Postural stability after patient-specific interpositional knee spacer or total knee arthroplasty: a comparative study.
Article in International orthopaedics, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeTotal knee arthroplasty provides excellent results concerning functional demands, patient satisfaction and range of motion. Short-term results after implantation of patient-specific knee spacers also show encouraging results. We hypothesised that patient-specific interpositional devices provide better proprioception and postural stability by preserving the whole bone stock and both cruciate ligaments.
methodsIn this study we compared functional results, proprioception and postural stability 16 months after 20 consecutive patient-specific interpositional device implantations of the knee (group A) and 20 consecutive total knee arthroplasties (group B). Patients were evaluated using the Knee Society Score (KSS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC). Postural stability was analysed during single leg stance on a force platform (Biodex).
resultsThere were no significant differences between both groups concerning functional results 16 months after the procedure. Concerning postural stability, significant differences were found between both groups. Comparing the operated-on and non-operated-on sides in single leg stance, the operated-on leg gained the same stability as the non-operated-on side in both groups.
conclusionsThe successful treatment of knee osteoarthritis can restore postural stability to the level of the unaffected side-independent from the implanted devices and with preservation of soft tissue and bone stock. Superior postural stability in joint-preserving patient-specific interpositional knee devices compared with total knee arthroplasty had to be attributed to the different age of both groups.
