    IntroductionClosed suction drainage is an established procedure in arthroscopic surgery. It is intended to reduce the retention of wound and irrigation fluids, which form the basis for postoperative swelling, pain, and infection. However, currently, there is no scientific review of the actual benefit of this procedure.MethodsBetween 2020 and 2021, 84 patients (53 males, 31 females; mean age: 42 years) were prospectively randomised into this study. The patients underwent arthroscopic surgery of the ankle joint with (group A) or without (group B) insertion of a closed suction drain (42 patients per group). Assessments included upper ankle swelling using the figure-of-eight-20 method, pain preoperatively and 48 h postoperatively, and unexpected events within 6 weeks postoperatively.ResultsThe measurements performed 48 h postoperatively showed a mean circumferential increase of 1.38 cm (1.48 and 1.28 cm in groups A and B, respectively; p > 0.05) in all patients. The mean pain at rest, assessed using the visual analogue scale (maximum 10 points), was 2.7 and 2.4 in groups A and B, respectively (p > 0.05). Overall, two minor complications occurred: residual swelling in group A and persistent limitation of movement in group B. The average length of hospital stay was 2.4 days (p > 0.05).ConclusionsBased on the available data, the routine insertion of a closed suction drainage at the upper ankle does not offer any objective benefit and must be considered obsolete. From both a medical and an economic point of view, the decision to conduct this procedure should be justified on an individual basis.Level Of EvidenceLevel I, prospective randomised trial.© 2021.
