The treatment of synovial cysts is based on the size of the cyst and whether there are clinical symptoms, to make a comprehensive choice, as follows: 1. Conservative treatment: If the synovial cyst is relatively small and there are no clinical symptoms, such as pain, affecting joint movement, then it can be treated conservatively and only requires regular review. 2. Surgical treatment: If the synovial cyst is relatively large and there is significant pain, swelling, or affecting joint function, then it can be treated surgically, including removal of the cyst. If the synovial cyst is large and causes significant pain, swelling, or affects the function of the joint, it can be treated surgically, including excision of the cyst. If the cyst is present in certain areas, such as the popliteal fossa of the knee, it can be treated by minimally invasive arthroscopic surgery, which is a more advanced treatment method for synovial cysts because of its low trauma and quick recovery. Therefore, the treatment of synovial cysts is a comprehensive choice based on the size of the cyst and the presence or absence of clinical symptoms.
