Knee joint replacement surgery is a surgical operation that aims to replacement of the knee joint totally with an artificial one, leading to increase ability to move without feeling any pain.


The truth about knee replacement surgery (How is it done?)


Here we talk about the Steps of knee joint replacement surgery at the World Orthopedic Specialist Center.
Our medical team within the center is keen to follow international medical standards during the operation, and in our center, any operation goes through three main stages:

  • The preparative stage.
  • The operation itself.
  • The postoperative stage.

The preparative stage.


At this stage, there is an integrated healthcare team that prepares the patient for the operation from the stage of examination and assessment of his health status until he enters the operating room, and the preparations for knee replacement surgery include:

  • A comprehensive examination to assess the patient’s state of Health and the appropriateness of undergoing anesthesia.
  • Perform a set of necessary tests before surgery such as blood tests, ECO, chest X-ray, and sometimes a urine sample analysis.
  • ask the patient about:


1- Medications he is taking if any.
2- Diseases that he suffers from other than arthritis.
3- Is he allergic to certain drugs or to a certain type of anesthesia?

  • The patient should stop eating and drinking at least 8 hours before the operation.

knee surgery (during the operation)

The first step is always general anesthesia; the anesthesiologist’s task during the operation will be to monitor the heart rate, blood pressure, breathing, and the percentage of oxygen in the blood, while the orthopedist makes the steps of surgery, which include:

  • Clean the operation site with an antiseptic solution (knee area) and remove excess hair.
  • Make a surgical incision (15 to 25 cm long) in the knee area to remove the damaged joint.
  • install the new artificial joint and moves the knee right and left to make sure it is stable in the right place.
  • close the incision with sutures, and the doctor may add tubes to drain fluid and then cover the wound with medical bandages.

The postoperative stage.

There are some instructions you have to follow after total knee arthroplasty, including:

  • Take the Prescribed antibiotics and analgesics to relieve pain after the expected knee surgery.
  • Move the foot and ankle to increase blood flow to the joint and prevent the formation of clots.
  • After a short period of time, the patient must undergo physical therapy to start moving his knee, either at home or inside the physiotherapy center.
  • take care of the wound until it heals completely.


Following these instructions will help in making knee replacement surgery recovery time short.
