Children's bodies undergo many changes as they grow up. Some of these changes are temporary, while others need to be monitored carefully. One such condition that often worries parents is Knock Knees – a condition where the knees touch while the ankles remain apart. It is common during early childhood. If you notice unusual walking patterns or frequent complaints about pain in the knees, you might need to schedule a knock knees test with a trusted paediatric orthopaedic surgeon in Faridabad.
In this blog, let us explore the types, causes, symptoms and treatment options available for this condition.
What Are Knock Knees?
Knock knees, also known as genu valgum, is a condition in which a child’s knees angle inwards and touch one another when the legs are straightened. While standing, the feet and ankles of the child remain wide apart.
It’s a normal part of a child’s physical development between the ages of 2 and 5. In most cases, the legs gradually straighten out on their own by age 7 or 8. However, if the condition worsens with time or causes discomfort, it may be a sign of knock knees and need medical attention.
When left unaddressed, it can impact how a child walks or runs and even put stress on the hips, ankles, and lower back. That’s why early evaluation by a child bone and joint specialist is key in determining the next steps.
Types of Knock Knees
Not all cases of knock knees are the same. Understanding the type helps doctors decide on the right course of treatment.
- Physiological Knock Knees: This is the most common type seen in young children. It appears around age 2 or 3, peaks by age 4, and usually resolves on its own by age 7 or 8. No treatment is typically needed unless symptoms persist or worsen.
- Pathological Knock Knees: These cases are less common and often linked to an underlying cause of knock knees, such as bone diseases or nutritional deficiencies. Pathological cases do not improve over time and may even become more pronounced without medical intervention.
- Unilateral vs. Bilateral Knock Knees: When only one leg is affected, it’s called unilateral. When both knees angle inward, it’s bilateral. Unilateral knock knees are more concerning and are often a reason to consult a paediatric orthopaedic surgeon in Faridabad for further evaluation.
Common Causes of Knock Knees
Most cases of knock knees is a developmental disease and harmless. But in some instances, an underlying issue is responsible. The most common causes of knock knees in children are:
- Genetics: A family history of knock knees increases the likelihood that a child may experience the same condition.
- Nutritional Deficiencies: Lack of vitamin D and calcium can lead to rickets, which weakens the bones and causes them to bend abnormally.
- Childhood Obesity: Excess weight puts added pressure on the growing legs, worsening the angle of the knees.
- Bone Injuries or Infections: Fractures or infections that affect the growth plates in the knees can lead to improper bone development.
- Improper Growth Patterns: Sometimes, the bones don’t grow at the same rate, leading to misalignment that results in knock knees.
Identifying the cause of knock knees early on can help determine whether the condition is temporary or needs medical treatment. For timely consultation, approach a paediatric orthopaedics hospital in Faridabad to get some clarity on the condition and peace of mind.
Symptoms of Knock Knees Condition
Many parents first notice knock knees during when the child is engaged in regular play or walking. While some signs are subtle, others may interfere with daily activities. Watch out for the following symptoms:
- Visible knee gap: The knees touch and the ankles remain apart while standing straight, causing a visible knee gap.
- Walking difficulties: Your child may walk with a waddle, limp, or awkward gait.
- Knee or hip pain: Discomfort during or after physical activity.
- Trouble running or playing sports: Limited mobility or frequent tripping.
- Uneven shoe wear: Shoes wearing out more on one side due to misalignment.
Diagnosis of Knock Knees
Doctors conduct a thorough evaluation to determine the severity and root cause of knock knees. A knock knees test typically involves:
- Physical examination: The doctor checks leg alignment, walking patterns, and joint movement.
- Measurement of knee-to-ankle gap: This helps quantify the angle and distance between knees and ankles.
- X-rays and imaging tests: To assess bone development, growth plates, and any underlying issues.
- Blood tests: In some cases, to check for nutritional deficiencies like low vitamin D or calcium.
When Should Parents Be Concerned?
It’s natural for parents to wonder when knock knees stops being “normal” and starts becoming a medical concern. While most cases correct themselves with age, there are a few red flags to look out for:
- Persistent deformity beyond age 7–8
- One-sided knock knees (unilateral)
- Pain in knees, hips, or legs
- Difficulty walking, running, or standing for long
- Progressively worsening leg angle
If any of these signs are present, it’s time to consult a paediatric orthopaedic surgeon in Faridabad. Early intervention not only prevents complications but also improves your child’s mobility and confidence.
Treatment of Knock Knees in Children
The treatment of knock knees depends on your child’s age, symptoms and the severity of the disease. Most mild cases resolve naturally, but persistent or pathological cases need more targeted care:
- Observation and Monitoring: Physiological cases are usually monitored every 6–12 months to track improvement.
- Nutritional Support: Addressing vitamin D and calcium deficiencies can prevent bone weakening.
- Bracing: In younger children, braces or orthotic shoes may help align the legs correctly.
- Surgical Intervention: In severe or non-responsive cases, procedures like guided growth surgery or osteotomy may be recommended. These surgeries aim to correct bone alignment and support long-term joint health.
