After a total knee replacement Surgery it can be a difficult recovery. There are several different pain medications and supplements your doctor will recommend and it's important to know which ones will work best. It is important to know that FDA approval is not required on all supplements. This means, the supplements on the shelves at your local drug store may not be safe to take. It's important to know what roles Vitamin K, C, D, and E, all play in your recovery. Consuming the foods that contain those vitamins may either hinder or encourage your recovery.
I found this to be a great source of information on what to eat and what to look to ensure a full recovery.http://www.healthline.com/health-slideshow/total-knee-replacement-vitamins-supplements
