The knee and ankle are among the most commonly injured joints in the body. Long-term strength and neuromuscular control deficits are common following these injuries, yielding lifelong disability and poor quality of life. However, it is unknown how the number of injuries sustained influences quality of life.
Determine the association between the number of ankle or knee injuries sustained and physical and mental quality of life.
A total of 806 ankle-injured (age:45.2 ± 15.3 yrs; body mass index [BMI]:28.6 ± 7.4 kg/m), 658 knee-injured (age:49.3 ± 16.1 yrs; BMI:28.4 ± 7.4 kg/m), and 996 uninjured (age:43.4 ± 16.1 yrs; BMI:26.9 ± 6.5 kg/m) adults completed the SF-8 survey to determine the physical (PCS) and mental (MCS) contributions to quality of life. Respondents were categorized by injury history (ankle, knee, none) and number of injuries (0, 1, 2, or 3 or more [3+]) to the same joint. Backward linear regression models were used to determine the association between quality of life, age, and injury history separately for SF-8 PCS and MCS, as well as ankle versus knee injury.
Reporting 1, 2, or 3+ ankle injuries along with age predicted SF-8 PCS (P < 0.001). Further, 1 or 2 ankle injuries and age (P < 0.001) predicted SF-8 MCS. Reporting 1, 2, or 3+ knee injuries along with age significantly predicted SF-8 PCS (P < 0.001). Age, but not knee injury history, significantly predicted SF-8 MCS (P < 0.001).
Current age and history of sustaining at least one injury negatively impact physical quality of life following either a knee or ankle injury. However, mental quality of life was predicted most consistently by age. Efforts to reduce injuries should be employed to improve quality of life, but more research is needed to determine what other factors contribute to quality of life across the lifespan.
膝盖和脚踝是身体中最常受伤的关节。这些损伤后长期的力量和神经肌肉控制缺陷很常见，会导致终身残疾和生活质量低下。然而，尚不清楚受伤次数如何影响生活质量。
确定脚踝或膝盖受伤次数与身体和心理健康生活质量之间的关联。
共有806名脚踝受伤者（年龄：45.2±15.3岁；体重指数[BMI]：28.6±7.4kg/m²）、658名膝盖受伤者（年龄：49.3±16.1岁；BMI：28.4±7.4kg/m²）和996名未受伤者（年龄：43.4±16.1岁；BMI：26.9±6.5kg/m²）完成了SF-8调查问卷，以确定身体（PCS）和心理（MCS）对生活质量的影响。受访者按受伤史（脚踝、膝盖、无）和同一关节的受伤次数（0、1、2或3次及以上[3+]）进行分类。采用向后线性回归模型分别确定SF-8 PCS和MCS以及脚踝与膝盖损伤中生活质量、年龄和受伤史之间的关联。
报告1次、2次或3次及以上脚踝损伤以及年龄可预测SF-8 PCS（P<0.001）。此外，1次或2次脚踝损伤以及年龄（P<0.001）可预测SF-8 MCS。报告1次、2次或3次及以上膝盖损伤以及年龄可显著预测SF-8 PCS（P<0.001）。年龄而非膝盖受伤史可显著预测SF-8 MCS（P<0.001）。
当前年龄和至少受过一次伤的病史会对膝盖或脚踝受伤后的身体生活质量产生负面影响。然而，心理健康生活质量最一致地由年龄预测。应努力减少受伤以改善生活质量，但需要更多研究来确定在整个生命周期中还有哪些其他因素会影响生活质量。
