• Doing the medical tests that your doctors recommend
• Talking to doctor about your currently used medicines and supplements
• Controlling any underlying diseases like diabetes and anemia

• Making clear what your surgeon and physical therapist are going to do

In fact, you may need to follow different steps to your preparation depending on the type of surgery, your age, the condition you are in medically, the medicines you use, etc., and the standard practices that your hospital follows.

Pre-Surgery Tests for Knee Replacement

In other words, your medical team can use the tests done to decide if surgery is safe for you and to discover the diseases that could require treatment before you undergo a knee replacement

The following list of preoperative investigations is provided:

1 Blood Test :

• to assess hemoglobin and the number of red blood cells in general
• to detect level of blood sugar
• to determine the functioning of kidneys and liver
• to find electrolytes
• blood clotting factors when needed
• detection of infection or signs of some diseases

If tests indicate such conditions as anemia, very high sugar level, or any other condition, your healthcare team will suggest to solve it before surgery.

2 Urinalysis

Urinalysis may be a method chosen for the identification of urinary disturbances/infection, if it is the case clinically. The decision of whether a treatment or additional evaluation is required before the surgery belongs to the physician.

3 ECG：

Doctors may suggest an electrocardiogram (ECG) to patients who are elderly and have or are at risk of heart disease. An ECG is a means for a physician to understand the heart rhythm of an individual. It may also aid in the administration of anesthetic.

4 Chest Evaluation：

Mandatory pre-operative investigations may include a chest X-ray and/or other respiratory checks, particularly for someone who is a chronic smoker or who is known to have or to have the possibility of having chronic cough or other respiratory disorders.

5 Standing Radiography and Imaging of the Knee：

A knee surgeon may ask to see standing radiographic images of the knee or other knee imaging to evaluate the extent and kind of the joint damage, the alignment of the legs, the quality of the bones, and to plan the surgery.

6 Physician and Anesthesia Interview：

After surgery or the day before the operation, it may well be that the anesthesiologist or a physician consults you. They will check your past medical history, allergies, previous anesthesia, medications you were taking, etc., and will decide upon the best way of administering anesthesia taking all this into consideration.

Blood Tests Needed Before Knee Replacement?

Blood tests for your preoperative laboratory investigation might generally involve a complete blood count (CBC), assessment of blood glucose level, kidney and liver function, electrolyte levels, and if required, clotting factor testing.

But it should be noted that no single test list fits all cases. Your attending physician and hospital will decide which preoperative investigations are deemed essential for your operation.

What To Eat Before KneeReplacement Surgery

• Chicken, Fish & eggs
• Paneer/Cheese/Tofu
• Kidney/Fresh green
• Red meats
• Nuts & seeds
• Milk & dairy

Get different types of colored fruits like mangoes, guavas, and tomatoes besides oranges and other leafy greens to add in the body various micronutrients and vitamins besides dietary fiber.

Grains

These are the main sources of dietary fiber for the human body, so, eating such kind of foods is a must at all times. So, if you are in the habit of having a meal only based on a certain staple that is highly-processed then make sure to take small portions and complement the meals through other means like having fresh salads or greenery.

Stay Hydrated

Generally speaking, drinking enough water is quite helpful, unless you are following your healthcare provider’s instructions to keep you from drinking too much water especially if you have certain diseases.

What Not To Eat or Drink?

There isn’t one specific list of all foods that every patient getting a new knee will have to avoid. Nevertheless, it is quite reasonable to limit the amounts of:

• Beady or highly-processed foods, especially ones packed in bags and bottles
• Very salty foods, e.g., those with salt added
• Excessive frying
• Overconsumption of alcohol

Before starting any herbal products, high-doses of vitamins or any other types of nutritional supplements consult your physician as some of these things could make you bleed or mix-up medication effects.

Never think about discontinuing your medicines on your own.

Doctors, anesthesiac, or other members of the surgical team should provide directions regarding which medicines can be continued, which ones may need dose modifications and which ones will be taken only temporarily. The medicines that have a direct effect on bleeding and clotting factors, blood pressure, diabetes and immunity are particularly highlighted in this respect.

Let your doctors know all the drugs and supplements that you currently take (prescription, over-the- counter and others) together with a detailed description of dosage, mode of administration and frequency to be on a safe side.
