1 · What the graph read from it

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.

2 · The registry

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: Medial patellofemoral ligament (MPFL) reconstruction is an established treatment for recurrent patellar instability. Techniques requiring patellar drilling (tunnels or sockets for fixation) may increase the risk of iatrogenic patellar fracture. Purpose/Hypothesis: The purpose was to compare clinical outcomes and complications after MPFL reconstruction using a superficial quadriceps tendon (QT) graft versus a hamstring tendon (HT) graft) fixed with patellar all-suture anchors. It was hypothesized that the superficial QT technique would yield patient-reported outcomes comparable with the HT technique, with a different profile of patella-related complications. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective, 2-center review identified 47 patients (49 knees) who underwent MPFL reconstruction for recurrent patellar instability. A total of 23 knees were reconstructed with a patellar tunnel-free superficial QT graft and 26 with an HT graft fixed to the patella using suture anchors and to the femur at the Schöttle point. Patients with prior patellar surgery, periarticular fractures, or insufficient follow-up were excluded. Preoperative radiographic parameters and patient-reported outcomes (Kujala, Lysholm, Tegner, and visual analog scale [VAS] for pain) were recorded. The primary outcome was the Kujala score at final follow-up; secondary outcomes included other scores and complications (recurrent instability, patellar fracture, positive apprehension, and range-of-motion limitation). Results: Groups were comparable in demographics and radiographic measures at baseline. The mean follow-up duration was 59.8 months in the QT group and 50.7 months in the HT group. No significant between-group differences were observed in Kujala, Lysholm, Tegner, or VAS pain scores (all Conclusion: Superficial quadriceps and HT autografts provide similarly favorable clinical outcomes and complication rates in MPFL reconstruction. No patellar fractures occurred in the QT group; however, fracture rates were not statistically different between groups and the study was underpowered for rare events. The QT technique avoids patellar drilling and may be considered in patients perceived to be at higher risk for patellar fracture.
