Use the Right Looking Glass When You Do Caliper-verified Kinematically Aligned TKA!
Open accessAbstract
“Through the Looking-Glass” refers to the Lewis Carroll novel (ie, the sequel to Alice in Wonderland) where Alice crosses over into a “bizarre universe” when she enters the flipped world on the other side of a mirror. The phrase implies unpredictable and strange happenings, a poignant metaphor when the mechanical alignment (MA) total knee arthroplasty (TKA) surgeon confronts kinematic alignment (KA) for the first time!

There are several available methods for identifying native coronal plane morphology, including generic cartilage wear assumptions, use of long leg radiographs, or methods based on advanced imaging.
“There are several available methods for identifying native coronal plane morphology, including generic cartilage wear assumptions, use of long leg radiographs, or methods based on advanced imaging [12–15].”
From Imageless robotic total knee arthroplasty determines similar coronal plane alignment of the knee (CPAK) parameters to long leg radiographs (2024) · cites this paper as [12]
In the main text (page unavailable), Howell describes restoring prearthritic joint lines using a 2 mm allowance for complete cartilage loss and intraoperative caliper measurements. That supports the cartilage-wear element, but the paper does not describe long-leg radiographs or advanced imaging as methods for identifying native coronal morphology; it says this KA approach does not rely on a preoperative radiographic image.

“Several strategies exist for intraoperative determination of native alignment and JLO, including the use of calipers and assumptions about the thickness of lost cartilage, custom cutting blocks, and robotic approaches with or without preoperative imaging [12– 15].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
