Total Knee Replacement: What to Expect, Benefits, Risks, and Recovery

Introduction

Total knee replacement is a surgery that helps people with severe knee pain. Doctors replace the damaged knee joint with an artificial one. This surgery can improve movement and reduce pain. Many people choose total knee replacement when other treatments do not work. In the United States, this is a common way to treat knee pain and improve quality of life.

Symptoms and Conditions Leading to Total Knee Replacement

Many people suffer from knee pain that does not go away. Often, this pain comes from arthritis or injury. You may need total knee replacement if you have:

  • Severe knee pain, even when resting
  • Stiffness that makes it hard to bend or straighten your knee
  • Swelling that does not get better
  • Trouble walking, climbing stairs, or doing daily tasks
  • Knee pain that does not improve with medicine or therapy

    • Causes and Risk Factors

    There are several reasons why someone may need total knee replacement. Most often, it is due to:

  • Osteoarthritis, which wears down the knee joint over time
  • Rheumatoid arthritis, which causes swelling and pain
  • Old injuries that damage the knee

    • Some risk factors include:

  • Being over 50 years old
  • Having a family history of joint problems
  • Being overweight, which puts extra stress on the knees
  • Doing heavy work or sports that strain the knees

    • Diagnosis and When Surgery Is Recommended

    Doctors use several steps to decide if you need total knee replacement. First, they ask about your symptoms and check your knee. Next, they may order X-rays or MRI scans. These tests show how much damage is in the joint. If pain and stiffness make daily life hard, and other treatments fail, surgery may be the best choice. Your orthopedic surgeon near you will help you decide.

    The Total Knee Replacement Procedure

    Doctors follow a step-by-step process for total knee replacement surgery:

  • First, you receive anesthesia to keep you comfortable.
  • Next, the surgeon makes a small cut over your knee.
  • Then, they remove the damaged bone and cartilage.
  • After that, the surgeon places the artificial joint parts.
  • Finally, they close the cut and cover it with a bandage.

    • The surgery usually takes one to two hours. Most people stay in the hospital for a few days.

    Benefits and Expected Outcomes

    Total knee replacement offers many benefits. For example, most people notice:

  • Less knee pain
  • Better movement and flexibility
  • Improved ability to walk and do daily tasks
  • Higher quality of life

    • In addition, many people return to normal activities within a few months. According to the CDC, over 90% of knee replacements work well for at least 15 years.

    Risks and Possible Complications

    Like any surgery, total knee replacement has some risks. However, most people do not have serious problems. Possible risks include:

  • Infection at the surgery site
  • Blood clots in the leg
  • Stiffness or pain after surgery
  • Problems with the artificial joint, such as loosening
  • Allergic reaction to the materials used

    • Your doctor will explain how to lower these risks before surgery.
