Articular cartilage cushions the femur (thighbone) and tibia (shinbone) where they meet in the knee, allowing them to move freely and easily. Chondromalacia patella is a softening or wearing away of the articular cartilage on the undersurface of the patella (kneecap).

Chondromalacia patella is caused by repetitive motion and misalignment of the kneecap.

This can occur due to:

  • Birth defect in knee alignment
  • Weak quadriceps
  • Muscle strength imbalance between the inside and outside of the thigh
  • Direct trauma
