What to Expect

Prior to Procedure

Your doctor may do the following before your procedure:
  • Physical exam
  • Blood tests
  • Imaging tests, like x-rays or scans
  • Electrocardiogram for heart function
  • Have you donate blood in case you need a transfusion
  • Prescribe antibiotics to prevent infection
Before surgery, you will need to:
  • Arrange for a ride home.
  • Arrange for help at home while you recover.
  • Talk to your doctor about any medications, herbs, or supplements you are taking.
  • Talk to your doctor about any allergies you have.
  • Ask your doctor about devices you will need after the surgery like a wheelchair, walker, or cane.
You may need to stop taking some medications up to one week before the procedure. Medications that may need to be stopped may include:
  • Anti-inflammatory drugs
  • Blood thinners
  • Antiplatelets
Do not eat or drink anything after midnight the day before your surgery, unless told otherwise by your doctor.

Anesthesia

General anesthesia will be used. You will be asleep during the surgery.

Description of the Procedure

An incision will be made over the knee. A small amount of bone from the ends of the thigh bone and top of the lower leg bone will be removed. Other knee joint structures like cartilage and ligaments or knee replacements will be removed. The ends of the bones will be joined together, usually with a bone graft. Metal plates will be screwed into the joined bones.
The incision will be closed. A bandage may be placed over the incision.

How Long Will It Take?

About two hours

Will It Hurt?

Anesthesia will block pain during the procedure. You will have pain after the procedure. Ask your doctor about medication to help manage pain.

Average Hospital Stay

The usual length of stay is about 3-4 days. It is possible that you may have to stay longer if complications arise. You may also go to a rehabilitation hospital to help you recover.

Post-procedure Care

At the Hospital
Right after the procedure, you may be given medication such as:
  • Pain medication
  • Antibiotics to prevent infection
  • Medication that prevents blood clots
Physical therapy often starts within 24 hours after your surgery. During this time you may need devices to help you walk.
You will be able to leave when you are able to get around and do basic daily care activities on your own.
At Home
When you return home, take these steps:
  • Follow your doctor’s instructions on cleaning the incision site.
  • Ask your doctor about when it is safe to shower, bathe, or soak in water.
  • Follow your doctor’s instructions on sitting, bending, or sleeping positions.
  • Continue with your physical therapist’s exercise program.
