Flat feet can lead to which of the following conditions?

Flat feet, also known as fallen arches, can significantly affect an individual's overall alignment and posture. This condition occurs when the arches of the feet collapse, causing the soles to come into complete or near-complete contact with the ground. When flat feet are present, the alignment of the lower limbs is altered, leading to changes in how force and weight are distributed during standing, walking, and running.

One of the resultant postural issues is the development of knock knees, a condition where the knees angle in and touch one another when the legs are straightened. The misalignment caused by flat feet can lead to abnormal strain on the knees, as well as supporting structures such as the hip and ankle. This added stress can cause the knees to buckle inward, contributing to the characteristic appearance of knock knees.

In contrast, the other conditions listed – anterior pelvic tilt, hyperlordosis, and hyperkyphosis – may not have the same direct connection to flat feet as knock knees do. While it's true that postural issues can lead to various compensatory adaptations throughout the body, the biomechanics of flat feet more closely correspond to the development of knock knees due to the specific alignment changes they cause in the legs and lower body. This understanding is crucial for those studying
