Patient Education: Knee Replacement

What to Expect After Knee Replacement Surgery

After surgery, you will be taken to the Recovery Room for a period of close observation. Your blood pressure, pulse, and temperature will be monitored and close attention will be paid to the circulation and sensation in your legs and feet. Post operatively, you may have temporary nausea and vomiting due to anesthesia or medications. (Anti-nausea medication may be given to you when you are in your room to minimize nausea and vomiting.) It is also important to tell your nurse if you experience any numbness, tingling, or extreme pain in your legs or feet. When your condition is stabilized, you will be transferred to your hospital room. 

When you wake up from surgery, you will rest in bed with your bandaged leg slightly raised by a pillow. A tube (called a hemovac) that may have been placed in you during surgery will drain excess fluid to keep swelling down, while an intravenous (IV) line may be used to provide fluids for nourishment, medication to prevent blood clots, and antibiotics to prevent possible infection. You may also have a catheter placed to aid in urination. To relieve pain, you can be attached to a special device that will allow you to get pain medication when you feel it is necessary. 

At first, you will be restricted to ice chips and clear liquids, but your diet will be allowed to progress as your condition permits. Meanwhile, the surgeon and physical therapist will work together to set movement guidelines for you. The physical therapist may also recommend some gentle exercises that will help strengthen your new knee. 

After total knee replacement surgery, it takes only a few months to regain strength and confidence in your new knee. With the help of your orthopedist and physical therapist, activities that you were not able to do before surgery can be enjoyable again.
