Physiotherapy or Surgery for Knee Pain: What Should You Try First?

“My doctor says I need a knee operation. Should I try physiotherapy first?”

I hear this question almost every week in my practice in Ahmedabad. It is a big decision, and it deserves a clear, honest answer. In this article I explain what international guidelines recommend, who usually benefits from surgery, what physiotherapy can and cannot do, and how to make the right choice with your doctor.

Please note: I am a physiotherapist, not a surgeon. The final decision about surgery should always be made with your orthopaedic doctor. My aim is to help you understand your options so you can have a better conversation with them.

What causes most knee pain in adults?

In adults over 45, the most common cause of long term knee pain is osteoarthritis. Over time, the smooth cartilage at the ends of the bones becomes thinner, the joint lining can become irritated, and small bony changes develop. The knee may become painful, stiff and sometimes swollen.

Other causes include meniscus tears, ligament injuries, pain behind the kneecap and inflammatory arthritis such as rheumatoid arthritis. The right treatment depends on the cause, which is why a proper assessment matters.

What do the guidelines say?

The National Institute for Health and Care Excellence (NICE) in the United Kingdom reviews research and sets treatment guidelines that are widely respected around the world. For osteoarthritis, NICE recommends that everyone should be offered:

1. Therapeutic exercise, tailored to the person, such as strengthening and general fitness exercise
2. Education about the condition and how to manage it
3. Weight management advice for people who are overweight

These are called “core treatments”. They are recommended for everyone, at every stage, before and alongside other treatments.

Joint replacement surgery is considered for people whose symptoms have a substantial impact on their quality of life, and when non surgical treatments have not helped enough.

What physiotherapy can do

A good physiotherapy programme for knee osteoarthritis usually includes strengthening of the thigh and hip muscles, exercises to improve knee movement, balance training, hands on therapy to ease pain and stiffness, and advice on daily activities.

Research shows that this kind of programme can:

• Reduce pain
• Improve walking, stair climbing and the ability to get up from a chair or the floor
• Improve confidence and quality of life
• Delay, and in some cases avoid, the need for surgery

Physiotherapy works best when you are an active partner. Most of the benefit comes from the exercises you do regularly at home, guided and progressed by your physiotherapist.

What physiotherapy cannot do

It is important to be honest. Physiotherapy cannot regrow cartilage or reverse the changes you see on an X-ray. When the joint is very badly damaged and pain is severe even at rest or at night, exercise alone may not be enough. In those situations, a knee replacement can be a very good option.

Who usually benefits from surgery?

Your surgeon may recommend knee replacement if:

• Pain is severe and present most days, including at night
• Walking distance is very limited despite good non surgical care
• The knee has become badly deformed, for example very bowed
• Daily activities such as bathing, dressing and using the toilet have become very difficult
• You have tried exercise based physiotherapy properly and it has not helped enough

Surgery is a major operation with real benefits and some risks, and recovery takes several months. Your surgeon will consider your age, general health, other medical conditions and your goals.

Why trying physiotherapy first makes sense for many people

1. It is recommended first line care. Guidelines suggest exercise for everyone with osteoarthritis.
2. It helps either way. If you later need surgery, being stronger before the operation can make recovery easier.
3. It is low risk. When planned carefully, exercise has very few side effects.
4. It puts you in control. You learn how to manage your knee day to day.

A practical way to decide

Here is a step by step approach that many of my patients find helpful:

1. Get a clear diagnosis from your doctor, including any X-ray or scan they recommend.
2. Start a structured exercise programme with a physiotherapist, usually for 6 to 12 weeks.
3. Track your progress. How far can you walk? How many stairs can you climb? How is your sleep? Keep a simple record.
4. Review with your surgeon. Share your progress. If you are improving, you may continue with physiotherapy. If pain and function remain severe, surgery may be the right next step.

Questions to ask your surgeon

• What is causing my knee pain?
• How severe is my arthritis, and how does that relate to my symptoms?
• What can I expect if I try exercise first?
• What are the benefits and risks of surgery for me?
• How long is the recovery, and what will physiotherapy after surgery involve?

What a good knee exercise programme looks like

If you decide to try physiotherapy first, make sure the programme includes:

• A proper assessment of your knee, hip, walking and daily activities
• Strengthening exercises for the thigh and hip muscles, progressed over weeks
• Exercises you can do at home, clearly explained
• Advice on activity and pacing, so you stay active without flare ups
• Regular measurement of pain, walking distance and function
• A long term plan, so you keep your knee strong after sessions end

A programme that relies only on machines or massage, without progressive exercise, is unlikely to give the full benefit that research shows.

When to see a physiotherapist

Book a physiotherapy assessment if:

• You have knee pain that has lasted more than a few weeks
• You have been told you have knee arthritis and want to know what you can do
• Your doctor has mentioned surgery and you want to try a structured exercise programme first
• You are already booked for surgery and want to prepare your muscles
• You have had surgery and need rehabilitation

Warning signs that need a doctor

See a doctor promptly if:

• Your knee becomes hot, red and very swollen, especially with fever
• You cannot bear weight after a fall or twist
• Your knee locks and will not straighten
• You have a painful, swollen calf
• Pain is severe and getting quickly worse

Keeping the conversation going

Share your exercise progress with your surgeon at each visit. Clear information about your pain, walking and daily activities helps you both make the best decision.

Key points to remember

• Exercise, education and weight management are the recommended first treatments for knee osteoarthritis.
• Physiotherapy cannot change an X-ray, but it can reduce pain and improve walking for many people.
• Surgery is a good option when pain and disability stay severe despite good non surgical care.
• Decide together with your orthopaedic surgeon, using your progress as a guide.

The bottom line

For most people with knee osteoarthritis, a well planned physiotherapy programme is the recommended first step. It can reduce pain and improve walking for many people, and it prepares you well if surgery is needed later. Surgery is a good option for people with severe pain and disability despite good non surgical care. Work with both your surgeon and your physiotherapist to choose what is right for you.
