[Changes of patella position after closed and open wedge high tibial osteotomy: review of the literature].
Synthesis in Der Orthopade, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
aimHigh tibial osteotomy (HTO) is an established treatment for varus osteoarthritis of the knee. The correction can be achieved by lateral closed wedge HTO or medial open wedge HTO techniques. Both techniques can change the patella position which influences alignment of the patella. Patella infera may compromise the result of secondary total knee prosthesis. An analysis of the current literature was carried out focusing on changes of patella position after HTO.
methodA literature search was performed in PubMed which identified 15 relevant publications and the Insall-Salvati-index, the Blackburne-Peel-index and the Caton-Deschamps-index were analyzed.
resultsResults after closed wedge HTO: the Insall-Salvati-index decreased in 7 papers, increased in 3 papers and was unchanged in 1 paper. The Blackburne-Peel-index increased in 5 papers and decreased in 2. The Caton-Deschamps-index decreased in 4 papers and increased in 2 papers. Results after open wedge HTO: the InsalI-Salvati-index decreased in 5 papers and increased in 2. The Blackburne-Peel-index decreased in all 7 papers and the Caton-Deschamps-index decreased in all 5 papers. The results of these studies vary significantly and there was a tendency to patella infera in both techniques. The Blackburne-Peel-index and the Caton-Deschamps-index may be biased by slope changes but the exact effect is not yet known. The Insall-Salvati-index seems to be independent of slope changes. The effect of different rehabilitation concepts on patella height is not known.
conclusionThe clinical relevance of the observed changes in patella position must be clarified by prospective studies with strict criteria.
