AI Guided Decision on Knee Arthritis
Total Knee Replacement or Nonsurgical Treatment?
The decision to proceed with a total knee replacement is a major one. This tool uses artificial intelligence to help you understand whether you may benefit from knee replacement surgery. All you need to do is answer a set of questions and upload an X-ray of your knee — and you get your answer instantly.

Frequently Asked Questions
Do I need knee replacement surgery?
Whether you need knee replacement depends on the severity of your arthritis, your symptoms, and how much they affect daily life. This assessment tool evaluates these factors using a validated scoring system and AI-based X-ray analysis to guide your decision.
How do I know if I need knee replacement?
Key indicators include persistent knee pain during daily activities, difficulty climbing stairs or squatting, limited relief from nonsurgical treatments, and moderate-to-severe arthritis visible on X-ray. This tool helps assess all of these factors together.
How is knee arthritis severity graded from an X-ray?
Knee arthritis is graded using the Kellgren-Lawrence (KL) scale from 0 to 4, where 0 means no arthritis and 4 indicates severe osteoarthritis. Our AI model analyses your knee X-ray and assigns a KL grade automatically, matching the accuracy of trained radiologists.
Am I a candidate for knee replacement?
Knee replacement eligibility depends on your age, symptom severity, knee mobility, and X-ray findings. This assessment considers all these factors to determine whether total knee replacement may be appropriate, uncertain, or not currently recommended for you.
What are the alternatives to knee replacement?
Nonsurgical treatments for knee arthritis include physiotherapy, weight management, pain medications, knee braces, steroid injections, and lifestyle modifications. These may be more appropriate if your arthritis is mild to moderate or your symptoms are manageable.
What kind of X-ray should I upload?
Upload a single AP (front-view) knee X-ray taken in a standing position. Standing X-rays give the most accurate arthritis grading. Avoid MRI scans, lateral views, or images of both knees together.
Is this assessment a substitute for consulting a doctor?
No. This tool provides AI-guided guidance to support your decision-making, but it is not a diagnosis. A clinical examination and consultation with an orthopaedic surgeon are essential before making any decision about knee replacement surgery.
How accurate is the AI knee arthritis assessment?
The AI model used for X-ray grading was developed by Stanford University researchers and achieves 71% accuracy in Kellgren-Lawrence grading — matching or exceeding the accuracy of individual radiologists. The overall assessment combines this with a validated symptom scoring system.
