髌股关节 (PF) 容易受到膝关节手术治疗后急性损伤、慢性疾病和并发症引起的多种病理影响。本研究的目的是描述健康老年人进行三种步态活动时髌骨运动的病例系列测量，确定髌腱角度和力臂，并显示这些量是否与活动相关。利用立体放射成像系统获得 17 名 55 岁以上健康人（8F/9M、66 ± 7.9 岁、75.7 ± 20.5 kg）在进行水平行走、下台阶和旋转转身时的 3D PF 运动学。对于步态周期的相似部分，与其他步态活动（步态 ROM 6.9°± 4.3°，枢轴 ROM 5.7°± 3.3°）相比，下台阶行走时髌骨屈曲 (6.2° ± 5.8) 和平均运动范围 (ROM) (11.0°± 5.9°) 更大，而枢轴转动行走时髌骨倾斜的平均运动范围更大（8.6°±3.9°）。然而，每个受试者在所有活动中都表现出不同的 PF 运动趋势，但有一些明显的例外。重要的是，髌腱角度和力臂的膝关节伸肌机制特征在受试者之间表现出相当大的差异，但基本上不会因活动的变化而改变。受试者之间的差异以及髌骨在下台和枢轴过程中的不同行为强调了对一系列活动进行分析的必要性，以揭示个体对髌骨轨迹不良和骨关节炎的病理和治疗的反应。
The patellofemoral (PF) joint is susceptible to many pathologies resulting from acute injury, chronic disease and complications following surgical treatment of the knee. The objectives of this study were to describe case series measurements of patellar motion in healthy older adults as they performed three gait activities, determine patellar tendon angle and moment arm, and show if these quantities were activity dependent. A stereo radiography system was utilized to obtain the 3D PF kinematics of seventeen healthy people over 55 years of age (8F/9M, 66 ± 7.9 years old, 75.7 ± 20.5 kg) as they performed level walking, a step down, and a pivot turn. For a similar portion of the gait cycle, patellar flexion (6.2° ± 5.8) and average range of motion (ROM) (11.0°± 5.9°) for walking with a step down was greater compared to the other gait activities (gait ROM 6.9°± 4.3°, pivot ROM 5.7°± 3.3°), while the average range of motion for patella tilt was greater during walking with a pivot turn (8.6° ± 3.9°). However, each subject displayed distinct PF kinematic trends during all activities with a few notable exceptions. Importantly, the knee extensor mechanism characteristics of patellar tendon angle and moment arm showed considerable variation across subjects but were largely unaltered by changing activities. The variation between subjects and the different behavior of the patella during the step down and pivot emphasized the need for analysis of a range of activities to reveal individual response to pathology and treatment in patellar maltracking and osteoarthritis.
