In a promising breakthrough, scientists at Stanford University recently identified a key protein called 15-PGDH linked to cartilage loss during aging, offering hope for new treatments for osteoarthritis.

About Osteoarthritis

  • Arthritis is a general term that means inflammation of the joints.
  • Osteoarthritis (OA), commonly known as wear-and-tear arthritis, is the most common type of arthritis.
  • What Causes OA?
    • It is associated with a breakdown of cartilage in joints.
    • Cartilage is a firm, rubbery material that covers the ends of bones in normal joints. 
    • Its main function is to reduce friction in the joints and serve as a "shock absorber.
    • The shock-absorbing quality of normal cartilage comes from its ability to change shape when compressed (flattened or pressed together).
    • Osteoarthritis causes the cartilage in a joint to become stiff and lose its elasticity, making it more susceptible to damage. 
    • Over time, the cartilage may wear away in some areas, greatly decreasing its ability to act as a shock absorber. 
    • As the cartilage deteriorates, tendons and ligaments stretch, causing pain. 
    • If the condition worsens, the bones could rub against each other.
  • It commonly occurs in the weight-bearing joints of the hips, knees, and spine. 
  • It also affects the fingers, thumbs, neck, and large toe.
  • It usually does not affect other joints unless previous injury, excessive stress, or an underlying disorder of cartilage is involved.
  • It is more likely to develop as people age. But it can affect much younger people, too, especially those who have had a prior joint injury.
  • Symptoms: Symptoms of osteoarthritis most often develop gradually and include:
    • Joint aching and soreness, especially with movement
    • Pain after overuse or after long periods of inactivity
    • Stiffness after periods of rest
    • Bony enlargements in the middle and end joints of the fingers (which may or may not be painful)
    • Joint swelling
  • Treatment: 
    • Although there is no cure for osteoarthritis, there are many treatment options available to help manage pain and keep people active.
    • As a last resort, a damaged joint may be surgically fused or replaced with one made of a combination of metal, plastic, and/or ceramic.
