What is knee joint replacement?
Knee joint replacement, also known as knee arthroplasty, is a surgical procedure in which a damaged or diseased knee joint is replaced with artificial components, called implants. It is primarily recommended for patients with advanced arthritis or significant joint injuries that impair mobility and cause chronic pain.

Why is knee joint replacement necessary?
The procedure is typically necessary for individuals who experience:

• Severe knee pain that limits daily activities like walking or climbing stairs.
• Chronic inflammation and swelling that do not improve with rest or medications.
• Joint stiffness causing difficulty in bending or straightening the knee.
• No significant relief from physical therapy, medications, or other treatments.

How is the procedure performed?
During the surgery:

1. Damaged cartilage and bone are removed from the knee joint.
2. Artificial components made of metal, ceramic, or plastic are implanted to recreate joint function.
3. The surgeon ensures proper alignment and stability of the joint before closing the incision.

What are the benefits of knee joint replacement?

• Significant pain relief
• Improved mobility and quality of life
• Enhanced ability to perform daily activities
• Long-lasting results, typically 15-20 years with proper care

Common Questions

1. How long is the recovery period?
   Recovery varies but generally takes about 6-12 weeks. Physical therapy plays a crucial role in regaining strength and mobility.

2. Are there risks involved?
   As with any surgery, there are risks such as infection, blood clots, or implant issues, but these are relatively rare when performed by experienced surgeons.

3. What lifestyle changes are necessary after surgery?
   Patients are advised to avoid high-impact activities and maintain a healthy weight to ensure the longevity of the implant.

4. Is knee joint replacement suitable for everyone?
   The procedure is most effective for individuals with severe joint damage. Younger, active patients or those with certain health conditions may be advised to explore alternative treatments.
