[Are the results of total knee arthroplasty after high tibial osteotomy worse?]
Article in Der Orthopade, 2021. 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
backgroundIn some cases, total knee arthroplasty (TKA) following high tibial osteotomy (HTO) is necessary. HTO can adversely affect anatomy and alignment resulting in more complicated and challenging TKA surgery. The aim of this study was to investigate whether patients having undergone HTO benefit from TKA to the same extent as patients with primary osteoarthritis of the knee.
methodsA total of 44 patients after HTO and 1703 patients with primary osteoarthritis of the knee were identified in the local registry. To reduce confounders, a 1:1 propensity score matched-pair analysis (age, gender, BMI, comorbidities) was carried out in patients with a 5-year follow-up. This resulted in 35 matched pairs, which were compared for knee function, pain level, satisfaction and perioperative data (operative time, implant type, complications) and revisions.
resultsPatients having undergone HTO had no significant differences in knee function prior and 5 years after surgery but a significantly higher pain level. Despite the higher pain level before and after TKA, there was a similar satisfaction with the result of the surgery. The operative time for TKA was significantly longer after HTO and modular implants with stem and wedges were used significantly more often. The two cohorts did not differ with respect to complications within the first 3 months after surgery. The revision rate within 5 years was not increased in patients after HTO.
conclusionPatients having undergone HTO achieved a similar knee function in comparison to patients with primary osteoarthritis of the knee after TKA. However, a higher pre- and postoperative pain level was recorded in patients following HTO. The surgical effort was significantly higher after HTO.
