For O-shaped legs, place the heels and soles of both feet together, relax the legs and stand upright. If there is a distance between the knees, it means you have O-shaped legs.
Generally, the severity of O-shaped legs is judged based on two indicators: normal knee distance and active knee distance.
A is an O-shaped leg and B is an X-shaped leg.
The so-called normal knee distance refers to the distance between the knees when the ankles of the two feet are close together and the legs and knee joints are relaxed when standing upright. The distance between the medial joints.
Active knee distance refers to the distance between the inner sides of the knee joints when the ankles of the two feet are close together, the legs and knee joints are pushed inwards together when standing upright.
According to the size of normal knee distance and active knee distance, "O-shaped legs" are divided into mild, moderate and severe.
◆The normal knee distance is less than 3 cm, which is mild;
◆The normal knee distance is between 3-10 cm, which is moderate;
◆A normal knee-to-knee distance greater than 10 cm is considered severe.
