Structural Knee Valgus, often referred to as genu valgum or knock knees, is a common orthopedic condition where the knees angle inward and touch when the legs are straightened. This condition can lead to various health issues if left untreated. In this article, we will provide simple, plain English explanations of what Structural Knee Valgus is, its types, causes, symptoms, diagnostic tests, treatment options, and relevant medications.
Types of Structural Knee Valgus
Structural Knee Valgus can be classified into two main types:
- Genu Valgum: This is the most common type, where the knees touch while standing straight, creating a noticeable gap between the ankles. It often develops during childhood and may persist into adulthood if not treated.
- Acquired Genu Valgum: This type usually occurs later in life, often due to trauma, arthritis, or other underlying conditions. It can affect one or both knees and typically requires specific treatment approaches.
Causes of Structural Knee Valgus
There are various factors that can lead to Structural Knee Valgus. Here are 20 possible causes explained in plain language:
- Genetics: Sometimes, it runs in families, and children may inherit the condition from their parents.
- Obesity: Excess weight can put added stress on the knees and contribute to the development of knee valgus.
- Muscle Imbalances: Weakness or tightness in certain leg muscles can affect knee alignment.
- Injuries: Trauma to the knee joint or the surrounding structures can lead to structural changes.
- Arthritis: Degenerative joint diseases like osteoarthritis can cause knee alignment issues.
- Rickets: A vitamin D deficiency during childhood can weaken bones and result in knee valgus.
- Bone Abnormalities: Certain bone conditions can affect the knee’s alignment.
- Connective Tissue Disorders: Conditions like Ehlers-Danlos syndrome can influence joint stability.
- Inflammatory Conditions: Conditions like juvenile idiopathic arthritis can affect the knees.

Diagnostic Tests for Structural Knee Valgus
To determine if someone has Structural Knee Valgus, healthcare professionals may use various diagnostic tests. Here are 20 tests explained in plain language:
- Physical Examination: A doctor will visually assess knee alignment and evaluate range of motion.
- X-rays: These images can reveal the degree of knee valgus and any associated bone abnormalities.
- MRI (Magnetic Resonance Imaging): MRI scans provide detailed images of soft tissues and can help identify ligament or cartilage issues.
- CT Scan (Computed Tomography): CT scans provide cross-sectional images of the knee joint, useful for assessing bone alignment.
- Gait Analysis: Observing how a person walks can reveal abnormal movement patterns.
- Blood Tests: These may be performed to rule out conditions like arthritis or nutritional deficiencies.
- Ultrasonography: Ultrasound can assess soft tissue structures and joint fluid.
- Electromyography (EMG): EMG measures muscle activity and can identify muscle imbalances.
- Joint Aspiration: Removing a small sample of joint fluid for analysis if infection or inflammation is suspected.
- Bone Density Test: Evaluates bone health to rule out conditions like osteoporosis.
- Arthroscopy: A minimally invasive procedure involving a small camera to directly visualize the knee joint.
- Nerve Conduction Studies: Assessing nerve function to rule out neuromuscular issues.
- Knee Stress Radiography: X-rays taken while applying force to the knee joint to assess instability.
- Treadmill Testing: Observing gait patterns on a treadmill to evaluate walking mechanics.
- Podiatry Assessment: Assessing foot alignment and function, as it can affect knee alignment.
- Physical Function Tests: Evaluating strength, flexibility, and balance.
- Patient History: Discussing symptoms, medical history, and family history with a healthcare provider.
- Functional Movement Screen (FMS): Assessing movement patterns to identify weaknesses.
- Weight-Bearing CT Scan: Provides detailed 3D images of the knee while bearing weight.
- Dynamometer Testing: Measures muscle strength and imbalances in the legs.
Treatment Options for Structural Knee Valgus
The treatment of Structural Knee Valgus depends on its severity, underlying causes, and individual needs. Here are 30 treatment options explained in plain language:
