Millions of people suffer from chronic knee pain caused by arthritis, injuries, or age-related wear and tear. When medications, physiotherapy, and lifestyle changes no longer provide relief, knee replacement surgery can restore mobility and improve quality of life.

At Samanvay Hospital, we provide advanced orthopedic care using modern surgical techniques, experienced orthopedic specialists, and comprehensive rehabilitation programs to help patients return to an active lifestyle.

What Is Knee Replacement Surgery?

Knee replacement surgery, also known as Total Knee Replacement (TKR), is a procedure in which damaged cartilage and bone are replaced with artificial implants designed to restore normal knee function.

The surgery helps relieve pain, improve movement, and correct deformities caused by severe arthritis or injury.

Who Needs Knee Replacement Surgery?

You may be a suitable candidate if you experience:

• Severe knee pain while walking or climbing stairs
• Persistent swelling in the knee
• Knee stiffness that limits movement
• Difficulty standing after sitting
• Pain even while resting
• Bowing or deformity of the knee
• No improvement with medicines or physiotherapy

If these symptoms interfere with your daily routine, consulting an orthopedic specialist is recommended.

Common Causes of Knee Damage

Several conditions can lead to knee replacement surgery, including:

Osteoarthritis

The most common reason for knee replacement, where the protective cartilage gradually wears away.

Rheumatoid Arthritis

An autoimmune disease that causes inflammation and damage to the joints.

Post-Traumatic Arthritis

Develops after fractures or serious ligament injuries.

Sports Injuries

Repeated injuries can accelerate cartilage damage.

Types of Knee Replacement Surgery

Total Knee Replacement (TKR)

The entire knee joint is replaced.

Partial Knee Replacement

Only the damaged portion of the knee is replaced.

Revision Knee Replacement

Performed when a previous knee implant needs replacement.

Benefits of Knee Replacement Surgery

Patients often experience:

• Significant pain relief
• Better mobility
• Improved walking ability
• Enhanced quality of life
• Better sleep
• Greater independence
• Long-lasting results

Modern implants can often last 15–20 years or longer, depending on activity level and overall health.

How Is the Procedure Performed?

The surgery generally involves:

1. Pre-operative evaluation
2. Administration of anesthesia
3. Removal of damaged cartilage and bone
4. Placement of artificial implants
5. Testing joint movement
6. Closing the incision
7. Recovery and rehabilitation

The procedure typically takes 1 to 2 hours, although the exact duration varies by patient.

Recovery After Knee Replacement

Recovery usually follows this timeline:

Day 1

Patients are encouraged to begin walking with assistance.

First Week

Physiotherapy begins to improve flexibility and strength.

4–6 Weeks

Most patients resume many daily activities.

3 Months

Noticeable improvement in mobility and reduced discomfort.

6–12 Months

Maximum recovery is typically achieved during this period.

Following your surgeon’s rehabilitation plan is essential for the best outcome.

Tips for Faster Recovery

• Follow physiotherapy exercises regularly
• Maintain a healthy weight
• Eat a balanced, protein-rich diet
• Avoid high-impact activities until cleared by your doctor
• Attend all follow-up appointments
• Keep the surgical wound clean as advised

Are There Any Risks?

Like any surgery, knee replacement carries some risks, including:

• Infection
• Blood clots
• Implant loosening over time
• Stiffness
• Bleeding
• Nerve injury (rare)

Choosing an experienced orthopedic team and following post-operative instructions can reduce these risks.
