Two-Posteromedial Portal Arthroscopic Popliteal Cyst Excision.

The popliteal cyst is a common condition that causes disturbing symptoms. Several arthroscopic techniques are combined to treat the enlargement of communication and decompose the cyst wall, aiming to reduce recurrence. We propose a technique that involves resecting the posteromedial valve mechanism and excising the cyst wall through a 2-posteromedial portal approach. This technique is particularly helpful for visualization and facilitates complete resection of the cyst wall and capsular fold, even in large cysts, with low complication rates.
