = 0.003；84%对75%，P = 0.046；91%对74%，P < 0.001；91%对76%，P = 0.003），Lysholm评分更高（87对74；P < 0.001）和国际膝关节文献委员会评分更高（82对66；P < 0.001），恢复到伤前Tegner水平的比率更高（35%对12%；P = 0.009）。
结论
ACLR术后1年时，只有24%的患者恢复到伤前Tegner水平（年轻组为35%，老年组为12%；P = 0.009）。这些信息可能有助于为术后的业余运动员设定现实的期望。
