Pediatric Sports Injuries: A Parent’s Guide

Sport is a wonderful part of childhood — building fitness, coordination, and confidence. But growing bodies are vulnerable to injuries that differ from those in adults, and knowing how pediatric sports injuries happen helps keep young athletes active and safe. Dr Masci assesses and treats pediatric sports injuries at his London clinics, with one-stop ultrasound and rapid access to imaging. This guide explains the common injuries, how they’re treated, and how to prevent them — and links to a guide for each specific condition.

Why are children more vulnerable to sports injuries?

Children’s bones, muscles, and tendons are still developing. Their growth plates — areas of cartilage near the ends of long bones — are weaker than the surrounding ligaments and tendons. So an injury that would merely sprain an adult can cause a growth plate fracture in a child.

Repetitive training strain, growth spurts, and poor biomechanics also drive overuse injuries — common in football, gymnastics, athletics, swimming, and tennis.

Common pediatric sports injuries

Growth plate (physeal) fractures

The growth plate is the most common site of injury in children, typically at the wrist, ankle, or knee, from falls, twisting, or repetitive stress. Prompt assessment matters because a severe injury can affect future bone growth.

Apophyseal injuries (apophysitis)

Apophyses are growth areas where tendons attach to bone. Repetitive traction inflames them, especially during growth spurts. Examples include Osgood-Schlatter disease (knee), Sever’s disease (heel), hip apophysitis, and Sinding-Larsen-Johansson syndrome (kneecap).

Stress fractures

Repetitive-impact sports — running, gymnastics, football — can cause microscopic cracks in bone, with pain that worsens on activity and eases with rest. A common example in young athletes is a pars stress fracture of the lumbar spine. Our stress fracture management guide explains the principles.

Ligament and tendon injuries

Children injure growth plates more readily than ligaments, but older adolescents can develop adult-type sprains and tendon strains, especially around the ankle and knee.

Shoulder and elbow overuse injuries

Throwing and racquet sports — cricket, baseball, tennis — strain the growing shoulder (Little League shoulder) and elbow (Little League elbow / OCD of the elbow), inflaming the growth cartilage.

How are pediatric sports injuries assessed?

Symptoms vary but often include pain, swelling, reduced movement, and limping or avoiding activity. With growth plate injuries, the pain is usually well localised, and the child may be unable to bear weight. Dr Masci performs a detailed assessment — checking swelling, tenderness, joint stability, and range of motion — and uses the injury mechanism and the child’s sporting background to tell an acute injury from an overuse one.

Imaging is central to diagnosing pediatric sports injuries: X-ray, ultrasound, and MRI each have a role, with ultrasound and MRI avoiding radiation where possible — an important consideration in children.

How are pediatric sports injuries treated?

Treatment depends on the type and severity. For overuse injuries, rest and activity modification come first, with physiotherapy restoring strength, balance, and flexibility. A gradual, structured return to sport prevents recurrence.

Reassurance and education matter as much as the treatment — recovery can take weeks to months, depending on the injury and the child’s age, and most young athletes make a full recovery. Injection therapy such as PRP is used only occasionally, and only in older adolescents with persistent tendon injuries — children and younger teenagers are managed without it.

How can you prevent pediatric sports injuries?

Several simple steps lower the risk:

• Warm up and prepare properly before training

• Focus on good technique and avoid excessive repetitive movements

• Encourage variety — children who play several sports get fewer overuse injuries than those who specialise early

• Support recovery with good nutrition, hydration, and adequate rest

• Act on early pain or fatigue rather than pushing through it

That last point is the most important: a young athlete’s pain is a signal to assess, not to push through.

Frequently asked questions about pediatric sports injuries.s

Are growth plate injuries serious?

They can be, which is why prompt assessment matters. Most heal completely, but a missed or severe growth plate fracture can affect future bone growth — so persistent pain near a joint in a child should always be checked rather than dismissed as “growing pains”.

What is the difference between a growth plate injury and growing pains?

Genuine growing pains are typically vague, affect both legs, and ease quickly. An injury usually causes localised pain over one spot, worsens with a specific activity, and may come with swelling or a limp. When in doubt, have it assessed — the distinction matters.

Should my child rest completely or keep playing?

It depends on the injury. Many overuse injuries need a period of relative rest and load reduction rather than complete inactivity, with cross-training to stay fit. A growth plate injury may need more protection. A sports doctor can set the right level so your child stays as active as is safe.

When should I take my child to see a doctor?

See a doctor if pain persists beyond a week or two, causes a limp, limits movement, or comes with swelling — or if your child keeps avoiding an activity they normally enjoy. Early, accurate diagnosis is the fastest route back to sport and protects the growing skeleton.

Can children have injections like adults?

Rarely. We avoid injections in growing children wherever possible, reserving options like PRP for older adolescents with stubborn tendon problems. Most pediatric injuries are managed with rest, physiotherapy, and time.

Final word from Sport Doctor London about pediatric sports injuries

Pediatric sports injuries differ from adult ones because the growing skeleton has its own weak points — growth plates and apophyses. Most settle well with rest, physiotherapy, and a graded return to sport, and the priority is always protecting future growth. If your child has pain that won’t settle, an early assessment gives peace of mind and the right plan.
