Total Knee Replacement: What Is It and When Is It Needed?

What Is Total Knee Replacement?

Total knee replacement is a type of knee surgery. Doctors remove damaged parts of the knee joint and replace them with artificial parts. These new parts are usually made of metal and plastic. Often, this surgery is called knee replacement surgery or knee arthroplasty. People with severe knee pain or stiffness may benefit from this procedure. According to the CDC, total knee replacement can help improve movement and reduce pain.

Indications for Total Knee Replacement

Many people wonder, “When do you need a knee replacement?” Usually, doctors suggest this surgery when other treatments do not help. For example, you may need total knee replacement if:

  • You have severe knee pain that limits daily activities
  • Pain continues even while resting or at night
  • Your knee is stiff or swollen most of the time
  • Other treatments, like medicine or physical therapy, do not work
  • Knee pain affects your quality of life
  • Sometimes, signs you may need knee surgery include trouble walking, climbing stairs, or getting up from a chair. If you live in a city with many orthopedic centers, you may find total knee replacement in your area more easily.

    Who Is a Candidate?

    Not everyone with knee pain needs surgery. However, you may be a good candidate if:

  • You have severe arthritis in your knee
  • Your knee pain does not improve with other treatments
  • You are healthy enough for surgery
  • You want to stay active and independent
  • Doctors will check your overall health before recommending knee replacement. They may order X-rays or other tests. Sometimes, age is not the main factor. Instead, your pain level and health matter more.

    Benefits and Expected Outcomes

    Many people feel better after total knee replacement. For instance, most patients notice less pain and better movement. Some benefits include:

  • Less knee pain during daily activities
  • Improved ability to walk and climb stairs
  • Better sleep due to less pain
  • More independence and quality of life
  • According to the American Academy of Orthopaedic Surgeons, most knee replacements last 15 to 20 years. Still, following your doctor’s advice helps you get the best results.

    Risks and Considerations

    Like any surgery, total knee replacement has some risks. However, most people do well. Possible risks include:

  • Infection at the surgery site
  • Blood clots in the legs
  • Stiffness or pain after surgery
  • Problems with the artificial joint
  • Doctors take steps to lower these risks. For example, they may give you medicine to prevent blood clots. It is important to follow all instructions before and after surgery. This helps you heal faster and avoid problems.
