7 Questions to Ask Before Knee Replacement Surgery
MBBS, D'Ortho, DNB (Orthopedics), MNAMS (Orthopedics), FIJR (Robotic & Navigation)
A knee replacement consultation should help you make an informed decision. Before comparing implants or robotic systems, ask whether your symptoms and diagnosis justify surgery, what alternatives remain, and what recovery would involve.

1. What Is Causing My Knee Pain?
Ask your surgeon to explain your diagnosis and how your examination findings and any relevant imaging relate to your symptoms. Describe the activities you have stopped, how far you can walk, whether you have difficulty climbing stairs, and whether pain disturbs your sleep.
Bring previous reports and a list of treatments you have tried. An X-ray provides useful information, but the decision should also reflect your symptoms and daily function.
2. Is It Time to Consider Knee Replacement?
NICE recommends considering referral when osteoarthritis substantially affects quality of life and suitable non-surgical management is ineffective or unsuitable. Referral is an opportunity for assessment, not a commitment to an operation.
Ask what factors would make surgery more appropriate and how your progress will be reviewed if you continue non-surgical care. Your decision should consider your symptoms, daily limitations, treatment history, and personal preferences.
3. Which Non-Surgical Options Are Still Appropriate?
Therapeutic exercise, education, and weight management when appropriate are core parts of osteoarthritis care. Ask whether your exercise programme needs supervision or adjustment and which pain-relief options are suitable for your medical history.
If an injection is proposed, ask about its purpose, expected duration of benefit, supporting evidence, and potential risks.
For a discussion of one blood-derived injection option, read the GFC patient-selection guide. Injection decisions require individual assessment, and suitability should not be assumed without discussing the available evidence and alternatives with your clinician.
4. Why Total or Partial Knee Replacement?
Ask why the recommended operation is appropriate for your particular knee. Request an explanation of the areas affected by joint damage, knee stability, alignment or deformity, and available alternatives.
Total and partial knee replacement are not suitable for every patient in the same way. A procedure that helped a friend may not be appropriate for you, so ask your surgeon to explain the reasoning behind the recommendation.
5. What Would Robotic Assistance Change?
Ask which system would be used, how it assists with surgical planning or execution, whether additional imaging is needed, and what additional costs may apply.
Robotic assistance does not remove the need for a surgeon or guarantee a better result. AAOS guidance reports no significant short-term difference in function, outcomes, or complications between robotic-assisted and conventional total knee replacement, while noting differences between the systems studied.
Ask how that evidence applies to the proposed procedure and what specific benefit your surgeon expects the technology to provide in your case.
6. What Are My Personal Risks and Recovery Needs?
Knee replacement has potential risks, including infection, blood clots, stiffness, and persistent pain. Ask how your health conditions and medicines may affect surgical preparation, and request clear instructions about rehabilitation, follow-up, and symptoms that should prompt medical attention.
Discuss the support you may need at home and the activities you hope to resume. Recovery varies from person to person, so a fixed promise about walking, pain relief, or returning to work is not a substitute for an individual recovery plan.
7. What Will the Complete Treatment Cost?
Request a written estimate covering the hospital stay, implant, professional fees, any robotic assistance charges, rehabilitation, and follow-up. Ask what is excluded and how insurance approval is handled.
If you compare estimates from different hospitals, check whether the same services are included. A clinical recommendation and a financial estimate answer different questions, and both should be clear before you schedule surgery.
✅ Bring a Short Decision Checklist
Write down your main goal, diagnosis, proposed treatment, reasonable alternatives, personal risks, and follow-up plan. Ask for clarification or consider a second opinion if any part remains unclear.
Frequently Asked Questions
1. When should I consider knee replacement surgery?
Knee replacement may be considered when osteoarthritis substantially affects quality of life and appropriate non-surgical treatments are ineffective or unsuitable. An orthopaedic surgeon can assess whether it is appropriate for your circumstances.
2. Is an X-ray enough to decide whether I need knee replacement?
No. X-rays provide useful information about joint changes, but your symptoms, physical examination, daily function, and treatment history should also inform the decision.
3. Can knee pain be managed without surgery?
Depending on the cause and severity, treatment options may include therapeutic exercise, education, weight management when appropriate, and suitable pain-relief treatments. The best approach depends on your individual condition.
4. Should I try injections before knee replacement?
Ask your clinician whether an injection is appropriate, what evidence supports it, how long any benefit might last, and what risks apply. Not every injection is suitable for every patient, and injections should not automatically be considered a substitute for surgery.
5. What is the difference between total and partial knee replacement?
Total knee replacement addresses the main joint compartments, while partial knee replacement treats a more limited area of damage. The appropriate option depends on the extent and location of joint damage, knee stability, and other clinical findings.
6. Does robotic knee replacement guarantee better results?
No. Robotic assistance does not guarantee better outcomes. Ask your surgeon about the evidence for the proposed system, its expected benefits in your case, and whether any additional costs are justified.
7. What are the risks of knee replacement surgery?
Potential risks include infection, blood clots, stiffness, persistent pain, and implant-related complications. Your surgeon should explain how your medical history and other individual factors may affect your risk.
8. How long does recovery take after knee replacement?
Recovery varies according to individual health, the procedure, and rehabilitation. Ask your surgical team for a personalised recovery plan and guidance on when you may resume specific activities.
9. What costs should I ask about before surgery?
Request a written estimate covering the hospital stay, implant, professional fees, robotic assistance if applicable, rehabilitation, and follow-up. Also clarify insurance coverage, exclusions, and any likely additional expenses.
10. Should I get a second opinion before knee replacement?
A second opinion can help you understand your diagnosis, alternatives, surgical options, and expected recovery if you remain uncertain about the recommendation. It can also help clarify whether further non-surgical treatment is reasonable.
