A comparative study of arthroscopic treatment of popliteal cyst with internal drainage and internal drainage combined with cyst wall resection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeTo compare the clinical outcomes of arthroscopic internal drainage (AID) and arthroscopic internal drainage combined cyst wall resection(AID + CWR) in treatment of the popliteal cysts.
methodsIn this prospective randomized study, 60 patients (October 2022) at Beijing Tsinghua Changgung Hospital were divided into Group A (AID, n = 30) and Group B (AID + CWR, n = 30). Operative duration, blood loss, intra-articular pathologies, and complications were recorded. Outcomes included Visual analog scale (VAS) score, Rauschning-Lindgren (R-L) grade, Lysholm score, and cyst volume reduction on magnetic resonance imaging (MRI).
resultsWith mean follow-up of 12.2 ± 1.2 months, baseline characteristics were comparable (P > 0.05). Group B had longer operative time and greater blood loss (both P < 0.05). Final outcomes showed equivalent functional scores (Lysholm, R-L; P > 0.05), but Group B achieved significantly higher complete cyst resolution rates (Group A 46.4% vs. Group B 74.1%, P = 0.032) on MRI. Complication rates (e.g., ecchymosis: Group A 6.7% vs. Group B 20%, P = 0.255) did not differ significantly.
conclusionAlthough requiring slightly longer operative time and greater blood loss, cyst wall resection with drainage provides superior cyst resolution, making it preferable for patients seeking optimal results or those with cyst inflammation, loose bodies, or multi-compartment cysts.
