Patellar resurfacing as a prognostic variable in total knee arthroplasty: a two‑decade retrospective cohort (2000‑2020).
Article in BMC musculoskeletal disorders, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundThe impact of patellar resurfacing (PR) on long-term outcomes following primary total knee arthroplasty (TKA) remains a topic of debate.
methodsThis study examined a retrospective cohort of 334 primary total knee arthroplasties (TKAs) performed between 2000 and 2020 at a specialized hospital. The surgeries were conducted from January 2000 to December 2020, allowing for a maximum potential follow-up period of 20 years. The primary endpoint assessed was the rate of any-cause revision. Secondary endpoints included anterior knee pain, aseptic loosening, patient-reported outcomes (Western Ontario and McMaster Universities Osteoarthritis index and Oxford Knee Score), and complications. Kaplan-Meier estimates and multivariable Cox models, adjusted for age, body mass index, and inflammatory arthropathy, were utilized.
resultsPR yielded an absolute risk reduction (ARR) of 83% for anterior knee pain (2.2% in the PR group vs. 85.2% in the WPR group; number needed to treat ≈ 1–2) and an ARR of 7.5% for aseptic loosening (4.4% vs. 11.9%; NNT = 14). The overall revision rates were 5.1% for PR and 6.7% for WPR, demonstrating no significant differences (hazard ratio 0.65, 95% confidence interval 0.30–1.42).
conclusionsPatellar resurfacing significantly alleviates anterior knee pain and decreases the risk of aseptic loosening without raising the overall revision rate. These findings advocate for a selective resurfacing approach targeting patellae at a higher risk of pain rather than adopting a routine or universal resurfacing strategy.
trial registrationNot applicable, this study is an observational retrospective cohort; no prospective registration was required.
