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: Patellar instability is common in skeletally immature patients; however, the presence of open physes presents unique challenges to surgical management. Purpose: To (1) assess the safety and efficacy of anatomic medial patellofemoral ligament reconstruction (MPFL-R) in a skeletally immature patient population at short-, mid-, and long-term follow-up and (2) determine the influence of patient factors and surgical and radiographic characteristics on the risk of recurrent instability and clinical outcomes after surgery. Study Design: Case series; Level of evidence, 4. Methods: A retrospective analysis was conducted of the records of skeletally immature patients who underwent primary, anatomic MPFL-R with concomitant procedures at a single academic institution between 2010 and 2019. Patients with <2 years of follow-up were excluded. Demographic data, preoperative radiographic parameters, and surgical details were collected through chart review. Recurrent instability, growth disturbance, and return-to-sport rates were documented via telephone follow-up. The final follow-up included assessment of Kujala, Lysholm, and International Knee Documentation Committee (IKDC) scores. Subgroup analysis focused on patients undergoing isolated MPFL-R. Results: A total of 54 knees in 51 skeletally immature patients with a mean age of 15.6 years (range, 10-18 years) were available for analysis. At a mean follow-up of 8.15 years (range, 55-152 months), 4 of 54 (7.4%) knees experienced subsequent patellar subluxation events. There were no confirmed patellar dislocations, and no patients underwent reoperation for patellar stabilization or growth disturbance. At the final follow-up, the mean Kujala, Lysholm, and IKDC scores were 85.7 (range, 11-100), 83.6 (range, 14-100), and 76.1 (range, 10-95.4), respectively. Patients with a younger age at the time of surgery (hazard ratio, -0.83; 95% CI, -1.53 to -0.14; Conclusion: Anatomic MPFL-R paired with concomitant procedures as indicated is a safe, efficacious, and durable treatment option for lateral patellar instability in adolescent patients with an open or partially open distal femoral physis.
