Pre- and post-operative computed tomography images were applied on 3D software, which were matched and used to calculate the position of femoral and tibial components. Correspondingly, we investigated the relationship between the knee range of motion (ROM) at one-year postoperative follow-up and the position of femoral and tibial components.\nResults\nAt one-year post-UKA, the knee flexion angle was associated with the posterior flexion angle of tibial components. This particular angle was significantly greater in the group with equal or greater postoperative knee ROM compared to preoperative ROM (5.2 ± 2.1°) than in the group with less postoperative knee ROM compared to preoperative ROM (2.6 ± 1.6°, p<0.01). There was no significant difference between both groups in the femoral component position, preoperative posterior slope of the medial tibial plateau, change in the pre- to postoperative posterior tibial slope, and postoperative knee society score.\nConclusion\nThe posterior flexion angle of the tibial component affected the improvement/deterioration of the post surgery knee flexion angle following navigation-assisted UKA. For improved outcomes after UKA using navigation systems, surgeons should aim to achieve a 5° to 8° posterior flexion angle of the tibial component.","subitem_description_type":"Abstract"}]},"item_3_publisher_6":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Springer Nature"}]},"item_3_relation_26":{"attribute_name":"PubMed番号","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"32815031","subitem_relation_type_select":"PMID"}}]},"item_3_relation_28":{"attribute_name":"出版社DOI","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1007/s00590-020-02770-8","subitem_relation_type_select":"DOI"}}]},"item_3_rights_7":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"\"This is a post-peer-review, pre-copyedit version of an article published in \"\"European Journal of Orthopaedic Surgery & Traumatology\"\".
