Arthritis is a broad term for a group of conditions that cause pain and swelling in the joints. It is a leading cause of disability among older adults, often impacting mobility and quality of life.

Types of Arthritis

While there are many forms of arthritis, the following are the most common:

  • Osteoarthritis (OA): The most frequent type, often called “wear and tear” arthritis. It occurs when the protective cartilage that cushions the ends of one’s bones wears down over time.
  • Rheumatoid Arthritis (RA): An autoimmune and inflammatory disease where one’s immune system attacks healthy cells in one’s body by mistake, causing painful swelling in the affected joints.
  • Psoriatic Arthritis: Affects some people who have psoriasis—a condition that features red patches of skin topped with silvery scales.
  • Gout: High levels of uric acid in the blood lead to the formation of crystals that accumulate in the joints. It can be triggered by impaired kidney function—where the body fails to excrete uric acid efficiently—or by a diet high in meat and alcohol. Gout is typically characterized by sudden, intense pain and swelling, most commonly affecting the big toe.
  • Ankylosing Spondylitis: An inflammatory disease that, over time, can cause some of the small bones in one’s spine to fuse.

Who Gets Arthritis?

The prevalence of arthritis increases sharply after age 65, with approximately 54% of adults aged 75 and older having been diagnosed with the condition. Key risk factors include:

  • Obesity: Excess weight puts added stress on joints, particularly the knees and hips.
  • Previous Injuries: Joints damaged by past injuries are more likely to develop arthritis later.
  • Genetics: Certain genes are linked to a higher risk of RA and ankylosing spondylitis.
  • Repetitive Stress: Jobs or sports that require repetitive joint bending can increase the risk of OA.

While the risk of stroke increases with age, younger populations face a rise in arthritis conditions. Approximately one in five U.S. adults—roughly 21% or 53 million people—live with arthritis. Notably, over half of those affected (51.7%) are within the working-age population (18 to 64 years old). Arthritis is more prevalent in women than in men, with both osteoarthritis and rheumatoid arthritis being significantly more common among women.

Causes of Arthritis

Causes depend on the type. Osteoarthritis results from the physical breakdown of cartilage due to age or injury. Rheumatoid arthritis is caused by a dysfunctional immune response. Other forms, like Gout, are metabolic, resulting from an imbalance of chemicals in the blood.

Signs & Symptoms of Arthritis

  • Persistent joint pain and stiffness, especially in the morning.
  • Visible swelling, redness, or warmth around the joints.
  • A “grating” sensation or sound during movement.
  • Reduced range of motion that makes daily tasks difficult.

Stages of Arthritis

  1. Early Stage: Marked by mild inflammation and the onset of cartilage wear. Patients typically experience morning stiffness and occasional aches that subside with rest, having little impact on daily routines.
  2. Intermediate Stage: As tissue damage progresses, pain and swelling become more frequent and persistent. Everyday tasks like climbing stairs become difficult, and discomfort may begin to interfere with sleep and energy levels.
  3. Late Stage: Severe cartilage loss leads to joint deformity and constant chronic pain. With range of motion significantly restricted, daily independence declines, often requiring assistive devices or joint replacement surgery.

Diagnosis of Arthritis

  • Physical Exams: Checking joints for fluid, redness, and range of motion.
  • Imaging: X-rays to see bone changes and cartilage loss; MRI for detailed views of soft tissue.
  • Laboratory Tests: Blood tests to look for inflammation markers (like C-reactive protein) or specific antibodies (like Rheumatoid Factor).
  • Surgery: Joint replacement surgery (Arthroplasty) for severely damaged hips or knees.

Treatment of Arthritis

  • Medications: Including nonsteroidal anti-inflammatory drugs (NSAIDs) or disease-modifying antirheumatic drugs (DMARDs) for RA.
  • Physical Therapy: Exercises to strengthen muscles around the joints and increase flexibility.
  • Weight Management: Reducing body weight significantly lowers pressure on weight-bearing joints.
  • Surgery: Joint replacement surgery (arthroplasty) for severely damaged hips or knees.

Prevention of Arthritis

  • Maintaining a Healthy Weight: Engaging in regular physical activity—such as 150 minutes of moderate-intensity exercise per week (e.g., swimming, cycling, or walking)—is the most effective way to reduce joint pain, improve function, and slow the progression of the disease.
  • Joint Protection: Using proper form when lifting and wearing protective gear during sports.
  • Low-Impact Exercise: Activities like swimming, cycling, or walking keep joints flexible without excessive strain.

Living with Arthritis

Living with arthritis involves pacing activities to avoid overexertion. The use of heat therapy (to relax muscles) and cold therapy (to reduce inflammation), along with assistive devices like jar openers or canes, can help reduce joint strain and preserve independence.
