Symptoms of Knock Knees

 Knock knees, medically known as genu valgum, is a condition where the knees touch or angle inward while the ankles remain apart when standing. It’s common in children between the ages of 2 and 7 and often corrects itself naturally. However, in some cases—especially in adolescents and adults—knock knees can be a sign of underlying issues or may cause discomfort and require treatment.

Understanding the symptoms of knock knees is essential for early detection and management. Here’s a breakdown of the most common signs and associated issues:   

                                                                                                                                                                                                                                                  

1. Visible Inward Angle of the Knees

The hallmark symptom of knock knees is a noticeable inward angling of the knees. When standing upright with legs together:

• The knees touch, but

• The ankles remain apart (often by more than 2.5 cm or 1 inch)

This visual cue is the most common way people identify the condition.

2. Knee Pain or Discomfort

In adolescents or adults with persistent knock knees, the misalignment may put extra pressure on the knees, causing:

• Aching or throbbing pain, especially after standing or walking for long periods

• Pain that may worsen with exercise or physical activity

• Pain often localized to the inner side of the knees

3. Foot and Ankle Issues

The altered leg alignment may affect how weight is distributed, which can lead to:

• Flat feet or fallen arches

• Foot pain, particularly in the heels or arches

• Increased risk of ankle sprains or instability

4. Unusual Walking Pattern (Gait)

People with knock knees may develop a noticeable change in their walking style. This may include:

• Waddling gait or walking with feet wider apart

• Tendency to trip or stumble more often

• Fatigue in the legs during walking or standing

5. Hip or Lower Back Discomfort

Because the condition alters overall body alignment, it may also lead to:

• Hip pain, due to compensating movements

• Lower back pain, caused by imbalanced posture or improper weight distribution

6. Joint Stiffness or Limited Range of Motion

In some cases—especially when due to underlying bone conditions—people with knock knees may notice:

• Reduced flexibility in the knees or hips

• Difficulty squatting or climbing stairs
