Increased turn/amplitude parameters following subvastus approach in total knee arthroplasty.
Article in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers, 1 of them a synthesis that pooled it.
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
purposeTo compare the improvement of the vastus medialis component of the quadriceps muscle electrophysiologically after the subvastus and medial parapatellar approaches in total knee arthroplasty (TKA).
methodsA total 26 patients that underwent primary unilateral in TKA were included into the study. TKAs were carried out via subvastus approach in 15 patients, while 11 patients were operated via medial parapatellar approach. The electrophysiological evaluations were carried out blindly with regard to the type of the surgical approach before the operation and at 6th week post-operatively. Non-surgical side was also evaluated as a control. Assessments were patellar tendon reflex analysis, motor unit potential analysis and interference pattern analysis (IPA) including turn-amplitude analysis and IPA during maximum contraction.
resultsWhen they were compared to the pre-operative values, "the total mean amplitude" and "the mean turn/sec" parameters were significantly increased in group of subvastus approach (p = 0.017 and p = 0.009, respectively) at the post-operative 6th week. We would not be able to find any difference regarding the other electrophysiological parameters. There was also no significant difference between groups.
conclusionIf there was no significant difference in all the electrophysiological parameters, the increase in turn-amplitude analysis in the group of subvastus approach would be considered as an indicator of a faster functional improvement of knee extensor mechanism in these cases.
