| 520 | 3 | |a Purpose: The purpose of this study was to determine the inter- and intraobserver variability of intraarticular landmark identification for tunnel position calculation in image-free anterior cruciate ligament (ACL) navigation. Methods: In a test/retest scenario, thirteen experienced ACL surgeons (>50 reconstructions year) experienced in image-free ACL navigation were asked to identify the landmarks required for image-free ACL navigation in the same cadaver knee. Landmark positions were registered using a fluoroscopic ACL navigation system. Positions were determined using validated radiological measurement methods. For variability analysis, mean positions, deviations between the test/retest positions, standard deviations (SD) and range were calculated. Results: Interobserver analysis showed a mean variability (SD) for the tibial landmark positions of 3.0mm with deviations of up to 24.3mm (range). Mean femoral landmark variability was 2.9mm (SD) with deviations of up to 11.3mm (range). Intraobserver analysis showed a tibial reproducibility of 2.2mm (SD 2.0mm; range 10.9mm) and a femoral of 1.9mm (SD 1.9mm; range 10.4mm). Conclusion: The data of the presented study suggest that a considerable inter- and intraobserver variability in intraarticular landmark identification exists. Reasonable ranges were found that have to be considered as a potential risk for miscalculation of tunnel positions in image-free ACL reconstruction. Clinical relevance: Landmark acquisition affects tunnel calculation in image-free ACL. Level of evidence: IV. | |
