Open reduction and polyaxial plating for stemmed knee periprosthetic fractures: A case series.
Article in SICOT-J, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
introductionStemmed total knee arthroplasty (STKA) periprosthetic fractures (PPFs) are an emerging problem affecting frail patients. Their surgical fixation is challenging, due to intramedullary involvement and poor bone stock. Polyaxial locking plating has yielded good results in implant-related femur fractures. We hypothesized that this treatment would provide similar results for STKA PPFs.
methodsRetrospective analysis of consecutive patients with a femoral PPF or inter-implant fracture around a knee revision stem who had undergone open reduction and periprosthetic-specific polyaxial plate fixation.
resultsWe found 14 cases of mean age 85.4 years. Cerclages were used in 80% of cases. Fixation of a mean 8.6 cortices around the revision stem was achieved, with an overall screw density of 1:2 or 1:3. Four patients lost their ability to walk, while four experienced postoperative local complications. Bone healing was achieved in all except one who died during hospitalization. The 13 remaining survived the first year of follow-up.
conclusionSTKA PPFs are an emerging and challenging problem affecting frail patients. Treatment using polyaxial locking plates provides stable fixation allowing early mobilization despite high complication rates.
