Knee arthritis is one of the most common reasons I see people in Dhaka and across Bangladesh struggling with walking, climbing stairs, or standing for routine household work. Many patients tell me they have tried pain medicine, home remedies, massage, and sometimes injections. Some have stopped praying on the floor, stopped going to the market, or stopped visiting relatives because the knee pain has become too limiting.
In those situations, it is natural to start searching about knee replacement surgery in Dhaka. My goal in this article is to explain, in simple but medically accurate language, what knee replacement is, who may actually benefit, what evaluation usually involves, what recovery looks like, and what practical questions matter in Bangladesh.
This is educational information, not personal medical advice. Every knee is different, and the right plan depends on a careful assessment.
What knee replacement surgery means
Knee replacement (also called knee arthroplasty) is an operation where the damaged joint surfaces are replaced with artificial components. Most patients who need it have advanced osteoarthritis, where the protective cartilage has worn down and the joint becomes painful and stiff.
I usually explain it like this: knee replacement is not a “pain injection” and it is not a “simple cleaning.” It is a reconstructive procedure meant for severe joint damage that is limiting daily life.
There are different forms of knee replacement:
- Total knee replacement: most of the joint surfaces are replaced.
- Partial knee replacement: only one damaged compartment is replaced in selected patients.
- Revision knee replacement: a repeat operation when an old implant fails or complications occur.
Who may actually need knee replacement
In my practice, I do not decide based on an X-ray alone. Some patients have severe pain with only moderate X-ray change. Others have very bad X-rays but cope reasonably well. What matters is the combination of symptoms, function, and joint damage.
Knee replacement is more likely to be considered when patients have:
- pain that limits walking, stairs, prayer posture, or standing for routine activities
- night pain or pain at rest
- stiffness that prevents bending or straightening the knee properly
- swelling that keeps returning
- deformity such as bow legs or knock knees
- failure of a structured non-surgical plan over time
If your main problem is temporary inflammation, a muscle imbalance, or a treatable meniscus issue, knee replacement may not be the correct first step. That is why evaluation matters.
What evaluation usually includes
When I evaluate patients considering knee replacement surgery in Dhaka, I focus on four practical areas: diagnosis, severity, medical fitness, and recovery readiness.
1. History and examination
I ask how the pain started, where it hurts, what movements worsen it, and how it affects daily life. I also assess:
- walking pattern
- range of motion
- ligament stability
- swelling and tenderness
- alignment and deformity
- hip and spine contribution (sometimes hip or back problems refer pain to the knee)
2. Imaging
X-rays are the main starting test for arthritis assessment. MRI is not always necessary in advanced arthritis and may not change the plan. In some cases, additional imaging is useful for planning.
3. Medical assessment
In Bangladesh, many patients have diabetes, hypertension, heart disease, kidney issues, anemia, or asthma. These conditions do not automatically block surgery, but they must be optimized. A safe anesthetic plan, infection prevention, and clot prevention require medical preparation.
4. Practical recovery planning
This part is often ignored, but it is crucial. I usually ask:
- Who will help at home during the first weeks?
- Is physiotherapy available near home, or will travel to Dhaka be needed?
- Are stairs a major issue at home?
- What is the realistic budget for implants, hospital stay, and rehabilitation?
