Arthroscopic internal drainage of popliteal cysts using the figure-of four position: a retrospective case series

Arthroscopic internal drainage of popliteal cysts using the figure-of-four position is a technically feasible and safe procedure that resulted in significant clinical improvement and a low rate of asymptomatic recurrence at short-to-mid-term follow-up. The figure-of-four position appears to be a useful technical adjunct for improving access and working space in the posteromedial compartment, and warrants further investigation.
