Ligament sprains are common injuries in athletes, but they occur less frequently in younger children because their ligaments are more elastic. In children, the “weak link” tends to be the nearby growth plates (epiphyseal plates), which are more susceptible to injury than the ligaments themselves. However, as adolescents enter their growth spurt, they become more prone to ligament sprains due to rapid changes in their bones and muscles.
In any young athlete who presents with what seems to be a ligament injury, doctors will carefully assess whether a nondisplaced growth plate (physeal) fracture could be the real issue. Stress radiographs (special X-rays) can help determine whether the injury involves the ligaments or the growth plates.
Treatment:
- Mild Sprains (Low-Grade): These can usually be managed with ice and rest. If no instability is found during a physical exam, the athlete can gradually start walking or moving based on their pain levels.
- Moderate to Severe Sprains: If ligament laxity (looseness) is noted, a more prolonged period of splinting or limited weight-bearing may be required. Some ligaments, like the ACL, don’t heal well with rest alone. In near-mature adolescents aiming to return to competitive sports, surgical reconstruction may be necessary.
Case Example:
14-year-old Sarah, a promising soccer player, twisted her knee during a game. Her doctor initially suspected a ligament sprain, but an X-ray revealed a subtle growth plate injury. With a combination of rest, ice, and a brace, Sarah avoided surgery. After a few weeks, she was back on the field, stronger than ever.
