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

ABSTRACT:

Purpose

This study aimed to evaluate the efficacy and safety of arthroscopic internal drainage for popliteal cysts using the figure-of-four position.

Methods

Between January 2016 and June 2024, 61 patients with symptomatic popliteal cysts underwent arthroscopic internal drainage with the knee positioned in a figure-of-four, while intra-articular lesions were managed with synovial debridement, meniscal repair/formation, and removal of loose bodies. Preoperative magnetic resonance imaging confirmed the presence of popliteal cysts and concomitant intra-articular lesions. Operation time and intraoperative blood loss were recorded. Patient satisfaction was evaluated by Rauschning-Lindgren (R-L) grade, Lysholm scale, visual analogue scale (VAS) score preoperatively and postoperati
