How Knee Replacement Surgery Works

Answers from an Orthopaedic Surgeon

Recurrent knee pain? Trouble walking or climbing stairs?

If these issues sound familiar, you’re not alone. Thousands of people in the UAE—and millions around the world—suffer from chronic knee problems caused by arthritis, injuries, or simple wear and tear over time.

I’m Dr. Bharath Patil, Specialist Orthopaedic Surgeon at RAK Hospital. Every year, I treat hundreds of patients experiencing pain, stiffness, and reduced mobility—most often due to osteoarthritis, a condition where the cushioning cartilage in the knee joint wears away. In advanced cases, bones can rub against each other, causing severe pain and difficulty with everyday activities.

Many of my patients have one question:

“Is knee replacement surgery the right solution for me?”

What Is Knee Replacement Surgery?

Knee replacement, or knee arthroplasty, is a procedure where damaged parts of the knee joint are replaced with artificial components—usually made of metal and plastic. These new parts replicate the movement of a healthy knee, relieve pain, and restore function.

There are two main types:

• Total Knee Replacement (TKR): Both sides of the knee joint are replaced.
• Partial Knee Replacement: Only the damaged part is replaced, preserving more natural tissue.

⸻When Is Surgery Needed?

You may be a candidate if:

• Your knee pain limits daily activities like walking, climbing stairs, or getting out of a chair.
• You’ve tried medications, physiotherapy, or injections without lasting relief.
• Your knee is visibly deformed or chronically swollen.
• Pain keeps you awake at night.

The goal of surgery is not just to fix the knee—but to restore your quality of life.

What Happens During Surgery?

The procedure is done under anesthesia and takes about 1 to 2 hours.

Here’s a simplified overview:

1. The damaged cartilage and bone are removed.
2. The joint is reshaped to fit the artificial components.
3. The prosthetic implants are secured into place.
4. The knee is tested for stability and smooth movement before closing.

Thanks to advances in minimally invasive techniques, many patients experience less pain and faster recovery than ever before.

What About Recovery?

Most patients begin walking (with support) within a day or two. With dedicated physiotherapy, full recovery typically takes 6 to 12 weeks, though improvement continues for up to a year.

Patients can often:

• Walk comfortably
• Climb stairs
• Return to low-impact activities like swimming, cycling, or golf

Common Concerns

Will it hurt?

Pain after surgery is managed with medications and usually improves quickly.

Will I need another surgery later?

Modern implants last 15–20 years or more, depending on your age and activity level.

What are the risks?

Like any surgery, there are risks—such as infection, blood clots, or implant issues—but these are rare, especially when done by experienced surgeons in accredited hospitals.

Final Thoughts

Knee replacement isn’t just about improving a joint. It’s about restoring your independence, mobility, and peace of mind.

If knee pain is affecting your daily life, don’t wait. Talk to a specialist to explore your options and determine the best path forward.
