Knee Joint Structure

Your knee is an important joint in your body that helps you stand, walk, and move your legs. This joint is made up of three main bones:

Femoral Condyles (Lower part of the thigh bone): The rounded end of the thigh bone that meets the knee.

Tibial Plateau (Upper part of the lower leg bone): The flat top part of the lower leg bone that connects to the thigh bone.

Patella (Kneecap): The small bone at the front of your knee that helps your muscles.

At the ends of these bones, there's a smooth layer called Cartilage. This layer prevents the bones from rubbing against each other and makes movement easy. Strong bands called Ligaments hold the joint together and make it stable.

Problems the Knee Joint Faces

Over time or due to certain reasons, the knee joint can face several problems that cause pain and make it difficult to move. Some common problems include:

  • Osteoarthritis: This is the most common joint disease where the cartilage slowly wears away.
  • Rheumatoid Arthritis: This is an autoimmune disease where the joints become swollen and damaged.
  • Other Types of Arthritis: Such as Gout or arthritis caused by injuries.
  • Knee Injuries: Damage to the ligaments or cartilage due to sports or falls.
  • Bone Spurs: Extra growths of bone at the edges of the joints, which can cause pain.

Wear & Tear of the Knee Joint

Just like anything we use a lot, our knee joint can wear out over the years. This wear and tear can be increased by:

Age: As we get older, the cartilage naturally becomes thinner.

Excess Weight: Being overweight puts extra pressure on the knees, causing them to wear out faster.

Previous Knee Injuries: Old injuries can lead to wear and tear over time.

Repetitive Motion: Certain jobs or sports that put a lot of stress on the knees can increase wear and tear.

Genetics: Some people are more likely to have their joints wear out earlier due to their genes.
