Knee Replacement Surgery

When do You Require a Knee Replacement Procedure?

The doctor usually assesses the level of immovability before deciding that surgery is a last resort. The deciding points are:

  1. The movement of the patient is severely or completely obstructed.
  2. The legs are bent in or out.
  3. There is severe inflammation around the knee that does not go away with pain medications and anti-inflammatory medicines.
  4. Persistent pain and inflammation in the knees even while resting.

What Happens During the Surgery?

Knee replacement surgery involves the following steps:

  1. The doctor removes the damaged knee surface.
  2. A prosthesis made up of metal or plastic or both is set over the knee area.
  3. Nowadays, the cemented prosthesis is used which is joined to the limbic bones with the help of prosthesis cement.
  4. The patient is put to intensive care for the following 3-4 weeks.

What After-care Should be Taken After the Surgery?

The knee replacement surgery in itself is not a complex procedure. However, its aftercare is. The knee is an important aspect of movement and its proper healing after the surgery needs care and precautions. Following should be done after the surgery:

  1. Complete adherence to the doctor’s advice: The surgery is followed by a long period of hospital stay. During this period, the patient needs to follow the medications, physical therapies and should not indulge themselves in anything that puts excessive stress in the body.
  2. Physiotherapy: The knee movement should begin soon after the surgery. However, this does not mean that you start your rigorous regime. The movement usually starts with a continuous passive motion machine under the guidance of a certified physiotherapist. The intensity and complexity are gradually increased.
  3. Precautions in the movement: You should always be attentive while moving to ensure that you do not fall on your knees. It is advisable to use walking aids and support. Avoid climbing stairs. Try not to walk past the slippery surface or loosely carpeted areas.
  4. Proper medications: Knee arthroplasty needs timely medicines for total recovery. Do not skip the anti-inflammatory and pain medications. If you are prescribed antibiotics, always complete the dose. Leaving it in mod-way not only increased the risk of sepsis but also makes your body antibiotic-resistant.
  5. Manage lifestyle: While this is not a must-do thing, managing lifestyle positively can definitely make your life better. Knee damage is also caused by obesity. So, if you manage your weight, it will put less pressure on the new prosthesis.

Total knee replacement surgery is now one of the most common surgeries. However, people tend to ignore the doctor’s advice which leads to more complications. A good after-care ensures a longer stay of the replaced knee.
