Simultaneous bilateral total knee replacement in a patient with achondroplasia and severe varus deformity: a case report.
Article in Journal of surgical case reports, 2025. 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
We present a unique case of a 61-year-old female with achondroplasia and end-stage osteoarthritis of both knees who presented with severe pain and bilateral varus deformities of over 40 degrees. The patient underwent single-stage bilateral total knee arthroplasty (TKA) using cemented rotating-hinge implants with long stems. At 5-year follow-up, the patient has neutral limb alignment, pain-free ambulation without assistive devices, and stable implants on radiographs. This is one of the first reported cases of simultaneous bilateral TKA in a patient with achondroplasia and extreme bilateral varus deformity, highlighting how successful correction can be achieved using hinged implants and careful surgical planning, underscoring the feasibility of one-stage bilateral intervention in this rare and challenging scenario.
