Osteoarthritis is the most common form of arthritis and a leading cause of joint pain and disability worldwide. It develops when the protective cartilage that cushions the ends of bones gradually wears away, causing the bones to rub against each other.
Although osteoarthritis is more common in older adults, it is not an inevitable part of ageing. Early diagnosis and proper management can help reduce pain, improve movement, and maintain quality of life.
What Is Osteoarthritis?
Osteoarthritis is a degenerative joint disease that affects the cartilage inside joints.
Cartilage acts as a smooth cushion that allows bones to move easily. As it breaks down over time, the joints become painful, stiff, and less flexible.
The condition most commonly affects the:
- Knees.
- Hips.
- Hands.
- Fingers.
- Spine.
What Causes Osteoarthritis?
Several factors contribute to osteoarthritis, including:
- Ageing.
- Previous joint injuries.
- Obesity, which places extra pressure on weight-bearing joints.
- Repetitive movements from certain jobs or sports.
- Family history.
- Weak muscles around the joints.
Often, more than one factor is involved.
Common Symptoms
Symptoms usually develop gradually and may worsen over time.
Common signs include:
- Joint pain during or after activity.
- Stiffness, especially after waking up or sitting for long periods.
- Swelling around the affected joint.
- Reduced flexibility.
- A grinding, clicking, or cracking sensation when moving the joint.
- Bone spurs that may form around damaged joints.
Symptoms may come and go, especially in the early stages.
Who Is Most at Risk?
People at higher risk include:
- Adults over 50 years of age.
- Women, particularly after menopause.
- People who are overweight or obese.
- Individuals with previous joint injuries.
- Those with occupations involving repetitive joint movements.
- People with a family history of osteoarthritis.
How Is Osteoarthritis Diagnosed?
A healthcare provider may recommend:
- A physical examination.
- A review of symptoms and medical history.
- X-rays to assess joint damage.
- MRI in selected cases.
- Blood tests or joint fluid analysis to rule out other forms of arthritis.
Treatment Options
There is no cure for osteoarthritis, but treatment can help control symptoms.
Lifestyle Changes
Health experts recommend:
- Maintaining a healthy weight.
- Exercising regularly.
- Strengthening the muscles around affected joints.
- Staying physically active while avoiding activities that worsen pain.
Medications
Depending on the severity, treatment may include:
- Pain relievers.
- Anti-inflammatory medications.
- Topical creams or gels.
Medication should be used under the guidance of a healthcare professional.
Physical Therapy
A physiotherapist can recommend exercises to improve joint flexibility, muscle strength, and balance.
Surgery
In severe cases where pain and disability are significant, joint replacement surgery may be recommended.
Can Osteoarthritis Be Prevented?
Although it cannot always be prevented, you can reduce your risk by:
- Maintaining a healthy weight.
- Exercising regularly.
- Avoiding repetitive joint injuries.
- Using proper lifting techniques.
- Treating joint injuries promptly.
When Should You See a Doctor?
Seek medical advice if you experience:
- Persistent joint pain.
- Swollen joints.
- Stiffness lasting more than a few weeks.
- Difficulty performing everyday activities.
- Joint pain that interferes with sleep or mobility.
Early treatment can help slow progression and improve quality of life.
The Bottom Line
Osteoarthritis is a common condition caused by the gradual breakdown of joint cartilage. It commonly affects the knees, hips, hands, and spine, leading to pain, stiffness, and reduced movement. While there is no cure, healthy lifestyle habits, appropriate treatment, and early medical care can help manage symptoms and maintain an active lifestyle.
