Biomechanical Comparison of Knotless Suture Anchor Fixation Versus Transosseous Suture Button Fixation for Posterior Medial Meniscal Root Tears.

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
Background: Posterior medial meniscal root (PMMR) tears have been shown to create a biomechanically unfavorable environment for knee cartilage. While various PMMR repair methods have been shown to restore normal knee biomechanics, there is little consensus on the ideal repair technique. Purpose: To compare PMMR repair using a knotless all-suture anchor versus traditional transosseous fixation using a suture button. Study Design: Controlled laboratory study. Methods: Ten matched pairs of fresh-frozen cadaveric knees were biomechanically tested in intact, torn, and surgically repaired conditions. One limb from each donor was repaired using a traditional suture and bone tunnel technique (control group), while the contralateral limb was repaired with a knotless all-suture anchor (anchor group). The limbs were distributed equally between the 2 surgical procedure groups, so that each group contained a nearly equal number of right and left knees. Results: There were no significant differences in normalized contact area or normalized contact pressure between control and anchor groups at 0°, 30°, or 60° of knee flexion. Contact pressure returned to near-intact values at 0°, 30°, and 60° for both groups. This was also the case at 90° for the anchor group. However, the control group did not return to intact values at 90°, resulting in a significantly ( Conclusion: At time zero, knotless all-suture repair of PMMR tears performed biomechanically similarly or better than transosseous suture button fixation at 0°, 30°, and 60° of flexion, with significantly improved contact area and contact pressure at 90° of flexion. Thus, knotless all-suture anchor repair may represent a viable alternative technique for PMMR repair. Clinical Relevance: The knowledge that knotless all-suture anchor repair performed as well as or better than a more traditional technique allows for a technically simpler surgery, which precludes the need for drilling through the tibia.
