Osteoarthritis living in children

Overview

Osteoarthritis (say: os-tee-oh-arth-ry-tis) is a condition where the cartilage that cushions the ends of bones wears down over time. In children, this is very rare and is almost always caused by another health problem, such as a joint injury, a hip problem present at birth, or other conditions that affect the joints.

No, osteoarthritis is not common in children. Most cases of arthritis in young people are a different type called 'juvenile idiopathic arthritis' (JIA). Osteoarthritis in children is rare and usually happens because of another medical issue.

Osteoarthritis can affect children of any age, but it is more likely to occur in those who have had a serious joint injury, a hip problem (like hip dysplasia) that was not treated, or conditions such as hemophilia or certain metabolic disorders.

Symptoms

Common symptoms

• Joint pain, especially after activity
• Stiffness in the joint, often after periods of rest
• Swelling around the joint
• A grating or grinding feeling when moving the joint

Symptoms in children

• Children may not complain of pain directly but might limp or avoid using the affected limb.
• They may have trouble keeping up with friends during sports or play.
• The joint may feel warm to the touch.
• You might notice changes in how they walk or move.

Symptoms in older adults

• More constant pain, even at rest
• Morning stiffness that lasts less than 30 minutes
• Joint crepitus (cracking or popping sounds)
• Bony swellings at the finger joints (Heberden's or Bouchard's nodes)

Causes

Main causes

• Previous joint injury (fracture or dislocation) that damaged the cartilage
• Abnormal joint development from birth (like hip dysplasia)
• Conditions such as hemophilia (bleeding into joints) or metabolic disorders
• Other diseases that affect the joint, such as infection or inflammation

Risk factors

• Being overweight, which puts extra stress on joints
• Participation in high-impact sports without proper training or equipment
• A family history of early osteoarthritis

When to see a doctor

See a doctor urgently if:

• If your child has sudden joint pain with swelling, redness, or fever
• If they cannot move a joint normally or bear weight on it

Book a routine appointment if:

• If your child has joint pain that lasts more than a few weeks
• If they start limping or avoiding activities they used to enjoy
• If there is any new swelling or stiffness in a joint

Diagnosis

A doctor will take a detailed history, ask about symptoms and any past injuries, and perform a physical exam. They may also order tests to look at the joint and rule out other conditions.

Tests that may be done

• X-rays of the affected joint can show signs of cartilage loss or bone changes.
• Blood tests to check for inflammation or other medical problems.
• Sometimes an MRI scan is needed to get a clearer picture of the cartilage and soft tissues.

What to expect at your appointment

The doctor will explain what they find and discuss whether the changes seen are likely to affect your child's daily life. They will talk about ways to manage pain and keep your child active, and may refer you to a specialist such as a pediatric rheumatologist or orthopedic surgeon.

Treatment

Treatment for osteoarthritis in children focuses on relieving symptoms, improving joint function, and addressing any underlying cause. The goal is to help the child stay active and avoid long-term disability.

Self-care at home

• Encourage gentle activity like swimming or cycling to keep joints moving without heavy impact.
• Apply heat packs or warm baths to relax stiff joints.
• Use cold packs for 15-20 minutes after activity if the joint is sore or swollen.
• Make sure your child maintains a healthy weight to reduce stress on joints.

Medical treatments

Doctors may suggest pain relief such as acetaminophen (paracetamol) or anti-inflammatory medications (like ibuprofen) for short periods. They might also recommend physical therapy to strengthen muscles around the joint, use of braces or shoe inserts to support the joint, or injections into the joint to reduce inflammation. Always follow your doctor's advice on which treatments are safe for your child.

When is surgery considered?

Surgery is rarely needed in children with osteoarthritis. It may be considered if the joint is very damaged, the child has severe pain that limits daily activities, and other treatments have not helped. Options include joint realignment or, in very severe cases, joint replacement, but this is unusual in childhood.

Living with this condition

Children with osteoarthritis can still enjoy school, play, and hobbies. The key is to find a balance between staying active and not overloading the joint. Talk to your child's school about any needed help, like extra time to get between classes or alternative sports activities.

Lifestyle tips

• Encourage low-impact exercises like swimming, cycling, and walking.
• Help your child learn to listen to their body and take breaks when needed.
• Make sure they wear proper shoes and use any recommended braces or supports.
• Foster a positive attitude and focus on what they can do, not on limitations.

Diet and exercise

A balanced diet rich in fruits, vegetables, whole grains, and lean protein supports overall health. There is no special diet that cures osteoarthritis, but maintaining a healthy weight is important. Staying physically active helps keep joints flexible and muscles strong.

Mental health and emotional wellbeing

Living with chronic pain can be frustrating for a child. They may feel left out when they cannot keep up with friends. It is important to talk openly about feelings and to reassure them that it is okay to ask for help. If you notice signs of depression or anxiety, speak to your doctor or a mental health professional.

Prevention

In most cases, osteoarthritis in children cannot be completely prevented, especially when it is due to an underlying condition. However, you can reduce the risk by protecting against joint injuries (e.g., using proper safety gear in sports), keeping a healthy weight, and treating any underlying conditions early.

Vaccines

Not applicable for osteoarthritis itself, but ensuring your child is up-to-date with vaccinations can help prevent infections that might affect joints.

Screening programmes

There is no routine screening for osteoarthritis in children. If your child has risk factors (like a previous joint injury or a family history), your doctor may monitor their joints more closely.

Complications

If left untreated

• Persistent pain that interferes with daily activities and sleep
• Limited joint movement and stiffness
• Muscle weakness around the joint
• Difficulty walking or performing tasks
• Long-term damage to the joint surface

Long-term outlook

With early diagnosis and proper management, most children with osteoarthritis can lead full, active lives. Treatment can help control pain, maintain joint function, and prevent further damage. The outcome depends on the underlying cause, but many children improve and require only simple treatments.
