Accuracy verification of anterior cruciate ligament anchor point locating under the guidance of 3D model and AR navigation
摘要
Abstract
Objective To investigate the precision and clinical practicability of anchor point locating under the guidance of augmented reality (AR) navigation for anterior cruciate ligament (ACL) reconstruction.Methods A cube model was made by 3D print which contained some concentric circles of different diameters to be the target.Fifty orthopedists were chosen and numbered from 1 to 50 to locate with AR guidance.Finally,the results of precision and score of satisfaction were analyzed.Results The location precision guided by AR in different diameter concentric circle were 74％ (0.25 cm),78％ (0.5 cm),83％ (0.75 cm),86％ (1.0 cm),89％ (1.25 cm),96％ (1.5 cm) respectively.The average satisfaction score of the orthopedists' was (8.7 ± 1.3).Conclusion Anchor point locating under the guidance of AR navigation is a feasible and effect method for clinical ACL reconstruction,which can observe the relations of the anchor point and the adjacent structure in real time.关键词
