Knee pain can be life-altering. Simple activities like walking, climbing stairs, or even standing for a few minutes can become difficult. For many people suffering from severe arthritis or joint damage, knee replacement surgery offers a new lease on life.
But one of the biggest concerns patients have is uncertainty—What will happen before surgery? Is the procedure painful? How long will recovery take?
This detailed guide will walk you through every stage of knee replacement surgery, helping you feel informed, confident, and prepared.
What is Knee Replacement Surgery?
Knee replacement surgery, also known as knee arthroplasty, is a procedure where damaged parts of the knee joint are replaced with artificial implants.
It is commonly recommended when:
- Medications no longer relieve pain
- Mobility is severely restricted
- Daily activities become difficult
- Joint damage is advanced
Common Reasons for Knee Replacement
1. Osteoarthritis
The most common cause, where cartilage wears away over time.
2. Rheumatoid Arthritis
An autoimmune condition causing joint inflammation.
3. Injury or Trauma
Fractures or ligament damage leading to long-term joint problems.
Signs You May Need Knee Replacement
- Persistent knee pain even at rest
- Swelling and stiffness
- Difficulty walking or climbing stairs
- Limited range of motion
- Poor response to medications or physiotherapy
BEFORE Surgery: Preparation Phase
