Age-related degeneration
The cartilage gradually becomes thinner and the joint may develop degenerative changes.
Knee Arthritis
Knee pain is not always simply “wear and tear”
Knee arthritis occurs when the structures that allow the joint to move smoothly become damaged or progressively degenerated.
Osteoarthritis is the most common form, but knee pain can also occur because of previous injuries, inflammatory arthritis, cartilage damage, meniscal pathology or other conditions.
The important first step is to determine what is actually causing the pain rather than assuming that every painful knee needs a replacement.
Common symptoms of knee arthritis
You may experience:
- Pain while walking or standing
- Pain when climbing or descending stairs
- Difficulty getting up from a chair
- Morning or start-up stiffness
- Swelling
- Reduced knee movement
- Difficulty squatting
- Pain after prolonged activity
- Gradually decreasing walking distance
- Difficulty performing previously comfortable activities
Symptoms often develop gradually, although arthritis can become noticeable after an injury or period of increased activity.
What causes knee arthritis?
Several factors can contribute:
Previous injury
Fractures, ligament injuries and meniscal injuries can increase the risk of later arthritis.
Abnormal alignment
Varus or valgus alignment can alter load distribution across the knee.
Inflammatory arthritis
Conditions such as rheumatoid arthritis can damage the knee.
Previous surgery
Certain previous knee injuries or procedures may contribute to later degenerative changes.
Other factors
Body weight, activity level, genetics and metabolic health can also influence symptoms and disease progression.
How is knee arthritis diagnosed?
Diagnosis combines your symptoms with a physical examination and appropriate imaging.
Assessment may include:
- Knee alignment
- Range of motion
- Stability
- Joint-line tenderness
- Muscle strength
- Gait
- Hip and ankle examination where relevant
Does knee arthritis always require surgery?
No. Treatment depends on the severity of symptoms and their impact on your life.
AAOS clinical guidance supports exercise-based management and sustained weight loss for appropriate patients with symptomatic knee osteoarthritis, while treatment should be individualised rather than applied as a fixed protocol.
Non-operative management may include
- Exercise and strengthening
- Physiotherapy
- Weight management when appropriate
- Activity modification
- Walking aids when required
- Bracing in selected patients
- Appropriate pain medication
- Selected injections
When is knee replacement considered?
Knee replacement may be considered when:
- Arthritis is advanced
- Pain remains significant despite appropriate non-operative treatment
- Daily activities are substantially affected
- Walking capacity is reduced
- Sleep or quality of life is affected
- Imaging and clinical findings correspond with the symptoms
The decision should be based on the patient’s symptoms and functional limitation together with the clinical and radiological findings, rather than an X-ray alone.
What are the surgical options?
Depending on the pattern of arthritis and the individual patient, surgical options can include:
- Joint-preserving procedures in selected cases
- Partial knee replacement in appropriately selected patients
- Total knee replacement
There is no single operation that is appropriate for every arthritic knee.
Frequently Asked Questions
Can knee arthritis be reversed?
Established cartilage loss cannot simply be reversed with exercise or medication, but symptoms and function can often be improved substantially with appropriate treatment.
Does everyone with bone-on-bone arthritis need knee replacement?
The X-ray is only one part of the decision. Symptoms, function, examination and individual circumstances matter.
Is walking bad for knee arthritis?
Appropriately dosed physical activity is generally an important part of managing knee osteoarthritis. Activities may need to be modified according to symptoms.
Can weight loss help knee arthritis?
For patients who are overweight or obese, sustained weight loss can improve pain and function.
Does a knee MRI tell me whether I need surgery?
Not by itself. MRI findings need to be interpreted alongside symptoms and examination.
Consultation
Persistent knee pain deserves a diagnosis—not simply a label of “arthritis.”
