Abstract

Context: 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. Objective: To determine the impact of knee injury history on HRQOL in adolescent athletes who were medically cleared for full participation. Design: Cross-sectional. Setting: Athletic training clinics. Participants: 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). Interventions: Participants completed the Pediatric International Knee Documentation Committee form and Pediatric Quality of Life Inventory during their preparticipation examination. Main Outcome Measures: 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. Results: 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], NOHIS = 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). Conclusions: 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.
