Osteoarthritis: Causes, Symptoms, Diagnosis, and Management

reviewed by-medskology medical team

Introduction

Osteoarthritis (OA) is the most common form of arthritis, characterized by gradual degeneration of joint cartilage and underlying bone. It primarily affects weight-bearing joints such as the knees, hips, spine, and hands. Osteoarthritis is a chronic condition that can lead to pain, stiffness, and reduced mobility.

What Is Osteoarthritis?

Osteoarthritis is a degenerative joint disorder in which the protective cartilage that cushions the ends of bones wears down over time. As cartilage deteriorates, bones may rub against each other, causing pain, inflammation, and restricted movement.

Causes of Osteoarthritis

Osteoarthritis develops due to wear and tear of joint cartilage over time. Risk factors include aging, obesity, joint injury, repetitive stress, genetic predisposition, and poor joint alignment. These factors contribute to breakdown of cartilage and changes in bone structure.

Osteoarthritis develops due to a combination of factors:

Commonly Affected Joints

Symptoms of Osteoarthritis

Symptoms include joint pain that worsens with activity, stiffness (especially after rest), reduced range of motion, and swelling. Some patients may also experience a grinding sensation (crepitus) during joint movement.

Symptoms usually develop gradually and worsen over time.

Common Symptoms

Advanced Symptoms

Complications

If unmanaged, osteoarthritis can lead to:

Diagnosis of Osteoarthritis

Diagnosis is based on clinical evaluation and imaging studies such as X-rays, which show joint space narrowing, osteophyte formation, and bone changes. MRI may be used in selected cases for detailed assessment.

Clinical Evaluation

Imaging

Laboratory Tests

Blood tests are generally normal and used mainly to rule out other forms of arthritis.

Management of Osteoarthritis

Management focuses on symptom relief and improving joint function. This includes lifestyle modifications, weight reduction, physical therapy, and medications such as pain relievers or anti-inflammatory drugs. In advanced cases, joint injections or surgical procedures like joint replacement may be required.

There is no cure for osteoarthritis, but symptoms can be effectively managed.

1. Lifestyle Modification

2. Physical Therapy

3. Medications

⚠️ Medications should be used under medical supervision.

4. Supportive Measures

5. Intra-Articular Injections

6. Surgical Management

Considered in advanced disease:

Diet and Nutrition

Prevention of Osteoarthritis

Prognosis

Osteoarthritis is a slowly progressive condition. With early diagnosis, lifestyle changes, and appropriate management, many individuals can maintain good quality of life.

Conclusion

Osteoarthritis is a common degenerative joint disease that affects millions worldwide. While it cannot be cured, a combination of lifestyle modification, medical management, and physical therapy can significantly reduce symptoms and improve joint function.
