What causes Knock Knees in Adults?

Knock knees can be described as a condition where a person's knees bend inwards and possibly touch one another when the person straightens his or her legs. This condition is caused due to a weakness of the person's abductor muscles that are present outside the thighs and hips.

Knock knees can also be a result of:

Severe lack of vitamin D, C and calcium

An injury or infection in your knee or leg

Obesity

Genetic conditions
