Predicting unicompartmental arthroplasty success: a three year Indian study.
Article in International orthopaedics, 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
purposeThis study evaluated the three year clinical outcomes and predictors of success for unicompartmental knee arthroplasty (UKA) in an Indian population.
methodsTwenty patients with medial compartment osteoarthritis (≥ Ahlbäck grade 2) underwent UKA. American Knee Society Score (AKSS), Oxford Knee Score (OKS), and Visual Analogue Scale Score (VAS) were assessed at baseline, two weeks, six weeks, three months, and three years. Postoperative Hip Knee Ankle angle (HKA) and the Knee Joint Line Obliquity angle (KJO) were measured.
resultsAt three years, UKA led to significant improvements in knee health, function, and pain. AKKS improved from 62.20 ± 5.27 to 90.60 ± 3.81, OKS from 37.00 ± 1.55 to 19.15 ± 1.93, and VAS from 8.45 ± 0.69 to 2.40 ± 0.59 (all P < 0.05). Preoperative VAS was significantly correlated with both preoperative and postoperative outcomes of knee health and function (preoperative and three year AKSS and OKS), and limb alignment (HKA and KJO). Preoperative AKSS correlated with postoperative knee health and functional outcomes (3-year AKSS and OKS), pain levels (3-year VAS), and limb alignment (KJO).
conclusionsIn this study of an Indian population, UKA demonstrated significant, sustained clinical improvements over three years, with no implant-related complications. In our cohort, preoperative pain and knee health significantly predicted outcomes. These findings suggest that preoperative assessment and optimization of both pain and knee health may potentially enhance the postoperative outcomes after UKA.
