I analyzed insurance claims for injuries sustained in high-school football over a three-year period in six western states. Nineteen and one-half per cent of the players sustained at least one injury per season, of which 12.7 per cent were knee injuries. Follow-up questionnaires completed by 529 (81 per cent) of the injured players showed that 394 had been diagnosed as having ligament injuries; eighty-eight, internal derangement of the knee; and forty-seven, patellar injuries. Twenty-six per cent of the patients with ligament injuries had further injury to the involved knee. Fifty-nine per cent of the patients with internal derangement of the knee had subsequent injury to the same knee. Eighty-seven per cent of the patients with patellar injuries had a subsequent injury to the involved knee and an increased incidence (34 per cent) of injury to the contralateral knee.
我分析了六个西部州三年期间高中橄榄球运动员受伤的保险理赔情况。19.5%的球员每个赛季至少受伤一次，其中12.7%是膝盖受伤。529名（81%）受伤球员填写的后续调查问卷显示，394人被诊断为韧带损伤；88人是膝关节内部紊乱；47人是髌骨损伤。26%的韧带损伤患者受伤的膝盖再次受伤。59%的膝关节内部紊乱患者同一膝盖随后再次受伤。87%的髌骨损伤患者受伤的膝盖随后再次受伤，对侧膝盖受伤的发生率也有所增加（34%）。
