Why does an injured foot turn purple upon standing?

Question

Hello doctor,

My 12-year-old son has a possible fracture in his knee. We have an appointment at the fracture clinic after a week. However, his leg and foot turn purple every time he stands up. Though not bright purple, there is a significant difference compared to the other foot. Is it normal for this type of injury?

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your son had an injury and has knee pain. Change in color when compared to the other foot is not normal. However, if your son had a fracture, he would not be able to stand up or walk. I suggest you get an X-ray of the affected area, both anteroposterior and lateral views, and share the reports. Meanwhile, I suggest he use a long leg knee brace to avoid movement and advise him not to pull weights or walk.

I hope this helps.

Thank you.
