Fig. 3From: Intra- and inter‐observer reliability of implant positioning evaluation on a CT-based three‐dimensional postoperative matching system for total knee arthroplastyExperimental design and analyses. Each examiner independently performed the measurement of sagittal and coronal alignments twice for all images, with at least four weeks between measurements. The intra-observer ICC was calculated for each of the three observers, and the inter-observer ICC was calculated using the average of the two measurements of each observer. Implant alignment measurements were compared between the traditional mechanical axis and the implant-based axisBack to article page
