High survivorship and excellent functional outcome in third-generation patellofemoral arthroplasty.
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, 1 of them a synthesis that pooled 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.
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: This study presents the short- to mid-term implant survival rates, along with the clinical and radiographic outcomes, in a consecutive series of patients who underwent third-generation patellofemoral arthroplasty (PFA) at a non-designer centre. Additionally, it explores the impact of prior surgery on clinical outcomes following PFA. Methods: A retrospective analysis of prospectively collected data was conducted for 27 PFAs performed in 23 patients between 2016 and 2023 using the Gender Solutions® Patello-Femoral Joint System. Patients had a mean follow-up of 4.3 years, with clinical assessments including the Oxford Knee Score (OKS), Visual Analogue Scale (VAS), Forgotten Joint Score (FJS), and activity levels (TAS, UCLA). Implant survivorship was analysed using Kaplan-Meier estimators, with endpoints of revision and reoperation. Results: The mean age at time of surgery was 51.7 ± 10.5 years, with 92.6% of patients being women. The mean body mass index (BMI) was 28.3 ± 4.5. The 5-year implant survival rate was 100% for revisions and 96.3% for reoperations. Statistically significant improvements were observed in OKS (24.7 ± 8.0 to 39.2 ± 8.3, Conclusion: The short- to mid-term results following third-generation PFA demonstrated high survivorship and excellent clinical outcomes in an independent series. Prior surgery and obesity were not associated with poorer clinical outcomes, supporting the consideration of PFA for these patients when appropriately indicated. Level of Evidence: Level III, retrospective cohort study.
