Meniscal Cyst

By

Updated April 29, 2014

Definition: A meniscal cyst is an outpouching of joint fluid caused by a tear within the meniscus. Meniscal cysts are most commonly seen near the lateral meniscus (outside of the knee) and are associated with a specific type of meniscal tear called a horizontal cleavage tear.

Meniscal cysts can be drained with a needle in the office, but they will often come back. The reason for the return of the meniscal cyst is that the tear that leads to the cyst must also be treated. The meniscal cysts are usually best treated with arthroscopic treatment of the meniscal tear. The meniscal cyst will usually decompress and less commonly returns.

Meniscal cysts are related to popliteal or Baker's cysts--however, these types of cysts are located in the back of the knee joint.
