Patellofemoral maltracking is a recognized cause of peripatellar pain. Measurements of the patellofemoral relationships during active motion are not available, and clinicians currently rely on observation, palpation, and static radiographic images to evaluate the symptomatic patient. Ultrafast computed tomography (ultrafast CT) offers objective observations of the dynamic influences of muscle contraction on the patellofemoral joint as the knee is actively moved through a range of motion from 90 degrees flexion to full extension. This study reports our initial observations and establishes a range of normal values so that patients with a clinical suspicion of patellar maltracking may be evaluated.
髌股关节轨迹异常是髌周疼痛的一个公认原因。目前无法在主动运动过程中测量髌股关节关系，临床医生目前依靠观察、触诊和静态X线影像来评估有症状的患者。超快计算机断层扫描（超快CT）能在膝关节从90度屈曲到完全伸直的一系列主动运动过程中，对肌肉收缩对髌股关节的动态影响进行客观观察。本研究报告了我们的初步观察结果，并建立了一系列正常值，以便对临床怀疑有髌股关节轨迹异常的患者进行评估。
