Knee Replacement: What to Expect

Posted on 08/17/2020 by Finding Doc


Knee replacement surgery aims to relieve knee pain and increase knee function by resurfacing the bones that meet at the knee joint. The surgeon removes the broken and damaged portions of bone at the end of the femur (thigh-bone) and top of the tibia (shin-bone). The surgeon then replaces them with prosthetic components. Some surgeries also come up at the back of the patella, or kneecap. If you want to go for Knee replacement surgery, you should visit the Best Orthopedic Surgeon, Dr. Ashish Dewan.

Below we are describing a typical total knee replacement surgery. The actual surgery lasts for 2 hours or more per knee.

Before the procedure of Knee Replacement Surgery

For a Knee replacement Surgery in Delhi, the doctor may explain the process to you, and you could clear all your doubts regarding knee replacement surgery with him/her. Following procedures may be performed before undergoing knee replacement surgery:

  • In addition to complete medical history, your doctor may take the patient's vital signs to ensure you are in good health before undergoing the procedure. You also may have to undergo blood tests or other diagnostic tests.
  • The surgeon will ask questions regarding any medications you are taking and whether you are allergic to any medicine.
  • Declare to your doctor about your any impending pregnancy
  • Also, the doctor may ask you to keep fast before the surgery.
  • Before the procedure, you may receive a sedative to help you relax.
  • The doctor will also introduce you to your physical therapist before your surgery to discuss rehabilitation.
  • You should arrange someone to help you around the house for a week or two after you are discharged from the hospital.

During the procedure

Knee replacement surgery in Gurgaon requires a stay in a hospital. A different procedure varies depending on your condition and your doctor's practices. The Best Orthopedic Surgeon, Dr. Ashish Dewan, will ensure that you are in the best hands.

  • The surgeon will mark an area on the knee undergoing surgery.
  • The anesthesia team will ingest anesthesia to block peripheral nerves to allow muscles to function safely and effectively during physical therapy.
  • The surgeon will create an incision down the center of the knee about 8 to 10 inches long. Then he/she may cut through deeper tissue, including the quadriceps tendon, and flips over the kneecap to access the femur and tibia.
  • The knee is bent to 90 degrees to improve the surgeon's ability to access the joint.
  • To remove the arthritically damaged areas at the bottom of the femur and the top of the tibia, the surgeon uses a bone saw. To fit its new prosthesis, each bone is reshaped.
  • A surgeon may coat the back of the kneecap, or patella, and attach an implant.
  • A polyethylene like component is fixed to facilitate the patella's gliding against the new joint. A flexible cushion, typically made of polyethylene, is fixed on top of the new tibia surfaces. This spacer functions as a shock absorber between the two new prosthetic surfaces.
  • To test the fit of the components and the new knee's range of motion, the leg is flexed and extended.
  • The surgeon straightens the knee to enable the components, cement, and bone to bond together.
  • Finally, the surgeon will repair any deep tissue that was sliced during surgery and then stitch the skin at the incision.

After the Knee Replacement Surgery

After knee replacement surgery in Noida, the patient may be taken to a recovery room for a few hours while the surgical anesthesia wears off. A physical therapist will afterward see the patient and, if deemed appropriate, be discharged home on the day of surgery. However, if the patient is not deemed for discharge on the day of surgery, they must be admitted to a hospital for a few more days before getting discharged.
