Total knee arthroplasty with metaphyseal sleeves for acute tibial plateau fractures.
Article in Bone & joint open, 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
Aims: Total knee arthroplasty (TKA) allows immediate weightbearing and avoids challenges associated with secondary arthroplasty following conservative management or failed fixation of tibial plateau fractures (TPFs). Metaphyseal sleeves may overcome the limitations of conventional implants by addressing issues of deficient bone stock and inadequate proximal fixation in the fracture zone. Methods: We conducted a retrospective case series of patients undergoing TKA with metaphyseal sleeves for acute TPFs at a single tertiary centre between January 2019 and June 2025. Demographic details, injury characteristics, clinical outcomes, and complications were extracted from electronic records. Results: A total of 16 patients were included (mean age 73.8 years (SD 6.0), 93.8% female). Of these patients (87.5% (n = 14/16) were osteoporotic, and 37.5% (n = 6/16) had pre-existing osteoarthritis. The median follow-up was 12 months (IQR 3 to 72). Immediate weightbearing was achieved in all. Radiographs in all patients showed metaphyseal sleeve integration and no subsidence by three months. One patient was followed up at six years showing no adverse radiological signs. Mean knee range of motion improved from 90.7° at sixweeks to 108.1° at final follow-up. Complications occurred in 25.0% of patients (n = 4/16), most commonly wound-related (n = 2/16). Two patients (12.5%) required further surgical intervention. Conclusion: TKA with metaphyseal sleeves has a role in selected elderly patients with TPF not amenable to reconstruction. It addresses fixation failure in TPF and enables early mobilization with acceptable outcomes.
