Can children and teenagers tear their MCL, and is it treated differently?

Why growing knees are different

The MCL attaches above and below the knee close to the growth plates, the areas of softer cartilage where bones lengthen. In children, the ligament can be stronger than the growth plate, so a blow to the outside of the knee may separate the growth plate rather than tear the ligament. Both cause pain on the inner side, but they are treated differently.

Signs that need prompt assessment

• Tenderness over the bone just above or just below the knee rather than along the joint line
• Swelling around the lower thigh
• Inability to bear weight or a marked limp
• The leg looks angled or the knee looks deformed
• Rapid swelling inside the joint, which in teenagers can mean an ACL tear or a kneecap dislocation

How it is treated

An isolated MCL sprain in a teenager is treated with protection in a hinged brace, early movement and a structured rehabilitation programme, as in adults, and most heal well. A growth plate fracture may need a cast or brace with closer X-ray follow-up, and occasionally surgery if displaced. Careful follow-up ensures the leg continues to grow normally.

Returning to sport and school

Young players often feel ready before the ligament has fully healed. A return based on strength, balance and sport-specific tests, rather than pain alone, reduces repeat injuries. At Aman Hospital in Doha, Dr. Gelber examines the child, reviews X-rays and works with families and coaches on a safe return.
