At 2 to 3 years after anterior cruciate ligament reconstruction (ACLR), the relationship between known modifiable osteoarthritis (OA) risk factors and recurrent knee injury is unknown. This study aimed to determine the odds of new or recurrent traumatic knee injury in a cohort of young female athletes with ACLR 2 to 3 years postsurgery compared with healthy control participants. Secondary objectives were to explore the relationships of moderate and vigorous physical activity (MVPA) and body mass index (BMI) with knee injury, and to document self-reported MVPA satisfaction and beliefs about OA.
Prospective cohort.
Level 2.
A total of 51 female athletes with unilateral ACLR 1 to 2 years previously and 51 age and sport-matched control participants underwent assessment of MVPA (GT3X accelerometers) and BMI. One year later, participants self-reported knee injuries. Bivariable conditional logistic regression explored the association between knee injury, MVPA, and BMI in each group (injury/control).
At 1-year follow-up (n = 101), 19.6% of the injured cohort and 6.0% of control participants sustained a new or recurrent knee injury. The odds of knee injury for the injury group increased 7-fold over controls [odds ratio (OR) = 7.00 (95% CI = 0.86, 56.90)], although this was not statistically significant. The OR for MVPA was 0.98 (95% CI = 0.93, 1.03) and BMI was OR = 1.24 (95% CI = 0.85, 1.82). Half (56.0%) of injury participants and 66% of controls were satisfied with their MVPA; 81.6% of injury participants believed they had increased knee OA risk compared with someone who had never had a knee injury.
In the 2 to 3 years after ACLR, 1 in 5 young female athletes had a new or recurrent knee injury. Based on the point estimate, injured participants were more likely to suffer a traumatic knee injury than matched control participants. MVPA and BMI were not associated with increased odds of knee injury.
Clinicians should be encouraged to have in-depth conversations with female athletes with previous ACLR regarding enjoyable and sustainable MVPA participation to promote long-term joint health.
在前交叉韧带重建 (ACLR) 后 2 至 3 年，已知可改变的骨关节炎 (OA) 风险因素与复发性膝关节损伤之间的关系尚不清楚。本研究旨在确定接受 ACLR 后 2 至 3 年的年轻女性运动员队列中，新的或复发性创伤性膝关节损伤的可能性与健康对照组参与者相比。次要目标是探讨中度和剧烈体力活动 (MVPA) 和体重指数 (BMI) 与膝关节损伤的关系，并记录自我报告的 MVPA 满意度和对 OA 的信念。
前瞻性队列研究。
2 级。
共有 51 名接受单侧 ACLR 治疗 1 至 2 年的女性运动员和 51 名年龄和运动匹配的对照组参与者接受 MVPA（GT3X 加速度计）和 BMI 的评估。一年后，参与者自我报告膝关节损伤。双变量条件逻辑回归探讨了每组（受伤/对照组）中膝关节损伤、MVPA 和 BMI 之间的关联。
在 1 年随访时（n=101），受伤组中有 19.6%和对照组中有 6.0%的参与者发生新的或复发性膝关节损伤。受伤组发生膝关节损伤的可能性是对照组的 7 倍[比值比 (OR)=7.00（95%CI=0.86,56.90)]，尽管这没有统计学意义。MVPA 的 OR 为 0.98（95%CI=0.93,1.03），BMI 的 OR 为 1.24（95%CI=0.85,1.82）。一半（56.0%）的受伤参与者和 66%的对照组对他们的 MVPA 感到满意；81.6%的受伤参与者认为与从未受过膝关节损伤的人相比，他们患膝关节 OA 风险增加。
在前交叉韧带重建后 2 至 3 年内，1/5 的年轻女性运动员出现新的或复发性膝关节损伤。根据估计值，受伤参与者比匹配的对照组参与者更有可能遭受创伤性膝关节损伤。MVPA 和 BMI 与膝关节损伤的可能性增加无关。
应鼓励有 ACLR 病史的女性运动员进行深入讨论，以进行愉快和可持续的 MVPA 参与，以促进长期关节健康。
