Chondromalacia patellae is caused by degeneration of the cartilage that forms the posterior capsule of the kneecap, and is very common in people who play sport, especially those involving considerable mechanical stresses on the knee, such as cycling, rugby, football, etc. In cases where the structure of the knee has not yet been completely damaged, it is known as femoral patella syndrome, and the symptoms are completely reversible. Some factors such as synovitis, misalignment of the joint, trauma, obesity, among others, can predispose to chondromalacia patellae.
Symptoms vary depending on the degree of evolution, and can include oedema with softening or fibrillation of the cartilage. In severe cases, fibrillation or fissuring of the deepest layers, even ulceration, can occur.
With ligament rehabilitation as a starting point in cases in which the cause is postural, the main objective should be realignment and stabilisation of the knee axis by means of a knee orthosis featuring stabilising elements that enable the patella to be centred and stabilised.
