Joint line elevation after TKA is higher in patients with metaphyseal deformity: a prospective study.
Article in Archives of orthopaedic and trauma surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionJoint level restoration is crucial for the success of total knee arthroplasty. The aim of this study was to evaluate joint line estimation methods between two patient groups with mild to moderate or advanced varus deformities. MATERIAL AND
methodsPatients were classified according to the Parvizi Classification as Type IA or Type M. Measurements were taken of distances from the fibular head, medial and lateral epicondyles, and adductor tubercle to the joint line, and the adductor ratio (AR) was calculated. Joint line elevation was measured postoperatively. Two years after surgery, the Hospital for Special Surgery (HSS) scores were recorded at the end of 2 years postoperatively.
resultsEvaluation was made of 68 patients, comprising 58 (85.3%) females and 10 (14.7%) males with a median age of 65 years (IQR: 25-75; 62-69). Although preoperative AR values were significantly lower in the Type M group (p < 0.001), no significant intraoperative AR difference was found (p = 0.829). The medial epicondyle to joint line and lateral epicondyle to joint line distances showed consistency between measurements in all groups. Joint elevation was significantly higher in the Type M group (3.5 mm (IQR 3.1-3.8) than the Type IA group (2.1 mm (IQR 1.6-2.6) (p < 0.001). Preoperative and postoperative HSS were found to be similar in both groups (p = 0.995 and p = 0.374, respectively).
conclusionsWhile Type IA gonarthrosis did not significantly affect joint line estimation and the Adductor Ratio (AR) showed inconsistency in Type M gonarthrosis, a key finding was the significantly higher joint line elevation observed in Type M compared to Type IA patients. Importantly, this increased elevation did not result in a significant impact on HSS functional scores at two years post-surgery.
