What is Knee Replacement?

Knee replacement is a surgical procedure that helps individuals with chronic knee pain and limited mobility regain function and comfort. During the procedure, the damaged parts of the knee joint are replaced with artificial components made of metal and plastic. These implants restore movement, reduce pain, and allow patients to return to an active lifestyle.

Who Might Need Knee Replacement?

Knee replacement is typically recommended when:

  • Severe Pain: Persistent pain that doesn’t improve with medication, physical therapy, or other non-surgical treatments.
  • Reduced Mobility: Difficulty walking, climbing stairs, or performing daily tasks due to joint damage.
  • Chronic Knee Conditions: Degenerative joint diseases such as osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis.

How Do You Know If You Need Knee Replacement?

Common signs that may indicate the need for knee replacement include:

  • Persistent Pain: Ongoing pain in the knee, even while resting.
  • Swelling and Inflammation: Chronic swelling that doesn’t respond to standard treatments.
  • Limited Range of Motion: Difficulty fully bending or straightening the knee.
  • Joint Stiffness: A stiff sensation that limits knee movement.
  • Instability: Feeling that the knee may give out during activity.

What Causes the Need for Knee Replacement?

Knee replacement is often required when joint damage results from the following conditions:

Osteoarthritis

The most common cause, where cartilage in the knee wears away over time, causing pain and stiffness.

Rheumatoid Arthritis

An autoimmune disorder that leads to inflammation and damage in the joint lining.

Post-Traumatic Arthritis

Arthritis that develops after a serious knee injury, such as a fracture or ligament tear.

Other Conditions

Diseases like gout, bone deformities, or bone dysplasia can also damage the knee joint and require replacement.

How is Knee Replacement Surgery Done?

Preparation

Your doctor will conduct a thorough evaluation, including a review of your medical history and imaging tests like X-rays to assess joint damage.

Anesthesia

You’ll be given either general anesthesia (to put you to sleep) or regional anesthesia (to numb the lower part of your body).

Surgery

The surgeon makes an incision over the knee and removes the damaged bone and cartilage. Artificial implants made of metal and plastic are then positioned to replicate the knee’s normal function.

Closing the Incision

The incision is closed using sutures or staples, and the area is bandaged.

Recovery

Following surgery, you’ll begin a recovery program that includes hospital monitoring and physical therapy to regain movement and strength.

What to Expect After Knee Replacement

Recovery varies from person to person but generally involves:

  • Hospital Stay: Most patients remain in the hospital for a few days post-surgery.
  • Physical Therapy: A structured therapy plan helps improve strength, range of motion, and mobility.
  • Medications: Prescriptions may include pain relievers and antibiotics.
  • Follow-Up Appointments: Routine visits with your surgeon help ensure proper healing and track progress.

Pros and Cons of Knee Replacement

Pros:

  • Pain Relief: Significantly reduces or eliminates chronic knee pain.
  • Enhanced Mobility: Improves walking, stair climbing, and other physical activities.
  • Better Quality of Life: Enables a more active, independent, and pain-free lifestyle.

Risks:

  • Infection: A potential, but rare, surgical complication.
  • Blood Clots: Preventive measures like medication or compression stockings may be used.
  • Implant Wear: Over time, implants may wear out and require revision surgery.
