As a Senior Joint and Spine Surgeon, one of the most common procedures I perform is total knee replacement (TKR). Understandably, patients and their families often have several questions before making this important decision. In this article, I’ll address some of the most frequently asked questions to help you make an informed choice with confidence.
1. When do I really need a knee replacement?
Knee replacement is usually considered when:
- Severe arthritis causes constant pain even at rest
- Difficulty in walking, climbing stairs, or performing daily activities
- Stiffness and deformity of the knee joint
- No lasting relief from medications, physiotherapy, or injections
If your pain interferes with your quality of life, it may be time to discuss surgery.
2. Is knee replacement safe?
Yes. Knee replacement is one of the most successful orthopedic surgeries worldwide, with very high success rates. Advances in surgical techniques, anesthesia, and implant design have made it safer than ever. While, like any surgery, there are risks (infection, blood clots, stiffness), careful pre-operative evaluation and modern medical care minimize these risks.
3. How long does the artificial knee last?
Modern implants can last 15–20 years or more, depending on activity level, weight, and overall health. Many patients enjoy long-term relief and improved mobility after the procedure.
4. Will I be pain-free after surgery?
Most patients experience significant pain relief after recovery. Some initial discomfort is expected in the first few weeks due to surgical healing and physiotherapy, but this improves steadily. The goal is to let you walk comfortably, climb stairs, and enjoy a better quality of life.
5. How soon can I walk after knee replacement?
In most cases, patients are encouraged to stand and walk with support within 24 hours after surgery. Early mobilization reduces complications and speeds recovery.
6. What is the recovery period like?
- Hospital stay: Usually 3–5 days
- Walking with support: Within 1–2 days
- Stitches removal: After 2 weeks
- Driving: Around 4–6 weeks
- Resuming most daily activities: By 6–8 weeks
- Full recovery: Around 3 months, though improvement continues up to a year
7. Can both knees be replaced at the same time?
Yes, if the patient is medically fit, simultaneous bilateral knee replacement can be done. It has the advantage of one-time anesthesia and a single recovery period. However, in elderly or higher-risk patients, staged surgeries may be safer.
8. Will I be able to do all normal activities after surgery?
Yes. You will be able to walk, climb stairs, do household chores, and even enjoy light recreational activities like cycling, swimming, or golf. High-impact sports such as running or jumping are usually discouraged to prolong implant life.
9. Is knee replacement the only option?
No. Non-surgical treatments such as physiotherapy, lifestyle changes, medications, and injections may still provide relief in early to moderate arthritis. Surgery is recommended only when these methods no longer help.
10. What can I do to ensure the best results?
- Maintain a healthy weight
- Follow your physiotherapy program diligently
- Avoid high-impact activities
- Regular check-ups with your surgeon
