What causes chondromalacia patellae?
Chondromalacia patellae is often caused by a kneecap that is out of line so it doesn't slide smoothly over your knee joint. Running or other activities that involve a lot of knee bending make the bottom of the kneecap scrape on the knee bones. This can damage the cartilage on the bottom of the kneecap.
