Mid-term outcomes of a novel liner design in kinematically-designed cruciate-retaining total knee arthroplasty.
Article in World journal of orthopedics, 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
backgroundMedial dished (MD) liner designs for cruciate-retaining (CR) total knee arthroplasty (TKA) are a relatively novel development. MD tibial inserts have a more constraining medial side, which allows for more similar kinematics and function to a native knee.
aimTo evaluate the clinical results and patient-reported outcomes after CR TKA procedures utilizing a kinematically designed medial dish system.
methodsA multicenter, retrospective cohort review of 139 primary elective TKAs utilizing a kinematically designed CR Knee System (JOURNEY™ II CR MD; Smith and Nephew, Memphis, TN, United States) at three different institutions with a minimum of two years of follow-up. Demographic information, clinical outcomes, and patient-reported outcome measures were collected and analyzed.
resultsWith up to 3.7 years from surgery, overall implant survivorship was 98.6%. There were significant postoperative increases in the average Knee Injury and Osteoarthritis Outcome Score for Joint Replacement scores (17.4 at 6 months, 26.1 points at two years or more,
conclusionThe combination of high implant survivorship and substantial improvements in patient-reported outcome measures suggests that the medial dish tibial insert represents a safe and effective option within TKA. Additional investigation is necessary to evaluate the long-term survivorship of this design.
