What is Knee Replacement Surgery?
Knee replacement surgery (also called knee arthroplasty) is a surgical procedure performed to relieve pain, restore function, and improve quality of life for people suffering from severe knee joint problems. It involves replacing the damaged or worn-out parts of the knee joint with artificial components called implants or prostheses.
This surgery is one of the most common and successful orthopedic procedures, especially for individuals dealing with advanced arthritis, injuries, or long-term joint degeneration.
When is Knee Replacement Needed?
Knee replacement may be recommended when:
- You have severe or constant knee pain, even while resting
- Pain prevents you from performing routine activities like walking, climbing stairs, or bending
- You experience joint stiffness, deformity (bow-legged or knock-kneed appearance)
- Non-surgical treatments like medications, physiotherapy, or injections no longer work
- Your mobility is significantly affected and quality of life is reduced
Conditions That Lead to Knee Replacement
Dr. Chandresh Sharma treats a wide range of conditions that may eventually require knee replacement surgery:
- Osteoarthritis age-related wear and tear of the knee cartilage
- Rheumatoid Arthritis autoimmune disease causing joint inflammation
- Post-Traumatic Arthritis arthritis following injury or fractures
- Avascular Necrosis death of bone tissue due to poor blood supply
- Joint deformities or congenital conditions
Types of Knee Replacement Surgery
Total Knee Replacement (TKR)
In a TKR, both the thigh bone (femur) and shin bone (tibia) surfaces are replaced with metal implants, and a medical-grade plastic spacer is inserted between them to allow smooth motion.
Suitable for patients with severe arthritis affecting the entire knee joint. Provides long-term pain relief and improved joint function.
Partial (Unicompartmental) Knee Replacement
Only the damaged part of the knee is replaced, leaving the healthy portions intact. This is a less invasive option with quicker recovery and more natural movement.
Best for patients with localized arthritis (only one side of the knee).
Dr. Sharmas Approach to Knee Replacement
Dr. Chandresh Sharma uses time-tested, non-robotic surgical techniques, with a strong emphasis on:
- Precision and alignment using traditional jigs and instruments
- Minimally invasive approaches for faster healing
- Use of internationally certified implants for durability and longevity
- Detailed pre-operative planning and post-operative rehabilitation
Step-by-Step Surgical Process
1. Pre-Surgical Evaluation
- Detailed medical history and physical exam
- Imaging tests: X-rays, sometimes MRI or CT scans
- Blood tests and anesthesia clearance
- Counseling about the procedure, risks, recovery, and outcomes
2. Surgical Procedure
- Performed under spinal or general anesthesia
- A 610 inch incision is made over the knee
- Damaged cartilage and bone are removed
- Artificial implants are fixed to the femur and tibia
- The patella (kneecap) may be resurfaced if necessary
- A spacer is inserted to enable smooth joint movement
- The surgery usually takes 1.5 to 2 hours and is followed by a monitored recovery in the hospital.
Recovery and Rehabilitation
Hospital Stay
- Most patients stay for 35 days
- Walking with support begins within 2448 hours
Physiotherapy
- Strengthens muscles around the knee
- Improves joint movement and flexibility
- Prevents stiffness and enhances balance
At-Home Care
- Pain medication and wound care instructions
- Gradual increase in walking and daily activities
- Follow-up visits to monitor progress
Full Recovery Timeline
- Most patients return to normal activities in 68 weeks
- Driving, desk work: 36 weeks
- Complete healing and implant integration: 36 months
Risks and Complications
While knee replacement is generally safe and effective, some risks include:
- Infection
- Blood clots
- Implant loosening or wear over time
- Nerve or blood vessel injury
- Stiffness or reduced range of motion
Dr. Sharma minimizes these risks by following strict surgical protocols, advanced infection control, and careful post-operative monitoring.
Long-Term Outcomes and Life After Knee Replacement
Most modern knee implants last 1520 years or more, especially when patients:
- Maintain a healthy weight
- Follow prescribed exercises
- Avoid high-impact activities like running or jumping
Activities such as walking, swimming, cycling, yoga, and light hiking are encouraged after full recovery.

Testimonials: What Patients Say
Frequently Asked Questions (FAQs)
Pain is well-controlled during and after surgery with medications. Most patients report immediate relief from arthritic pain and minimal discomfort during recovery.
Typically, 15–20 years or longer with proper care.
Sedentary jobs: 3–4 weeks; physical jobs: 8–12 weeks.
No. Walking aids are temporary, and most patients regain independent mobility.
