Knocked Knees (Genu Valgum): Causes, Symptoms, and Treatment
In this comprehensive guide, we delve into the world of “Knocked Knees” medically termed “Genu Valgum.” Understanding this common orthopedic condition is crucial as it affects a significant number of individuals. By the end of this article, you’ll have a clear grasp of what causes knocked knees, how to recognize its symptoms and the available treatment options.

Defining Knocked Knees (Genu Valgum)
Knocked knees, clinically known as “Genu Valgum,” refer to a condition where the knees angle inwards, causing the lower legs to bow outwards when a person stands with their feet together. This deviation from the typical alignment of the lower limbs can affect individuals of all ages, from children to adults.
Understanding the Natural Knee Alignment
To appreciate what genu valgum entails, let’s first grasp the natural alignment of the knees. When standing normally, the knees should be close together, with the lower legs perpendicular to the thighs. However, in the case of genu valgum, the knees tend to draw closer while the lower legs flare outward, resembling a “knocked knee” appearance.
Deviation from the Norm
Genu Valgum is considered a deviation from the typical knee alignment. While some degree of genu valgum is normal in children as their bodies develop, excessive or persistent genu valgum can lead to various symptoms and potential complications in both children and adults.
Causes of Knocked Knees:
Understanding the Underlying Causes
To grasp genu valgum fully, it’s essential to explore its root causes, which can vary widely:
1. Genetics:
Genetic factors can play a significant role in predisposing individuals to knocked knees. If you have a family history of genu valgum, you may be more likely to develop it.
2. Growth and Development:
In children, genu valgum often occurs as a part of normal growth and development. It typically peaks between the ages of 2 and 4 and tends to correct itself as the child grows older.
3. Obesity:
Excess body weight, particularly in children, can contribute to the development of genu valgum. The additional weight places increased stress on the knees, affecting their alignment.
4. Medical Conditions:
Certain medical conditions, such as rickets or Blount’s disease, can lead to genu valgum. These conditions affect bone development and can result in abnormal knee alignment.
Common Symptoms:
Recognizing the symptoms of genu valgum is crucial for early intervention and effective management. While some individuals may have mild cases with minimal or no symptoms, others may experience:
1. Knee Pain:
Persistent knee pain, especially around the inner knee, is a common symptom. This discomfort may worsen with physical activity or prolonged standing.
2. Knee Instability:
Genu valgum can lead to instability in the knees, making it challenging to maintain balance and potentially increasing the risk of falls.
3. Gait Abnormalities:
Individuals with genu valgum often exhibit an altered gait, which can involve the knees knocking against each other while walking.
4. Joint Wear and Tear:
Over time, the abnormal alignment of the knees can result in increased wear and tear on the knee joints, potentially leading to osteoarthritis.
5. Cosmetic Concerns:
Many people with genu valgum are concerned about the cosmetic aspect of their condition, as the inward angulation of the knees can be noticeable, affecting self-esteem.
Diagnostic Methods:
If you suspect you or your child has genu valgum or are experiencing any of the mentioned symptoms, it’s essential to seek a professional evaluation. Medical experts typically use the following methods for diagnosis:
1. Physical Examination:
Healthcare providers will conduct a thorough physical examination to assess the degree of genu valgum, including measuring the angle between the knees.
2. X-rays:
X-rays provide detailed images of the knee joint and bone structure, allowing doctors to measure the extent of knee angulation accurately.
3. Medical History:
Your doctor may inquire about your medical history, including family history, to determine any genetic predisposition to genu valgum.
4. Clinical Assessment:
In some cases, doctors may assess gait abnormalities and evaluate how genu valgum affects an individual’s mobility.
Treatment Options:
The treatment of genu valgum depends on several factors, including the age of the individual, the severity of the condition, and the presence of symptoms. Treatment options include:
1. Observation:
In children with mild genu valgum, it is part of normal growth and development, doctors may recommend monitoring the condition as it often corrects itself with time.
2. Orthotic Devices:
Custom-made shoe inserts (orthotics) can help support proper alignment and reduce discomfort, especially in cases where the condition is not severe.
3. Physical Therapy:
Physical therapists can design exercise programs to strengthen the muscles around the knees and improve gait.
4. Bracing:
Some individuals, particularly children, may benefit from wearing knee braces to gradually correct the alignment over time.
5. Surgery:
In severe cases of genu valgum or when conservative treatments are ineffective, surgical intervention may be considered to realign the bones and correct the knee alignment.
Exercises for Genu Valgum:
Exercise plays a pivotal role in managing genu valgum, especially when it’s part of a comprehensive treatment plan. Here are some exercises that can help improve knee alignment:
1. Quadriceps Strengthening:
Exercises that target the quadriceps muscles can help stabilize the knee joint. Leg extensions, squats, and lunges are effective choices.
2. Hamstring Strengthening:
Strong hamstrings can support proper knee alignment. Try exercises like leg curls or bridges.
3. Inner Thigh Strengthening:
Strengthening the inner thigh muscles can help counteract the inward angulation of the knees. Adductor leg lifts and seated leg squeezes are beneficial.
4. Calf Raises:
Strong calf muscles contribute to overall leg stability. Performing calf raises can enhance lower limb strength.
5. Balance and Stability Exercises:
Incorporate balance exercises, such as standing on one leg or using a balance board, to improve stability and prevent falls.
Preventive Measures:
While not all cases of genu valgum can be prevented, especially if genetics are a contributing factor, there are preventive measures that can reduce the risk of severe genu valgum:
1. Maintaining a Healthy Weight:
Encourage weight management through a balanced diet and regular exercise, especially in children.
2. Encouraging Proper Footwear:
Ensure children wear supportive shoes that promote correct alignment.
3. Early Intervention:
If you suspect genu valgum in your child, seek medical evaluation and intervention promptly.
4. Promoting Physical Activity:
Encourage physical activity in children to promote healthy bone development and alignment.
5. Regular Check-Ups:
Schedule regular check-ups with a healthcare provider to monitor your child’s growth and development.
Living with and Recovering from Genu Valgum:
Living with genu valgum may require lifestyle adjustments and a positive outlook:
1. Orthotic Devices:
If prescribed orthotic devices, wear them as recommended to maintain proper alignment.
2. Physical Therapy:
Commit to physical therapy sessions as advised by your healthcare provider to strengthen the muscles around the knees.
3. Supportive Footwear:
Choose comfortable, supportive footwear that complements your treatment plan.
4. Follow Medical Advice:
Adhere to your healthcare provider’s guidance on treatment, exercise, and follow-up appointments.
5. Post-Surgery Recovery:
If surgery is necessary, follow the post-operative care plan diligently and attend all rehabilitation sessions.
6. Support Groups:
Consider joining support groups or seeking counseling, especially if dealing with cosmetic concerns or emotional challenges related to genu valgus.
