The specific cost of surgical treatment for knee cysts depends on the localization of the cyst itself. If the cyst is in the popliteal fossa, the cost of the entire surgery is not particularly high and can be solved by a simple excision, which can be done for about $8,000-10,000. If a distal femoral or proximal tibial cyst is present, in addition to scraping out the cystic lesion, surgical treatment with bone grafting is required, which is relatively more expensive, around 15,000-20,000 yuan. In addition, the cost of surgery for meniscus cysts or cruciate ligament cysts can also be very different. A cruciate ligament cyst will require a ligament reconstruction, which may cost $30,000-$50,000. A simple meniscal cyst excision is all that is required for a meniscal cyst, which also costs about $20,000. If there are certain complications during the whole process and the hospital stay is long, the cost may increase a lot on top of that.
