• Note (General): Background: Kneeling is necessary for certain religious and ceremonial occasions, crouching work, and gardening, which many people take part in worldwide. However, there have been few reports about kneeling activities. The purpose of this study was to clarify the kinematics of kneeling.Methods: The subjects were 15 healthy young males. Kneeling activity was analysed within a knee flexion angle from 100° to maximum flexion (maxflex, mean ± SD = 161.3 ± 3.2°). The kinematic and contact point (CP) analyses were performed using a 2D/3D registration method, in which a 3D bone model created from computed tomography images was matched to knee lateral fluoroscopic images and analysed on a personal computer.Results: In the kinematic analysis, the femur translated 37.5 mm posteriorly and rotated 19.8° externally relative to the tibia during the knee flexion phase. During the knee extension phase, the femur translated 36.4 mm anteriorly, which was almost the same amount as in the knee flexion phase. However, the femur rotated only 7.4° internally during the knee extension phase. In the CP analysis, the amount of anterior translation of the CP in the knee extension phase was greater in the medial CP and smaller in the lateral CP than that of posterior translation in the knee flexion phase.Conclusions: In kneeling, there was a difference in the rotational kinematics between the flexion phase and the extension phase. The kinematic difference between the flexion and extension phases may have some effect on the meniscus and articular cartilage.; 長崎大学学位論文 学位記番号:博(医歯薬)甲第1455号 学位授与年月日:令和4年6月1日; Author: Yusuke Nakazoe, Akihiko Yonekura, Hiroyuki Takita, Takeshi Miyaji, Narihiro Okazaki, Ko Chiba, Kenichi Kidera, Takashi Miyamoto, Masato Tomita, Kazuyoshi Gamada and Makoto Osaki; Citation: Journal of Orthopaedic Surgery and Research, 17, art. no. 192; 2022; identifier:Nagasaki University (長崎大学), 博士(医学) (2022-06-01)
