Prior to surgery, you should pay close attention to your nutrition. Protein, calcium and vitamin D all help in the bone healing process, and your surgeon will let you know if you should be taking any supplements beyond what you’re eating. Also, it’s important to stop taking any herbal medications 2-3 weeks prior to surgery, as they may interact with the anesthesia, along with abstaining from alcohol and caffeine at least one week before your surgery, as they may cause bleeding problems during and after surgery.

Since your knees bear most of your body’s weight, heavier patients present more complications during and after surgery. So talk with your doctor about whether your recovery and physical therapy would benefit from lowering your body weight and what the right program might be for you.

Studies show that patients who smoke experience almost 50% more surgical site infections and pulmonary complications such as pneumonia¹ as patients who don’t smoke. So it may be a good time to choose to quit in the weeks leading up to your knee replacement, but if you don’t, your doctor will most likely ask you not to smoke for at least 24 hours before your surgery.

In the weeks leading up to your surgery, let your doctor know if you become ill or experience any other medical condition, including everything from a cold or the flu, to a sprain, an allergic reaction or an open wound. Your surgeon will determine if it’s necessary to reschedule your procedure.
