Answer

Surgical therapy by excision of the mass is the mainstay of treatment for most symptomatic cysts that are not bursal in nature and that have not responded to nonsurgical treatment. [25, 26] (Note: Treatment should be directed at the cause of the enlarged cyst, such as adventitial bursal cysts caused by an osteochondroma or an enlarged Baker cyst that requires addressing intra-articular causes through arthroscopic surgical procedures.) Other cysts, such as meniscal cysts, extraneural cysts, and ganglion cysts, can respond to surgical excision.

In a study of meniscal tears and associated parameniscal cysts, partial meniscectomy alone, without meniscal cyst decompression, was found to provide excellent short-term and medium-term outcomes. Patients with medial cysts greater than 1.0 cm, with horizontal cleavage tears, or without simultaneous chondroplasty scored higher in the short-term and medium-term. [27]
