Arthritis: Causes, Symptoms and How Physiotherapy Can Help

Arthritis is the leading cause of joint pain and disability in Malaysia, affecting an estimated 15-20% of adults over 55. As the nation's population ages, the number of Malaysians living with arthritis is growing rapidly.

Whether it is stiff knees making it difficult to use the stairs, painful hands struggling to open a jar, or aching hips that limit your daily walks, arthritis can significantly impact quality of life. However, with the right physiotherapy approach, most people with arthritis can maintain active, fulfilling lives.

Types of Arthritis

While there are over 100 types of arthritis, two forms account for the vast majority of cases seen by physiotherapists in Malaysia:

Osteoarthritis (OA) is the most common form, affecting the cartilage that cushions the ends of bones within a joint. As this cartilage thins and wears, the underlying bone changes, and the joint becomes painful, stiff, and swollen.

It most commonly affects the knees, hips, hands, and spine. OA is not simply "wear and tear" – it is an active process involving the entire joint, including bone, cartilage, synovium, ligaments, and muscles.

Rheumatoid arthritis (RA) is an autoimmune condition where the body's immune system mistakenly attacks the joint lining (synovium), causing inflammation, pain, and potential joint destruction. It typically affects the small joints of the hands and feet symmetrically, and can also affect larger joints and other organs.

Risk Factors and Causes

Understanding what contributes to arthritis helps guide prevention and management:

• Age – The risk of osteoarthritis increases with age as cartilage naturally loses its resilience and ability to repair
• Excess body weight – Every kilogram of excess body weight adds approximately 4 kg of force across the knee joint. Malaysia's rising obesity rate directly contributes to increasing OA prevalence
• Previous joint injury – A history of knee ligament tears, meniscus injuries, or fractures significantly increases the risk of developing arthritis in that joint
• Genetics – Both OA and RA have genetic components. A family history of arthritis increases your risk
• Gender – Women are more likely to develop both osteoarthritis (especially after menopause) and rheumatoid arthritis
• Occupation – Jobs requiring repetitive kneeling, squatting, or heavy lifting increase the risk of knee and hip OA

Symptoms Across Different Joints

Arthritis symptoms can vary depending on the type and the joints affected:

• Knee arthritis – Stiffness after sitting, pain when climbing stairs or squatting, grinding sensations, and gradual bowing of the legs
• Hip arthritis – Groin pain when walking, difficulty putting on shoes and socks, and reduced ability to cross the legs
• Hand arthritis – Bony swellings on finger joints, difficulty gripping, and weakness when opening jars or turning taps
• Spine arthritis – Stiffness and aching in the neck or lower back, particularly in the morning or after prolonged positions
• Rheumatoid arthritis – Morning stiffness lasting more than 30 minutes, symmetric joint swelling, fatigue, and periods of flare and remission

If you recognise these symptoms, it is important to seek professional assessment rather than trying to self-diagnose. Many conditions share similar symptoms, and an accurate diagnosis is crucial for effective treatment.

Evidence-Based Physiotherapy for Arthritis

International guidelines consistently recommend exercise and physiotherapy as first-line treatment for arthritis – before medication and far before surgery is considered.

Therapeutic Exercise

Exercise is the single most important treatment for arthritis, with benefits comparable to pain medications but without the side effects:

• Strengthening exercises – Building muscle around the affected joint provides natural shock absorption and support. For knee OA, quadriceps strengthening alone can reduce pain by 25-30%
• Aerobic exercise – Walking, swimming, cycling, and water aerobics improve cardiovascular fitness, reduce stiffness, and help manage body weight. Malaysia's year-round warm climate and numerous swimming facilities make aquatic exercise especially accessible
• Flexibility exercises – Gentle stretching and range of motion exercises maintain joint mobility and prevent further stiffness
• Balance training – Particularly important for knee and hip arthritis to reduce fall risk and improve confidence with daily activities

Manual Therapy

Hands-on treatment helps manage pain and maintain joint mobility. Gentle joint mobilisation, soft tissue techniques, and stretching can provide significant symptom relief, particularly during flare-ups.

Education and Self-Management

Understanding arthritis helps you to manage it effectively. Key messages include: exercise is safe and beneficial for arthritic joints (it does not cause further damage), pain during exercise does not necessarily mean harm, maintaining activity is critical for long-term joint health, and flare-ups are normal and manageable.

Managing Arthritis in Malaysian Daily Life

• Stay active within your comfort level – regular movement keeps joints lubricated and muscles strong. Walking in air-conditioned shopping malls is a popular and comfortable exercise option
• Manage your weight – even a 5% reduction in body weight can significantly reduce knee pain from arthritis
• Use joint protection strategies – carry bags with both hands, use jar openers, and sit in chairs with armrests to reduce joint stress
• Apply heat for stiffness (warm showers in the morning) and cold packs for acute swelling after activity
• Consider your footwear – supportive, cushioned shoes with good arch support protect the knees and hips during walking

When to Consider Surgery

Joint replacement surgery is appropriate when arthritis significantly impairs quality of life despite thorough conservative management. Malaysia has excellent orthopaedic facilities for knee and hip replacement.

However, surgery should be considered only after a genuine trial of physiotherapy and lifestyle modification. Many patients who are initially told they need surgery find that a focused exercise programme significantly improves their symptoms.

Keep Moving, Keep Living

Arthritis is a manageable condition. With the right physiotherapy guidance, exercise programme, and self-management strategies, most people with arthritis maintain active, independent lives.
