Knee Replacement Home Instructions
1. Ice
Ice will help decrease pain and swelling. If you are not moving from point A to point B for the first 1-2 weeks after surgery place ice on your incision. A bag of ice wrapped in a bath towel works well or any other ice wrap you have may be fine. Keep the ice on and replace the ice when it melts. If the site is too cold, take a break.
2. Pain Medications
3. Blood Thinner
You will be placed on a blood thinner after surgery to decrease the risk of blood clots and pulmonary embolism associated with surgery. You will be placed on Aspirin, Lovenox, or Xarelto depending on your risk factors, and you should take that medication as instructed. Blood thinners are usually prescribed for 30 days after surgery.
4. Nausea
Pain medication can cause nausea. A prescription for nausea medicine, either Phenergan or Zofran, will be provided to be taken as needed.
5. Swelling and Bruising
Swelling and bruising are normal after surgery. Your thigh, knee, calf, ankle, and foot will swell after surgery. Normal daily activity causes swelling and this swelling should decrease with rest, ice, and elevation (the swelling may not completely go away in the first several months after surgery). If you experience swelling that does not go down with rest and continues to increase despite rest, ice, and elevation over a period of 36-48 hours, please call Dr. Higgins’s office to have the swelling evaluated. Bruising varies in severity from patient to patient and is typically noted on the thigh and then later in the calf and/or ankle. While not all patients develop bruising after joint replacement surgery, it can be severe in some patients and that is normal.
6. Constipation
7. Knee Dressing
Your knee dressing is called an Aquacel dressing and is an antimicrobial dressing impregnated with silver. This dressing can be kept on for 5-7 days. You will be given a replacement dressing and can change it about a week after surgery.
It is normal to have a small amount of drainage from your incision which will show on the white part of the dressing. If there is some spotting it is okay to leave the dressing in place. If the entire white portion of the dressing is red, then change the dressing. If the incision is draining more than a drop or two, call Dr. Higgins’s office to have your incision evaluated.
8. Home Exercises
The most important part of your rehab in the first 2 to 3 weeks is to bend your knee and straighten out your knee to regain your range of motion. I cannot emphasize this enough! The sooner you get your knee moving, the easier it will be to bend and the longer you wait the harder it will be.
I recommend you move your knee from the most you can straighten it out to the most you can bend it every 15 to 20 minutes while you are awake. If you do this, your rehab will go well. Your physical therapist will give you a home exercise routine to work on as well.
9. Showering
You may begin showering 48 hours after surgery if your incisions are dry/not draining. If your incision is bleeding or draining, do not shower and call Dr. Higgins’s office to have the incision evaluated.
10. Driving
To drive after surgery, you need to be able to control your vehicle and should not be under the influence of narcotic pain medication as they impair judgment. Some patients are ready to drive 1 to 2 weeks after surgery. Others need 2 – 3 months. When you do feel ready to drive, go to an empty parking lot and practice to ensure you are ready.
11. Fevers
Low-grade fevers (less than 101 degrees Fahrenheit) are common after surgery and generally last only a short period of time. These fevers are most often caused by mucus in your lungs. Deep breaths, coughing, and moving around a bit are helpful for resolving these low-grade fevers.
