Surgical treatment of chondromalacia patellae is usually a good improvement for most patients who suffer from pain due to chondromalacia patellae problems, but whether or not it is appropriate to use this procedure still needs to be performed in accordance with the doctor’s instructions. 1. Chondromalacia patella is usually caused by a chronic injury in which the patellar cartilage becomes swollen and broken, and the corresponding femoral condylar cartilage undergoes the same changes, resulting in osteoarthritis of the patellofemoral joint. Chondromalacia is the most common cause of anterior knee pain, often characterized by clicking and knee swelling. 2. Many patients opt for surgical correction of chondromalacia patella, which is relatively easy to correct through arthroscopic surgery. The vast majority of patients are satisfied with the results of this procedure. If symptoms do not improve after surgery, patellar replacement should be considered. The choice of surgery for chondromalacia patella is recommended to visit a hospital orthopedic department for a comprehensive evaluation and follow the doctor’s instructions.
