How Is Knee Osteoarthritis Diagnosed and When Should You Get a Scan?

FAQ Series — The Pain Relief Clinic Singapore

How is knee osteoarthritis diagnosed?
Diagnosis usually begins with a clinical history and physical examination. Common signs include:

• Joint pain during movement or weight-bearing
• Stiffness, especially in the morning
• Limited range of motion
• Clicking or grinding sounds
• Swelling around the knee

If your symptoms suggest arthritis, your doctor may recommend imaging for a clearer diagnosis.

What tests confirm knee osteoarthritis?
The most common diagnostic tools include:

✅ X-rays – The basic scan to check for joint space narrowing, bone spurs, or bone changes. At The Pain Relief Clinic, a knee X-ray costs $50 and can be done same-day.

✅ MRI Scans – MRI is the gold standard for detecting early cartilage wear, meniscus damage, and soft tissue issues. Private MRI scans can be arranged within 1 working day at prices from $950 and below.

✅ Ultrasound – Useful for detecting swelling, fluid build-up, or soft tissue abnormalities.

When should I get a knee scan?
You should consider a scan if:

• Your knee pain persists for more than 2 weeks despite treatment
• Your condition is worsening or affecting daily activities
• You’ve had previous injuries or surgery
• You’re unsure if arthritis is the actual cause
• There’s swelling, stiffness, or clicking sounds that don’t improve
• You need a clearer diagnosis before starting treatment

Can I use insurance or Medisave for scans?
Yes. Many patients use:

• Integrated Shield Plans (via Medisave) to subsidize imaging costs
• Employer outpatient benefits
• Personal accident insurance (if due to injury)
• Travel insurance (for sudden knee pain while on holiday)

We can help with the paperwork—just let us know your coverage and forms needed.

Why is early diagnosis important?
Delaying proper diagnosis can worsen joint damage and make surgery more likely later. Getting the right scan early helps you receive more effective non-invasive treatment options and avoid unnecessary suffering.
