Frequently Asked Questions – Knee Replacement

What is involved in a knee replacement?

In total knee replacement surgery, the parts of the bones that rub together and cause pain are resurfaced and replaced. The new joints can be either plastic or metal, and are selected by your surgeon.

Should I have physical therapy before my surgery?

Sometimes your surgeon will prescribe pre-operative therapy to begin exercises that strengthen the muscles in your leg.

What should I expect for pain control after my surgery?

You will work in partnership with your nurse to use pain medications prescribed by your surgeon to help control pain.

When does my physical therapy begin after my surgery?

Therapy will begin as soon as possible after your surgery. Your nurse and the rehabilitation specialist will encourage you to walk in the hall and to exercise in bed. You will also receive instructions about home safety and tips for making your daily routines easier at home.

Will I be able to go home when I leave the hospital?

A majority of patients who have joint replacement surgery go directly home following surgery.

How long will I be in the hospital?

Most patients go home on the second or third day after surgery.

Can I have physical therapy at home?

Home services can be arranged, if you and your surgeon feel it is appropriate.

Will I need outpatient physical therapy?

Depending on your progress, your surgeon may prescribe outpatient physical therapy.

What if I need to go to a rehabilitation facility before going home?

A Care Coordinator will assist you with the referral process. A plan will be determined by you and your surgeon, based on your needs.

How soon can I return to normal activities after surgery?

Always check with your surgeon before resuming activities such as working, driving, flying, and antibiotics for dental and other procedures.

Will an implant set off a metal detector?
