Knee Replacement Surgery in Kolkata: Who Needs It, Recovery & What to Expect

Climbing stairs feels like a chore. Getting up from a chair takes two attempts. A short walk to the market ends with an aching, swollen knee.

For many people in Kolkata, this is everyday life with knee arthritis. Painkillers help for a while, then stop helping. That is usually when the question comes up: do I need a knee replacement?

This guide explains who needs knee replacement surgery, what the procedure involves, what recovery really looks like, and what affects the cost of knee replacement in Kolkata. It is written by our orthopaedic team at BK Aditya Multispeciality Hospital to help you make a calm, informed decision.

What Is Knee Replacement Surgery?

In a knee replacement, your surgeon removes the damaged surface of the knee joint and replaces it with a smooth metal and medical-grade plastic implant. The new surface lets the joint glide again, which relieves pain and restores movement.

There are two main types:

• Total Knee Replacement (TKR): the whole joint surface is replaced. This is the most common option for advanced arthritis.
• Partial Knee Replacement (UKR): only the worn-out part of the knee is replaced. It suits a smaller group of patients whose damage is limited to one side of the joint.

Who Needs a Knee Replacement?

Not every painful knee needs surgery. Most patients start with non-surgical treatment. Knee replacement is usually advised when:

• Knee pain is severe and limits walking, standing or climbing stairs
• Pain disturbs your sleep or continues even at rest
• Medicines, physiotherapy, weight management and injections no longer give relief
• The knee is visibly bending inwards (bow legs) or outwards
• X-rays show advanced damage to the joint cartilage

The most common reason is osteoarthritis, the wear-and-tear arthritis seen in people over 50. Rheumatoid arthritis and old knee injuries can also damage the joint.

Try These First: Non-Surgical Knee Arthritis Treatment

In early and moderate arthritis, many patients do well without surgery. Your orthopaedic surgeon may recommend:

• Targeted physiotherapy to strengthen the thigh muscles that support the knee
• Weight reduction, because every extra kilo adds load to the knee with each step
• Pain-relief and anti-inflammatory medicines for short periods
• Knee injections in selected patients
• Walking aids, knee supports and footwear changes
• Simple home changes, like using a Western toilet and avoiding sitting cross-legged on the floor

If these steps work, surgery can be delayed or avoided. If they stop working, a replacement is a safe and well-established next step.

Robotic Knee Replacement: What Is Different?

In robotic-assisted knee replacement, the surgeon uses a robotic system to plan and guide the bone cuts and the position of the implant with high precision. The surgeon stays in control throughout; the robot is a tool that improves accuracy.

Benefits can include:

• More precise implant alignment, planned for your knee
• Smaller cuts and less damage to surrounding soft tissue
• Less pain in the early days for many patients
• A smoother start to physiotherapy

Robotic surgery is not necessary for every patient. Your surgeon will explain whether it adds value in your case.

What Happens Before, During and After Surgery?

Before surgery

You will have a detailed consultation, a physical examination and knee X-rays. Routine blood tests, an ECG and a fitness check by a physician are done to make sure surgery is safe for you. Conditions like diabetes and blood pressure are brought under control before the operation.

On the day of surgery

The operation usually takes one to two hours. Most patients receive spinal anaesthesia, so the lower body is numb. Pain relief is planned in advance so you are comfortable when you wake up.

Recovery timeline

Every patient heals at their own pace, but a typical recovery looks like this:

• Day 1–2: you stand and take your first steps with a walker, guided by a physiotherapist
• Hospital stay: usually 3 to 5 days
• Weeks 2–6: walking improves; you move from a walker to a stick, and then walk on your own
• Around 6 weeks: most daily activities, including short walks outdoors, become comfortable
• 3 months onwards: most patients walk confidently and feel close to their new normal

Regular physiotherapy is the single most important part of recovery. At BK Aditya, rehabilitation is planned together with your surgeon, from your first steps to full recovery.

Knee Replacement Cost in Kolkata: What Affects It?

The cost of knee replacement in Kolkata varies from patient to patient. The main factors are:

• One knee or both knees (unilateral or bilateral surgery)
• Type of implant chosen for your age, activity level and bone quality
• Robotic-assisted or conventional technique
• Room category and length of hospital stay
• Your overall health, including any extra tests or care needed for diabetes, heart or kidney conditions
• Physiotherapy and follow-up visits after discharge

Most health insurance policies cover knee replacement, subject to your policy terms. Our team will give you a clear estimate after your consultation, so there are no surprises.

Life After a Knee Replacement

A knee replacement can give you back the things arthritis took away: walking without pain, climbing stairs, travelling and spending time with family. For most patients, a modern knee implant lasts many years.

To protect your new knee:

• Keep up the exercises your physiotherapist teaches you
• Maintain a healthy weight
• Choose low-impact activity like walking, swimming or cycling
• Avoid sitting cross-legged or squatting deeply
• Attend your follow-up visits

Frequently Asked Questions

What is the right age for knee replacement?

There is no fixed age. The decision depends on how much pain and disability you have and how damaged the joint is. Most patients are between 55 and 80, but younger and older patients can also benefit.

Is knee replacement surgery painful?

You will feel some pain after surgery, but it is well controlled with planned pain relief. Most patients find the pain after surgery far easier than the arthritis pain they lived with before.

How soon can I walk after knee replacement?

Most patients take their first steps with a walker within a day or two of surgery.

Can both knees be replaced at the same time?

Yes, if your health allows it. Your surgeon will discuss whether doing both knees together or one at a time is safer for you.

Does insurance cover knee replacement in Kolkata?

Most health insurance policies cover knee replacement. Coverage depends on your policy, so our team will help you check the details before admission.
