What Is Osteoarthritis?

Osteoarthritis is a degenerative joint condition in which the cartilage cushioning the ends of your bones gradually breaks down. Cartilage acts as a shock absorber — smooth and slippery, it allows joints to move with minimal friction. When it wears away, bone starts rubbing on bone, causing pain, stiffness, and swelling.

OA can affect any joint, but it most commonly targets the knees, hips, hands, and spine.

Who Gets It?

OA becomes more common with age, but it’s not exclusively a condition of the elderly. Several factors increase the risk:

Age — The risk rises significantly after 45, and most people over 65 have some degree of OA. Body weight — Excess weight places more load through the joints, particularly the knees and hips. Previous joint injury — A torn ligament, fracture, or years of repetitive joint stress can accelerate cartilage breakdown much later in life. Genetics — OA can run in families, especially affecting the hands and knees. Gender — Women are more likely to develop OA, particularly after menopause.

Who Is at High Risk?

While anyone can develop OA, certain groups face higher risk. Understanding these factors can help you recognise early signs and take preventive action.

Older adults, particularly women post-menopause, are at significantly higher risk. Declining oestrogen levels after menopause are believed to accelerate cartilage breakdown, which is why OA increases sharply in women beyond 50. People living with obesity experience increased load through weight-bearing joints like the knees, hips, and lower back, which accelerates cartilage wear over time. Those with a history of joint injury or occupational stress — construction workers, athletes, labourers, and office workers performing repetitive motions — are at elevated risk. Even an injury sustained decades earlier can set the stage for OA later. Family history plays a notable role, especially for hand and knee OA, suggesting a genetic component to cartilage resilience. Finally, people with metabolic conditions like diabetes face accelerated joint degeneration, as high blood sugar can damage cartilage and reduce joint lubrication.

Common Symptoms

Symptoms tend to develop gradually and worsen over time. The most common include joint pain that worsens with activity and eases with rest, morning stiffness that typically resolves within 30 minutes of moving around, swelling around the affected joint, and a grating or crunching sensation — known as crepitus — when the joint moves. Over time, flexibility can reduce and range of motion may become limited.

How Is It Diagnosed?

There’s no single definitive test for OA. Diagnosis is usually based on a clinical assessment — a doctor or physiotherapist will review your symptoms, examine the joint, and consider your history. X-rays are commonly used to look for signs such as joint space narrowing and bone changes, though the severity of symptoms doesn’t always match what imaging shows.

It’s also important to rule out other forms of arthritis — rheumatoid arthritis, for example, has a different cause and requires a different treatment approach entirely.

Can Osteoarthritis Be Prevented?

While you can’t change your age, family history, or past injuries, several modifiable factors can significantly reduce your OA risk. Prevention is far easier and more effective than managing the condition once it develops.

Maintain a healthy weight. Each pound of excess weight places additional load through your knees and hips. Even a modest weight loss — as little as 5–10% of body weight — can meaningfully reduce joint stress and lower OA risk. Stay physically active. Regular low-impact exercise like walking, swimming, and cycling keeps cartilage nourished (movement pumps nutrients into joints), strengthens supporting muscles, and maintains flexibility. Aim for at least 150 minutes of moderate activity per week. Protect your joints. Use proper technique in sport, take breaks during repetitive work tasks, wear supportive footwear, and use protective equipment when needed. Small habits prevent years of cumulative damage. Eat an anti-inflammatory diet. Foods rich in omega-3 fatty acids, antioxidants, and vitamins — such as fatty fish, leafy greens, berries, and nuts — support cartilage health and reduce systemic inflammation. Avoid smoking. Smoking is linked to worse cartilage quality and accelerated joint degeneration. If you smoke, quitting provides benefits across your entire health profile. Manage other health conditions. Conditions like diabetes, high cholesterol, and hypertension all accelerate cartilage breakdown. Controlling blood sugar, blood pressure, and cholesterol protects your joints as much as it protects your heart.

Treatment and Management

Here’s the part that surprises many people: exercise is the single most effective treatment for osteoarthritis. Staying active — rather than resting to protect the joint — reduces pain, improves function, and slows progression. Physiotherapy plays a central role in guiding safe, targeted movement.

Exercise — Strengthening the muscles around an affected joint reduces the load placed on it. Low-impact activities like swimming, cycling, and walking are particularly beneficial. Weight management — Losing even a small amount of weight can meaningfully reduce pain in weight-bearing joints. Pain relief — Paracetamol and topical anti-inflammatories are commonly used for short-term symptom control. Assistive devices — Braces, orthotics, and walking aids can offload a joint and improve confidence with movement. Surgery — Joint replacement is an option in severe cases where other treatments haven’t helped, but it remains a last resort, not a first step.

Living Well With Osteoarthritis

An OA diagnosis doesn’t mean a life of limitation. Many people with OA remain highly active and manage their symptoms well. Keep moving — but pace yourself. Balance activity with adequate rest, avoid long periods of inactivity, and warm up before exercise. Stay engaged in activities you enjoy; the mental health benefits of staying active matter just as much as the physical ones.

Mindset matters too. Research consistently shows that people who understand their condition, take an active role in self-management, and keep moving do significantly better than those who adopt a passive approach.

A Final Word

If you’re experiencing joint pain, stiffness, or reduced mobility, it’s worth speaking to a healthcare professional — ideally early, before symptoms become more disruptive. A physiotherapist can build an exercise programme tailored to your specific joints, fitness level, and goals.

Osteoarthritis is a manageable condition. With the right approach, most people can stay active, reduce pain, and maintain a genuinely good quality of life.
