Knee replacement surgery in Delhi is a highly effective procedure designed to alleviate pain and restore mobility. It involves the removal of damaged cartilage and bone from the knee joint, which are replaced with a metal and plastic implant. Whether it's a total knee replacement surgery or a partial one, the primary goal is to improve the patient’s quality of life. This surgery is commonly recommended for individuals suffering from severe osteoarthritis or other debilitating knee conditions.

1. Total Knee Replacement (TKR):
   • Total knee replacement surgery involves replacing all three components of the knee: the femur (thigh bone), tibia (shin bone), and patella (kneecap).
   • It is the most common type of knee replacement surgery and is suitable for patients with extensive arthritis or severe knee damage.
2. Partial Knee Replacement (PKR):
   • Also known as unicompartmental knee replacement surgery, it replaces only the damaged portion of the knee.
   • This procedure is ideal for patients with damage localized to one compartment, preserving the healthy cartilage and bone.
3. Revision Knee Replacement:
   • Revision knee replacement surgery is performed to replace a previously implanted joint that has worn out or failed.
   • This procedure is more complex than the initial surgery and often involves more extensive planning and surgical expertise.

Knee replacement surgery is recommended for individuals who:

• Suffer from severe knee pain or stiffness that restricts daily activities such as walking or climbing stairs.
• Experience moderate to severe knee pain even at rest, both during the day and night.
• Have chronic knee inflammation that does not respond to medications or other treatments.
• Find no relief with physical therapy, cortisone injections, or anti-inflammatory drugs.

1. Preparation:
   • Preoperative evaluations include imaging tests like X-rays or MRIs, medical history reviews, and physical examinations.
   • Patients may be advised to lose weight, stop smoking, and undertake preoperative physical therapy to strengthen surrounding muscles.
2. Surgery:
   • The procedure typically lasts 1-2 hours. The damaged joint surfaces are replaced with a knee implant, ensuring proper alignment and mobility.
   • Depending on the patient’s needs, a total knee replacement surgery or partial replacement is performed.
3. Postoperative Care:
   • Patients usually stay in the hospital for a few days for pain management and initial rehabilitation.
   • Physical therapy begins soon after surgery to restore knee movement and strength.

• Initial Recovery:
  • Patients manage pain and swelling while gradually regaining mobility with assistive devices like walkers or crutches.
  • Most can return to normal activities within 3-6 weeks.
• Rehabilitation is key to a successful knee replacement:

1. First 6 Weeks: Focus on reducing swelling and regaining knee mobility.

2. 6-12 Weeks: Strengthening exercises and increased physical activity.

3. 3-6 Months: Resume light activities like swimming and cycling while avoiding high-impact exercises.

4. Long-Term Care: Continue with regular exercises and follow-up visits to monitor the knee implant.

• Significant pain relief.
• Improved mobility and knee function.
• Enhanced overall quality of life.
• Long-lasting results with implants typically lasting 15-20 years or more.

Q1. How long does a knee replacement last?

A modern knee replacement surgery can last 15-20 years or longer, depending on factors like activity level and overall health.

Q2. Can I kneel or squat after knee replacement?

While these activities are often possible, they may feel uncomfortable. Consult your surgeon about specific limitations.

Q3. When can I return to work after surgery?

It depends on the type of work and your recovery. Office workers may return in 4-6 weeks, while manual laborers may need 3 months or longer.

Q4. What activities should I avoid after knee replacement?

High-impact sports like running, basketball, or heavy lifting are generally discouraged to prolong the life of the prosthesis. Also, sitting cross legged should also be avoided in some cases.

Q5. What is a knee implant?

A knee implant is an artificial joint that replaces the damaged or diseased parts of the knee during knee replacement surgery. It is typically made of metal alloys, ceramics, and durable plastic components.

Q6. How should I care for my knee implant post-surgery?

Caring for a knee implant involves:

• Regular Exercise: To maintain strength and flexibility.

• Weight Management: Avoiding excessive weight gain to reduce stress on the implant.

• Routine Check-ups: Regular visits to the surgeon to monitor the implant’s condition.

Q7. How do I choose the right knee implant for me?

The choice of implant depends on several factors, including:

• Age and Activity Level: Younger, more active patients may benefit from more durable or advanced designs.

• Bone Quality: Bone density can influence the type of fixation method used (cemented vs. cementless).

• Anatomy: Specific implants are designed to accommodate anatomical differences.

Your surgeon will evaluate these factors and recommend the most suitable implant.

Q8. Can a knee implant be replaced if it wears out?

Yes, if a knee implant wears out or fails, a revision knee replacement can be performed. This is a more complex surgery where the old implant is removed and replaced with a new one.
