Popliteal cyst (Baker’s cyst) was first described by Adams in 1840, popularized by Baker in 1877, and was theorized as an enlarged gastrocnemiussemimembranosus bursa that communicated with the knee and trapped synovial fluid.1 Numerous bursa are located in the popliteal space between the knee ligaments, hamstring tendons, gastrocnemius muscle, and collateral ligaments. The two proposed etiologi...

A seven-year-old Labrador Retriever dog was presented with the complaint of chronic left hindlimb lameness. A diagnosis of partial rupture of the left cranial cruciate ligament with concurrent cranio-medial synovial cyst formation was made. This cystic structure was assumed to be communicating with the stifle joint. There was no evidence of a meniscal tear, but superficial fibrillation of the a...

AIM To identify degenerative knee abnormalities using MRI and radiography 6 years after knee trauma, their relation with persistent knee symptoms and baseline prognostic factors. METHODS Adults (18-65 years) with incident traumatic knee symptoms visiting their general practitioner were followed up for 6 years and underwent baseline MRI and 6-year follow-up MRI and radiography. Logistic regres...

and medial and lateral sural nerves. A Baker’s cyst in this area can cause lower leg pain, paresthesia, and muscle weakness by the compression of the tibial nerve [5]. The authors were careful not to damage the lateral and medial sural nerves while dissecting the lateral head of the gastrocnemius muscle. Surgeons should have a precise plan to explore and dissect the popliteal fossa and to not d...

BACKGROUND There are several reports of symptomatic ganglion cysts near the anterior cruciate ligament (ACL), posterior cruciate ligament (PCL), and lateral and medial meniscus, but symptomatic ganglia arising from the anterior horn of the medial meniscus to the ACL have not been reported. Here we report the arthroscopic resection of a ganglion cyst arising from the anterior horn of the medial ...

Im ag es A cystic mass arising in the popliteal fossa can be either a meniscal cyst, a synovial cyst (Baker’s cyst), or a ganglionic cyst [1]. Soft-tissue popliteal masses can be evaluated using physical examinations and imaging studies, such as computed tomography (CT) or magnetic resonance imaging (MRI). Thereafter, pathologic studies can be used for making a final confirmation of the diagnos...

Ganglion cysts are lesions resulting from the myxoid degeneration of the connective tissue associated with joint capsules and tendon sheaths. Most common around the wrist joint, ganglion cysts may be found elsewhere in the body, including in and around the knee joint. Uncommonly, ganglion cysts can present intramuscularly. Previous reports document the existence of intramuscular ganglia, often ...
