Review of Parameniscal Cysts Parameniscal or meniscal cysts are believed to result from the extrusion of synovial fluid through a tear in the meniscus. While these cysts are often asymptomatic and discovered incidentally during imaging, they can occasionally become symptomatic. Treatment options include non-surgical aspiration or surgical intervention involving cyst decompression and repair of the meniscus.

When symptoms are present, they commonly include activity-related knee pain, swelling, locking, popping, and a sense of instability.

The mass is most prominent along the joint line with the knee flexed at 20-30 degrees and is firmly fixed to the underlying tissues, lacking mobility in the subcutaneous layer Demonstration of a positive Pisani's test. The lateral meniscus is visible in partial knee flexion (a), disappears with full flexion (b) and appears with external rotation of the tibia (c).
