Frequently asked questions about Knee Replacement Surgery

1. When is knee replacement surgery necessary?
Knee replacement is recommended when severe knee pain, stiffness, or loss of function—often due to arthritis or injury—does not improve with medications, physical therapy, or other non-surgical treatments.

2. Can I avoid surgery?
Non-surgical treatments such as physical therapy, weight loss, medications, and injections are always considered first. Surgery is only advised if these options fail to relieve symptoms and your quality of life is significantly affected.

3. What happens during knee replacement surgery?
During the procedure, damaged surfaces of the knee joint are removed and replaced with artificial implants. The surgery typically takes 60–90 minutes.

4. What are the risks and complications?


All surgeries carry some risks. For knee replacement, these include infection, blood clots, implant loosening or failure, nerve injury, and the rare need for revision surgery. Serious complications are uncommon.

5. Is the surgery painful?
Some pain is expected after surgery, but modern anesthesia and pain management techniques help keep discomfort under control. Most patients notice significant pain relief as they recover.

6. How long is the recovery period?
Most patients are able to walk with support within a day or two after surgery. Full recovery and return to normal activities usually take 3–6 months.

7. When can I start physiotherapy?
Physiotherapy typically begins within a day or two after surgery to help restore movement and strength in the knee.

8. What activities can I do after knee replacement?
After recovery, you can return to low-impact activities like walking, cycling, and swimming. High-impact sports are generally discouraged to protect your new joint.

9. How long does the artificial knee last?
Most knee implants last 15–20 years or longer, depending on your activity level and overall health.

10. What should I expect immediately after surgery?
You may feel drowsy from anesthesia and have your knee elevated. You will receive medications to prevent blood clots and infection. Some pain and swelling are normal and will be managed by your care team.

11. What special equipment will I need at home?
You may need a walker or crutches for support during early recovery. It is also helpful to arrange for assistance at home for the first few weeks.

12. How much does knee replacement surgery cost?
Costs vary depending on the hospital, type of implant, and your insurance coverage. Please contact our hospital for a detailed estimate.
