Where does the cyst come from?
A meniscal cyst is a fluid-filled sac adjacent to the meniscus, often connected to a tear. It may form a small, painful mass on the side of the knee or be discovered without symptoms.
Confirming the diagnosis
The examination and MRI look for a cyst and any associated meniscal lesion. A mass in the knee should not automatically be considered a meniscal cyst. A popliteal cyst, located behind the knee, is a different entity.
Treating According to the Discomfort
Monitoring may be sufficient if the cyst is not causing problems. In case of persistent symptoms, treatment addresses the cyst and its meniscal communication: decompression or excision, with repair or limited treatment of the lesion depending on its nature.
The risk of recurrence
Recurrence remains possible. The postoperative course depends on any associated meniscal procedure; suturing may require specific precautions.
Your questions.
Should the entire meniscus be removed?+
No. The strategy aims to preserve as much functional meniscal tissue as possible.
