If you’re living with hip or knee osteoarthritis, deciding whether to consider a joint replacement can feel overwhelming. Here’s a clear, evidence-based way to think it through.

Surgery Is Usually the Second Step, Not the First

Clinical guidelines are consistent. Joint replacement is considered after non-surgical treatment has been properly tried and hasn’t given enough relief, not instead of it. A “proper try” generally means:

• Structured exercise, tailored to your joint. This is strongly supported for reducing pain and improving function.
• Education, so you understand what’s actually happening in your joint. “Wear and tear” is a poor description of osteoarthritis, and understanding this reduces distress and improves outcomes on its own.
• Weight management support, where relevant. Evidence shows this meaningfully improves pain and function.

If you haven’t had a genuine run at this, usually a properly supervised program over several months, is the place to start.

Signs Surgery May Be Worth Discussing

It’s worth speaking with your GP or a surgeon when:

• You’ve genuinely tried non-surgical care and it isn’t giving adequate relief.
• Pain is disabling and persistent. Most guidelines look for pain that’s interfered with function for at least three months.
• Imaging confirms moderate to severe joint damage and matches what you’re feeling.
• Your quality of life is genuinely limited: sleep, work, walking distance, the things that matter to you.

What Doesn’t Automatically Rule Surgery Out

• Carrying extra weight is not, on its own, a reason to delay surgery under current guidelines, though weight loss is still worth pursuing where possible.
• Age isn’t a hard cut off. Good candidacy is about overall health and joint findings, not a birthday.

The Bottom Line

Joint replacement works best as a considered decision after conservative care, not a shortcut around it. If you’re unsure where you sit on that pathway, a physio assessment can help answer that before you get to the surgeon’s door.
