Joint Replacement Knee Surgery



April 13, 2024

  • Knee replacement surgery, also known as knee arthroplasty, is a medical procedure aimed at relieving pain and restoring function in severely diseased knee joints.
  • The surgery involves replacing the damaged surfaces of the knee joint with artificial components made of metal and plastic.
  • This procedure is typically recommended for individuals who have severe arthritis or have suffered significant knee injuries.
  • Here are some key aspects related to knee replacement surgery:
  • Candidates: People who usually consider knee replacement surgery have severe knee pain, stiffness, and reduced mobility that hasn’t improved with conservative treatments like medication, physical therapy, or the use of walking supports.
  • Types of Knee Replacement: There are different types of knee replacement surgeries:
  • Total knee replacement: Involves replacing the entire knee joint.
  • Partial knee replacement: Involves replacing only the damaged part of the knee joint.
  • Bilateral knee replacement: Involves replacing both knees, either simultaneously or in separate surgeries.
  • Procedure: During the surgery, the damaged portions of the knee joint are removed, and the ends of the bones are reshaped. Metal implants are then secured to the ends of the bones, and a plastic spacer is inserted between them to create a smooth, gliding surface. The procedure can take a few hours.
  • Recovery: After surgery, physical therapy is a crucial part of the recovery process. It helps regain strength and mobility in the knee. Patients are encouraged to walk with the help of assistive devices initially and gradually transition to walking without aid. Full recovery may take several months.
  • Risks: Like any surgery, knee replacement has potential risks, including infection, blood clots, implant failure, and stiffness. However, complications are relatively rare.
  • Longevity: With advancements in medical technology and improved surgical techniques, artificial knees are designed to last for around 20 years or more. Actual longevity can vary based on various factors, including the patient’s activity level and overall health.
  • It’s crucial to discuss all the pros and cons, as well as your expectations, with your orthopedic surgeon.
  • They can provide personalized information based on your specific condition and help you determine if knee replacement surgery is the right option for you.
