8-11 year results of LARS augmented hamstring in anterior cruciate ligament reconstruction surgery: Incidence of synovitis and failures.

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: Anterior cruciate ligament (ACL) injury account for the majority of sport related knee ligament injuries and ACL reconstruction surgery is one of the most performed operations in the young adult population. Various graft types have been used to reconstruct the ACL, however there is no consensus on the best option. Concerns about quality and size of the graft and its effects on success of the reconstruction remain. Synthetic grafts have also been used for a long time as a substitute or to augment biological grafts however, concerns about early failure and particle related synovitis have limited their intra-articular use. The most common synthetic graft option still in use is the Ligament Augmentation and Reconstruction System (LARS). Method: The study is a case controlled retrospective comparison of 102 consecutive cases reporting 8-11 year results in relation to clinical outcomes revision rates and synovitis of ACL reconstruction surgery using LARS synthetic grafts as an augment when compared with hamstring graft alone. Result: The study found a mean follow up was 9 years and one month (8-11 years) and revision rate was 5.7 % for the LARS augmented group and 12.5 % for the Hamstring group, but not significantly different, odds ratio 0.4 (C.I: 0.1179-1.555, p = 0.255). LARS augmented autograft ACL reconstruction had similar results at 8-11 years when compared to autograft only reconstructions. No synovitis was noted in either group. Conclusion: LARS ensures an appropriately sized graft, is safe and not associated with synovitis in our cohort at 8-11 year follow up.
