In most cases, prepatellar bursitis does not resolve spontaneously. This is due to the presence of internal bursal closure and repeated localized irritation. The specific reasons are as follows.
1. Internal bursa closure: when the patient has an attack of the disease, aseptic inflammation will appear inside the bursa, which will lead to an increase in the internal fluid. As the bursa is surrounded by dense fibrous connective tissue, it is better sealed. Therefore, the internal inflammatory mediators and the accumulation of fluid for a long time, and then not easy to recover.
2. Repeated stimulation: After the onset of the disease, as long as the patient flexes the knee joint or uses the lower limbs to exert force, it will squeeze the affected bursa, which will lead to repeated attacks of inflammation here.
In view of the above characteristics of this kind of disease, so patients must go to the orthopedic clinic as soon as possible after the onset of the disease, and do not hope that the disease can be cured by itself.
