Several recent studies have reported successful treatment with partial lateral meniscectomy followed by cyst decompression. This procedure is done by placing arthroscopic instruments and/or shaver blades into the cyst from between the leaves of the horizontal meniscal tear. Meniscal cysts are highly associated with horizontal tears of the lateral meniscus. These tears communicate with the cyst and, much like a ganglia, allow joint fluid to accumulate and thicken in the cyst. Needle aspiration of the cyst from the outside in also can help with cyst decompression.
