Comparison of patient reported outcomes after Triathlon(®) and Kinemax Plus prostheses.
Synthesis in Annals of the Royal College of Surgeons of England, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionThe Triathlon(®) (Stryker, Kalamazoo, MI, US) total knee replacement was designed to improve patient function and survivorship. The aim of this study was to determine whether the Triathlon(®) prosthesis produces better patient reported outcomes than a previous design by the same manufacturer, the Kinemax Plus.
methodsThe outcome of 233 knees of patients with a mean age of 68 years (range: 40-80 years) who received the Kinemax Plus prosthesis were compared with the outcomes of 220 knees of patients with a mean age of 70 years (range: 42-90 years) who received the Triathlon(®) prosthesis. Data were collected via postal questionnaire prior to surgery as well as at 8-12 weeks and at 1 year following surgery. Validated questionnaires were used including the WOMAC(®) (Western Ontario and McMaster Universities) pain and function scales, the Knee injury and Osteoarthritis Outcome Score quality of life scale and the self-administered patient satisfaction scale.
resultsThis study found that patients who had the Triathlon(®) prosthesis had significantly better pain relief (p<0.0001), function (p=0.028), knee related quality of life (p<0.0001) and satisfaction (p=0.0003) at three months after surgery than those who received the Kinemax Plus prosthesis. In addition, knee related quality of life (p=0.002) and satisfaction (p=0.021) were significantly higher at one year after surgery in Triathlon(®) PATIENTS:
conclusionsThe findings suggest that return to function and reduction in pain may occur more quickly in patients with a Triathlon(®) prosthesis than in those with the Kinemax Plus.
