What Is Genu Valgum

Genu valgum, often referred to as “knock-knees,” is a condition where a person’s knees bend inward when they stand or walk. This article aims to provide a simple and easy-to-understand explanation of genu valgum, including its types, causes, symptoms, diagnostic tests, treatments, and medications.

Types of Genu Valgum:

1. Physiologic Genu Valgum: This is a normal variation in children where the knees naturally bend inward during growth, typically between ages 2 to 4.
2. Pathologic Genu Valgum: This type occurs due to an underlying medical condition and is not part of normal growth.

Causes of Genu Valgum 

1. Genetics: Sometimes, genu valgum can run in families.
2. Rickets: A lack of vitamin D and calcium can weaken bones and lead to genu valgum.
3. Obesity: Excess weight can put pressure on the knees and cause them to bend inward.
4. Injury: Trauma to the leg or knee can lead to knock-knees.
5. Arthritis: Certain types of arthritis can affect the knee joint and cause genu valgum.
6. Bone Diseases: Conditions like Paget’s disease can disrupt normal bone development.
7. Metabolic Disorders: Some metabolic disorders can affect bone growth.
8. Neurological Disorders: Conditions that affect the nerves controlling leg muscles can lead to knock-knees.
9. Infection: Bone infections can interfere with proper bone growth.
10. Muscle Imbalances: Weak or imbalanced leg muscles can contribute to the condition.
11. Leg-Length Discrepancy: When one leg is shorter than the other, it can result in genu valgum.
12. Overuse: Repetitive stress on the knees, like in sports, can lead to knock-knees.
13. Ligament Injuries: Damage to knee ligaments can affect joint stability.
14. Hormonal Changes: Imbalances in hormones can impact bone growth.
15. Tumors: Bone tumors can disrupt normal bone development.
16. Connective Tissue Disorders: Conditions like Ehlers-Danlos syndrome can affect joint stability.
17. Osteoporosis: Weak, brittle bones are more prone to deformities like genu valgum.
18. Congenital Conditions: Some individuals are born with knee deformities.
19. Malnutrition: A lack of essential nutrients can hinder proper bone growth.
20. Idiopathic: In some cases, the exact cause remains unknown.

20. Self-Esteem Issues: Psychological impact due to altered appearance.

Diagnostic Tests for Genu Valgum 

1. Physical Examination: A doctor will visually assess the knee alignment.
2. X-rays: Images of the knees to determine the degree of deformity.
3. CT Scan: Detailed images of the knee joint and bones.
4. MRI: To assess soft tissues and ligaments around the knee.
5. Blood Tests: To check for underlying medical conditions.
6. Bone Density Test: To assess bone health.
7. Gait Analysis: Observing how you walk to assess knee function.
8. Arthroscopy: A minimally invasive procedure to inspect the knee joint.
9. Ultrasound: To examine soft tissue structures around the knee.
10. Nerve Conduction Studies: To rule out nerve-related issues.
11. Electromyography (EMG): Measures muscle activity in the legs.
12. Genetic Testing: For hereditary conditions.
13. Biopsy: If bone tumors are suspected.
14. Standing Knee X-rays: To assess knee alignment while standing.
15. Joint Aspiration: To rule out infections or inflammation.
16. Hormone Level Tests: If hormonal imbalance is suspected.
17. Physical Function Tests: Assessing knee function during movement.
18. Electrodiagnostic Studies: To evaluate nerve function.
19. Posture Analysis: To check for overall body alignment issues.
20. Computed Tomography Angiography (CTA): To assess blood flow in the legs.

Treatments for Genu Valgum 

1. Observation: In mild cases, especially in children, close monitoring may be sufficient.
2. Physical Therapy: Exercises to strengthen leg muscles and improve knee alignment.
3. Orthotics: Custom shoe inserts or braces to support proper foot alignment.
