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

purposeMedial patellofemoral ligament reconstruction (MPFLR) is often indicated in athletes with lateral patellar instability to prevent recurrence and allow for a successful return to play. In this patient population, the ability to return to play is one of the most important clinical outcomes. The purpose of the current study was to analyze the characteristics of patients who were unable return to play following MPFL reconstruction.

methodsA retrospective review of patients who underwent MPFL reconstruction and subsequently did not return to play after a minimum of 12-months of follow-up was performed. Patients were evaluated for their psychological readiness to return to sport using the MPFL-Return to Sport after Injury (MPFL-RSI) score, which is a modification of the ACL-RSI score. A MPFL-RSI score > 56 is considered a passing score for being psychologically ready to return to play. Additionally, reasons for not returning to play including Visual Analog Scale for pain (VAS), Kujala score, satisfaction, and recurrent instability (including dislocations and subluxations) were evaluated.

resultsThe study included a total of 35 patients who were unable to return to play out of a total cohort of 131 patients who underwent MPFL reconstruction as treatment for patellar instability. Overall, 60% were female with a mean age of 24.5, and a mean follow-up of 38 months. Nine patients (25.7%) passed the MPFL-RSI benchmark of 56 with a mean overall score of 44.2 ± 21.8. The most common primary reasons for not returning to play were 14 were afraid of re-injury, 9 cited other lifestyle factors, 5 did not return due to continued knee pain, 5 were not confident in their ability to perform, and 2 did not return due to a feeling of instability. The mean VAS score was 1.9 ± 2.3, the mean Kujala score was 82.5 ± 14.6, and the mean satisfaction was 76.9%. Three patients (8.7%) reported experiencing a patellar subluxation event post-operatively. No patient sustained a post-operative patellar dislocation.

conclusionFollowing MPFL reconstruction, patients that do not return to play exhibit poor psychological readiness with the most common reason being fear of re-injury. LEVEL OF EVIDENCE: IV.
