Question 1

What conditions can knee replacement surgery treat?

Accepted Answer

Knee replacement surgery effectively treats conditions such as osteoarthritis, rheumatoid arthritis, and post-traumatic arthritis, which cause chronic pain, stiffness, and reduced mobility that significantly impact daily activities.

Question 2

Who is a candidate for knee replacement surgery?

Accepted Answer

Candidates are individuals with severe knee pain and dysfunction that do not improve with non-surgical treatments, such as physiotherapy, medications, injections, or lifestyle modifications.

Question 3

What is the difference between total and partial knee replacement?

Accepted Answer

• Total Knee Replacement (TKR): The entire knee joint is replaced with a prosthetic joint.
 • Partial Knee Replacement (PKR): Only the damaged portion of the knee is replaced, preserving healthy bone and tissue. PKR typically offers quicker recovery and a more natural knee movement compared to TKR.
Your suitability depends on the extent of knee damage.

Question 4

How is robotic-assisted surgery used in knee replacements?

Accepted Answer

Robotic-assisted knee surgery provides greater precision in implant placement and alignment, enhancing the longevity and functionality of the prosthetic joint. This technology is tailored to individual patients' anatomy for optimal outcomes.

Question 5

What happens during a knee replacement procedure?

Accepted Answer

The damaged cartilage and bone are removed and replaced with metal and plastic prosthetic components, restoring joint function and reducing pain. The procedure can be performed using traditional or minimally invasive techniques.

Question 6

How long does recovery from knee replacement take?

Accepted Answer

• Day of surgery: Mobilisation typically begins.
 • Within 2–3 days: Most patients are discharged.
 • 6–8 weeks: Patients return to daily activities and low-impact exercises.
 • Several months: Full recovery, including strength and range of motion, may be achieved.

Question 7

Will I need physiotherapy after knee replacement surgery?

Accepted Answer

Yes, physiotherapy is essential to regain strength, flexibility, and function in the knee. A personalised rehabilitation programme will help you achieve the best results.

Question 8

How can I reduce the risk of complications after knee surgery?

Accepted Answer

To minimise risks such as infection, blood clots, or implant issues:
 • Follow your surgeon’s advice on wound care and activity levels.
 • Participate in physiotherapy and avoid high-impact activities that could stress the joint.

Question 9

What are the potential risks of knee replacement surgery?

Accepted Answer

Though rare, risks include infection, blood clots, nerve damage, or implant wear. Your surgeon will discuss these in detail and take precautions to ensure a safe recovery.

Question 10

How long do knee replacements last?

Accepted Answer

Most knee replacements last 15–20 years or more, depending on factors like implant type, surgical technique, and post-operative care.

Question 11

What should I do if my knee pain persists after surgery?

Accepted Answer

Persistent pain may indicate issues such as implant misalignment, scar tissue formation, or unrelated conditions like bursitis. A follow-up consultation and imaging studies can help identify and address the underlying cause.

Question 12

What activities can I resume after knee replacement?

Accepted Answer

Low-impact activities such as walking, swimming, and cycling are encouraged. High-impact activities should generally be avoided to preserve the longevity of the implant. Your surgeon will provide personalised guidance.

Question 13

Are there alternatives to knee replacement surgery?

Accepted Answer

Non-surgical treatments, such as weight management, physiotherapy, anti-inflammatory medications, and joint injections, can manage symptoms in the early stages of joint degeneration. These should be explored before surgery if appropriate.
