Introduction: A ganglion is a cystic, tumor-like lesion filled with gelatinous fluid that contains hyaluronic acid and other mucopolysaccharides and is encompassed by a dense network of collagen fibers and fibrocytes. The operation is intended to restore knee stability and improve the patient's quality of life. Historically, 75–90% of ACL surgeries result in patients being able to resume their previous level of athletic activity. Significant clinical symptoms are brought on by ACL ganglion cysts. Large ganglia may prevent full extension in these patients, who may also complain of discomfort and stiffness. Decompression of the ganglion at arthroscopy or under the direction of a CT scan is recommended for such patients and offers immediate relief
