Yesterday I let my med student friend do a practice knee exam on me he said I have chondromalacia.Chondromalacia (KON-dro-mah-LAY-she-ah), also called chondromalacia patellae, refers to softening of the articular cartilage of the kneecap. This disorder occurs most often in young adults and can be caused by injury, overuse, misalignment of the patella, or muscle weakness. Instead of gliding smoothly across the lower end of the thigh bone, the knee cap rubs against it, thereby roughening the cartilage underneath the knee cap. The damage may range from a slightly abnormal surface of the cartilage to a surface that has been worn away to the bone. Chondromalacia related to injury occurs when a blow to the knee cap tears off either a small piece of cartilage or a large fragment containing a piece of bone (osteochondral fracture). An article I read about it said it happens most to otherwise healthy young adults and is seen most commonly in runners, cyclist and skiiers, three sports I particiapte in every week which is probably why I have it. I don't feel any pain when I run or walk so I don't think I have it that bad, I wouldn't even know I have it if I hadn't let my friend practice knee exams on me. Will this prevent me from joing the army or TA?
