Current evidence suggests that, despite returning to full participation, physically active adults with a previous knee injury experience lower health-related quality of life (HRQOL) than those with no knee injury history. It is unknown if this relationship is present in adolescent athletes.
To determine the impact of knee injury history on HRQOL in adolescent athletes who were medically cleared for full participation.
Cross-sectional.
Athletic training clinics.
A convenience sample of 183 adolescent athletes, who were medically cleared for full participation, were grouped by self-report of a previous knee injury: positive knee injury history (HIS; n = 36, age = 15.7 [1.4] y, height = 168.0 [11.9] cm, and weight = 71.8 [11.9] kg) and no knee injury history (NO-HIS; n = 147, age = 15.5 [1.4] y, height = 166.0 [10.5] cm, and weight = 67.6 [14.6] kg).
Participants completed the Pediatric International Knee Documentation Committee form and Pediatric Quality of Life Inventory during their preparticipation examination.
Generalized linear models were used to compare group differences for the total and subscale scores of the Pediatric International Knee Documentation Committee and Pediatric Quality of Life Inventory.
Main effects of injury group indicated that the HIS group reported significantly lower scores than the NO-HIS group for the Pediatric International Knee Documentation Committee total score (P < .001; HIS = 79.2 [21.7], NO-HIS = 95.8 [8.6]) and for the Pediatric Quality of Life Inventory total (P = .001; HIS = 85.7 [10.9], NO-HIS = 90.9 [7.3]), physical functioning (P = .002; HIS = 86.7 [13.6], NO-HIS = 92.1 [8.2]), school functioning (P = .01; HIS = 80.6 [12.4], NO-HIS = 86.8 [12.2]), and social functioning (P = .01; HIS = 89.3 [12.4], NO-HIS = 94.6 [8.9]) scores. No group differences were reported for the emotional functioning subscale (P = .13; HIS = 85.7 [17.7], NO-HIS = 89.7 [13.1]). No interactions or main effects of sex were reported (P > .05).
Our findings suggest that, despite returning to full sport participation, adolescent athletes with a previous knee injury generally experience lower HRQOL than their peers with no knee injury history, specifically for knee-specific HRQOL, physical functioning, school functioning, and social functioning. Our results are similar to previous findings reported in college athletes and military cadets.
目前的证据表明，尽管已恢复全面参与运动，但曾有过膝关节损伤的身体活跃的成年人，其与健康相关的生活质量（HRQOL）低于无膝关节损伤史的成年人。尚不清楚这种关系在青少年运动员中是否存在。
确定膝关节损伤史对经医学检查允许全面参与运动的青少年运动员健康相关生活质量的影响。
横断面研究。
运动训练诊所。
选取183名经医学检查允许全面参与运动的青少年运动员作为便利样本，根据其膝关节损伤自我报告进行分组：膝关节损伤史阳性组（HIS；n = 36，年龄 = 15.7 [1.4]岁，身高 = 168.0 [11.9]厘米，体重 = 71.8 [11.9]千克）和无膝关节损伤史组（NO - HIS；n = 147，年龄 = 15.5 [1.4]岁，身高 = 166.0 [10.5]厘米，体重 = 67.6 [14.6]千克）。
参与者在参与前检查期间完成了儿科国际膝关节文献委员会表格和儿童生活质量量表。
使用广义线性模型比较儿科国际膝关节文献委员会和儿童生活质量量表总分及各子量表得分的组间差异。
损伤组的主要效应表明，HIS组在儿科国际膝关节文献委员会总分（P <.001；HIS = 79.2 [21.7]，NO - HIS = 95.8 [8.６]）、儿童生活质量量表总分（P = 0.001；HIS = 85.7 [10.9]，NO - HIS = 90.9 [7.3]）、身体功能（P = 0.002；HIS = 86．7 [13.6]，NO - HIS = 92.1 [8.2]）、学校功能（P = 0.01；HIS = 80.6 [12.4]，NO - HIS = 86.8 [12.2]）和社会功能（P = 0.01；HIS = 89.3 [12.4]，NO - HIS = 94.6 [8.9]）得分方面显著低于NO - HIS组。情感功能子量表未报告组间差异（P = 0.13；HIS = 85.7 [17.7]，NO - HIS = 89.7 [13.1]）。未报告性别间的交互作用或主要效应（P > .05）。
我们的研究结果表明，尽管已恢复全面的体育参与，但曾有过膝关节损伤的青少年运动员，其健康相关生活质量总体低于无膝关节损伤史的同龄人，特别是在特定于膝关节的健康相关生活质量、身体功能、学校功能和社会功能方面。我们的结果与先前在大学生运动员和军校学员中报告的结果相似。
