Minimum ten years follow-up of total knee arthroplasty using morphometric implants in patients with osteoarthritis.
Article in International orthopaedics, 2026. 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
purposeThe aim of this study was to report the 10-year clinical and radiological outcomes, survivorship, and patient-reported results of the Persona posterior-stabilized (PS) total knee arthroplasty (TKA) performed in a single centre.
methodsThis retrospective cohort study was based on a prospectively institutional database. A total of 293 primary Persona PS TKAs performed between 2012 and 2015 were identified. After applying inclusion and exclusion criteria, 185 knees (168 patients) were available for analysis at a minimum follow-up of ten years. Clinical evaluation included the Knee injury and Osteoarthritis Outcome Score (KOOS) and the 2011 Knee Society Score (KSS). Radiological assessment consisted of the hip-knee-ankle (HKA) angle. Implant survivorship was analyzed using Kaplan-Meier methods.
resultsAt 10 years, Kaplan-Meier survivorship for revision for any reason was 94.1% (95% CI 90.3-97.9%). Four revisions were performed (2 infections, 2 aseptic loosening). Mean KOOS scores improved significantly from preoperative to ten year follow-up (Pain 48→86; Symptoms 45→84; ADL 50→89; Sport 25→72; QoL 30→82; all p < 0.001). The KSS 2011 domains also significantly improved. The mean postoperative HKA angle was 179° ± 2°, with 7.8% of knees outside ± 3° from neutral. No radiographic evidence of radiolucent lines, osteolysis, or loosening was observed.
conclusionAt ten years, the Persona PS knee system demonstrated excellent survivorship and durable functional results comparable to other contemporary TKA designs. Further comparative studies are required to determine whether its morphometric concept provides additional clinical benefit. LEVEL OF EVIDENCE: IV Retrospective cohort study.
