Osteoarthritis of the Knee

Osteoarthritis of the knee is one of the most common causes of knee pain, stiffness, and reduced mobility, especially in adults over 40. At Sukumvit Physiotherapy and Rehabilitation Center, we provide evidence-based rehabilitation programs designed to reduce pain, improve joint function, and help patients maintain an active lifestyle.

What Is Knee Osteoarthritis?

Knee osteoarthritis is a degenerative joint condition that occurs when the protective cartilage cushioning the knee joint gradually wears down. As cartilage deteriorates, the bones may rub against each other, causing pain, swelling, and stiffness.
This condition typically develops slowly over time and may worsen without appropriate management.

Common Symptoms

Patients with knee osteoarthritis may experience:
• Pain during walking, standing, or climbing stairs
• Stiffness, especially in the morning or after rest
• Swelling around the knee
• Grinding or clicking sensation (crepitus)
• Reduced range of motion
• Weakness or instability
• Difficulty squatting or kneeling
Symptoms may fluctuate, with periods of increased discomfort during activity or weather changes.

Causes and Risk Factors

Several factors may increase the risk of developing knee osteoarthritis:
• Aging
• Previous knee injuries
• Obesity or excess body weight
• Repetitive knee stress
• Muscle weakness around the knee
• Poor joint alignment
• Family history

Why Early Treatment Is Important

Without proper management, knee osteoarthritis can lead to:
• Progressive joint degeneration
• Decreased mobility
• Muscle weakness
• Reduced independence
• Increased risk of falls
Early physiotherapy intervention can significantly slow progression and improve functional outcomes.

Conservative Management Is Effective

Research shows that structured physiotherapy and exercise are among the most effective first-line treatments for knee osteoarthritis. Surgery is usually considered only when conservative treatment fails to provide adequate relief.

Consult our physiotherapy team if you experience:
• Persistent knee pain
• Stiffness limiting daily activities
• Swelling that does not improve
