Tibiofemoral dislocation after total knee arthroplasty treated successfully with an external fixation device.

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
Tibiofemoral dislocation after primary total knee arthroplasty (TKA) is a rare but potentially devastating complication with various patient-related and surgeon-related predisposing factors. We present the case of an obese 86-year-old woman who sustained an atraumatic posterior tibiofemoral dislocation 3 days after a primary medial-pivot design TKA. The knee remained unstable after reduction, owing to significant hamstring hypertonia. The administration of botulinum toxin injections in the hamstrings resulted in no clinical improvement. The periprosthetic infection workup was negative and the neurological impairment of the patient was excluded. The patient was reoperated with extensive hamstring release and the application of a lateral external fixator. The external fixator was removed 6 weeks postoperatively, and physical therapy was initiated. At 1-year follow-up, the patient had a painless, stable knee with a 0-100° range of motion, without any neuromuscular impairment.
