Suprapatellar bursa effusion does not always heal on its own. The exact recovery time is related to the severity of the condition, the amount of fluid, etc. Usually it can be recovered in 1-4 weeks. The suprapatellar bursa can play a role in reducing shock and friction. When the suprapatellar bursa is irritated, it causes suprapatellar bursitis, with obvious edema and fluid accumulation. It is often manifested as less fluid accumulation and more fluid accumulation. 1. Less fluid accumulation: symptoms are not obvious, there may be soreness and discomfort, no special treatment is needed, and it will recover by itself after 1~2 weeks of rest. 2. More fluid accumulation: need to be treated with syringe pumping, reduce activities during the treatment period and pay attention to keep the joint warm. If the effusion is repeated, surgical resection is needed, and if the recovery is slow, it may take about 3-4 weeks to recover. In addition, it is necessary to pay attention to local warmth, avoid cold and avoid strenuous exercise. If any discomfort occurs, it is recommended to consult a doctor in time to avoid aggravation of the condition.
