Chondromalacia Patella

Why you should fear knees that go creak in the night. It could be a sign of chondromalacia patella. 

What is chondromalacia patella?

In order for your knee cap to work normal it must move up and down in a groove in the thigh bone. This motion happens over and over as you bend and straighten your knee throughout your daily activities. What occurs with chondromalacia patella is the cartilage (cushioning) on the back of the knee cap starts to soften and wear down. Now the thigh bone and knee cap rub together and cause friction. This motion is an abnormal movement in the joint and leads to pain. Imagine if your car tire started to rub on your wheel well and this gives you an idea on what is going on in your knee.

 What causes Chondromalacia Patella?

Anything that may change how the knee cap should move in the normal groove of the thigh bone causes this to happen. This function is called Patella-femoral tracking. Below are listed the causes of chondromalacia patella.

  • Overweight
  • Prior knee injury to include fracture and dislocation.
  • Female secondary to hip angle
  • Flat footed biomechanics
  • Runners, bicyclists’, soccer players and individuals that exercise often.
  • Unusually shaped undersurface of kneecap
  • Weak Thigh muscles
  • Workers that climb and kneel frequently.

These factors put undo stress on the kneecap and can be a causative factor to Chondromalacia patella.


What are the signs of Chondromalacia Patella?

-Initial dull, aching pain in front or behind the knee cap.

– Pain that increases with running, jumping, climbing or going down steps.

– Sitting for longer periods with knees bent that cause pain.

– Crunching sounds with movements of the knee.


What happens if Chondromalacia Patella is left untreated?

-Loss of strength and muscle wasting of thigh muscle.

-Localized swelling around the knee cap.
