Outcome after isolated medial patellofemoral ligament reconstruction is dependent on age but not on body mass index or gender.
Article in Journal of experimental orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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: Medial patellofemoral ligament (MPFL) reconstruction is the most used surgical technique in the treatment of patellofemoral instability. However, the role of patient specific factors like age, sex and body mass index (BMI) at surgery is being increasingly discussed. The aim of this study was to study the influence of these factors with regards to functional outcomes and redislocation rates. Methods: All patients with patellofemoral instability, who were treated with isolated MPFL reconstruction surgery between 01/2017 to 01/2022, were included. Patients with pathologic risk factors, high-grade cartilage damage, prior surgeries and age <14 years were excluded. Demographic information and information concerning surgery, complications and history were collected. Patient reported outcome measures (PROMs) were collected preoperatively, after 6 and 12 months postoperatively and at final follow-up using multiple standardised scores (knee injury and osteoarthritis outcome score, International Knee Documentation Committee [IKDC], Tegner activity scale, Kujala, BANFF). Results: Of the 62 patients included in this study 42 (67.7%) were female with a mean age of 24.8 ± 7.6 years and a mean BMI of 24.5 ± 4.7 kg/m Conclusion: Older age at the time of surgery has a highly significant negative correlation with the functional outcome after isolated MPFL reconstruction. Therefore, surgeons must be highly vigilant and identify high-risk patients even before surgery and necessary MPFL reconstruction should not be delayed. Level of Evidence: Level III, retrospective cohort study.
