The effect of silicone ring tourniquet in anterior cruciate ligament reconstruction: a retrospective comparative study.
Article in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study aimed to compare the clinical outcomes and postoperative complications between silicone ring tourniquets and pneumatic tourniquets in arthroscopic anterior cruciate ligament (ACL) reconstruction surgery.
methodsThis retrospective study enrolled 200 patients who underwent unilateral knee ACL reconstruction between April 2022 and April 2023. Patients were grouped according to the type of tourniquet used. Preoperative and postoperative hemoglobin levels, total blood loss, operative time, tourniquet application time, length of postoperative hospital stay, and frequency of dressing changes were evaluated. Pain was assessed using a visual analog scale (VAS) preoperatively and on postoperative days 1–3. Knee circumference was measured to evaluate knee swelling. In addition, all patients underwent 6-month follow-up to assess complications and knee joint functional recovery.
resultsPatients in the silicone ring tourniquet group had a shorter postoperative hospital stay (P = 0.011) and lower postoperative day 1 pain scores (P = 0.003). No statistically significant between-group differences were observed in operative time, hemostasis efficacy, frequency of dressing changes, knee swelling, complications rates or 6-month follow-up knee functional scores (all P > 0.05).
conclusionIn arthroscopic ACL reconstruction, the silicone ring tourniquet was superior to the pneumatic tourniquet in postoperative day 1 VAS pain scores and length of postoperative hospital stay, with no significant difference in complication incidence between the two groups. However, this study is limited by its non-randomized design, sample size and statistical power, and as the pain difference did not reach the minimal clinically important difference threshold, the present conclusion is preliminary and requires validation in large-sample, multicenter studies. LEVEL OF EVIDENCE: Level III retrospective comparative study.
