In daily life, many people often experience pain around the patella (kneecap), especially when walking up and down stairs or squatting, and some people even experience knee joint “deconditioning”. In the face of this situation, many people will wonder if they have rheumatoid arthritis, knee spurs, etc.. If you have these symptoms, you probably have chondromalacia patellae. Patellar chondromalacia is one of the common causes of knee pain and is a strain disease of the knee joint, so it is also known as patellar strain injury, with more incidences in young people. It is mostly caused by trauma, torsion, excessive wear and tear or degenerative changes to the patella. It is mostly seen in athletes, dancers and those who are engaged in long-term semi-squatting work and repeated flexion and extension of the knee joint. The clinical manifestations are knee discomfort, weakness and friction-like pain. The pain is characterized by pain in the semi-squatting position, aggravated when walking up and down stairs, pain at the beginning of the movement, and pain relieved by a few moments of activity. In some cases, the phenomenon of “limp leg” and “pseudoglutination” may occur, and in advanced stages of the disease, quadriceps atrophy and inability to stand on one leg may occur. The examination shows obvious pressure pain around the patella and below the patella, as well as atrophy of the quadriceps muscle and positive hyperextension test, but generally no activity disorder.
