Total Knee Replacement Surgeon in Delhi NCR
Total Knee Replacement (TKR), also known as knee arthroplasty, is a surgical procedure that replaces a damaged or worn-out knee joint with an artificial implant. This surgery has become a standard treatment for patients suffering from severe knee pain or dysfunction caused by arthritis, injury, or other degenerative joint diseases. With advancements in medical technology and surgical techniques, TKR now offers excellent outcomes, improved mobility, and enhanced quality of life.
Understanding the Knee Joint
The knee is one of the largest and most complex joints in the human body. It connects the thigh bone (femur) to the shin bone (tibia), with the kneecap (patella) sitting in front. Cartilage covers the ends of these bones, allowing smooth movement and absorbing shock. Ligaments and tendons provide stability and movement.
When the cartilage wears away due to arthritis or injury, bones rub against each other, causing pain, swelling, stiffness, and reduced mobility. In advanced cases where conservative treatments like medication, physical therapy, and lifestyle changes fail, total knee replacement is recommended.
Who Needs a Total Knee Replacement?
TKR is typically considered for individuals who experience:
- Severe knee pain or stiffness that limits daily activities such as walking, climbing stairs, or standing up.
- Moderate to severe pain during rest or at night.
- Chronic inflammation and swelling that does not improve with medication or rest.
- Knee deformity, such as bowing in or out of the knee.
- Failure of nonsurgical treatments like physical therapy, corticosteroid injections, or assistive devices.
The most common condition leading to TKR is osteoarthritis, a degenerative joint disease usually occurring in older adults. Other conditions include rheumatoid arthritis, post-traumatic arthritis, and avascular necrosis.
Types of Knee Replacement
- Total Knee Replacement (TKR):
Replaces the entire knee joint—both sides of the femur and tibia, as well as the underside of the patella. - Partial Knee Replacement (PKR):
Replaces only the damaged part of the knee. Suitable for patients with arthritis in only one compartment of the knee. - Bilateral Knee Replacement:
Both knees are replaced at the same time or staged in separate surgeries. - Revision Knee Replacement:
A second surgery performed when the initial knee replacement fails or wears out.
Preoperative Evaluation
Before undergoing TKR, patients are evaluated through:
- Medical history and physical examination
- X-rays to assess the extent of joint damage
- MRI or CT scans, if needed
- Blood tests and ECG to ensure the patient is fit for surgery
The patient is counseled about the procedure, risks, benefits, and postoperative care. Smoking cessation, weight management, and strengthening exercises may be recommended before surgery.
The Surgical Procedure
Duration: Around 1 to 2 hours
Steps:
- Anesthesia: General or spinal anesthesia is administered.
- Incision: A surgical cut is made to expose the knee joint.
- Bone Preparation: Damaged cartilage and bone from the femur, tibia, and patella are removed.
- Implant Placement: Metal and plastic components are positioned to recreate the surface of the joint.
- Stabilization: The artificial joint is tested for movement and stability.
- Closure: The incision is closed with sutures or staples and covered with a sterile dressing.
Types of Implants
Knee implants are usually made of metal alloys (cobalt-chromium, titanium) and medical-grade plastics (polyethylene). Common designs include:
- Fixed-bearing implants
- Mobile-bearing implants
- Posterior-stabilized implants
- Cruciate-retaining implants
The choice of implant depends on the patient’s age, activity level, bone quality, and surgeon’s expertise.
Recovery and Rehabilitation
Hospital Stay: 2 to 5 days, depending on the patient’s condition and hospital protocol.
Immediate Postoperative Care:
- Pain management with medications
- Prevention of blood clots using anticoagulants and compression stockings
- Early mobilization with the help of a walker or crutches
Physical Therapy: Begins within 24 hours after surgery and continues for several weeks. It focuses on:
- Improving range of motion
- Strengthening leg muscles
- Gradually increasing walking distance
- Learning to perform daily activities safely
Full Recovery Time: Usually 3 to 6 months, but it may take up to a year for complete healing.
Benefits of Total Knee Replacement
- Significant reduction in pain
- Improved mobility and function
- Better quality of life
- Long-lasting results (implants can last 15–25 years)
- High success rate (over 90% patient satisfaction)
Risks and Complications
Though TKR is generally safe, like all major surgeries, it carries certain risks:
- Infection
- Blood clots
- Implant loosening or wear
- Nerve or blood vessel injury
- Stiffness or limited motion
- Persistent pain
Choosing an experienced orthopedic surgeon and following postoperative guidelines can minimize these risks.
Cost of Total Knee Replacement in India
India is a popular destination for affordable and high-quality TKR. The cost varies depending on the hospital, city, implant type, and surgeon’s fee
International patients often choose India for the combination of advanced medical facilities, skilled surgeons, and lower costs compared to Western countries.
Life After Knee Replacement
Post-surgery, patients can return to most routine activities, including walking, swimming, cycling, and even light sports. However, high-impact activities like running or jumping should be avoided.
Regular follow-ups are essential to monitor the implant’s performance. Patients are encouraged to maintain a healthy weight, stay active, and avoid injury to prolong the life of the artificial joint.
Conclusion
Total Knee Replacement is a life-changing procedure for individuals suffering from chronic knee pain and disability. With the right surgical team, advanced techniques, and disciplined rehabilitation, patients can enjoy pain-free movement and a significantly improved quality of life. As medical science continues to evolve, knee replacement surgery is becoming more precise, less invasive, and more durable, giving hope to millions worldwide.
