Image-based robotic-assisted patellofemoral arthroplasty for isolated patellofemoral osteoarthritis: Short-term survivorship, clinical and radiographic outcomes.

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
introductionPatellofemoral arthroplasty (PFA) is a valuable option for selected patients with isolated patellofemoral osteoarthritis (PFOA), where component positioning and patellar tracking are critical determinants of outcome. Robotic assistance may improve these aspects, but available literature remains limited. This study evaluated early survivorship, complications, and reoperations after image-based robotic-assisted PFA (RA-PFA). Secondary aims were to assess clinical outcomes, return to sport, radiographic patellofemoral parameters, and agreement between planned and final implanted component position.
methodThis retrospective single-center study included consecutive patients treated with RA-PFA for isolated PFOA between November 2021 and October 2024, with a minimum clinical and radiographic follow-up of 12 months. Primary outcomes were implant survivorship, reoperation-free survivorship, and postoperative complications. Secondary outcomes included Knee Society Score (KSS), range of motion (ROM), return to sport, radiographic patellofemoral parameters, and MAKO-derived plan-to-execution agreement. Kaplan-Meier analysis was used to assess survival.
resultsThirty patients (35 knees; 5 bilateral cases) were included, with a mean age of 61.3 ± 12.2 years and mean body mass index of 25.3 ± 5.2 kg/m DISCUSSION: Image-based RA-PFA was associated with encouraging early survivorship, substantial functional gains, preserved knee motion, and improved radiographic patellofemoral alignment at short-term follow-up. However, the specific contribution of robotic assistance cannot be determined in the absence of a conventional control group. LEVEL OF EVIDENCE: Level IV.
