Ligament injuries in the knees of children.

Injuries of the medial collateral ligament in children are rarely reported. We are describing six tears of the medial collateral ligament in which an operative repair was done. The patients' ages were six to eleven years. Five were boys and one, a girl. The follow-up (seven months to thirteen years) showed normal results in three; good, in two; and fair, in one. Three patients also had had an injury to the anterior cruciate ligament or an avulsion injury to the anterior tibial spine.
