Total Knee Replacement TKR: Procedure, Types, Recovery & Cost in India
- Chronic knee pain can make everyday activities like walking, climbing stairs, or even sitting uncomfortable. For people suffering from severe arthritis or joint damage, total knee replacement (TKR) may provide long-term relief and restore mobility.
- Total knee replacement surgery has become one of the most successful orthopaedic procedures worldwide, helping millions of patients regain independence and improve quality of life.
- For international patients from Asia, Africa, the Middle East, Europe, and the Americas, India has emerged as a trusted destination for knee replacement surgery due to experienced surgeons, advanced technology, and affordable treatment options.
- Through MediHelp Global, patients can access advanced orthopaedic treatment at hospitals such as Amrita Hospital Faridabad, known for comprehensive joint replacement programs.
What is total knee replacement TKR?
Total knee replacement (TKR), also called total knee arthroplasty, is a surgical procedure that replaces damaged parts of the knee joint with artificial implants.
During the surgery, the surgeon removes worn-out cartilage and bone from the knee and replaces them with metal and medical-grade plastic components designed to restore joint movement.
The procedure is often recommended when knee pain and stiffness significantly affect daily life and non-surgical treatments are no longer effective.
Common symptoms leading to TKR include:
- severe knee pain during walking or climbing stairs
- joint stiffness and swelling
- knee deformity (bow-legged or knock-knee)
- reduced mobility
- persistent pain even while resting
Knee joint anatomy and how arthritis damages the knee
The knee joint is the largest joint in the human body and plays a key role in movement.
It consists of three main bones:
- Femur (thighbone)
- Tibia (shinbone)
- Patella (kneecap)
These bones are covered by articular cartilage, which allows smooth movement and absorbs shock.
When arthritis develops, the cartilage gradually wears away. As a result:
- bones rub against each other
- inflammation develops
- pain and stiffness increase
Over time, this damage may require knee replacement surgery.
When total knee replacement surgery is recommended
Doctors may recommend TKR when other treatments fail to relieve knee pain.
Common reasons include:
Osteoarthritis
The most common cause of knee replacement is osteoarthritis, a degenerative condition that wears down cartilage over time.
Rheumatoid arthritis
This autoimmune condition causes chronic inflammation that damages joint tissues.
Post-traumatic arthritis
Previous knee injuries, fractures, or ligament damage may lead to arthritis later in life.
Failed conservative treatments
Patients who do not improve with the following:
- medications
- physiotherapy
- injections
- lifestyle modifications
may benefit from knee replacement surgery.
Types of total knee replacement
Several approaches are used depending on the patient’s condition.
Standard total knee replacement
This is the most common procedure, where damaged cartilage from the femur, tibia, and sometimes patella is replaced with artificial implants.
Bilateral total knee replacement
In bilateral total knee replacement, both knees are replaced either:
- during the same surgical session
- in staged procedures
This option may be considered for patients with severe arthritis in both knees.
Robotic total knee replacement surgery
Modern orthopaedic technology allows surgeons to perform robotic-assisted knee replacement surgery.
Robotic systems help surgeons:
- create personalized surgical plans
- improve implant alignment
- enhance surgical precision
These technologies may improve joint stability and long-term implant performance.
How total knee replacement surgery works
Total knee replacement surgery typically takes 1 to 2 hours.
The procedure usually involves four main steps.
1. Preparing the bone
The surgeon removes damaged cartilage and bone from the femur and tibia.
2. Positioning the implants
Metal components are placed on the bone surfaces to recreate the joint structure.
3. Resurfacing the patella
In some cases, the underside of the kneecap is resurfaced with a plastic component.
4. Inserting a spacer
A plastic spacer is inserted between the metal components to allow smooth joint movement.
Total knee replacement X-ray before and after surgery
X-ray imaging plays an important role in knee replacement.
Before surgery, X-rays help doctors evaluate:
- joint space narrowing
- bone deformities
- cartilage loss
After surgery, X-rays confirm the correct placement of the artificial knee implants.
Total knee replacement physiotherapy protocol
Rehabilitation is essential for successful recovery after TKR surgery.
Typical total knee replacement physiotherapy protocol includes:
Early phase (first few days)
- gentle knee bending exercises
- ankle movements to improve circulation
- assisted walking with walker or crutches
Intermediate phase (2–6 weeks)
- strengthening exercises for thigh muscles
- improved knee bending range
- walking training
Advanced phase (6–12 weeks)
- balance training
- endurance exercises
- gradual return to daily activities
Regular physiotherapy helps restore mobility and strengthen muscles around the knee.
Recovery timeline after TKR surgery
Recovery varies for each patient, but most people follow a general timeline.
First week
- hospital stay or home recovery
- assisted walking with support
Weeks 3–6
- improved mobility
- increased independence in daily activities
2–3 months
- stronger knee function
- return to most normal activities
6 months
- near full recovery and improved joint movement
Maintaining an active lifestyle and following physiotherapy recommendations improves long-term outcomes.
Total knee replacement cost in India
One major reason international patients choose India for knee replacement surgery is cost-effective treatment combined with advanced medical care.
Average cost in India
The total knee replacement cost in India typically ranges from:
₹2,50,000 – ₹5,00,000 per knee
The price may vary depending on:
- hospital location
