Short-term outcomes after hybrid unicompartmental knee arthroplasty: A retrospective cohort study with minimum 3-year follow-up.
Article in Medicine, 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
This study aims to evaluate the survival rate and short-term clinical outcomes of hybrid unicompartmental knee arthroplasty (UKA). We retrospectively analyzed 155 Oxford phase-3 hybrid UKAs in 155 patients who were followed for more than 3 years. Kaplan-Meier survival curves were generated using revision as an endpoint. Oxford knee score (OKS) and range of motion (ROM) were evaluated for clinical assessment, and radiographs were used to assess implant-related complications. At an average follow-up of 3.6 years (range, 3-6 years), 2 knees required revision. The reasons for revision were bearing dislocation and unexplained pain. The overall survival rate was 98.7% at the 6-year follow-up. The mean OKS decreased from 40.94 ± 4.86 to 14.84 ± 1.39 at the last follow-up (P < .001). The mean OKS showed a significant improvement during the first 2 years. The mean ROM improved from 104.81 ± 10.03° to 114.93 ± 7.51° at the last follow-up (P < .001). The mean ROM increased during the first 3 years. Radiolucent lines were observed in 6 cases at 6 years postoperatively, affecting 4 knees. At 6 years postoperatively, the following complication rates were observed: overall revision rate: 1.33% (2/150); deep vein thrombosis rate: 3.33% (5/150); chronic soft tissue pain rate: 1.33% (2/150); stiffness rate: 0.67% (1/150); prosthesis dislocation rate: 0.67% (1/150); lateral meniscus injury rate: 0.67% (1/150); lateral arthritis progression rate: 2.67% (4/150). Oxford phase-3 hybrid UKA provides good survival rates and clinical outcomes in the short-term follow-up.
