Postoperative anterior knee pain in robot assisted total knee arthroplasty: a propensity score matching analysis.

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
Background and Objective: Anterior knee pain (AKP) remains a prevalent complication following total knee arthroplasty (TKA), affecting 4-60 % of patients. While robot-assisted TKA (RA-TKA) has demonstrated superior precision in prosthesis alignment compared to conventional manual TKA in the medium- and long-term, its impact on postoperative AKP remains underexplored. This study aimed to evaluate the medium- and long-term effects of RA-TKA on AKP intensity, functional outcomes, and knee mobility compared to CM-TKA. Methods: In this retrospective cohort study, obese patients undergoing primary TKA for Kellgren-Lawrence grade 4 osteoarthritis between 2020 and 2023 were included. Propensity score matching balanced preoperative confounders, yielding 88 matched pairs (RA-TKA vs. CM-TKA). Outcomes included AKP intensity (Numeric Rating Scale, NRS), Knee Society Score (KSS), and active knee flexion/extension measured at 3, 6, 9, and 12 months postoperatively. Results: The RA-TKA group exhibited significantly lower AKP intensity at 3 months (17.5 ± 8.1 vs. 24.6 ± 10.7, Conclusion: RA-TKA demonstrated better short-term improvement in both AKP and knee functional capacity compared to standard total knee arthroplasty, and the improvements of knee flexion and extension are significant advantages. Although RA-TKA showed comparable long-term outcomes in knee function and AKP risk assessment to conventional surgery, its clinical significance lies in the critical early postoperative period when over 80 % of AKP events occur within the first 3 months.
