Osteoarthritis Explained

Osteoarthritis Explained

What is Osteoarthritis?

Osteoarthritis (OA) is a degenerative joint disease characterized by the breakdown of cartilage, the protective tissue at the ends of bones. This causes pain, stiffness, swelling, and reduced mobility in the affected joints. Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide, particularly in weight-bearing joints like the knees, hips, and spine.

Classifying Osteoarthritis

Osteoarthritis is classified as a chronic degenerative condition affecting the joints. It is not an autoimmune or inflammatory disease like rheumatoid arthritis but primarily results from wear and tear on the joints over time.

Types of Osteoarthritis

1. Primary Osteoarthritis: This is the most common type and develops with age as a result of the natural wear and tear on the joints. It typically affects the hands, knees, hips, and spine.
2. Secondary Osteoarthritis: This type results from an underlying condition or injury, such as trauma, obesity, or other joint disorders. It can affect people at a younger age due to these risk factors.

Osteoarthritis Health Signs and Symptoms

Common signs and symptoms of osteoarthritis include:

• Joint Pain: Pain that worsens with activity and improves with rest.
• Stiffness: Especially noticeable after periods of inactivity, like waking up in the morning.
• Swelling: Mild swelling around the affected joint due to inflammation.
• Loss of Flexibility: Difficulty moving the joint through its full range of motion.
• Grating Sensation: A crackling or grinding feeling when moving the joint.
• Bone Spurs: Hard lumps that may form around the joint, causing additional discomfort.

Osteoarthritis Causes

Osteoarthritis is primarily caused by the gradual wear and tear of joint cartilage. Contributing factors include:

• Aging: The risk of osteoarthritis increases as you age.
• Joint Injury: Injuries from sports, accidents, or overuse can increase the risk of developing OA.
• Obesity: Excess body weight places additional stress on weight-bearing joints like the hips and knees.
• Genetics: Family history of osteoarthritis can increase the likelihood of developing the condition.
• Joint Abnormalities: Congenital joint disorders or improperly formed joints can lead to earlier onset of OA.

Osteoarthritis Stages

1. Early Stage: Minor wear and tear of the cartilage with occasional discomfort or stiffness, often after physical activity.
2. Intermediate Stage: Noticeable loss of cartilage, pain during regular activities, and more frequent stiffness and swelling.
3. Advanced Stage: Significant cartilage loss, severe joint pain, decreased mobility, and bone-on-bone contact, leading to disability.

How to Prevent Osteoarthritis?

While osteoarthritis is not entirely preventable, you can reduce the risk by:

• Maintaining a Healthy Weight: Reducing stress on joints, especially the knees and hips.
• Regular Physical Activity: Low-impact exercises like swimming, walking, and cycling help keep joints flexible and muscles strong.
• Avoiding Joint Injury: Protect joints from trauma by using proper form during physical activities and wearing protective gear.
• Strengthening Muscles: Strong muscles around joints, particularly the knees and hips, provide better support.
• Balanced Diet: A diet rich in antioxidants and anti-inflammatory foods, like fruits, vegetables, and omega-3 fatty acids, can support joint health.

Osteoarthritis Diagnosis

To diagnose osteoarthritis, doctors will:

• Review Symptoms: Pain, stiffness, and mobility issues.
• Physical Examination: Check for swelling, tenderness, limited range of motion, and bone spurs.
• Imaging Tests: X-rays to reveal cartilage loss, bone spurs, and joint space narrowing. MRI scans may also be used for a detailed view of soft tissues and cartilage.
• Blood Tests: To rule out other forms of arthritis, like rheumatoid arthritis.
• Joint Fluid Analysis: Fluid may be withdrawn from the joint to check for inflammation or other conditions like gout or infection.

How to Test for Osteoarthritis

• X-Rays: Primary diagnostic tool to detect cartilage loss and bone changes.
• MRI: Used for a more detailed view of joint damage when x-rays are inconclusive.
• Joint Fluid Analysis: Tests for inflammation or infection in the joint fluid.
