Knee Arthritis

Symptoms, Diagnosis & Treatment Options

Osteoarthritis of the knee is gradual wear of the joint’s smooth cartilage. It is common — and there is a great deal that can be done, long before surgery.

Osteoarthritis is the gradual breakdown of the smooth articular cartilage that caps the ends of the bones in your knee. As this cushion thins, the bones move less freely, and over time the joint becomes stiff and painful.

Clinical examination

2. Signs & Symptoms

Pain — that worsens with activity and eases with rest — though advanced cases ache at rest too.

Diagnostic imaging

3. Diagnosis & Imaging

Diagnosis combines your history, an examination of movement and alignment, and standing (weight-bearing) X-rays that show joint-space narrowing.

Treatment

4. Treatment Options

Treatment follows a ladder — always starting with the least invasive measures, which control symptoms effectively for many years in most patients.

Rehabilitation

5. Recovery & Rehabilitation

Knee arthritis is managed rather than cured, and a clear plan makes a real difference.

“ Clinical Note from Dr. Yousef Muhammad

Surgery is the last step on the ladder, not the first. For most patients, years of good function come from movement, strength and weight — not the operating theatre.

Frequently Asked Questions

What are the symptoms of Knee Arthritis?

Pain — that worsens with activity and eases with rest — though advanced cases ache at rest too. Stiffness — especially in the morning or after sitting, easing as you move. Swelling — and a feeling of warmth in the joint. Grinding or clicking — (crepitus) as the roughened surfaces move. Reduced range of motion — and difficulty with stairs, kneeling or long walks.

What causes Knee Arthritis?

Age — cartilage naturally becomes less resilient over time. Previous injury, such as an old ACL or meniscus tear. Excess body weight, which multiplies the load through the knee. Genetics and family history. Repetitive high-impact loading over many years.

How is Knee Arthritis diagnosed?

Diagnosis combines your history, an examination of movement and alignment, and standing (weight-bearing) X-rays that show joint-space narrowing. MRI is occasionally used to assess cartilage and rule out other causes of pain.

How is Knee Arthritis treated?

Treatment follows a ladder — always starting with the least invasive measures, which control symptoms effectively for many years in most patients. Activity & weight: Targeted exercise, muscle strengthening and weight management are the most powerful, best-evidenced treatments. Medication: Anti-inflammatory medication and, in selected cases, injections to control flare-ups. Physiotherapy & aids: Bracing, footwear and physiotherapy to offload the joint and improve mechanics. Joint replacement: When conservative care no longer controls pain, partial or total knee replacement reliably restores comfort and mobility.

How do I live well with Knee Arthritis?

Knee arthritis is managed rather than cured, and a clear plan makes a real difference. Staying active — within comfortable limits — keeps the surrounding muscles strong and the joint mobile. When the time for surgery does come, modern joint replacement offers excellent, durable results.
