Patellar resurfacing in knee arthroplasty: A comprehensive review and meta-analysis.
Article in World journal of orthopedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPatellar resurfacing in knee arthroplasty remains a contentious issue, with various strategies including routine, selective, and non-resurfacing approaches. This review and meta-analysis aim to assess the incidence of patellar resurfacing, revision rates, patient satisfaction, and relevant knee scores associated with each method.
aimTo determine the comparative effectiveness of routine, selective, and non-resurfacing strategies in patellar resurfacing within knee arthroplasty by evaluating incidence rates, revision rates, patient satisfaction, and knee function scores.
methodsA systematic review spanning from 1990 to 2024 was conducted using PubMed, Embase, and Cochrane Library databases. Studies reporting on the incidence of patellar resurfacing, revision rates, patient satisfaction, and relevant knee scores were included. Data from esteemed world registries such as the Australian Orthopaedic Association National Joint Replacement Registry, the National Joint Registry for England, Wales, Northern Ireland, and the Isle of Man and Danish Knee Arthroplasty Registry among others, were meticulously examined. Meta-analysis was employed to derive pooled estimates and 95% confidence intervals.
resultsAnalysis of data sourced from diverse world registries and literature sources unveiled significant disparities in the incidence of patellar resurfacing across different geographic regions and healthcare institutions. For instance, the incidence of routine patellar resurfacing ranged from 60% to 90% in some regions, while in others, it was as low as 30% to 50%. The meta-analysis indicated that routine resurfacing was associated with a lower revision rate of 3.5% (95%CI: 2.8%-4.2%) compared to non-resurfacing approaches, which exhibited a higher revision rate of 6.8% (95%CI: 5.5%-8.1%). Patient satisfaction outcomes showed variability, with routine resurfacing demonstrating higher mean satisfaction scores in functionality, pain relief, and stability categories.
conclusionThe findings underscore the complexity of patellar resurfacing in knee arthroplasty and highlight the need for continued research to refine clinical practice. Future studies should prioritize prospective randomized controlled trials comparing different patellar resurfacing techniques using standardized outcome measures. Longitudinal studies with extended follow-up periods are necessary to evaluate the long-term outcomes and durability of various patellar resurfacing strategies. Collaborative efforts among multidisciplinary teams will be essential to conduct high-quality research that can provide actionable insights and improve patient outcomes.
