Cementless versus cemented fixation in image-based robotic total knee arthroplasty guided by functional knee positioning principles.

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
introductionUnder functional knee positioning (FKPos) principles, residual varus or valgus alignment of the tibia and femur may be maintained, resulting in loading conditions that differ from those observed with mechanical alignment. Consequently, there is a need for evidence regarding implant fixation (cemented or cementless) in this context. This study aimed to evaluate the impact of implant fixation type (cemented versus cementless) on clinical outcomes, complications, and implant survival in robotic-assisted total knee arthroplasty (TKA) guided by FKPos principles.
methodsA retrospective comparative analysis of 393 patients who underwent robotic-assisted primary TKA was performed. Patients were divided into two groups: cemented (n = 85) and cementless (n =276) fixation. Radiographic alignment, functional outcomes using the Knee Society Score (KSS) and Forgotten Joint Score (FJS), complication rates, and implant survival were assessed at a minimum 2-year follow-up. Subgroup analyses based on femoral and tibial fixation types were also conducted.
resultsBoth fixation methods achieved comparable functional outcomes (KSS and FJS) and implant survivorship, with no significant differences in revision rates. Hematomas were significantly more frequent in the cementless group (12.32% vs. 8.24%, p = 0.02). Subgroup analyses of femoral and tibial implants showed no significant differences in functional outcomes. DISCUSSION: This study is the first to assess the influence of fixation type on outcomes in robotic-assisted TKA performed under FKPos principles. Both cemented and cementless fixation methods are safe and effective.
