Knee replacement, also known as knee arthroplasty. It is a surgical procedure to replace the weight-bearing surface of the knee joint to relieve pain and disability.

After Knee Replacement Surgery:

What To Eat And What To Avoid?

After surgery, your first priority is to heal. You want to feel better and get back to your usual activities as early as’s smart to pay attention to your diet after surgery. Proper nutrition can aid healing and recovery and eating the wrong foods at the wrong time can trigger unwelcomed complications.

Knee Replacement diet

Eat: Clear Fluids

Doctors want to be sure that your digestive system is functioning well before you start eating a solid diet. So your immediate post-surgery diet should be restricted to clear fluids:
Knee Replacement Liquid Diet

* Water
* Ice
* Coconut water
* Apple juice
* Cranberry juice
* Grape
* Tea broth
* Gelatin
* Electrolyte drinks and popsicles.
* Don’t guzzle liquid, go slowly at first.
* Adequate fluid intake will also prevent dehydration.

Avoid: Cheese

Constipation is incredibly common after surgery.

Avoid High – fat food like cheese can also trigger nausea.

 Eat: Yogurt

Most people receive antibiotics during and after surgery.

These medications can help prevent and treat infection,

but they can also disturb the balance of bacteria in the gut.

  • Yogurt contains healthy bacteria; it is unlikely to cause nausea after surgery.
  • It contains zinc and protein, two nutrients that promote healing.
  • Probiotics are the happy, healthy bacteria that your body needs to digest food, provide mental balance and fight off all the germs and infections you are prone to after a hospital stay or procedure.

some of the common forms of probiotics-rich food are:

  • Yogurt
  • Kefir
  • Sauekraut
  • Kimchi

anesthetics, antibiotics, and painkillers upset the delicate balance in your gut leaving you with digestive system upsets, constipation, and nausea.

Avoid: Fried Or Fatty Food

Fried food is not a great nutritional choice. It is a good idea to focus on foods that contain the nutrients you need to heal such as :

  • Protein
  • Vitamin C
  • Vitamin D
  • Vitamin E and zinc

Additionally, fried and fatty food can cause nausea or vomiting.

  Eat: Lean Meats And Seafood

It is an excellent post-surgical choice to promote healing.

  • Fatty fish such as
  • white caught salmon and tuna, contain omega -3 fatty acids, which can decrease inflammation in the body and prevent infection.

 Avoid: Alcohol

  • Alcohol plus pain pills can affect thinking and slow breathing to potentially dangerous levels.
  • Alcohol is also dehydrating, and your body needs plenty of healthy fluids to heal.

Eat: Berries

The antioxidants in berries help support the functioning of the immune system, which may help you avoid infection after surgery.


raspberries and blackberries are all high in vitamin c.

A handful of berries and few nuts pack a nutritional punch.

Avoid Highly Processed Food

Nutrition is the key post-surgery.

Eat: Whole Grain

Whole grain contains a lot of fiber, which may help avoid post-surgical constipation.

Whole grain includes

  • Barley
  • bulgur
  • quinoa
  • and millet also contains protein, zinc, magnesium, and B vitamins.

Eat: Dark Leafy Green

These foods are high in fiber and antioxidants, so they aid Digestion and support the immune system.

Avoid Vitamin K After Surgery

Immediately after the surgery and while taking blood thinners, it’s best to be mindful of your intake of foods that are high in vitamin K, such as:

  • broccoli
  • cauliflower
  • Brussels sprouts
  • liver
  • green beans
  • garbanzo beans
  • lentils
  • soybeans
  • kale
  • cabbage
  • onions
vitamin K enhances blood clotting.

Eat These Foods To Speed Up Recovery After Surgery

Recovery speed and effectiveness after orthopedic surgery are largely determined by what we eat. Not only does our body need more calories to recover, but surgery also causes a stress reaction in the body that elevates the metabolism and increases our need for calories.

If we don’t fuel our recovery with the proper foods, complications are more likely to arise.

We understand that you are concerned about the situation your mother is in and we are here to help. It is important that your mother continues the 5 day antibiotic course as instructed. Additionally, diet can be an important tool for managing infection and recovery. Eating foods that are rich in antioxidants such as berries, nuts, and vegetables can help boost the body’s natural healing system. Regular exercise can also be beneficial, but check with her doctor to make sure they do not have any restrictions on type or intensity of activity they suggest. Finally, make sure to keep in touch with her doctor so they can monitor her progress and ensure she gets back to good health soon!
