Knee Osteoarthritis: Symptoms, Diagnosis & Treatment
A clear, clinically structured guide to knee osteoarthritis—covering symptoms, diagnosis, treatment options, and when specialist care may help.
Treatment usually begins with
Physiotherapy & Strengthening
Pain Management
Weight & Lifestyle Management
Specialist Assessment
Most patients improve with non-surgical treatment. Surgery is considered only when appropriate after a thorough clinical assessment.
You may want an assessment if...
These symptoms may indicate that it's time to consult an orthopaedic specialist for a proper evaluation.
- Pain continues for more than a few weeks
- Walking or climbing stairs is becoming difficult
- The knee feels swollen, unstable, or stiff
- Earlier treatment is no longer providing relief
Early assessment can help identify the cause of your symptoms and guide the most appropriate treatment.
What is Knee Osteoarthritis?
Knee osteoarthritis is a gradual breakdown of the smooth cartilage that cushions the knee joint. As the joint changes, movement can become painful or stiff. Symptoms and progression vary, so treatment should always be based on a clinical assessment rather than an X-ray alone.
Common Concern
Pain during walking, standing, climbing stairs, or daily activities.
Often Manageable
Exercise, weight management and medicines may help
Surgery Isn't Always First
Knee replacement is recommended only for selected cases
Good to Know
Early assessment helps identify arthritis, ligament injuries, and meniscus problems.
Common Symptoms
- Pain during or after movement
- Morning stiffness
- Swelling or tenderness
- Grinding sensation
- Difficulty bending or straightening
- Walking and stair climbing harder
What Increases Your Risk
While aging is the most common contributor, a variety of mechanical, genetic, and lifestyle factors can play a significant role in cartilage thinning and joint degradation.
How It Is Diagnosed
An accurate assessment combines your personal physical experience with objective clinical and diagnostic findings.
1. Medical history
Discussion of symptoms, patterns, activity level, and previous injuries.
2. Physical examination
Evaluating range of motion, stability, alignment, and joint swelling.
3. Weight-bearing X-rays (when appropriate)
Visualizing joint space narrowing under actual gravity and loading.
4. MRI only when clinically indicated
Reserved for complex cases to assess ligaments, cartilage depth, or meniscus tears.
Treatment Approaches
Non-Surgical Care
- Physiotherapy
- Exercise
- Weight Management
- Pain Relief
- Lifestyle Modification
- Selected Injections
Surgical Care
When conservative therapies no longer offer adequate pain relief or function, partial or total knee replacement can restore mobility.
Treatment decisions are based on symptoms, clinical findings, imaging, lifestyle, and patient goals—not X-rays alone.
Know When to Act
Some symptoms can be monitored with a scheduled consultation, while others require immediate medical attention. Here's how to know the difference.
Book an Assessment
Schedule an orthopaedic consultation if your symptoms are affecting daily life or aren't improving.
- Pain persists for more than a few weeks
- Swelling keeps returning
- Knee feels unstable or gives way
- Walking, climbing stairs, or daily activities are becoming difficult
Seek Urgent Care
Visit the emergency department immediately if you experience any of the following symptoms.
- Major injury or accident
- Visible deformity of the knee
- Unable to bear weight
- Hot, swollen knee with fever
- Sudden severe pain or rapid swelling
