The primary disease that weakens joints is osteoarthritis.
Understanding Osteoarthritis
Osteoarthritis, the most prevalent form of arthritis, significantly impacts joint health. The core issue arises when the protective cartilage, which cushions the ends of the bones within a joint, deteriorates over time. This wear and tear can lead to a variety of problems, causing pain, stiffness, and reduced joint function.
How Osteoarthritis Weakens Joints
When cartilage erodes, the bones begin to rub against each other directly. This bone-on-bone contact causes:
- Pain: The friction and pressure lead to discomfort, which can vary from mild to severe.
- Stiffness: Joint mobility is reduced, especially after periods of inactivity.
- Reduced Function: The weakened joint makes everyday activities difficult and painful.
Common Areas Affected by Osteoarthritis
While osteoarthritis can affect any joint in the body, it is most commonly found in:
- Hands
- Knees
- Hips
- Spine
Reference Information
Based on the provided reference, "Osteoarthritis is the most common form of arthritis, affecting millions of people worldwide. It occurs when the protective cartilage that cushions the ends of the bones wears down over time. Although osteoarthritis can damage any joint, the disorder most commonly affects joints in your hands, knees, hips and spine."
Summary
Osteoarthritis is the primary disease that weakens joints by causing the protective cartilage to break down, leading to bone-on-bone friction, pain, and reduced mobility. It is most prevalent in the hands, knees, hips, and spine.
