Enhanced Surgical Outcomes of Popliteal Cyst Excision: A Retrospective Study Comparing Arthroscopic Debridement with and without Methylene Blue Injection

Abstract

cystectomy. Surgical time of cyst resection, postoperative bruising extent, complication rate, and cyst recurrence rate of the 2 groups were compared. Results: The MB group had a faster surgical cyst removal time (16.5±1.5 min) than the control group (24.5±1.6 min; P <0.05). The MB group had less postoperative bruising (1 case, 4.5%) than the control group (5 cases, 25%; P <0.05). The surgical results were similar in both groups, with a Lysholm score of 87.23±1.80 in the MB group and 87.23±1.62 ( P >0.05) in the control group. Conclusions: This study showed that preoperative injection of MB for popliteal cysts before arthroscopic debridement improved cyst localization and ease and accuracy of surgery and reduced operative time, adjacent tissue damage, postoperative complications, and recurrence rate.
