During four academic years (1974-1978) at a major university, 51 of 70 knee injuries sustained by football players were Grade I or II sprains of the medial collateral ligament of the knee. All were managed identically with an active rehabilitation program involving partial or no immobilization. Players with Grade I sprains returned to full, unprotected participation after an average of 10.6 days of time loss; those with Grade II sprains returned after 19.5 days. Neither group showed an appreciably increased likelihood of reinjury. The likelihood of sustaining any knee injury was more than three times greater during spring as opposed to fall football.
在一所主要大学的四个学年（1974 - 1978年）期间，70名足球运动员膝盖受伤，其中51例为膝关节内侧副韧带I级或II级扭伤。所有病例均采用相同的积极康复方案，包括部分固定或不固定。I级扭伤的运动员平均损失10.6天后恢复到完全不受保护的比赛状态；II级扭伤的运动员在19.5天后恢复。两组再次受伤的可能性均未明显增加。与秋季足球赛相比，春季足球赛中膝盖受伤的可能性要高出三倍多。
