Have you heard of “runner’s knee”?


Chondromalacia patellae, also known as runner’s knee, is a chronic orthopedic condition, is very prevalent among young and middle-aged adults (20-50 years old).

You may think that a young person is in the pink of health and should not be suffering from knee pain common in the elderly. However, the cruel truth is that a lot of young people experience pain in their knee joints when climbing up the stairs or their legs may suddenly give way. Some even have difficulty squatting and their knee-caps feel uncomfortable on chilly, rainy days. More serious cases will see recurrent swelling (“water on the knee”), which is not easy to stamp out in the long-term. What is going on?

What is the “runner’s knee”? What is the cause?

To understand this condition, we need to first understand the patella, colloquially known as the knee-cap. In front of our knee, the round bone is our knee cap. The knee-cap is “encased” in four quadriceps muscles – rectus femoris, vastus lateralis, vastus intermedius, and vastus medialis. The knee-cap is essential as it acts as an anatomic pulley for the quadricep muscles during knee extension. ¼ of the cases of knee joint pain is caused by the knee-cap.

Why would knee-cap suddenly soften?

This is known as chondromalacia patellae. If you have eaten pork bones, you would know that bones have cartilage. Cartilage is smooth and shiny – it is the frictional surface of our joints. In the long run, wear and tear will cause the cartilage to deteriorate or become damaged. The severity of the degeneration also varies. At the early stage, the cartilage softens. Then, it thins out and falls off. There is hope at the early stage!
