Do I Need a Knee Replacement Yet? Why the Answer Is Sometimes No

Knee pain can make ordinary tasks exhausting. Walking to the shops, using stairs or getting through a day at work may become harder. For some people, that leads to a question: is it time for a knee replacement?

According to Joint Vision orthopaedic surgeon Dr Anil Goudar, the answer depends on the cause of the pain, its effect on everyday life and the treatment already tried.

A specialist appointment is an opportunity to understand those options. It does not automatically lead to surgery.

Looking beyond the scan

Dr Goudar considers the patient's symptoms and examination alongside imaging where appropriate. He also asks what they can do now and what they hope treatment will help them return to.

“That's why all my notes do have what their hobbies are,” he said.

The discussion might involve work, walking, caring for family or sport. Two people with similar changes on an X-ray may have different symptoms, goals and treatment needs.

Australia's Osteoarthritis of the Knee Clinical Care Standard supports this broader assessment, including the effect of symptoms on activities and quality of life.

Considering care before replacement

For knee osteoarthritis, recommended non-surgical care includes education, suitable exercise, weight management where appropriate and individually assessed medicines for symptom relief.

Dr Goudar wants patients to understand what they have tried, whether it has helped and what further support might be useful. Physiotherapy or exercise physiology may help them build a program they can manage. Nutrition support may be relevant for some patients.

The purpose is to find a workable way to manage symptoms and maintain function. It also helps clarify whether surgery is the appropriate next step.

Why an active patient's goals matter

Someone hoping to return to demanding sport needs a careful discussion about what replacement can and cannot offer.

Dr Goudar describes situations in which a person is still active despite knee arthritis and may be better served, at that stage, by non-surgical care. He also explains that some activities may need to change after replacement.

“The knee replacement is not a magic fix,” he said.

That does not dismiss the patient's pain. It recognises that surgery has benefits, risks and limitations that need to be weighed against the person's goals.

When replacement becomes an option

Knee replacement may be considered when severe pain or loss of function persists despite appropriate non-surgical management. The decision should include the likely benefits, surgical risks, recovery requirements and the patient's preferences.

Dr Goudar explains that the history, examination and relevant imaging need to make sense together. The discussion also covers the person's general health and their ability to manage the recovery ahead.

For younger patients, he spends time explaining longer-term considerations, including the possibility of further surgery during their lifetime. Age alone does not settle the decision.

When to seek advice

You do not need to wait until you have decided on surgery before asking for help. If knee pain is affecting your mobility, sleep or daily activities, a GP assessment can help identify the cause and the next step.

If symptoms continue despite treatment, specialist advice may help clarify the options. Sometimes that leads to a plan for replacement. Sometimes it leads to a different approach and a review later.

At Joint Vision, Dr Goudar provides assessment and surgical and non-surgical care for hip and knee conditions. Speak with your GP about a referral if you would like to discuss your options.
