Mako robot-assisted unicompartmental knee arthroplasty mitigates the impact of surgeon handedness.
Article in Journal of robotic surgery, 2026. 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
Conventional manual unicompartmental knee arthroplasty (CM-UKA) is technically demanding, and surgeon handedness may affect component alignment. Whether Mako robot-assisted UKA (MA-UKA) can mitigate this handedness effect remains unclear. A total of 391 patients undergoing medial UKA performed by five right‑handed surgeons were enrolled in this retrospective analysis. These individuals were allocated to four study arms. Perioperative outcomes, radiographic parameters and functional scores were compared. MA groups had longer operative time but similar tourniquet time, shorter hospital stay, and less blood loss than CM groups (all P<0.05). MA-left and MA-right showed no differences in any radiographic or functional parameters (P>0.05). In contrast, CM-left performed significantly worse than CM-right in terms of implant positioning accuracy (P<0.05). Functional outcomes were better in MA groups, with no side‑related differences. In CM‑UKA, the surgeon's hand dominance markedly influences component alignment precision, with inferior outcomes consistently appearing on the non‑dominant side. MA-UKA mitigates this handedness bias, achieving equally high accuracy on both sides, while also reducing blood loss, shortening hospital stay, and improving early functional recovery.
