Chondromalcia : The cartilage under your kneecap is a natural shock absorber. Overuse, injury or other factors may lead to a condition known as chondromalacia patella — a general term indicating damage to the cartilage under your kneecap. A more accurate term for chondromalacia patella is patellofemoral pain syndrome.

Further evaluation: Your patella or knee cap is a common source of pain especially in a young women. In older people, pain in the anterior aspect of the knee often is related to osteoarthritis. At your age, clicking with or without patella pain could relate to inflammation as you were advised. I would also consider patellar malalignment and resultant early onset of cartilage disease. Meniscal tears also cause click.
