Arthroscopic Resection for Extra-articular Ganglion Cysts of Gastrocnemius Near Vessels

Extra-articular ganglion cysts arising from the gastrocnemius tendon near popliteal vessels can cause pain and claudication. Open resection of this kind of cyst has been described frequently because the vessels can be well protected with a retractor. However, it’s a challenge to remove cysts that are near vessels under arthroscopy, because a retractor cannot be used in arthroscopic surgery. This article will report a method of arthroscopic resection for extra-articular ganglion cysts near popliteal vessels.
