- Is the preoperative leg axis similar in radiographic and computer measurements in frontal deformities? Daniel Hernández-Vaquero Medicina Leg axis Navigation Technological assisted systems Computer measurement Introduction: A prerequisite for ensuring a good clinical and functional outcome in total knee arthroplasty is knowing the preoperative leg alignment. This alignment is obtained using a long radiograph including the hip and knee, or a computer algorithm derived from palpation of landmarks and mapping of bone structures. It has been recommended to omit the preoperative radiograph if technology-assisted systems are to be used, but doubts exist regarding the similarity between both measurements, especially in frontal varus or valgus deformities. Material and methods: The preoperative leg alignment was analyzed in 123 patients scheduled for total knee arthroplasty. Thirty-eight had a preoperative valgus axis radiographically, and 85 had a varus axis. A computer program was used to perform the radiographic measurement of the mechanical axis of the leg, and at the start of the procedure, this same measurement was verified with a technology-assisted navigation system (TAS). Results: In the valgus group, the mean preoperative radiographic axis was 169.1º (SD 5.06), while the axis measured using the TAS was 171.9º (SD 3.96) (p=0.009). In the varus group, the mean radiographic axis was 191.9º (SD 5.86), and the axis measured using the TAS was 189.7º (SD 4.84) (p=0.008). The Pearson correlation coefficient comparing both measurements was 0.650 in the varus group and 0.237 in the valgus group (p=0.151) Conclusions: The discrepancy between limb axis measurements obtained radiographically and those obtained with technological aids does not preclude the use of radiography in the preoperative evaluation of total knee arthroplasties. 2026 artículo científico 2695-5075 https://www.redalyc.org/articulo.oa?id=692083787003 https://www.redalyc.org/journal/6920/692083787003/ https://www.redalyc.org/journal/6920/692083787003/html/ https://www.redalyc.org/journal/6920/692083787003/692083787003.epub https://www.redalyc.org/journal/6920/692083787003/movil 10.53986/ibjm.2026.0003 en http://www.redalyc.org/revista.oa?id=6920 Iberoamerican Journal of Medicine application/pdf Hospital San Pedro Iberoamerican Journal of Medicine (España) Num.1 Vol.8
