Lateral Meniscal cysts are more common than the medial meniscus cysts, almost 10 times more common [1]. Trauma is the main etiology for meniscal cysts. 20 years old female came with complaints of pain and swelling the inner aspect of left knee, had a previous history of trauma 2 years back. On examination swelling was 1x2 cm on the medial aspect of left knee, which was firm in consistency. MRI diagnosed a tear in the posterior horn of the medial meniscus with a para meniscal cyst adjacent to the medial meniscus. Arthroscopically through posterior trans-septal approach, medial para meniscal cyst was surgically resected. If a meniscal cyst is arising from the posterior horn of the medial meniscus, arthroscopic posterior trans-septal decompression and resection is a suitable surgery.
