A surgical algorithm for treatment of cystic degeneration of the Meniscus.

Abstract

Cystic degeneration of the meniscus is not uncommon. Recent reports suggest that most (or all) meniscal cysts are associated with a meniscal tear, and that the treatment of choice is arthroscopic partial meniscectomy with cyst decompression. This report describes a case of a symptomatic lateral meniscal cyst that was suspected clinically and confirmed by magnetic resonance imaging, but was not associated with a meniscal tear at arthroscopy. Open cyst extirpation and peripheral meniscal repair were performed to maximize preservation of meniscal tissue. A clinical algorithm is presented for management of meniscal cysts.
