Total Knee Replacement
Joint Health
Welcome to our health education library. The information shared below is provided to you as an educational and informational source only and is not intended to replace a medical examination or consultation, or medical advice given to you by a physician or medical professional.
During total knee replacement surgery, your damaged knee joint is replaced with an artificial joint (called a prosthesis). This surgery almost always reduces joint pain and improves your quality of life.
Before Your Surgery
- You should stop eating or drinking 10 hours before surgery.
- If you take a daily medication, ask if you should still take it the morning of surgery.
- At the hospital, your temperature, pulse, breathing, and blood pressure will be checked.
- An IV (intravenous) line may be started to provide fluids and medications needed during surgery.
The Surgical Procedure
When to Call Your Doctor
- An increase in knee pain
- Pain or swelling in a calf or leg
- Unusual redness, heat, or drainage at the incision site
- Fever of 101.0°F or higher
- Trouble breathing or chest pain (call 911)
After Your Surgery
After surgery, you’ll be sent to the PACU (postanesthesia care unit). When you are fully awake, you’ll be moved to your room. The nurses will give you medications to ease your pain. You may have a catheter(small tube) in your bladder. A CPM (continuous passive motion) machine may be used on your knee to keep it from getting stiff. An SCM (sequential compression machine) may be used to prevent blood clots by gently squeezing then releasing your leg. Soon, healthcare providers will help you get up and moving.
