Functional outcome and cost effectiveness of patellar resurfacing and non-resurfacing in total knee arthroplasty: systematic review and meta-analysis.
Synthesis in Journal of orthopaedic surgery and research, 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
backgroundTotal knee arthroplasty (TKA) is rising globally, with patellar management impacting outcomes. Resurfacing reduces pain and revision rates but poses complications, while non-resurfacing lowers costs but risks persistent pain. This study updates previous meta-analyses by comparing the functional and economic outcomes of both approaches.
methodsThis systematic review and meta-analysis followed PRISMA guidelines. Studies comparing patellar resurfacing and non-resurfacing in TKA with functional outcomes in adults were included. Five databases were searched until February 6, 2024. Two authors independently extracted data and assessed risk of bias. Any disagreements were resolved by a third author. Statistical analysis used a random-effects model, reporting mean differences (MD) and odds ratios (OR) with 95% CI. Sensitivity and subgroup analyses were performed to assess heterogeneity and reliability.
resultsA total of 49 studies (34 RCTs, 15 observational) were included from 963 screened records. Analysis of 22 studies found no significant difference in Knee Society Score (KSS) function between resurfacing and non-resurfacing (MD 2.03; 95% CI 0.58-3.48; p = 0.59, I
conclusionsPatellar resurfacing in TKA significantly reduces anterior knee pain but shows no advantage in KSS function, pain scale, Oxford Knee Score, ROM, or cost-effectiveness. Surgical decisions should be individualized to optimize patient outcomes.
