Knock Knees

Several factors contribute to the development of knock knees. These can vary based on age, underlying health, and environmental influences:

1. Developmental Changes: In children, knock knees are often a normal phase of skeletal development. As their bones grow and strengthen, the alignment of the knees and legs naturally shifts. This process usually leads to a straighter leg posture by the time they reach late childhood or early adolescence.
2. Genetic Influences: Family history of skeletal or joint abnormalities can predispose individuals to genu valgum. Genetic conditions, such as Marfan syndrome or Down syndrome, may also contribute to knock knees.
3. Obesity: Excess body weight places additional stress on the knees, potentially exacerbating or contributing to genu valgum over time.
4. Injury or Trauma: Injuries affecting the growth plates of the thigh bone or the lower leg bone called the tibia can result in abnormal bone growth and misalignment, leading to knock knees.
5. Bone Disorders: Conditions such as rickets (caused by vitamin D deficiency) or osteomalacia can weaken bones, leading to improper alignment of the knees and legs.
6. Arthritis and Joint Degeneration: Adults may develop knock knees as a result of osteoarthritis, a degenerative joint condition that alters the knee’s structure and alignment.
7. Neuromuscular Disorders: Conditions affecting the muscles and nerves, such as cerebral palsy, can impact the alignment and stability of the knees.

Knock knees often present with visible physical misalignment, but additional symptoms may vary depending on the underlying cause and severity of the condition:

• Gait abnormalities: Individuals with knock knees may walk with an awkward or unbalanced gait, potentially leading to discomfort or instability.
• Pain or discomfort: In some cases, knock knees can cause knee, hip, or ankle pain due increased pressure and pain in the front of the knee and altered weight distribution and strain on the joints. This often leads to arthritis. In children, mild knock knees are typically painless and do not interfere with mobility. Persistent or severe symptoms warrant medical evaluation.
• Difficulty with activities: Severe cases of genu valgum can make physical activities, such as running or jumping, more challenging.
• Joint stiffness or swelling: When associated with arthritis or other joint conditions, knock knees may cause inflammation and limited range of motion.
• Uneven wear on footwear: Misaligned knees can lead to uneven pressure on the feet, resulting in abnormal shoe wear patterns.

A thorough evaluation by an orthopedic specialist, such as Dr. Connor Ziegler, is essential for diagnosing knock knees and identifying any underlying causes. The diagnostic process typically involves the following steps:

1. Medical History: Dr. Ziegler will inquire about the patient’s symptoms, developmental history, and any history of trauma, illness, or family conditions that may contribute to genu valgum.
2. Physical Examination: Dr. Ziegler will perform a detailed physical examination to assess the alignment of the knees, hips, and ankles. He may observe the patient’s gait and check for signs of joint stiffness, tenderness, or swelling. A biomechanical evaluation can provide insights into how the misalignment is affecting movement patterns and joint function.
3. Imaging Studies: X-rays or other imaging modalities may be ordered to evaluate the bones and joints in detail. This helps identify structural abnormalities, such as growth plate issues, bone deformities, or joint degeneration.
4. Blood Tests: If bone disorders like rickets are suspected, blood tests may be performed to check for vitamin D deficiency or other metabolic abnormalities.
