Knee replacement surgery is performed to replace the damaged areas of the knee joint with an artificial knee called a prosthesis. The surgery to implant both of the prosthesis is termed a Bilateral Total Knee Replacement.
During the procedure
Knee replacement surgery will last up to 2-3 hours.
- An intravenous (IV) line may be started in your arm or hand & a urinary catheter is inserted.
- The skin over the surgical site will be cleansed with an antiseptic solution.
- An incision is made in the knee area.
- Surgeon will then remove the damaged surfaces of the knee joint and resurface the knee joint with the prosthesis.
- The knee prosthesis is made up of metal and plastic. The most common type of artificial knee prosthesis is a cemented prosthesis. A cemented prosthesis attaches to the bone with surgical cement.
- Prosthesis is mostly comprised of 3 components: the tibial component (to resurface the top of the tibia or shin bone), the femoral [thigh bone] component (to resurface the end of the thighbone and the patellar component (to resurface the bottom of the kneecap that rubs against the thighbone).
- Incision will be closed with stitches or surgical staples & a drain may be placed in the incision site to remove fluid.
- A sterile bandage or dressing will be applied.
After the procedure
After the surgery, patient is kept in the recovery room for few hours. Patient will be hospitalised for 4-6 days. Mostly people recover within 12 months after the surgery, but the recovery time will differ depending on the age and overall health.
