By Mr Raman Sethi – Expert Orthopaedic in Melbourne
Knee arthritis is one of the most common causes of chronic knee pain and reduced mobility. It can make everyday activities such as walking, climbing stairs, getting out of a chair, or even enjoying a favourite hobby more difficult. While many people assume that arthritis automatically means surgery, I’ve found that’s rarely the case. In many situations, symptoms can be managed successfully with non-surgical treatments, particularly when diagnosed early.
I’m Mr Raman Sethi, an orthopaedic surgeon in Melbourne, and one of the questions I hear most often is, “Do I need surgery for my knee arthritis?” The answer depends on several factors, including the severity of the arthritis, your symptoms, your lifestyle, and the extent to which the condition affects your quality of life. My approach is to explore the most appropriate treatment options for each individual’s needs, starting with conservative management whenever possible.
This guide explains how knee arthritis develops, the available treatment options, and when surgery may be the most suitable option.
What Is Knee Arthritis?
The knee is one of the largest and hardest-working joints in the body. It relies on smooth cartilage to allow the bones to move against one another without friction.
Knee arthritis occurs when this protective cartilage gradually wears away. As the cartilage thins, the bones begin to rub together, leading to pain, stiffness, swelling, and reduced mobility.
The most common type is osteoarthritis, which develops over time due to age, previous injuries, genetics, or repeated stress on the joint. Other forms, such as rheumatoid arthritis, result from autoimmune conditions that affect the joint lining.
In my experience, patients often notice subtle symptoms at first, such as stiffness after sitting for long periods or discomfort when walking longer distances. These symptoms may gradually become more frequent as the condition progresses.
Common Symptoms of Knee Arthritis
Every patient experiences knee arthritis differently, but some of the most common symptoms include:
- Persistent knee pain
- Morning stiffness
- Swelling around the joint
- Reduced flexibility
- Clicking or grinding sensations
- Difficulty climbing stairs
- Pain after physical activity
- Reduced walking distance
- Knee instability
During consultations, I often ask patients how their symptoms affect everyday activities rather than focusing only on pain. Understanding how arthritis impacts work, exercise, sleep, and independence helps determine the most appropriate treatment plan.
Diagnosing Knee Arthritis
Effective treatment begins with a precise diagnosis.
I recommend seeking an assessment if knee pain persists for several weeks or begins limiting your daily activities.
Diagnosis usually involves:
- A detailed discussion about your symptoms
- Physical examination
- X-rays
- MRI scans when appropriate
These investigations help determine the severity of cartilage wear and whether other knee conditions may also be contributing to your symptoms.
Treatment of Knee Arthritis Without Surgery
One of the biggest misconceptions about arthritis is that surgery is inevitable.
I’ve found that many patients achieve significant improvement without an operation, particularly when treatment begins before severe joint damage develops.
Education and Lifestyle Changes
Understanding your condition is an important part of treatment.
I encourage patients to remain active while avoiding activities that place excessive stress on the knee.
Simple changes may include:
- Choosing low-impact exercise
- Reducing prolonged standing
- Wearing supportive footwear
- Modifying daily activities
Small adjustments often make a noticeable difference in managing symptoms.
Physiotherapy
One of the best non-surgical therapies for knee arthritis is physiotherapy.
Strengthening the muscles surrounding the knee improves stability and reduces pressure on the joint.
A physiotherapist may recommend exercises that improve:
- Strength
- Flexibility
- Balance
- Walking pattern
- Joint mobility
In my experience, patients who consistently follow their rehabilitation program often experience better long-term outcomes than those who rely solely on medication.
Weight Management
The strain on the knee joint might be reduced by even a small amount of weight loss. The forces acting through the knee during walking increase with each kilogram of body weight.
For patients who are overweight, gradual weight reduction can significantly improve pain and mobility while slowing the progression of arthritis.
Pain Relief and Anti-Inflammatory Medication
Medication can help control symptoms while patients continue with rehabilitation.
Options may include:
- Paracetamol
- Anti-inflammatory medication
- Topical gels
- Prescription medications, where appropriate
Medication should always be used under medical guidance, particularly for long-term management.
Injection Therapy
Some patients may benefit from injections when symptoms are not adequately controlled with physiotherapy and medication.
These may include:
- Corticosteroid injections
- Hyaluronic acid injections
- Platelet-rich plasma (PRP) in selected cases
During consultations, I often explain that injections are designed to manage symptoms rather than cure arthritis. Their effectiveness varies depending on the individual and the stage of joint degeneration.
When Is Surgery Considered?
Surgery is generally considered when conservative treatments no longer provide adequate relief.
I recommend discussing surgical options if:
- Pain significantly limits daily activities
- Walking becomes increasingly difficult
- Sleep is regularly interrupted by knee pain
- Physiotherapy and medication are no longer effective
- Quality of life continues to decline
The decision is never based solely on X-rays. Your symptoms, activity level, overall health, and personal goals are equally important.
Is Knee Arthroscopy Suitable for Arthritis?
Many patients ask whether knee arthroscopy can treat arthritis.
A knee arthroscopy is a minimally invasive procedure that uses a tiny camera and specialised equipment to examine and treat specific issues within the knee through tiny incisions.
I’ve found that there is often confusion about its role in arthritis treatment.
While knee arthroscopy can be very effective for conditions such as meniscal tears, loose cartilage fragments, or some sports injuries, it is generally not considered a treatment for advanced osteoarthritis itself. Current evidence indicates that arthroscopy offers limited benefit for most patients with established knee arthritis, unless another mechanical problem is causing symptoms.
Every case is different, which is why a thorough assessment is essential before recommending any procedure.
Minimally Invasive Knee Surgery
Advances in surgical techniques have made many procedures less disruptive than they once were.
When appropriate, minimally invasive knee surgery uses smaller incisions and specialised instruments to reduce tissue disruption.
Potential benefits may include:
- Smaller scars
- Reduced soft tissue damage
- Less post-operative discomfort
- Faster early recovery
- Earlier mobilisation
However, I always explain that not every patient is suitable for minimally invasive techniques. The most appropriate surgical approach depends on factors such as the severity of arthritis, knee anatomy, previous surgeries, and overall health.
Rather than just selecting the least invasive procedure, the objective is always to choose the safest and most effective one.
Knee Replacement Surgery
Knee replacement surgery may be advised when arthritis worsens and non-surgical therapies are no longer effective.
To restore movement and reduce pain, damaged joint surfaces are replaced with prosthetic components during this operation.
Depending on the extent of arthritis, surgery may involve:
In my experience, patients who undergo surgery following thorough evaluation and practical planning frequently experience significant improvements in quality of life, mobility, and discomfort.
Recovery After Knee Surgery
Recovery does not end once the operation is complete.
Since recovery is crucial to achieving the best possible outcome, I urge patients to actively engage in their rehabilitation.
Recovery typically includes:
- Physiotherapy
- Strengthening exercises
- Walking programs
- Swelling management
- Gradual return to normal activities
The time it takes each person to recover varies based on their unique health and the type of surgery they had.
Patience and consistency are essential throughout the rehabilitation process.
Can Knee Arthritis Be Prevented?
Although arthritis cannot always be prevented, healthy lifestyle choices may reduce the risk or slow its progression.
These include:
- Maintaining a healthy weight
- Staying physically active
- Building muscle strength
- Managing previous knee injuries properly
- Wearing appropriate footwear
- Avoiding repetitive high-impact activities when possible
I’ve found that early intervention often helps patients maintain mobility for longer and may delay the need for surgery.
When Should You See a Specialist?
Many people continue living with knee pain for months or even years before seeking professional advice.
I recommend arranging an assessment if you notice:
- Persistent pain lasting several weeks
- Increasing stiffness
- Swelling that repeatedly returns
- Difficulty walking
- Knee instability
- Pain affecting work, exercise, or sleep
Early assessment provides more opportunities to manage arthritis before significant joint damage occurs.
Common Mistakes to Avoid
Preparing well also means avoiding some common oversights.
I recommend avoiding these mistakes before your appointment:
- Forgetting previous scans or reports
- Leaving medication details at home
- Not mentioning previous surgeries
- Wearing restrictive clothing
- Forgetting to write down your questions
- Assuming surgery is the only treatment option
Accurate diagnosis can be greatly impacted by minute factors.
Concusion
Living with knee arthritis doesn’t mean giving up the activities you enjoy. With the right diagnosis and a personalised treatment plan, many people can successfully manage their symptoms and continue leading active, independent lives. I’ve found that the best outcomes come from understanding each patient’s goals and selecting treatments that match their individual needs, whether that’s physiotherapy, medication, injections, or surgery.
While procedures such as knee arthroscopy and minimally invasive knee surgery may play an important role for selected patients, they are only recommended when clinically appropriate. Every treatment decision should be based on a careful assessment rather than a one-size-fits-all approach.
If knee discomfort is negatively impacting your quality of life, I encourage you to book an appointment today for a comprehensive assessment. Whether you’re exploring non-surgical options or considering surgery, an experienced specialist can help you understand your diagnosis, discuss available treatments, and develop a personalised plan to support your long-term mobility.
