Is your knee pain stopping you from walking, climbing stairs, or enjoying daily life? If yes, you may need a knee replacement. Many people in Kolkata live with knee pain for years. But they do not have to. Knee replacement surgery can give you your life back.
In this blog, Dr. Siddhant Gupta explains everything you need to know about knee replacement surgery in Kolkata — in simple words.
What Is Knee Replacement Surgery?
Knee replacement surgery is also called knee arthroplasty. In this surgery, the damaged parts of your knee are removed. Then, they are replaced with artificial parts made of metal and plastic.
These artificial parts work just like your natural knee. As a result, you can walk, bend, and move without pain.
Why Do People Need Knee Replacement?
The most common reason is arthritis. Arthritis slowly damages the knee joint. Over time, the cartilage (the soft cushion inside the knee) wears away. When this happens, the bones rub against each other. This causes severe pain and stiffness.
Other reasons include:
- Osteoarthritis — the most common type in people above 50
- Rheumatoid arthritis — when the immune system attacks the joints
- Post-injury arthritis — damage caused by an old fracture or injury
- Severe knee deformity — when the knee bends inward or outward
Signs That You May Need Knee Replacement
You should see an orthopaedic doctor if:
- Your knee pain is constant and severe
- Pain medicines and physiotherapy are no longer helping
- You cannot walk more than a few minutes without pain
- Your knee is swollen most of the time
- You find it hard to climb stairs or get up from a chair
- Your knee pain disturbs your sleep
However, surgery is always the last option. First, your doctor will try all non-surgical methods. Surgery is only recommended when other treatments have failed.
Types of Knee Replacement Surgery
There are two main types:
1. Total Knee Replacement (TKR)
This is the most common type. The entire knee joint is replaced. It is done when both sides of the knee are damaged.
2. Partial Knee Replacement (PKR)
In this type, only the damaged part of the knee is replaced. Therefore, it is a smaller surgery. Recovery is also faster. It is suitable for patients where only one part of the knee is affected.
Your doctor will decide which type is best for you after examining your knee and X-rays.
What Happens During Knee Replacement Surgery?
Here is a step-by-step look at what happens:
- Anaesthesia — You are given anaesthesia so you feel no pain during surgery.
- Incision — The surgeon makes a cut over the knee to access the joint.
- Removing Damaged Bone — The damaged bone and cartilage are carefully removed.
- Placing the Implant — The new artificial joint (implant) is fixed in place.
- Closing the Wound — The cut is stitched and bandaged.
The entire surgery takes about 1.5 to 2 hours.
What to Expect After Knee Replacement Surgery
Recovery happens in stages. Here is what most patients experience:
Day 1–3 (In Hospital)
- You will be encouraged to sit up and move your leg gently.
- A physiotherapist will visit you and start basic exercises.
- Pain is managed with medicines.
Week 1–2 (At Home)
