Intrameniscal Cyst—Arthroscopic Open- and Closed-Door Repair Technique

Meniscal cyst is rare and usually is associated with degenerative horizontal meniscus tears. These cysts are parameniscal in nature, as synovial fluid collects due to a check-valve mechanism. Most often, they are located on at the posteromedial aspect of the knee. Various repair techniques had been established in the literature to decompress and repair them. We describe an isolated intrameniscal cyst with an intact meniscus managed by arthroscopic open- and closed-door repair technique.
