Three dimensional (3-D) knee motion was measured using a 6-DOF photostereometric system based on high resolution linear CCD camera that was developed in Niigata University. In order to evaluate the relative motion of the femoral component on the tibial surface, the articular distance between femoral and tibial component was calculated and displayed on tibial joint surface. The center of the area which articular distance was less than 0.75mm was defined as the Estimated Contact Point (ECP). The change of ECP during knee flexion was evaluated under different rotational position of the tibial component that included neutral, 10 degrees of internal rotation, and 10 degrees of external rotation. The tracking pattern of the ECP in medial and lateral compartment of the tibial joint surface showed femoral roll-back motion that was seen in physiological knee motion when tibial component was in neutral rotation. When tibial component was set in 10 degrees of internal and external rotaion, same tracking pattern of the ECP was still observed. The amount of the posterior shift of the ECP was almost same between neutral and 10 degrees internal rotation. In the case of 10 degrees external rotation, posterior shift of ECP in medial compartment was less than that of medial, so that the concentration of ECP in posterior part of the medial compartment was observed. This study suggested that in this type of semi-constrained surface replacement TKA system, the rotational laxity of the component not only protect the reverse rotation but also maintain the physiological knee motion pattern such as the roll-back motion. But the concentration of ECP in posterior corner of the medial compartment when the tibial component was set in external rotation, might become the cause of stress concentration that will lead to the wear of polyethylene insert.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "177337", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Suzuki, Yoshihiro"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟医学会"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00182415", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "00290440", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "鈴木, 禎宏"}], "nameIdentifiers": [{"nameIdentifier": "177336", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-09-30"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "113(7-8)_359-366.pdf", "filesize": [{"value": "1.3 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1300000.0, "url": {"label": "113(7-8)_359-366.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/15964/files/113(7-8)_359-366.pdf"}, "version_id": "bd9b20bf-edc2-4d83-b4bc-21cd7749b657"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Total knee arthroplasty", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Three-dimensional knee motion analysis", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rotation of tibial component", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Rotational laxity", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Estimated contact point", "subitem_subject_scheme": "Other"}, {"subitem_subject": "人工膝関節置換術", "subitem_subject_scheme": "Other"}, {"subitem_subject": "3次元膝運動解析", "subitem_subject_scheme": "Other"}, {"subitem_subject": "脛骨コンポーネント回旋設置", "subitem_subject_scheme": "Other"}, {"subitem_subject": "回施許容度", "subitem_subject_scheme": "Other"}, {"subitem_subject": "推定関節接触点", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "人工膝関節置換術における脛骨コンポーネント回旋設置の影響 : 関節面間の推定接触点表示法を用いた検討", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "人工膝関節置換術における脛骨コンポーネント回旋設置の影響 : 関節面間の推定接触点表示法を用いた検討"}, {"subitem_title": "人工膝関節置換術における脛骨コンポーネント回旋設置の影響 : 関節面間の推定接触点表示法を用いた検討", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1094"], "permalink_uri": "http://hdl.handle.net/10191/46792", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-02-24"}, "publish_date": "2017-02-24", "publish_status": "0", "recid": "15964", "relation": {}, "relation_version_is_last": true, "title": ["人工膝関節置換術における脛骨コンポーネント回旋設置の影響 : 関節面間の推定接触点表示法を用いた検討"], "weko_shared_id": null}
