The medical term for knock knees is genu valgum, which refers to the condition in which a person’s knees come into contact or come close together, but their ankles stay separate. This alignment may be a source of anxiety for many people, both from an aesthetic and a practical one. The fact that knock knees can be fixed is a piece of good news.
Let’s get straight to the point.
Knock knees (genu valgum) occur when the knees come together while the ankles remain apart. It can be caused by genetics, injury, nutritional deficiencies (like vitamin D or calcium), or underlying conditions like obesity or rickets.
Treatment options include braces, exercises, weight management, and in severe cases, surgery. Prevention focuses on early detection through regular check-ups, a balanced diet with key nutrients, avoiding injury, and proper training for physical activities.
Addressing the condition early and maintaining good nutrition and safety practices can help prevent or manage knock knees effectively.
What Causes Knock Knees?
Understanding the root causes of knock knees is crucial for effective intervention and management. Here’s a more detailed look at the primary causes:
1. Genetics
- Inherited Traits: Just as we inherit eye colour, height, and other physical attributes from our parents, the alignment of our legs can also be a genetic trait. If one or both parents had knock knees as children, there’s a higher likelihood their offspring might develop the condition.
- Genetic Disorders: Some genetic disorders can affect bone growth and alignment, leading to knock knees. For instance, conditions like Down syndrome have been associated with a higher prevalence of knock knees.
2. Injury
- Traumatic Events: A severe blow or trauma to the knee, especially during the crucial growth years in childhood, can disrupt the natural alignment of the leg. This can result in the development or exacerbation of knock knees.
- Repetitive Stress: Activities that put continuous stress on the knees, like certain sports, can also contribute to the condition if not balanced with proper training and rest.
3. Nutritional Deficiencies
- Vitamin D Deficiency: Vitamin D plays a pivotal role in bone health. A deficiency can lead to weakened bones and conditions like rickets, which is a significant cause of knock knees in children.
- Calcium Deficiency: Calcium is essential for bone strength and density. A lack of adequate calcium in the diet can lead to softer bones that are more prone to misalignment.
- Balanced Nutrition: Apart from Vitamin D and calcium, other nutrients like phosphorus and magnesium also play a role in bone health. A balanced diet is crucial for preventing conditions like knocked knees.
4. Underlying Medical Conditions
- Rickets: This is a bone disorder caused by a deficiency of vitamin D, calcium, or phosphate. Children with rickets often display signs of knock knees due to weakened bones.
- Obesity: Excessive weight puts added stress on the knees. Over time, this can lead to misalignment, especially in children whose bones are still growing and shaping.
- Bone Infections or Tumors: In rare cases, infections or tumours in the leg bones can lead to knock knees. These conditions can weaken the bone structure, leading to misalignment.
How to Correct Knock Knees
Addressing knock knees requires a combination of medical intervention and lifestyle changes. Here’s an in-depth look at the primary corrective measures:
1. Braces or Orthotic Therapy
- Purpose of Braces: Braces are designed to provide external support to the knees, helping them gradually move towards a more natural alignment. They work by applying consistent pressure in specific areas to guide the knees.
- Types of Braces: There are various braces available, from simple knee straps to more complex full-leg braces. The choice depends on the severity of the condition and the individual’s age.
- Duration of Use: The duration for which one needs to wear a brace varies. A few months might suffice for mild cases, while severe cases might require years. Regular check-ups with an orthopedic specialist are essential to monitor progress.
2. Exercises and Stretches
- Physical Therapy: Engaging in physical therapy can be highly beneficial. A trained therapist can guide individuals through specific exercises tailored to their needs.
- Leg Strengthening Exercises: Focusing on muscles like the quadriceps, hamstrings, and calves can provide better support to the knees. Exercises such as squats, lunges, and calf raises can be beneficial.
- Hip Strengthening Exercises: Strengthening the hip muscles, especially the hip abductors, can help in providing better alignment for the knees. Clamshells and side leg raises are examples of such exercises.
- Stretches: Stretching the inner thighs, hamstrings, and calves can help reduce tension and improve flexibility. This can assist in realigning the knees over time.
3. Weight Management
- Impact of Obesity: Excessive weight puts added stress on the knees, exacerbating the knock knee condition. The additional pressure can hinder natural alignment, especially in growing children.
- Dietary Changes: Adopting a balanced diet focusing on whole foods, lean proteins, and plenty of vegetables can aid in weight loss.
- Regular Exercise: Engaging in low-impact exercises like swimming, cycling, or walking can help in weight management without putting undue stress on the knees.
4. Surgery
- When is Surgery Needed? Surgery is typically considered a last resort, reserved for severe cases or when other treatments haven’t been effective. It’s more commonly recommended for adults, as their bones are fully grown.
- Types of Surgical Procedures: There are various surgical methods, such as osteotomy, where the bone is cut and realigned, or guided growth surgery for children, where plates are used to guide the growth of the bone.
- Recovery: Post-surgery, a period of rehabilitation is essential. This involves physical therapy, rest, and sometimes the use of braces or casts to support the newly aligned knees.
Prevention is Better Than Cure
While treatments for knock knees are available, preventing the condition or its exacerbation is always the preferred approach. Here’s an in-depth look at the primary preventive measures:
1. Regular Check-ups
- Importance of Early Detection: Detecting knock knees in its early stages can lead to more effective interventions. The sooner the condition is identified, the better the chances of managing or even reversing it without invasive treatments.
- Pediatric Assessments: Regular pediatric check-ups are crucial, especially during the growth spurts of childhood. Pediatricians can monitor leg alignment and recommend interventions if they notice any abnormalities.
- Growth Chart Monitoring: Tracking a child’s growth, including leg alignment, can provide valuable insights. Any sudden changes or deviations from the norm can be early indicators of conditions like knock knees.
2. Balanced Diet
- Role of Nutrition: Proper nutrition plays a pivotal role in bone health and alignment. Ensuring a diet rich in essential nutrients can prevent conditions that lead to knock knees.
- Vitamin D and Calcium: These are the building blocks of bone health. Sources of vitamin D include sunlight, fortified foods, and supplements. Calcium can be found in dairy products, green leafy vegetables, and fortified foods.
- Other Essential Nutrients: Apart from Vitamin D and calcium, other nutrients like phosphorus, magnesium, and vitamin K also play a role in bone health. Incorporating a variety of foods into the diet ensures that children receive all the necessary nutrients for healthy bone growth.
3. Avoiding Injury
- Protective Gear: If children are involved in sports or activities with a risk of falls or collisions, ensuring they wear the appropriate protective gear, like knee pads, can prevent injuries that might lead to knocked knees.
- Safe Play Environments: Ensuring that play areas are free from hazards can reduce the risk of injuries. This includes checking for uneven surfaces, sharp objects, or any other potential dangers.
- Proper Training: For children involved in sports, proper training and warm-ups are essential. Coaches and trainers should teach the right techniques to prevent undue stress on the knees. Additionally, ensuring that children don’t overtrain and have adequate rest periods can prevent repetitive stress injuries.
Prevention is a holistic approach that involves regular monitoring, a balanced diet, and safety measures. While genetics and certain conditions might predispose some individuals to knock knees, these preventive steps can go a long way in ensuring the condition doesn’t worsen or even develop in the first place.
Conclusion
Even though they are rather common, knock knees are something that many people worry about. Nevertheless, it is possible to fix the alignment and lead a healthy, active life with the assistance of the appropriate therapies. It is critical to discuss your concerns with a trained medical practitioner in order to decide the most appropriate treatment for you or your kid if you believe that you or they have knock knees.
