Chondromalacia patellae is a term used to describe the damage or softening of the cartilage on the underside of the kneecap. It is similar to patellofemoral pain syndrome (runner's knee) in which the pain is felt under and around the kneecap. This condition is common among young athletics but may also occur in older adults who have arthritis of the knee.
Injury to the anterior cruciate ligament is a devastating injury for athletes of all ages. Treatment usually involves surgery. If you undergo surgical reconstruction, you may have to choose between using your own tissue or using a donor graft.
