Ever wonder what the white and shiny covering over the ends of bone was for? Known as articular cartilage, it serves as a good bearing surface of the joint, the smooth yet tough exterior of the cartilage are its defining characteristics. However, overtime degeneration of the cartilage may occur that in turn may lead to pain, osteoarthritis, and even disability of the joint.

How Do Articular Cartilage Injuries Occur?

Chondrocytes are cells that multiply or divide very slowly and are producers of articular cartilage. It’s due to the

slowness of the cells growth that result in slow repair rate of injuries to the articular cartilage, which in turn leads to continued joint deterioration and degeneration.

Compared to most other injuries, damage done to the articular cartilage can be focal, which means that the area is both localized and contained. This is the main reason why such damage often leads to joint osteoarthritis, which is a general term that is used to describe wear and tear of the articular cartilage. A much more severe stage of the condition is known as bone-on-bone arthritis, where the condition is usually at its final stages.

It’s when all the articular cartilage has worn off the bone, which leads to full exposure of the bone. This can lead to pain, swelling, joint disability and degeneration due to nerve endings being present in the underlying bone.

What Are The Causes Of Cartilage Injuries?

Cartilage can be damaged and injured due to a number of reason and causes but the important thing to remember is, most cartilage injuries are often traumatic in nature. Some common causes of articular cartilage injuries are;

  • Ligament Tear
  • Joint Dislocation
  • A Hard Fall/Impact
  • Meniscus Tear
  • An Infection
  • Inflammation

How To Effectively Recognize and Diagnose Joint Swelling?

If you notice joint swelling in an area persisting for more than one day following an injury, this is reason enough to be concerned. Have the joint evaluated by an orthopedic surgeon which will help in ruling out cartilage injury from a fracture, ligament or meniscus injury.knee cartilage defect

Normally, plain radiographs, or X-rays are used for making the diagnosis of fractures, while an MRI scan will be needed to determine meniscus or ligament injuries. In the case of a cartilage injury, you will be subjected to an MRI scan as well, due to it being considered the best diagnostic tool.

In addition to this, the orthopedic surgeon will be able to tell you of the type of joint injury sustained by examining the onset of joint swelling as explained below.

Immediate, i.e. less Than 1 Hour: Fracture, posterior cruciate ligament Tear, or ACL, Joint Dislocation

Sub-acute, i.e. At Least 2-6 Hours: Cartilage Injury, Meniscus Tear

Chronic: Unstable Cartilage, Infection, and Osteoarthritis
