Good functional outcomes and radiological union following arthroscopic knotless anchor fixation of tibial spine avulsion fractures: A prospective clinical study.

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
Purpose: Tibial spine avulsion fractures compromise ACL function and are common in children and adolescents. Traditional fixation methods may risk physeal injury and intra-articular damage. Arthroscopic suture-based techniques offer a minimally invasive, physeal-sparing alternative. Methods: Twenty-five patients (mean age: 19 years) with type II-IV tibial spine fractures underwent arthroscopic anterior row suture fixation using knotless anchors. Functional outcomes as Lysholm, Internation Knee Documentation Committee rating score (IKDC), Range of motion (ROM), stability, and radiological healing were assessed over 24 months. Results: All patients achieved radiographic union (mean: 16 weeks). Final follow-up showed restoration of pre-injury Lysholm (94 ± 5 to 93.6 ± 0.8), IKDC (84 ± 7 to 83.9 ± 0.7), and ROM (142°-140°). No instability, growth disturbance, or hardware-related complications were observed. Conclusion: This technique provides stable fixation, preserves the physis, and avoids intra-articular hardware. Functional and radiological outcomes were excellent, supporting arthroscopic suture fixation as a safe and effective option for tibial spine avulsion fractures. Level of Evidence: Level III, prospective study.
