Sclerotherapy . There are several case series using sclerotherapy with dextrose to shrink the size of the cyst. This is level 4 evidence and requires more thorough investigation to demonstrate the utility [5].

Arthroscopy. Open excision is associated with high recurrence rates so surgical management revolves around an arthroscopic approach. In some cases, treatment is primarily directed toward intra-articular etiology such as meniscus or cartilage injuries. Indication for treating the cyst directly is usually failure of conservative therapy. Some surgeons will debridge the “one way valve” to allow open communication of the bakers cyst with the rest of the joint space. Alternatively, they may also attempt to close the communication between the cyst and the joint space. Cystectomy represents another option. Most of these treatment options are limited to case studies and there are no clear guidelines for surgical decision making [7].
