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

purposeΤhe main goal of this study was to compare the clinical results, including the complication rates and patient-reported outcomes, in patients who underwent surgery for recurrent patellar dislocation using different patellar tunnel fixation techniques. This study compared Medial Patellofemoral Ligament (MPFL) reconstruction implant free techniques against ones that used implants.

methodsThe present systematic review was conducted according to the PRISMA guidelines. The literature search was conducted in January 2023. We included patients who underwent isolated MPFL reconstruction for recurrent patellar instability. Patients with confirmed concomitant or prior ipsilateral knee procedures, multiligament injury, severe patellar dysplasia or less than 6 months of follow-up were excluded. MINORS and MCMS scores were used for the assessment of methodological quality.

resultsData from 750 procedures were collected, of which 284 used implants to perform the procedure while in 455 an implant-free technique was used. Patient age at the time of surgery ranged from 11 to 60 years while the follow-up time of the studies ranged between 3 and 108 months. Postoperative Kujala (0.3, p = 0.89) and Lysholm (1.2, p = 0.26) scores were better in the implant-free techniques compared to implant-based. A higher rate of recurrent dislocation (OR 0.51; 95% CI 0.10-2.54, p = 0.4), subluxation (OR 0.20; 95% CI 0.40-0.88, p = 0.019) and stiffness (OR 0.76; 95% CI 0.33-1.72, p = 0.55) was noted in the implant-free techniques, while the implant-based techniques displayed increased incidence of patella fractures (OR 3.12; 95% CI 0.77-12.6, p = 0.09), reoperation (OR 1.69; 95% CI 0.78-3.65, p = 0.17) and infection (OR 2.07; 95% CI 0.46-9.32, p = 0.33).

conclusionThere was no significant difference between the 2 techniques in terms of patient reported outcomes. Regarding complications, MPFL reconstruction using implants demonstrated significant higher rate of patella fractures while the implant free technique showed a greater risk of subluxation.
