What arrangements for home should I make?

Having a close friend or family member by your side to assist you through your recovery can make a huge difference in preventing a range of potential complications, from wound care to falls.

Your other option, if covered by your health insurance plan, would be to arrange for home health care services. What is covered and the duration will depend on your health insurance plan. Please check with your health insurance provider prior to making any arrangements.
 

How can I help my wound heal?

As your incision heals, it’s perfectly normal to feel some discomfort and numbness in the area. This means new nerves and tissue are growing as your body accepts your knee implant.

It’s also normal to have temporary swelling, pressure and/or bruising in your ankles and feet, and these may last for a few months. However, always discuss your symptoms with your doctor to make sure nothing disrupts your recovery.

Here are a couple things you can do to help, if directed by your doctor:

  • Ice your knee (always cover ice packs in a towel to avoid frostbite)
  • Wear compression stockings
  • Elevate your leg with a pillow
  • Ankle exercises
     

How will my pain be managed?

In the first 24-48 hours after surgery, you will likely experience substantial discomfort, varying from mild pain to pressure to significant pain, which will be managed by your doctor with medications such as:

  • Nonsteroidal anti-inflammatory medications (NSAIDS): These are typically used to relieve arthritis, reduce inflammation and treat other causes of pain.
  • Opioids: These are typically prescribed for moderate to severe pain.

They’ll be taken prior to getting out of bed, walking or doing exercises. All of them have side effects, but not everyone gets them. The most common side effects are constipation, nausea and vomiting, sleepiness, dizziness, rash, itching and slowed breathing, and you should let your doctor know if you start to experience any of these.

To help with the pain during your rehabilitative exercises, it’s important to follow the instructions of your doctor or physical therapist, who may recommend heat before exercise and ice following.

Besides your knee, you may also experience pain in other parts of your body, such as in your throat if a breathing tube was used, or in your back, chest and/or shoulder muscles because you were lying down during and after surgery. However, these symptoms should ease with time.

After 10-14 days, you will usually be able to stop taking strong pain medications as you’re getting back to normal.
 

How do I avoid blood clots?

Once you’re at home recovering, one of the risks is blood clots. Because you aren’t moving around as much, blood collects in the veins of your legs and feet, which can lead to the formation of clots. These can move from your legs to your lungs and cause pulmonary embolism, so it’s important to do everything you can to prevent them.

After surgery, your doctor may prescribe you blood thinners that act as an anticoagulant, helping to prevent blood clots from forming.
 
Here are some additional ways that may help prevent blood clots:

  • Wear compression stockings: These are very tight-fitting knee-high socks that help your blood flow better, and your doctor may ask you to wear these for several weeks.
  • Use an intermittent compression pump device: This is similar to a blood pressure cuff that repeatedly inflates and deflates to help blood flow better in your legs.
  • Avoid wearing tight clothing for the first few weeks.
  • Keep your legs elevated: A few times a day, for the first few weeks, elevate your legs six inches above your heart.
  • Change your position often.
  • Avoid standing or sitting for more than an hour at a time.
  • Reduce the amount of salt in your diet, as it causes fluid retention.
  • Avoid bumping or injuring your legs.
  • Avoid crossing your legs when sitting.

You should also keep an eye out and contact your doctor if you see any symptoms of blood clots, such as redness, swelling or discoloration of the skin at the site of the clot, tenderness or pain at the site of the clot, or a warm feeling at the site of the clot (but not everyone experiences these).

What are the do’s and don’ts of recovery?

While it’s essential to follow your surgeon’s and physical therapist’s instructions while you recover, there are a few do’s and don’ts to make your journey to recovery as fast as possible.

Do’s

  1. Keep up with your exercises: Be sure to follow the rules of your physical therapist.
  2. Engage in lower-stress activities, such as golfing, hiking, walking, biking, stationary skiing and swimming. Ask your doctor before doing any rowing, table tennis, cross-country skiing or bowling.
  3. Take care of your lungs: Since your body needs plenty of oxygen to heal properly, make sure to do breathing exercises.
  4. Manage your pain: Be sure to take medications as prescribed by your doctor, and let them know if they aren’t doing enough to relieve the pain.
  5. Control swelling: Along with icing your knee, you should elevate it above your heart with pillows while in bed. This will help to control swelling which reduces pain and improves your circulation and range of motion.
  6. Rest: Get plenty of rest to help your knee heal. If you are having problems sleeping, speak with your doctor to see what they recommend.

Don’ts

  1. Avoid activities such as competitive racquet sports, high-impact aerobics, high-intensity jogging/running, mogul skiing, martial arts, rope jumping and rough contact sports.
  2. Don’t twist your knee: You want to avoid any jarring forces on your knee, so instead, turn your entire body to avoid stress on your knee.
  3. Avoid scheduling dental work or surgical procedures on your bladder or colon: These can cause bacteria to enter your bloodstream and may lead to infection in your new joint. Discuss any of these with your surgeon before having them done.
  4. Don’t lift heavy objects: This can cause damage to your new knee.
  5. Don’t push yourself too hard: While you want to get back to your life, it’s important you give your body the time to recover.
