Understanding Knee Osteoarthritis
Osteoarthritis is the gradual wear of the protective cartilage that cushions the knee joint. As cartilage thins, the joint surfaces become irritated, causing pain, stiffness and reduced mobility.
Common Symptoms
- Pain that worsens with activity and eases with rest
- Morning stiffness that improves with movement
- Swelling and a feeling of warmth
- Reduced walking distance and stiffness after sitting
Common Causes
- Age-related cartilage wear
- Previous knee injury (e.g. meniscus or ACL)
- Excess body weight increasing joint load
- Repetitive occupational stress on the knee
How Assessment Works
Assessment includes a history of symptoms, examination of the joint and weight-bearing X-rays to evaluate the degree of cartilage loss and joint space narrowing.
Treatment Options
- Physiotherapy, exercise and activity modification
- Weight management to reduce joint load
- Ultrasound-guided injections for symptom relief
- PRP and regenerative therapies (where appropriate)
- Joint replacement for advanced arthritis
When to Seek Specialist Care
If knee osteoarthritis is limiting your daily activities, disturbing sleep, or no longer responding to self-management, a specialist assessment can help review your options.
Frequently Asked Questions
Can knee osteoarthritis be cured?
Osteoarthritis cannot be cured, but symptoms can often be effectively managed. Treatment aims to reduce pain, improve function and delay progression.
When is knee replacement considered?
Knee replacement is typically considered when arthritis significantly limits daily life and non-surgical options are no longer sufficient. A specialist advises on timing and suitability.
