Symmetric versus asymmetric tibial components: A systematic review of comparative studies.

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
backgroundTotal knee arthroplasty (TKA) is a widely performed procedure that significantly enhances patients' quality of life by reducing pain and improving daily function. While the traditional tibial plate design used in TKA has been symmetrical, there has been a recent trend towards using asymmetrical designs. Our study aimed to compare symmetrical and asymmetrical tibial designs, focusing on outcomes related to overhang, malrotation, and tibial coverage.
methodsThis systematic review was conducted in accordance with PRISMA guidelines. A comprehensive search of PubMed, Scopus, Web of Science, and Cochrane databases was carried out up to January 22nd, 2024, to identify comparative studies on symmetrical and asymmetrical designs, as well as those reporting postoperative functional and clinical outcomes. The risk of bias in the included studies was evaluated using the Newcastle-Ottawa Scale (NOS).
resultsThis systematic review included 587 patients from seven comparative studies that met the inclusion criteria. Our findings indicate that asymmetrical tibial components generally provided better outcomes in terms of tibial coverage, malrotation, and overhang. Asymmetrical designs provided greater tibial coverage and reduced posterolateral overhang compared to symmetrical designs, which is essential for minimizing complications like soft tissue irritation and patellar maltracking. Additionally, asymmetrical components were associated with less severe tibial malrotation.
conclusionThis systematic review showed that asymmetrical tibial implants offer better tibial coverage, with less overhang and fewer rotational issues compared to symmetrical implants. As a result, asymmetrical designs in TKA may lower complication rates, enhance patient satisfaction, and improve quality of life post-surgery.
