What is a valgus deformity characterized by?

1. Knees bent outward - bowlegged

2. Knees straight - normal alignment

3. Knees bent inward - knee knocked

4. Knees locked in extension

The correct answer is: Knees bent inward - knee knocked

A valgus deformity is characterized by the knees bending inward, resulting in a "knocked knee" appearance. This condition occurs when the angle between the femur and tibia is decreased, leading the lower limbs to angled towards each other at the knees while the feet remain apart. This alignment can lead to various complications, including joint stress, discomfort, and potential issues with mobility. Recognizing the signs of valgus deformity is essential for correct diagnosis and treatment, as it directly influences how weight is distributed and can affect overall biomechanics. In contrast, outward-bent knees describe a varus deformity, while straight knees reflect normal alignment. Locked knees are indicative of other potential mechanical or orthopedic issues and do not pertain to a valgus condition. Understanding these distinctions is crucial for developing appropriate management strategies in radiography and patient care.
